Understanding Contamination and Paths to Exposure

Risk is a measurement of the likelihood that people plants or animals may experience negative effects as a result of their exposure to contamination Risk factors are considered to be the type of contaminant its concentration and the duration and nature of contact or exposure

The Air Force Center for Engineering and the Environment (AFCEE) Installation Restoration Program (IRP) is one of several organizations that address ongoing concerns of risk and public health for those who reside near the Massachusetts Military Reservation (MMR) in the surrounding towns of Bourne Falmouth Mashpee and Sandwich

R I S K

AFCEE is currently involved with 80 locations on the MMR that have been investigated and 11 groundwater plumes are undergoing treatment One plume and additional areas are being monitored AFCEE has taken appropriate measures to clean up and restore contaminated soil and groundwater

AFCEE the US Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (MassDEP) have and continue to make efforts to eliminate exposure pathways that could put people at risk from base-related contamination In areas potentially affected by groundwater contamination residences have been connected to municipal water supplies AFCEE initiated a program in 2008 to validate the status and safety of existing private wells in plume areas since some of these wells could still be used for a potable water source andor for outside watering purposes Wells that continue to be used in areas near plumes are tested free of charge to homeowners Water in nearby recreational ponds (Ashumet Johns Coonamessett Deep Jenkins Round and Snake Ponds) is tested twice during the recreational season with results to date showing no base-related contaminants Potential impacts on ecosystems in ponds vernal pools wetlands rivers and salt water harbors are also monitored Other actions to eliminate exposure pathways are addressing source areas and constructing treatment systems to clean up the plumes These systems are monitored to ensure that no unsafe levels of contaminants are reintroduced back into the environment when treated water is returned to the aquifer or when soil is cleaned

If there is no exposure there is no health risk

Exposure can only occur if there is a pathway for the contaminant to travel from the source to people plants or animals Exposure pathways include

1 Ingestion (drinking or eating contaminated water or food)

2 Dermal contact (touching contaminated soil or water eg showering swimming)

3 Inhalation (breathing in contaminated vapors of chemicals that evaporate into air)

Different routes of exposure to a contaminant can result in different health concerns The following factors and characteristics determine the type and severity of health effects that may occur as a result of exposure to contaminants

bull Concentration (how much)

bull Carcinogenic or noncarcinogenic contaminant

bull Frequency (number of days per year)

bull Age (child or adult receptor)

bull Duration (number of years)

bull Specific sensitive groups (eg pregnant women)

bull Toxicity (characteristics of the chemical)

In order for there to be a risk there must first be an exposure to a contaminant The amount of risk to onersquos health depends on the duration of exposure the toxicity of the particular contaminant the concentration of the contaminant and various personal factors The primary potential health risk at and around MMR is from drinking contaminated groundwater No exposure means no risk

Source areas are located on base and most have already been cleaned up The majority of residences around the base are connected to municipal water For those residences not connected to municipal water and located in an area that might be potentially at risk AFCEE conducts a voluntary residential well sampling program Most of the residential wells in the area draw water from a shallow depth or zone in the upper portion of the aquifer while most of the plumes associated with MMR are deep mdash as much as 100 to 200 feet below the ground surface If there is no possibility of exposure to contaminants and there is no reason to believe that there will be in the future the contaminants do not pose a risk to human health or the environment Since AFCEE began managing the IRP at MMR there have been no known detections of plume-related contaminants in residential private wells above safe drinking water limits

AFCEE has provided more than 1100 conversions from private well systems to municipal water in the four Upper Cape towns in the plume areas but many residential and irrigation wells were not closed at the time of those conversions As part of AFCEErsquos Land Use Control Program if homeowners are interested in keeping and using their wells a risk assessment will be completed This would involve an evaluation of the depth of the well in proximity to the plume and may include testing of the well water AFCEE will offer free decommissioning of any well that is found to present an unacceptable risk (this involves disconnecting piping to the house and filling in the well casing) If decommissioning is not accepted AFCEE will take other steps to insure protectiveness such as requesting assistance from the appropriate Board of Health to prevent exposure offering bottled water (if the well is used for drinking) installing a treatment system on the well or providing a municipal water supply connection

Since AFCEE began managing the IRP at MMR there have been no known detections of plume-related contaminants in residential private wells above safe drinking water limits

Some terms you need to know

COC = Contaminant of Concern

gpm = Gallons Per Minute

GW-1 = State default cleanup value to be used in lieu of site-specific risk-based level

MCL = Maximum Contaminant Level A maximum contaminant level is the highest level of a contaminant that is allowed in drinking water MCLs are enforceable standards by the EPA

MMCL = Massachusetts Maximum Contaminant Level In cases where the MMCL is lower than EPArsquos MCL the more stringent (lower) standard is applied as part of AFCEErsquos analysis and cleanup actions

MG = Million Gallons

ROD = Record of Decision

SPEIM = System Performance and Ecological Impact Monitoring

microgL = Micrograms Per Liter A microgram per liter is approximately 1 drop in 22000 gallons

The most toxic COCs are those with the lowest target cleanup levels For example a half-drop of EDB would conceptually bring an Olympic size swimming poolrsquos concentration equal to the EDB MMCL of 002 microgL Similarly it would take 1 frac34 teaspoons of TCE to bring an Olympic size swimming poolrsquos concentration equal to the TCE MCL of 5 microgL

At MMR there are a number of COCs Contaminant of Concern Cleanup Level Type of Contaminant trichloroethene (TCE) 5 microgL solvent perchloroethene (PCE) 5 microgL solvent carbon tetrachloride (CCl4) 5 microgL solvent ethylene dibromide (EDB) 002 microgL fuel-related compound benzene 5 microgL fuel-related compound vinyl chloride (breakdown product of reductive chlorination)

Source Areas

A source area is an area considered to be a possible ldquosourcerdquo of contamination to the environment These areas contain contaminated soil as a result of past spills or other activities and depending on the type and concentration of contamination could threaten the underlying groundwater or the plants animals or humans who come into direct contact with the contaminated soil

There are 80 locations on the MMR that have been evaluated as part of the Air Force cleanup efforts Many of those locations were confirmed as source areas that contributed to soil andor groundwater contamination at some point in the past The current status of the source areas is shown in the graphic below Contaminated soil is either treated in place or excavated and transported to an approved facility for on-base or off-base treatment andor disposal For contamination that is too deep to safely excavate in-place soil cleanup is conducted This involves a treatment called soil vapor extraction (SVE) In the SVE process pipelines are used to apply a vacuum to the soil and remove the contaminants as vapor which is then treated with carbon in a vapor treatment system

In several cases source areas have contributed to groundwater contamination at concentrations exceeding MCLs or MMCLs thereby creating a groundwater plume

In the summer of 2007 EPA published in the Federal Register a Notice of Intent (NOI) for Partial Deletion from the Otis Air National Guard BaseCamp Edwards Superfund Site (MMR) The NOI covered 61 source areas on the MMR All of these sites have been investigated and where needed cleanup actions were completed Determinations of no-further-response and no-further-risk to human health and the environment have been made for these sites The sites that are associated with groundwater plumes have not been included even though investigation andor cleanup may have been completed

Although some sites are located within plume boundaries from the two-dimensional perspective site investigation data and plume data demonstrate that these sites are not connected to plumes Therefore EPA believes that it is acceptable to partially delist a surface site while a groundwater plume is undergoing cleanup The partial deletion does not include groundwater plumes where cleanup levels have not been met or sites where investigation or cleanup is ongoing

In late 2007 this partial deletion was finalized If any new contamination information becomes available EPA may reopen any site that was previously deleted

