EXECUTIVE SUMMARY

ISI Report – Ferriter Oil Company – Randolph, VT page i

Ross Environmental Associates, Inc. 31168ISI

Ross Environmental Associates, Inc. (R.E.A.) has conducted an Initial Site Investigation (ISI) at the

Ferriter Oil bulk petroleum storage facility located on 6 Hull Street in Randolph, Vermont. Field

investigation included: installation of thirteen soil borings with the installation of six monitoring wells,

sampling and analysis of groundwater from four newly installed monitoring wells and one existing

monitoring well, and a receptor survey to identify potential risks to the environment and human health.

Soil and groundwater beneath the site have been impacted by operations at the Ferriter Oil Company bulk

petroleum storage facility; however, available information indicates that the contamination is characteristic of

weathered petroleum. The Vermont soil screening action level for petroleum contaminated soil was

exceeded in shallow soil and subsurface soil samples collected during the soil boring program. The Vermont

groundwater enforcement standard, for naphthalene was exceeded in the groundwater sample collected from

MW-2, which is centrally located on the property between the active and inactive above ground storage tanks

(ASTs). Available information indicates that the extent of subsurface contamination has been adequately

defined and that residual petroleum contamination is concentrated in the areas of the ASTs and loading

stations.

On the basis of the results of this investigation, R.E.A. makes the following recommendations:

1. Due to the presence of low concentrations of volatile petroleum compounds and TPH in

groundwater beneath the site, a groundwater sampling event should be completed in December

2011 to confirm the previous findings. Samples should be analyzed for the possible presence of

VOCs and TPH in accordance with EPA methods 8260 and 8015DRO (diesel range organics).

2. The areas of visibly stained surface soil should be addressed to prevent possible exposure via

direct contact. At a minimum, the visibly stained surface soil should be managed in accordance

with applicable State guidelines, specifically the “Agency Guidelines for Petroleum Contaminated Soil and

Debris” dated August 1996.

3. A soil management plan should be prepared which documents the procedures to be followed

during the construction of the proposed secondary containment system and/or redevelopment of

the property. The soil management plan should also include the area of visibly stained surface

soil noted in the vicinity of the active ASTs.

4. The operator of the Randolph Village water system (WSID #5179) should be notified of the

findings of this investigation and presence of residual petroleum contamination discovered on the

Ferriter Oil Company property.

5. A summary report should be completed following the next phase of site characterization, which

should include recommendations for possible remediation, long term monitoring, or site closure.

1.0 INTRODUCTION

On 1 July 2011, Mr. Jim Townsend of Ferriter Oil Company retained the services of Ross Environmental

Associates, Inc. (R.E.A.) to complete an Initial Site Investigation (ISI) at the bulk petroleum storage facility

located on Hull Street in Randolph, Vermont. The investigation was performed to address the findings of the

site assessment completed in September 2011, which identified the presence of petroleum contamination in

soil above state guidelines. The ISI was performed in accordance with the work plan dated 22 September

2011, which was approved by the Vermont Department of Environmental Conservation (VT DEC) in an

email dated 23 September 2011.

This report has been prepared by R.E.A. under the direction of Mr. Jim Townsend and the VT DEC,

unauthorized use or reproduction of this report is prohibited without written authorization from R.E.A., or

Mr. Townsend.

1.1 Site Location and Setting

The subject property, Ferriter Oil Company, is located at 6 Hull Street approximately one-half mile east

of downtown Randolph, Vermont (Figure 1). The property encompasses approximately 1.0 acres on

the northern side of Hull Street. The facility is occupied by three active and two inactive above ground

storage tanks (ASTs), associated piping and two loading stations. According to Mr. Jim Townsend the

inactive ASTs were temporarily taken out-of-service in the spring. The southern portion of the property

and the areas immediately adjacent to the ASTs are open land, while the northern portion of the property

is primarily wooded. One active tank contains heating oil (UST # 8 – 17,000 gallons), another services

kerosene (UST # 7 – 10,000 gallons), while the third tank is used for storing off-road diesel fuel (UST #

6 – 10,000 gallons). All three active tanks are located on the southwestern corner of the property within

20 feet of Hull Street. The active loading area is located between Hull Street and the active ASTs. The

two inactive tanks are located along the northern property boundary, which borders the Montague Golf

Course. The inactive loading area is located on the southern side of the inactive ASTs. A partial

earthen-berm is located around three sides of the inactive ASTs. An aerial photograph showing the site

and surrounding properties is included as Figure 2.

The ground surface in the vicinity of the ASTs is relatively flat with a slight slope toward a wooded area

located to the north. The ground surface in the vicinity of the former ASTs has an approximate

elevation of 660 feet above mean sea level, (USGS: Randolph, Vermont Quadrangle 1981). The nearest

surface water body is the Third River located approximately 1,200 feet to the east. An unnamed tributary

to the Third River is located approximately 2,200 feet to the south. The geographic coordinates of the

site are: latitude 43° 55’ 13.33” North, and longitude 72° 39’ 26.17” West.



The surficial geology of the area is mapped as pebbly sand with silt, silty clay, and clay located to the east

(Stewart and MacClintock, 1970). Bedrock underlying the site is classified as the Waits Rive formation,

which consists of gray quartzose and micaceous crystalline limestone of Lower Devonian age (Doll,

1961). No bedrock outcrops were observed on the site or adjacent properties, and bedrock was not

encountered during soil boring activities. The surficial soil in the vicinity of the site is mapped as

Merrimac fine sandy loam with 0 to 3 percent slopes by the U.S. Department of Agriculture.