Where did this contamination come from

Since the early 1900s MMR has been used for military purposes including troop training and maneuvers military aircraft operations vehicle maintenance and support Some activities required the use of petroleum products solvents and other hazardous materials It was common practice for many years at the MMR as it was at other military bases and industrial facilities throughout the country to dispose of wastes in unlined landfills and drywells to dump and burn them at firefighter-training areas or to rinse them down drains In addition pipeline breaks and accidental spills occurred at MMR Today the use and disposal of hazardous materials is strictly managed and regulated at MMR to be protective of the environment The IRP is the program that cleans up soil and groundwater contamination resulting from historic use of the southern portion of MMR AFCEE is the agency that is responsible for the IRP EPA and MassDEP oversee AFCEErsquos cleanup effort at MMR

The US Army Environmental Commandrsquos Impact Area Groundwater Study Program (IAGWSP) is responsible for addressing soil and groundwater contamination from historic activities at Camp Edwards on the northern portion of MMR The phone number for the IAGWSP office is (508) 968-5630

How are the groundwater plumes treated

Aplume is a body of groundwater containing contaminants that exceed federal andor state safe drinking water standards When chemicals from source areas travel downward through the sandy soils they eventually reach the aquifer where they begin to dissolve Once dissolved they begin to move with the groundwater thus creating a plume

To actively treat groundwater contamination extraction wells are placed within a plume to pump the contaminated groundwater from the aquifer to a treatment plant where the water is filtered through carbon held in large vessels (The used carbon is recycled off site and reused at MMR) Treated water is returned to the aquifer using reinjection wells or infiltration galleries while treatment facilities at river systems utilize bubblers

The IRP is currently addressing 12 groundwater plumes Many of these plumes are located beyond the MMR boundary and are currently in various stages of study and cleanup At this time systems are treating approximately 14 million gallons of groundwater per day Computer modeling suggests that it may take more than 30 years to fully remediate all of the groundwater contamination associated with MMR Several plumes have shown dramatic decreases in size and contaminant concentrations due to years of groundwater treatment actions Plumes and treatment systems are continually being monitored and optimized to reduce the overall cleanup time

Eleven plumes are undergoing groundwater cleanup Ashumet Valley Chemical Spill 4 (CS-4) CS-10 CS-20 CS-21 CS-23 Fuel Spill 1 (FS-1) FS-12 FS-28 FS-29 and Landfill 1 (LF-1)

One plume CS-19 is in long-term monitoring LF-2 and Storm Drain 5 (SD-5) two sites where the groundwater contamination no longer meets the definition of a plume are also in long-term monitoring

Treated water is returned to the aquifer using reinjection wells or infiltration galleries Treatment facilities at river systems utilize bubblers

Treatment plants clean up extracted contaminated groundwater by filtering it through carbon held in large vessels

Extraction wells are placed within a plume to pump contaminated groundwater from the aquifer to the treatment plant

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Understanding Contamination and Paths to Exposure

Risk is a measurement of the likelihood that people plants or animals may experience negative effects as a result of their exposure to contamination Risk factors are considered to be the type of contaminant its concentration and the duration and nature of contact or exposure

The Air Force Center for Engineering and the Environment (AFCEE) Installation Restoration Program (IRP) is one of several organizations that address ongoing concerns of risk and public health for those who reside near the Massachusetts Military Reservation (MMR) in the surrounding towns of Bourne Falmouth Mashpee and Sandwich

R I S K

AFCEE is currently involved with 80 locations on the MMR that have been investigated and 11 groundwater plumes are undergoing treatment One plume and additional areas are being monitored AFCEE has taken appropriate measures to clean up and restore contaminated soil and groundwater

AFCEE the US Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (MassDEP) have and continue to make efforts to eliminate exposure pathways that could put people at risk from base-related contamination In areas potentially affected by groundwater contamination residences have been connected to municipal water supplies AFCEE initiated a program in 2008 to validate the status and safety of existing private wells in plume areas since some of these wells could still be used for a potable water source andor for outside watering purposes Wells that continue to be used in areas near plumes are tested free of charge to homeowners Water in nearby recreational ponds (Ashumet Johns Coonamessett Deep Jenkins Round and Snake Ponds) is tested twice during the recreational season with results to date showing no base-related contaminants Potential impacts on ecosystems in ponds vernal pools wetlands rivers and salt water harbors are also monitored Other actions to eliminate exposure pathways are addressing source areas and constructing treatment systems to clean up the plumes These systems are monitored to ensure that no unsafe levels of contaminants are reintroduced back into the environment when treated water is returned to the aquifer or when soil is cleaned

If there is no exposure there is no health risk

Exposure can only occur if there is a pathway for the contaminant to travel from the source to people plants or animals Exposure pathways include

1 Ingestion (drinking or eating contaminated water or food)

2 Dermal contact (touching contaminated soil or water eg showering swimming)

3 Inhalation (breathing in contaminated vapors of chemicals that evaporate into air)

Different routes of exposure to a contaminant can result in different health concerns The following factors and characteristics determine the type and severity of health effects that may occur as a result of exposure to contaminants

bull Concentration (how much)

bull Carcinogenic or noncarcinogenic contaminant

bull Frequency (number of days per year)

bull Age (child or adult receptor)

bull Duration (number of years)

bull Specific sensitive groups (eg pregnant women)

bull Toxicity (characteristics of the chemical)

Information Booklet - April 2010 2

Massachusetts Military ReservationMassachusetts Military Reservation

In order for there to be a risk there must first be an exposure to a contaminant The amount of risk to onersquos health depends on the duration of exposure the toxicity of the particular contaminant the concentration of the contaminant and various personal factors The primary potential health risk at and around MMR is from drinking contaminated groundwater No exposure means no risk

Source areas are located on base and most have already been cleaned up The majority of residences around the base are connected to municipal water For those residences not connected to municipal water and located in an area that might be potentially at risk AFCEE conducts a voluntary residential well sampling program Most of the residential wells in the area draw water from a shallow depth or zone in the upper portion of the aquifer while most of the plumes associated with MMR are deep mdash as much as 100 to 200 feet below the ground surface If there is no possibility of exposure to contaminants and there is no reason to believe that there will be in the future the contaminants do not pose a risk to human health or the environment Since AFCEE began managing the IRP at MMR there have been no known detections of plume-related contaminants in residential private wells above safe drinking water limits

AFCEE has provided more than 1100 conversions from private well systems to municipal water in the four Upper Cape towns in the plume areas but many residential and irrigation wells were not closed at the time of those conversions As part of AFCEErsquos Land Use Control Program if homeowners are interested in keeping and using their wells a risk assessment will be completed This would involve an evaluation of the depth of the well in proximity to the plume and may include testing of the well water AFCEE will offer free decommissioning of any well that is found to present an unacceptable risk (this involves disconnecting piping to the house and filling in the well casing) If decommissioning is not accepted AFCEE will take other steps to insure protectiveness such as requesting assistance from the appropriate Board of Health to prevent exposure offering bottled water (if the well is used for drinking) installing a treatment system on the well or providing a municipal water supply connection

Since AFCEE began managing the IRP at MMR there have been no known detections of plume-related contaminants in residential private wells above safe drinking water limits

Some terms you need to know

COC = Contaminant of Concern

gpm = Gallons Per Minute

GW-1 = State default cleanup value to be used in lieu of site-specific risk-based level

MCL = Maximum Contaminant Level A maximum contaminant level is the highest level of a contaminant that is allowed in drinking water MCLs are enforceable standards by the EPA

MMCL = Massachusetts Maximum Contaminant Level In cases where the MMCL is lower than EPArsquos MCL the more stringent (lower) standard is applied as part of AFCEErsquos analysis and cleanup actions

MG = Million Gallons

ROD = Record of Decision

SPEIM = System Performance and Ecological Impact Monitoring

microgL = Micrograms Per Liter A microgram per liter is approximately 1 drop in 22000 gallons

The most toxic COCs are those with the lowest target cleanup levels For example a half-drop of EDB would conceptually bring an Olympic size swimming poolrsquos concentration equal to the EDB MMCL of 002 microgL Similarly it would take 1 frac34 teaspoons of TCE to bring an Olympic size swimming poolrsquos concentration equal to the TCE MCL of 5 microgL

At MMR there are a number of COCs Contaminant of Concern Cleanup Level Type of Contaminant trichloroethene (TCE) 5 microgL solvent perchloroethene (PCE) 5 microgL solvent carbon tetrachloride (CCl4) 5 microgL solvent ethylene dibromide (EDB) 002 microgL fuel-related compound benzene 5 microgL fuel-related compound vinyl chloride (breakdown product of reductive chlorination)

Source Areas

A source area is an area considered to be a possible ldquosourcerdquo of contamination to the environment These areas contain contaminated soil as a result of past spills or other activities and depending on the type and concentration of contamination could threaten the underlying groundwater or the plants animals or humans who come into direct contact with the contaminated soil

There are 80 locations on the MMR that have been evaluated as part of the Air Force cleanup efforts Many of those locations were confirmed as source areas that contributed to soil andor groundwater contamination at some point in the past The current status of the source areas is shown in the graphic below Contaminated soil is either treated in place or excavated and transported to an approved facility for on-base or off-base treatment andor disposal For contamination that is too deep to safely excavate in-place soil cleanup is conducted This involves a treatment called soil vapor extraction (SVE) In the SVE process pipelines are used to apply a vacuum to the soil and remove the contaminants as vapor which is then treated with carbon in a vapor treatment system

In several cases source areas have contributed to groundwater contamination at concentrations exceeding MCLs or MMCLs thereby creating a groundwater plume

In the summer of 2007 EPA published in the Federal Register a Notice of Intent (NOI) for Partial Deletion from the Otis Air National Guard BaseCamp Edwards Superfund Site (MMR) The NOI covered 61 source areas on the MMR All of these sites have been investigated and where needed cleanup actions were completed Determinations of no-further-response and no-further-risk to human health and the environment have been made for these sites The sites that are associated with groundwater plumes have not been included even though investigation andor cleanup may have been completed

Although some sites are located within plume boundaries from the two-dimensional perspective site investigation data and plume data demonstrate that these sites are not connected to plumes Therefore EPA believes that it is acceptable to partially delist a surface site while a groundwater plume is undergoing cleanup The partial deletion does not include groundwater plumes where cleanup levels have not been met or sites where investigation or cleanup is ongoing

In late 2007 this partial deletion was finalized If any new contamination information becomes available EPA may reopen any site that was previously deleted

Where did this contamination come from

Since the early 1900s MMR has been used for military purposes including troop training and maneuvers military aircraft operations vehicle maintenance and support Some activities required the use of petroleum products solvents and other hazardous materials It was common practice for many years at the MMR as it was at other military bases and industrial facilities throughout the country to dispose of wastes in unlined landfills and drywells to dump and burn them at firefighter-training areas or to rinse them down drains In addition pipeline breaks and accidental spills occurred at MMR Today the use and disposal of hazardous materials is strictly managed and regulated at MMR to be protective of the environment The IRP is the program that cleans up soil and groundwater contamination resulting from historic use of the southern portion of MMR AFCEE is the agency that is responsible for the IRP EPA and MassDEP oversee AFCEErsquos cleanup effort at MMR

The US Army Environmental Commandrsquos Impact Area Groundwater Study Program (IAGWSP) is responsible for addressing soil and groundwater contamination from historic activities at Camp Edwards on the northern portion of MMR The phone number for the IAGWSP office is (508) 968-5630

How are the groundwater plumes treated

Aplume is a body of groundwater containing contaminants that exceed federal andor state safe drinking water standards When chemicals from source areas travel downward through the sandy soils they eventually reach the aquifer where they begin to dissolve Once dissolved they begin to move with the groundwater thus creating a plume

To actively treat groundwater contamination extraction wells are placed within a plume to pump the contaminated groundwater from the aquifer to a treatment plant where the water is filtered through carbon held in large vessels (The used carbon is recycled off site and reused at MMR) Treated water is returned to the aquifer using reinjection wells or infiltration galleries while treatment facilities at river systems utilize bubblers

The IRP is currently addressing 12 groundwater plumes Many of these plumes are located beyond the MMR boundary and are currently in various stages of study and cleanup At this time systems are treating approximately 14 million gallons of groundwater per day Computer modeling suggests that it may take more than 30 years to fully remediate all of the groundwater contamination associated with MMR Several plumes have shown dramatic decreases in size and contaminant concentrations due to years of groundwater treatment actions Plumes and treatment systems are continually being monitored and optimized to reduce the overall cleanup time

Eleven plumes are undergoing groundwater cleanup Ashumet Valley Chemical Spill 4 (CS-4) CS-10 CS-20 CS-21 CS-23 Fuel Spill 1 (FS-1) FS-12 FS-28 FS-29 and Landfill 1 (LF-1)

One plume CS-19 is in long-term monitoring LF-2 and Storm Drain 5 (SD-5) two sites where the groundwater contamination no longer meets the definition of a plume are also in long-term monitoring

Treated water is returned to the aquifer using reinjection wells or infiltration galleries Treatment facilities at river systems utilize bubblers

Treatment plants clean up extracted contaminated groundwater by filtering it through carbon held in large vessels

Extraction wells are placed within a plume to pump contaminated groundwater from the aquifer to the treatment plant

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

In order for there to be a risk there must first be an exposure to a contaminant The amount of risk to onersquos health depends on the duration of exposure the toxicity of the particular contaminant the concentration of the contaminant and various personal factors The primary potential health risk at and around MMR is from drinking contaminated groundwater No exposure means no risk

Source areas are located on base and most have already been cleaned up The majority of residences around the base are connected to municipal water For those residences not connected to municipal water and located in an area that might be potentially at risk AFCEE conducts a voluntary residential well sampling program Most of the residential wells in the area draw water from a shallow depth or zone in the upper portion of the aquifer while most of the plumes associated with MMR are deep mdash as much as 100 to 200 feet below the ground surface If there is no possibility of exposure to contaminants and there is no reason to believe that there will be in the future the contaminants do not pose a risk to human health or the environment Since AFCEE began managing the IRP at MMR there have been no known detections of plume-related contaminants in residential private wells above safe drinking water limits

AFCEE has provided more than 1100 conversions from private well systems to municipal water in the four Upper Cape towns in the plume areas but many residential and irrigation wells were not closed at the time of those conversions As part of AFCEErsquos Land Use Control Program if homeowners are interested in keeping and using their wells a risk assessment will be completed This would involve an evaluation of the depth of the well in proximity to the plume and may include testing of the well water AFCEE will offer free decommissioning of any well that is found to present an unacceptable risk (this involves disconnecting piping to the house and filling in the well casing) If decommissioning is not accepted AFCEE will take other steps to insure protectiveness such as requesting assistance from the appropriate Board of Health to prevent exposure offering bottled water (if the well is used for drinking) installing a treatment system on the well or providing a municipal water supply connection

Since AFCEE began managing the IRP at MMR there have been no known detections of plume-related contaminants in residential private wells above safe drinking water limits

Some terms you need to know

COC = Contaminant of Concern

gpm = Gallons Per Minute

GW-1 = State default cleanup value to be used in lieu of site-specific risk-based level

MCL = Maximum Contaminant Level A maximum contaminant level is the highest level of a contaminant that is allowed in drinking water MCLs are enforceable standards by the EPA

MMCL = Massachusetts Maximum Contaminant Level In cases where the MMCL is lower than EPArsquos MCL the more stringent (lower) standard is applied as part of AFCEErsquos analysis and cleanup actions

MG = Million Gallons

ROD = Record of Decision

SPEIM = System Performance and Ecological Impact Monitoring

microgL = Micrograms Per Liter A microgram per liter is approximately 1 drop in 22000 gallons

The most toxic COCs are those with the lowest target cleanup levels For example a half-drop of EDB would conceptually bring an Olympic size swimming poolrsquos concentration equal to the EDB MMCL of 002 microgL Similarly it would take 1 frac34 teaspoons of TCE to bring an Olympic size swimming poolrsquos concentration equal to the TCE MCL of 5 microgL

Source Areas

A source area is an area considered to be a possible ldquosourcerdquo of contamination to the environment These areas contain contaminated soil as a result of past spills or other activities and depending on the type and concentration of contamination could threaten the underlying groundwater or the plants animals or humans who come into direct contact with the contaminated soil

There are 80 locations on the MMR that have been evaluated as part of the Air Force cleanup efforts Many of those locations were confirmed as source areas that contributed to soil andor groundwater contamination at some point in the past The current status of the source areas is shown in the graphic below Contaminated soil is either treated in place or excavated and transported to an approved facility for on-base or off-base treatment andor disposal For contamination that is too deep to safely excavate in-place soil cleanup is conducted This involves a treatment called soil vapor extraction (SVE) In the SVE process pipelines are used to apply a vacuum to the soil and remove the contaminants as vapor which is then treated with carbon in a vapor treatment system

In several cases source areas have contributed to groundwater contamination at concentrations exceeding MCLs or MMCLs thereby creating a groundwater plume

In the summer of 2007 EPA published in the Federal Register a Notice of Intent (NOI) for Partial Deletion from the Otis Air National Guard BaseCamp Edwards Superfund Site (MMR) The NOI covered 61 source areas on the MMR All of these sites have been investigated and where needed cleanup actions were completed Determinations of no-further-response and no-further-risk to human health and the environment have been made for these sites The sites that are associated with groundwater plumes have not been included even though investigation andor cleanup may have been completed

Although some sites are located within plume boundaries from the two-dimensional perspective site investigation data and plume data demonstrate that these sites are not connected to plumes Therefore EPA believes that it is acceptable to partially delist a surface site while a groundwater plume is undergoing cleanup The partial deletion does not include groundwater plumes where cleanup levels have not been met or sites where investigation or cleanup is ongoing

In late 2007 this partial deletion was finalized If any new contamination information becomes available EPA may reopen any site that was previously deleted

Where did this contamination come from

Since the early 1900s MMR has been used for military purposes including troop training and maneuvers military aircraft operations vehicle maintenance and support Some activities required the use of petroleum products solvents and other hazardous materials It was common practice for many years at the MMR as it was at other military bases and industrial facilities throughout the country to dispose of wastes in unlined landfills and drywells to dump and burn them at firefighter-training areas or to rinse them down drains In addition pipeline breaks and accidental spills occurred at MMR Today the use and disposal of hazardous materials is strictly managed and regulated at MMR to be protective of the environment The IRP is the program that cleans up soil and groundwater contamination resulting from historic use of the southern portion of MMR AFCEE is the agency that is responsible for the IRP EPA and MassDEP oversee AFCEErsquos cleanup effort at MMR

The US Army Environmental Commandrsquos Impact Area Groundwater Study Program (IAGWSP) is responsible for addressing soil and groundwater contamination from historic activities at Camp Edwards on the northern portion of MMR The phone number for the IAGWSP office is (508) 968-5630

How are the groundwater plumes treated

Aplume is a body of groundwater containing contaminants that exceed federal andor state safe drinking water standards When chemicals from source areas travel downward through the sandy soils they eventually reach the aquifer where they begin to dissolve Once dissolved they begin to move with the groundwater thus creating a plume

To actively treat groundwater contamination extraction wells are placed within a plume to pump the contaminated groundwater from the aquifer to a treatment plant where the water is filtered through carbon held in large vessels (The used carbon is recycled off site and reused at MMR) Treated water is returned to the aquifer using reinjection wells or infiltration galleries while treatment facilities at river systems utilize bubblers

The IRP is currently addressing 12 groundwater plumes Many of these plumes are located beyond the MMR boundary and are currently in various stages of study and cleanup At this time systems are treating approximately 14 million gallons of groundwater per day Computer modeling suggests that it may take more than 30 years to fully remediate all of the groundwater contamination associated with MMR Several plumes have shown dramatic decreases in size and contaminant concentrations due to years of groundwater treatment actions Plumes and treatment systems are continually being monitored and optimized to reduce the overall cleanup time

Eleven plumes are undergoing groundwater cleanup Ashumet Valley Chemical Spill 4 (CS-4) CS-10 CS-20 CS-21 CS-23 Fuel Spill 1 (FS-1) FS-12 FS-28 FS-29 and Landfill 1 (LF-1)

One plume CS-19 is in long-term monitoring LF-2 and Storm Drain 5 (SD-5) two sites where the groundwater contamination no longer meets the definition of a plume are also in long-term monitoring

Treated water is returned to the aquifer using reinjection wells or infiltration galleries Treatment facilities at river systems utilize bubblers

Treatment plants clean up extracted contaminated groundwater by filtering it through carbon held in large vessels

Extraction wells are placed within a plume to pump contaminated groundwater from the aquifer to the treatment plant

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

Some terms you need to know

COC = Contaminant of Concern

gpm = Gallons Per Minute

GW-1 = State default cleanup value to be used in lieu of site-specific risk-based level

MCL = Maximum Contaminant Level A maximum contaminant level is the highest level of a contaminant that is allowed in drinking water MCLs are enforceable standards by the EPA

MMCL = Massachusetts Maximum Contaminant Level In cases where the MMCL is lower than EPArsquos MCL the more stringent (lower) standard is applied as part of AFCEErsquos analysis and cleanup actions

MG = Million Gallons

ROD = Record of Decision

SPEIM = System Performance and Ecological Impact Monitoring

microgL = Micrograms Per Liter A microgram per liter is approximately 1 drop in 22000 gallons

The most toxic COCs are those with the lowest target cleanup levels For example a half-drop of EDB would conceptually bring an Olympic size swimming poolrsquos concentration equal to the EDB MMCL of 002 microgL Similarly it would take 1 frac34 teaspoons of TCE to bring an Olympic size swimming poolrsquos concentration equal to the TCE MCL of 5 microgL

Source Areas

A source area is an area considered to be a possible ldquosourcerdquo of contamination to the environment These areas contain contaminated soil as a result of past spills or other activities and depending on the type and concentration of contamination could threaten the underlying groundwater or the plants animals or humans who come into direct contact with the contaminated soil

There are 80 locations on the MMR that have been evaluated as part of the Air Force cleanup efforts Many of those locations were confirmed as source areas that contributed to soil andor groundwater contamination at some point in the past The current status of the source areas is shown in the graphic below Contaminated soil is either treated in place or excavated and transported to an approved facility for on-base or off-base treatment andor disposal For contamination that is too deep to safely excavate in-place soil cleanup is conducted This involves a treatment called soil vapor extraction (SVE) In the SVE process pipelines are used to apply a vacuum to the soil and remove the contaminants as vapor which is then treated with carbon in a vapor treatment system

In several cases source areas have contributed to groundwater contamination at concentrations exceeding MCLs or MMCLs thereby creating a groundwater plume

In the summer of 2007 EPA published in the Federal Register a Notice of Intent (NOI) for Partial Deletion from the Otis Air National Guard BaseCamp Edwards Superfund Site (MMR) The NOI covered 61 source areas on the MMR All of these sites have been investigated and where needed cleanup actions were completed Determinations of no-further-response and no-further-risk to human health and the environment have been made for these sites The sites that are associated with groundwater plumes have not been included even though investigation andor cleanup may have been completed

Although some sites are located within plume boundaries from the two-dimensional perspective site investigation data and plume data demonstrate that these sites are not connected to plumes Therefore EPA believes that it is acceptable to partially delist a surface site while a groundwater plume is undergoing cleanup The partial deletion does not include groundwater plumes where cleanup levels have not been met or sites where investigation or cleanup is ongoing

In late 2007 this partial deletion was finalized If any new contamination information becomes available EPA may reopen any site that was previously deleted

Where did this contamination come from

Since the early 1900s MMR has been used for military purposes including troop training and maneuvers military aircraft operations vehicle maintenance and support Some activities required the use of petroleum products solvents and other hazardous materials It was common practice for many years at the MMR as it was at other military bases and industrial facilities throughout the country to dispose of wastes in unlined landfills and drywells to dump and burn them at firefighter-training areas or to rinse them down drains In addition pipeline breaks and accidental spills occurred at MMR Today the use and disposal of hazardous materials is strictly managed and regulated at MMR to be protective of the environment The IRP is the program that cleans up soil and groundwater contamination resulting from historic use of the southern portion of MMR AFCEE is the agency that is responsible for the IRP EPA and MassDEP oversee AFCEErsquos cleanup effort at MMR

The US Army Environmental Commandrsquos Impact Area Groundwater Study Program (IAGWSP) is responsible for addressing soil and groundwater contamination from historic activities at Camp Edwards on the northern portion of MMR The phone number for the IAGWSP office is (508) 968-5630

How are the groundwater plumes treated

Aplume is a body of groundwater containing contaminants that exceed federal andor state safe drinking water standards When chemicals from source areas travel downward through the sandy soils they eventually reach the aquifer where they begin to dissolve Once dissolved they begin to move with the groundwater thus creating a plume

To actively treat groundwater contamination extraction wells are placed within a plume to pump the contaminated groundwater from the aquifer to a treatment plant where the water is filtered through carbon held in large vessels (The used carbon is recycled off site and reused at MMR) Treated water is returned to the aquifer using reinjection wells or infiltration galleries while treatment facilities at river systems utilize bubblers

The IRP is currently addressing 12 groundwater plumes Many of these plumes are located beyond the MMR boundary and are currently in various stages of study and cleanup At this time systems are treating approximately 14 million gallons of groundwater per day Computer modeling suggests that it may take more than 30 years to fully remediate all of the groundwater contamination associated with MMR Several plumes have shown dramatic decreases in size and contaminant concentrations due to years of groundwater treatment actions Plumes and treatment systems are continually being monitored and optimized to reduce the overall cleanup time

Eleven plumes are undergoing groundwater cleanup Ashumet Valley Chemical Spill 4 (CS-4) CS-10 CS-20 CS-21 CS-23 Fuel Spill 1 (FS-1) FS-12 FS-28 FS-29 and Landfill 1 (LF-1)

One plume CS-19 is in long-term monitoring LF-2 and Storm Drain 5 (SD-5) two sites where the groundwater contamination no longer meets the definition of a plume are also in long-term monitoring

Treated water is returned to the aquifer using reinjection wells or infiltration galleries Treatment facilities at river systems utilize bubblers

Treatment plants clean up extracted contaminated groundwater by filtering it through carbon held in large vessels

Extraction wells are placed within a plume to pump contaminated groundwater from the aquifer to the treatment plant

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Source Areas

A source area is an area considered to be a possible ldquosourcerdquo of contamination to the environment These areas contain contaminated soil as a result of past spills or other activities and depending on the type and concentration of contamination could threaten the underlying groundwater or the plants animals or humans who come into direct contact with the contaminated soil

There are 80 locations on the MMR that have been evaluated as part of the Air Force cleanup efforts Many of those locations were confirmed as source areas that contributed to soil andor groundwater contamination at some point in the past The current status of the source areas is shown in the graphic below Contaminated soil is either treated in place or excavated and transported to an approved facility for on-base or off-base treatment andor disposal For contamination that is too deep to safely excavate in-place soil cleanup is conducted This involves a treatment called soil vapor extraction (SVE) In the SVE process pipelines are used to apply a vacuum to the soil and remove the contaminants as vapor which is then treated with carbon in a vapor treatment system

In several cases source areas have contributed to groundwater contamination at concentrations exceeding MCLs or MMCLs thereby creating a groundwater plume

In the summer of 2007 EPA published in the Federal Register a Notice of Intent (NOI) for Partial Deletion from the Otis Air National Guard BaseCamp Edwards Superfund Site (MMR) The NOI covered 61 source areas on the MMR All of these sites have been investigated and where needed cleanup actions were completed Determinations of no-further-response and no-further-risk to human health and the environment have been made for these sites The sites that are associated with groundwater plumes have not been included even though investigation andor cleanup may have been completed

Although some sites are located within plume boundaries from the two-dimensional perspective site investigation data and plume data demonstrate that these sites are not connected to plumes Therefore EPA believes that it is acceptable to partially delist a surface site while a groundwater plume is undergoing cleanup The partial deletion does not include groundwater plumes where cleanup levels have not been met or sites where investigation or cleanup is ongoing

In late 2007 this partial deletion was finalized If any new contamination information becomes available EPA may reopen any site that was previously deleted

Where did this contamination come from

Since the early 1900s MMR has been used for military purposes including troop training and maneuvers military aircraft operations vehicle maintenance and support Some activities required the use of petroleum products solvents and other hazardous materials It was common practice for many years at the MMR as it was at other military bases and industrial facilities throughout the country to dispose of wastes in unlined landfills and drywells to dump and burn them at firefighter-training areas or to rinse them down drains In addition pipeline breaks and accidental spills occurred at MMR Today the use and disposal of hazardous materials is strictly managed and regulated at MMR to be protective of the environment The IRP is the program that cleans up soil and groundwater contamination resulting from historic use of the southern portion of MMR AFCEE is the agency that is responsible for the IRP EPA and MassDEP oversee AFCEErsquos cleanup effort at MMR

The US Army Environmental Commandrsquos Impact Area Groundwater Study Program (IAGWSP) is responsible for addressing soil and groundwater contamination from historic activities at Camp Edwards on the northern portion of MMR The phone number for the IAGWSP office is (508) 968-5630

How are the groundwater plumes treated

Aplume is a body of groundwater containing contaminants that exceed federal andor state safe drinking water standards When chemicals from source areas travel downward through the sandy soils they eventually reach the aquifer where they begin to dissolve Once dissolved they begin to move with the groundwater thus creating a plume

To actively treat groundwater contamination extraction wells are placed within a plume to pump the contaminated groundwater from the aquifer to a treatment plant where the water is filtered through carbon held in large vessels (The used carbon is recycled off site and reused at MMR) Treated water is returned to the aquifer using reinjection wells or infiltration galleries while treatment facilities at river systems utilize bubblers

The IRP is currently addressing 12 groundwater plumes Many of these plumes are located beyond the MMR boundary and are currently in various stages of study and cleanup At this time systems are treating approximately 14 million gallons of groundwater per day Computer modeling suggests that it may take more than 30 years to fully remediate all of the groundwater contamination associated with MMR Several plumes have shown dramatic decreases in size and contaminant concentrations due to years of groundwater treatment actions Plumes and treatment systems are continually being monitored and optimized to reduce the overall cleanup time

Eleven plumes are undergoing groundwater cleanup Ashumet Valley Chemical Spill 4 (CS-4) CS-10 CS-20 CS-21 CS-23 Fuel Spill 1 (FS-1) FS-12 FS-28 FS-29 and Landfill 1 (LF-1)

One plume CS-19 is in long-term monitoring LF-2 and Storm Drain 5 (SD-5) two sites where the groundwater contamination no longer meets the definition of a plume are also in long-term monitoring

Treated water is returned to the aquifer using reinjection wells or infiltration galleries Treatment facilities at river systems utilize bubblers

Treatment plants clean up extracted contaminated groundwater by filtering it through carbon held in large vessels

Extraction wells are placed within a plume to pump contaminated groundwater from the aquifer to the treatment plant

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Since the early 1900s MMR has been used for military purposes including troop training and maneuvers military aircraft operations vehicle maintenance and support Some activities required the use of petroleum products solvents and other hazardous materials It was common practice for many years at the MMR as it was at other military bases and industrial facilities throughout the country to dispose of wastes in unlined landfills and drywells to dump and burn them at firefighter-training areas or to rinse them down drains In addition pipeline breaks and accidental spills occurred at MMR Today the use and disposal of hazardous materials is strictly managed and regulated at MMR to be protective of the environment The IRP is the program that cleans up soil and groundwater contamination resulting from historic use of the southern portion of MMR AFCEE is the agency that is responsible for the IRP EPA and MassDEP oversee AFCEErsquos cleanup effort at MMR

The US Army Environmental Commandrsquos Impact Area Groundwater Study Program (IAGWSP) is responsible for addressing soil and groundwater contamination from historic activities at Camp Edwards on the northern portion of MMR The phone number for the IAGWSP office is (508) 968-5630

How are the groundwater plumes treated

Aplume is a body of groundwater containing contaminants that exceed federal andor state safe drinking water standards When chemicals from source areas travel downward through the sandy soils they eventually reach the aquifer where they begin to dissolve Once dissolved they begin to move with the groundwater thus creating a plume

To actively treat groundwater contamination extraction wells are placed within a plume to pump the contaminated groundwater from the aquifer to a treatment plant where the water is filtered through carbon held in large vessels (The used carbon is recycled off site and reused at MMR) Treated water is returned to the aquifer using reinjection wells or infiltration galleries while treatment facilities at river systems utilize bubblers

The IRP is currently addressing 12 groundwater plumes Many of these plumes are located beyond the MMR boundary and are currently in various stages of study and cleanup At this time systems are treating approximately 14 million gallons of groundwater per day Computer modeling suggests that it may take more than 30 years to fully remediate all of the groundwater contamination associated with MMR Several plumes have shown dramatic decreases in size and contaminant concentrations due to years of groundwater treatment actions Plumes and treatment systems are continually being monitored and optimized to reduce the overall cleanup time

Eleven plumes are undergoing groundwater cleanup Ashumet Valley Chemical Spill 4 (CS-4) CS-10 CS-20 CS-21 CS-23 Fuel Spill 1 (FS-1) FS-12 FS-28 FS-29 and Landfill 1 (LF-1)

One plume CS-19 is in long-term monitoring LF-2 and Storm Drain 5 (SD-5) two sites where the groundwater contamination no longer meets the definition of a plume are also in long-term monitoring

Treated water is returned to the aquifer using reinjection wells or infiltration galleries Treatment facilities at river systems utilize bubblers

Treatment plants clean up extracted contaminated groundwater by filtering it through carbon held in large vessels

Extraction wells are placed within a plume to pump contaminated groundwater from the aquifer to the treatment plant

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

How are the groundwater plumes treated

Aplume is a body of groundwater containing contaminants that exceed federal andor state safe drinking water standards When chemicals from source areas travel downward through the sandy soils they eventually reach the aquifer where they begin to dissolve Once dissolved they begin to move with the groundwater thus creating a plume

To actively treat groundwater contamination extraction wells are placed within a plume to pump the contaminated groundwater from the aquifer to a treatment plant where the water is filtered through carbon held in large vessels (The used carbon is recycled off site and reused at MMR) Treated water is returned to the aquifer using reinjection wells or infiltration galleries while treatment facilities at river systems utilize bubblers

The IRP is currently addressing 12 groundwater plumes Many of these plumes are located beyond the MMR boundary and are currently in various stages of study and cleanup At this time systems are treating approximately 14 million gallons of groundwater per day Computer modeling suggests that it may take more than 30 years to fully remediate all of the groundwater contamination associated with MMR Several plumes have shown dramatic decreases in size and contaminant concentrations due to years of groundwater treatment actions Plumes and treatment systems are continually being monitored and optimized to reduce the overall cleanup time

Eleven plumes are undergoing groundwater cleanup Ashumet Valley Chemical Spill 4 (CS-4) CS-10 CS-20 CS-21 CS-23 Fuel Spill 1 (FS-1) FS-12 FS-28 FS-29 and Landfill 1 (LF-1)

One plume CS-19 is in long-term monitoring LF-2 and Storm Drain 5 (SD-5) two sites where the groundwater contamination no longer meets the definition of a plume are also in long-term monitoring

Treated water is returned to the aquifer using reinjection wells or infiltration galleries Treatment facilities at river systems utilize bubblers

Treatment plants clean up extracted contaminated groundwater by filtering it through carbon held in large vessels

Extraction wells are placed within a plume to pump contaminated groundwater from the aquifer to the treatment plant

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

CS-19 Groundwater Plume

The CS-19 site involves past ordnance and military waste disposal An area of approximately two acres was used to bury and detonate ordnance and munitions debris at depths to 12 feet These ordnance and waste disposal practices at the CS-19 site resulted in contaminants being released to the surrounding soil and groundwater AFCEE conducted multiple testing and cleanup actions at CS-19 between 2004 and 2009 including the removal of more than 2800 cubic yards of soil 8500 ordnance items and 27000 pounds of munitions debris from the original two-acre site

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

CS-10 Groundwater Plume

The Chemical Spill 10 (CS-10) groundwater plume resulted from spills and releases from multiple sources The primary source area originated from the former Boeing Michigan Aerospace Research Center Missile Site (from 1960 to 1973) and Unit Training Equipment Site (UTES) From 1996 through 2005 several source area cleanup actions were conducted at the site including 15 drainage structure removals and soil treatment with soil vapor extraction More than 1500 tons of contaminated soil were excavated and taken off site for disposal

Groundwater concentrations in monitoring wells located in the source area no longer exceed cleanup levels and the plume is detached from its primary source area Studies have shown that portions of the CS-10 plume no longer discharge to Ashumet and Johns Ponds Surface water sampling from both ponds in 2009 showed zero detections of contaminants associated with CS-10

The primary contaminants in the CS-10 plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL Long-term remediation is occurring with a treatment system comprised of a series of extraction wells treatment plants reinjection wells and infiltration galleries The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries and reinjection wells

An additional extraction well to address the southern trench contamination an additional reinjection well to improve hydraulic capture of the plume and revised flow rates in several extraction wells were completed in February 2009

The CS-10 Plume final ROD signed in 2009 specified continued operation and monitoring of the existing treatment system along with land use controls

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Ashumet Valley Groundwater Plume

The Ashumet Valley plume has two sources the former firefighter-training area 1 (FTA-1) and the former MMR Sewage Treatment Plant (CS-16 and CS-17) Firefighter-training exercises were held from 1958 to 1985 at FTA-1 during which time flammable waste liquids were burned and extinguished some of which entered the sandy soil and eventually reached the groundwater aquifer The former sewage treatment plant which operated from 1936 to 1995 released treated water to a series of sand infiltration beds Sludge materials were kept on site

Treatment of contaminated soils at FTA-1 was completed in September 1997 A total of 42531 tons of soil were treated at FTA-1 using a thermal treatment process In 2001 and 2002 contaminated soil was removed from the CS-16 and CS-17 sites and taken off base for proper disposal

The primary contaminants in the Ashumet Valley plume are the cleaning solvents PCE and TCE which have been detected above the state and federal MCLs of 5 microgL The Ashumet Valley plume is currently in long-term remediation Remediation is occurring with two treatment systems each comprised of a single extraction well treatment plant and infiltration galleries river discharge The treatment plants use granular activated carbon to remove the solvents from the groundwater and the treated water is returned to the aquifer through the infiltration galleries in the central portion of the plume and to a bog ditch along the Backus River in the southern area

The Ashumet Valley Plume final ROD which was signed in 2009 specified continued operation of the existing treatment system plus additional treatment for the southern portion of the plume The southern treatment system has been installed The ROD also required land use controls

AFCEE does not believe that any portion of the plume is currently discharging into Ashumet Pond Surface water sampling from Ashumet Pond in 2009 showed that no plume contaminants were detected

In 2001 AFCEE applied an alum treatment to Ashumet Pond water to reduce the amount of phosphorus in the pond much of which comes from the basersquos wastewater treatment plant phosphorus plume In 2004 a geochemical barrier (made up of zero-valent iron mixed with pond sediment) was installed along the shoreline of Ashumet Pond to reduce the amount of phosphorus in groundwater entering the pond A second alum treatment is being evaluated for 2010

A part of the southern portion of the Ashumet Valley plume discharges to the Backus River in Falmouth Surface water testing conducted in 2009 showed results below the MCL Please note that safe drinking water guidelines (MCLs) do not apply to surface water bodies AFCEE continues to monitor the entire plume area

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Employing energy conservation measures such as efficientbulllighting occupancy sensors and programmable thermostats in treatment plants and administrative buildings and recycling products such as paper tubing batteries and light bulbs to the maximum extent possible

Using biodiesel fuel and vegetable-based hydraulic oil to thebullmaximum extent possible in our diesel powered equipment

Employing low impact direct-push technology to collectbullgroundwater samples instead of using augersonic well drilling when viable AFCEE owns and operates a direct-push rig that is track mounted has a smaller footprint uses environmentally sensitive biofuels and is responsive Not only is this method of drilling more sustainable than other methods it is also less expensive since the work is done by site staff AFCEEMMR holds the record depth achieved by direct-push drilling technology - 319 feet below ground surface

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Information Booklet - April 2010

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

CS-23 and LF-1 Groundwater Plumes

The source of the Landfill 1 (LF-1) groundwater plume was the main MMR landfill which operated from 1941 to 1990 The LF-1 plume contains many COCs The more typical COCs are the solvents PCE TCE and CCl4 The state and federal MCLs for PCE TCE and CCI4 is 5 microgL

Test data indicate that no significant contamination is being released to groundwater from the older landfill cells at LF-1 and decreasing chemical concentrations in groundwater downgradient of the more recently used landfill cells suggest that the landfill cap there has been effective in reducing groundwater contamination at the source The cap is inspected annually to monitor its integrity

The LF-1 ROD signed in 2007 consists of continued long-term remediation with a groundwater extraction-and-treatment system and the implementation of land use controls The contaminated groundwater is treated at the LF-1 Treatment Plant and the Hunter Avenue Treatment Facility Water is returned to the aquifer through a reinjection well and infiltration trenches

Because a portion of the LF-1 plume discharges to both Red Brook and Squeteague Harbors surface water and discharging groundwater at the harbors are tested annually and results show that there are no ecological or human health risks

The CS-23 plume is a detached plume that has not been linked to a specific source area All of the potential source areas for the CS-23 plume have been investigated andor remediated The COCs in the CS-23 plume are TCE and CCl4

The CS-23 ROD signed in 2007 consists of continued remediation and operation of the existing groundwater cleanup system and land use controls The contaminated water is treated at the Hunter Avenue Treatment Facility Water is returned to the aquifer through infiltration trenches

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

FS-1 and FS-12 Groundwater Plumes The source of the Fuel Spill 1 (FS-1) groundwater plume is the Aviation Gas Fuel Valve Test Dump Site in the eastern part of the base The site was used from 1955 to 1970 to test fuel dump valves on EC-121 Super Constellation aircraft which involved the release of fuel directly onto the ground Currently no significant levels of COCs are present in the surface or subsurface soils at the FS-1 source area and the source area groundwater is sampled for lead only

The FS-1 groundwater plume contains the fuel additive ethylene dibromide (EDB) at levels above the MMCL which is 002 microgL The FS-1 plume is currently in long-term remediation with a groundwater extraction-and-treatment system in the Quashnet River cranberry bog area just northeast of Johns Pond The system was designed to prevent upwelling of EDB contamination into the Quashnet River and associated cranberry bogs The treatment plant uses granular activated carbon to remove EDB from the groundwater which is then discharged to the Quashnet River through a series of oxygenating bubblers The latest test results showed that the FS-1 treatment system has been successful in reducing both the amount of EDB in the FS-1 plume and the EDB concentrations in the surface water of the Quashnet River and associated bogs A 2000 ROD specifies active treatment of the plume along with monitoring

The source of the FS-12 groundwater plume was an estimated 70000-gallon release from a section of a now-abandoned fuel pipeline that ran from the Cape Cod Canal to MMR EDB is the only remaining contaminant above cleanup standards in the FS-12 groundwater plume The source area groundwater is currently being monitored after having undergone subsurface remediation in the 1990s Groundwater sampling indicates that the source area has been successfully remediated The pipeline has been cleaned and closed with state and federal regulatory approval

The FS-12 plume is currently in long-term remediation with a groundwater extraction-and-treatment system The treatment system consists of extraction wells a treatment plant and reinjection wells The 2006 ROD called for the status quo of operating and monitoring the existing system The latest test results indicate that the extraction wells continue to successfully contain the FS-12 groundwater plume and the size of the plume has been reduced significantly Land use controls are in place for the FS-1 and FS-12 plumes

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Recycling granular activated carbon which is used in thebulltreatment systems to remove the contaminants from the groundwater through a process called reactivation Our used carbon is removed from the vessels reactivated off site and returned to MMR for reuse

Providing treated water for beneficial reuse such as irrigatingbullthe Veterans Affairs cemetery and as a geothermal source for heating ventilating and air conditioning systems

Pilot-testing new technologies such as ozone and hydrogenbulltreatment of plant influent water to determine if they can be used effectively to pretreat the water and extend the life of the carbon beds andor reduce operating costs

Evaluating various types of carbon to determine if a morebullefficient product is available

Employing energy conservation measures such as efficientbulllighting occupancy sensors and programmable thermostats in treatment plants and administrative buildings and recycling products such as paper tubing batteries and light bulbs to the maximum extent possible

Using biodiesel fuel and vegetable-based hydraulic oil to thebullmaximum extent possible in our diesel powered equipment

Employing low impact direct-push technology to collectbullgroundwater samples instead of using augersonic well drilling when viable AFCEE owns and operates a direct-push rig that is track mounted has a smaller footprint uses environmentally sensitive biofuels and is responsive Not only is this method of drilling more sustainable than other methods it is also less expensive since the work is done by site staff AFCEEMMR holds the record depth achieved by direct-push drilling technology - 319 feet below ground surface

Optimizing power purchase agreements for additional costbullsavings purchasing green energy and participating in the New England energy demand response program

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

CS-4 CS-20 CS-21 FS-28 and FS-29 Groundwater Plumes

Five groundwater plumes can be found in the area north and south of Route 151 in the town of Falmouth They are FS-28 FS-29 CS-4 CS-20 and CS-21 Only CS-4 has a known source area a former vehicle maintenance area and storage yard on the MMR The other plumes were found to be disconnected from distinct source areas They most likely originated somewhere in the southern portion of MMR which contained various aircraft and vehicle maintenance shops runways and housingpersonnel support facilities Records indicate that spills andor releases occurred in these areas in the past COCs in the plumes are fuel and solvent-related contaminants They include EDB PCE TCE and CCl4 The MMCL for EDB is 002 microgL while the MCL for the rest of the contaminants is 5 microgL

More than 18000 tons of contaminated soil were treated on site at the CS-4 source area and additional soil was transported off site for proper disposal A groundwater extraction-and-treatment system began operating in 1993 but was later replaced by a more efficient system in 2006 to better capture the plume

Portions of the FS-28 plume were first discovered in 1993 beneath the leading edge of the CS-4 plume In 1996 groundwater investigations found EDB upwelling into the Coonamessett River in Falmouth No EDB is presently detected in the Coonamessett River The FS-28 plume is currently in long-term remediation with a groundwater extraction-and-treatment system A treatment plant is located in a bog area just south of Hatchville Road and treated water is discharged to the Coonamessett River through two oxygenating bubblers Shallow wellpoint extraction wells operated for several years but are no longer being used In 2007 a new extraction well was installed to the south to address a deep lobe of EDB

The FS-28 plume underflows Coonamessett Pond and has not affected the pond or a nearby Town of Falmouth municipal well In 2002 AFCEE funded a $52 million wellhead treatment system to ensure a safe water supply for the Falmouth well A ROD was issued in October 2000

The FS-29 CS-20 and CS-21 groundwater plumes were discovered in the late 1990s A ROD for FS-29 was issued in October 2000 and a ROD for CS-4 CS-20 and CS-21 was issued in February 2000 Since 2006 the FS-29 CS-4 CS-20 and CS-21 groundwater plumes have been undergoing active treatment through a series of extraction wells reinjection wells and infiltration trenches Extracted plume water is treated with granular activated carbon at the Hunter Avenue Treatment Facility on base Land use controls are in place for all these plumes

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Pilot-testing new technologies such as ozone and hydrogenbulltreatment of plant influent water to determine if they can be used effectively to pretreat the water and extend the life of the carbon beds andor reduce operating costs

Evaluating various types of carbon to determine if a morebullefficient product is available

Employing energy conservation measures such as efficientbulllighting occupancy sensors and programmable thermostats in treatment plants and administrative buildings and recycling products such as paper tubing batteries and light bulbs to the maximum extent possible

Using biodiesel fuel and vegetable-based hydraulic oil to thebullmaximum extent possible in our diesel powered equipment

Employing low impact direct-push technology to collectbullgroundwater samples instead of using augersonic well drilling when viable AFCEE owns and operates a direct-push rig that is track mounted has a smaller footprint uses environmentally sensitive biofuels and is responsive Not only is this method of drilling more sustainable than other methods it is also less expensive since the work is done by site staff AFCEEMMR holds the record depth achieved by direct-push drilling technology - 319 feet below ground surface

Optimizing power purchase agreements for additional costbullsavings purchasing green energy and participating in the New England energy demand response program

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

Progress Over The Years

Much progress has been made over the last 15 years Program-wide the source areas have been cleaned up and 11 groundwater plumes are undergoing pump-and-treat cleanup action both on and off base All environmental cleanup decisions and remedies are in place In the future the program will continue to monitor adjust and shut down treatment systems as cleanup progress is made The Air Force will continue to conduct the most efficient cleanup operations while ensuring the protection of public health and the environment

The SD-5 plume depiction illustrates the transformation of the plume over time due to the effect of cleanup systems used by the Air Force for several years Contaminated water was cleaned by using two technologies The first involved extracting the plume water pumping it to a treatment building where large vessels of granular activated carbon removed the solvent contamination and then the clean water was returned to the ground through reinjection wells Two recirculation wells were also used Those involved two underground standalone treatment systems within the neighboring community That technology used air and pumps to remove the solvents from the plume and capture them in carbon tanks The plume has now been cleaned up to the point where only residual traces of solvent contamination are found in monitoring wells which are periodically tested

The following pages depict the cleanup progress of several IRP groundwater plumes over time Most plumes show a significant reduction in size and contaminant mass A few show a larger area which is related to plume information uncertainties in the early part of the cleanup program and changing conditions over time a significant reason why diligent monitoring is required For more information and depictions of all AFCEE groundwater plumes progress over time go to httpwwwmmrorgCleanupplumes_fshtm

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

Recycling granular activated carbon which is used in thebulltreatment systems to remove the contaminants from the groundwater through a process called reactivation Our used carbon is removed from the vessels reactivated off site and returned to MMR for reuse

Providing treated water for beneficial reuse such as irrigatingbullthe Veterans Affairs cemetery and as a geothermal source for heating ventilating and air conditioning systems

Pilot-testing new technologies such as ozone and hydrogenbulltreatment of plant influent water to determine if they can be used effectively to pretreat the water and extend the life of the carbon beds andor reduce operating costs

Evaluating various types of carbon to determine if a morebullefficient product is available

Employing energy conservation measures such as efficientbulllighting occupancy sensors and programmable thermostats in treatment plants and administrative buildings and recycling products such as paper tubing batteries and light bulbs to the maximum extent possible

Using biodiesel fuel and vegetable-based hydraulic oil to thebullmaximum extent possible in our diesel powered equipment

Employing low impact direct-push technology to collectbullgroundwater samples instead of using augersonic well drilling when viable AFCEE owns and operates a direct-push rig that is track mounted has a smaller footprint uses environmentally sensitive biofuels and is responsive Not only is this method of drilling more sustainable than other methods it is also less expensive since the work is done by site staff AFCEEMMR holds the record depth achieved by direct-push drilling technology - 319 feet below ground surface

Optimizing power purchase agreements for additional costbullsavings purchasing green energy and participating in the New England energy demand response program

Accounting for costs efficiency and environmental impactbullof our program decisions These activities are tracked and reported in quarterly optimization reports These reports are available on the wwwmmrorg website

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years

AFCEErsquos aggressive optimization activities have resulted in a more sustainable remediation program at MMR Our ldquobetter cheaper fasterrdquo approach is intended to expedite aquifer restoration and cleanup timeframes while reducing costs to the taxpayers and minimizing our carbon footprint Optimization activities conducted by AFCEE at MMR include

Demonstrating alternative in situ technologies such as a passive zero-valent iron barrier This barrier requiresbullno OampM and was installed along the Ashumet Pond shoreline to help reduce phosphorus discharging into the surface water

Continuously adjusting groundwater remediation systems as the groundwater plumes change over time Forbullexample extraction wells are taken out of operation once the portion of the aquifer is cleaned up In some cases extraction wells are added if deemed necessary to expedite aquifer restoration and eliminate risks to human health and the environment In other cases flow rates at extraction wells are modified as needed andor systems are pulse-pumped and packers are installed in extraction wells to focus extraction stress on changing contaminant distribution In one case a reinjection well was converted to an extraction well when contamination was detected unexpectedly in monitoring wells outside of the delineated plume area

Installing variable frequency drives (VFDs) on extraction well pumpbullmotors to save energy and reduce wear and tear on pumpmotor assemblies In the absence of VFDs extraction well pumps and motors are changed out by our well maintenance staff to appropriately size the pumps and motors to optimized flow rates at extraction wells resulting in a reduction in unnecessary energy use In addition energy saving premium efficiency motors have been installed on booster and transfer pumps in treatment plants

Adjusting the number of monitoring locations frequency of samplingbulland analytes in the monitoring program as the remediation requirements are refined Passive sampling techniques such as passive diffusion bags and Hydrasleevesreg are used to the maximum extent possible to save time reduce costs and reduce impacts to the environment as compared to conventional pumped sampling

A major optimization effort completed last year was the installation of renewable energy in the form of a 15 MW Fuhrlaender wind turbine The wind turbine started operating on December 2 2009 and is expected to reduce AFCEErsquos annual $2 million electric cost by 25 to 30 The wind turbine is also anticipated to offset air emissions generated indirectly through the use of electricity from fossil fuel based power plants by approximately 25 to 30 Based on a range of utility cost projections and an estimate of the turbinersquos energy production the $46 million wind turbine is anticipated to have a payback period between six and eight years