1.2 Site History

On 16 September 2011, Ross Environmental Associates, Inc. (R.E.A.) was contact by Mr. Jim

Townsend of Ferriter Oil Company, regarding a possible sale of the property and questions about the

U.S. EPA Spill Prevention Control and Countermeasure (SPCC) rules and regulations. At that time, Mr.

Townsend provided R.E.A. with a tour of the property and brief overview of the site operations. The

ASTs were found to be in very good condition, but some visibly stained soil was present in the vicinity of

the active loading area. According to Mr. Townsend the facility has been in operation for over 40 years

and was previously owned by Tom Ferriter. Mr. Townsend has owned the property since 1988 and has

never had a reportable spill, which was confirmed based on review of the Vermont Agency of Natural

Resources (ANR) on-line spill database.

On 21 September 2011, R.E.A. personnel returned to the site to collect soil samples in areas of visible

staining and in areas of the property where product transfers routinely occurred. Soil samples were

screened for the possible presence of VOCs with a photo-ionization detector (PID). Elevated PID

readings were obtained on soil samples collected on-site ranging from 0.2 to 109 parts per million-

volume (ppmv), which are above the VT DEC action level of 10 ppmv for fuel oil/diesel contaminated

soil. The highest PID readings (46 to 109 ppmv) were obtained in the area of visibly stained soil adjacent

to the active loading station. Based on the presence of PID readings detected above the VT DEC action

level, R.E.A. recommended that Mr. Townsend report the findings to the VT DEC.

On 23 September 2011, the VT DEC approved the work plan and cost estimate to perform an ISI at the

Ferriter Oil Company property in Randolph, Vermont.

1.3 Land Use and Adjacent Property Ownership

The subject property is located on Hull Street approximately one-half mile east of downtown Randolph,

Vermont. The area is a mixed industrial/residential area serviced by municipal sewer and water. Hull

Street abuts the property to the south-southwest and the property to the north and east is occupied by

the Montague Golf Course. One private residence is located on the adjacent property to the northwest,

which is separated from the Ferriter Oil Company property by a wooded area.



An aerial photograph showing adjacent property site features and sensitive receptors is included as

Figure 3.

2.0 FIELD INVESTIGATION RESULTS AND PROCEDURES

R.E.A.’s field investigation included the completion of thirteen soil borings with the subsequent installation

of six monitoring wells (MW-2, MW-3, MW-4, MW-5, MW-6, and MW-7), field screening of subsurface soil

samples for the possible presence of volatile organic compounds (VOCs) using a portable photo-ionization

detector (PID), collection and analysis of groundwater samples from one existing monitoring well and three

of the newly installed monitoring wells, a site survey to obtain relative groundwater elevations to calculate

groundwater flow, and a receptor survey to identify potential risks to the environment and human health.

Monitoring well locations and significant site features are shown on Figure 4. Photographs taken during the

soil boring program are included in Appendix A.

The objectives of this initial site investigation were to complete the following.

� Evaluate the degree, extent, and type of contamination present in soils and groundwater;

� Identify potential sources and types of onsite contamination;

� Qualitatively assess the risks to environmental and public health via relevant sensitive receptors

and potential contaminant migration pathways;

� Identify the need for further site characterization, appropriate monitoring, and/or remedial actions

based on the site conditions.

2.1 Contaminants of Concern

Based on available information, the contaminants of concern (COC) at Ferriter Oil Company appear to

be related to the petroleum products stored in the ASTs. Low concentrations 1,3,5-trimethlybenzene,

1,2,4-trimethlybenzene and naphthalene as well as several other volatile petroleum compounds and diesel

range organics were detected in groundwater beneath the site. All of these compounds are typically

associated with petroleum products such as kerosene, fuel oil, and off-road diesel. A summary of various

regulatory standards and chemical properties for these compounds is included on Table 1.

2.2 Source Area Evaluation

According to Mr. Jim Townsend, Ferriter Oil Company has operated a bulk petroleum storage facility on

the property for over 40 years. Residual petroleum contamination discovered on site is likely related to

the long history of petroleum storage on the property. In general, surface soil contamination appears to

be limited to the area adjacent to the active loading station, but subsurface contamination appears to be

located adjacent to both the active and inactive ASTs. This contaminant distribution is consistent with



the reported site use and history of the property. At this time, the extent of contamination present on

the subject property appears to have been adequately defined. No potential upgradient sources of

contamination were identified during review of available information and VT ANR databases.

2.3 Soil Boring and Monitoring Well Installation

On 13 and 14 October 2011, R.E.A. provided oversight during the installation of thirteen soil borings

with the subsequent installation of six monitoring wells. Monitoring wells were installed at locations

based on field observations with spatial distribution upgradient and downgradient of the former ASTs

and fuel handling areas. Approximate soil boring and monitoring well locations are shown on Figure 4.

� MW-1 is an existing well that was installed to the northeast of the active ASTs.

� MW-2 (SB-1) was installed in the central portion of the property between the active and inactive

ASTs.

� MW-3 (SB-4) was installed adjacent to the inactive ASTs approximately 15 feet from the eastern

property boundary.

� MW-4 (SB-5) was installed along the southern property boundary.

� MW-5 (SB-7) was installed approximately six feet east of AST # 8 and five feet north of AST

#6.

� MW-6 (SB-8) was installed approximately 10 feet east of AST #7.

� MW-7 was installed in the vicinity of the loading area where visible surface soil staining was

noted.

� SB-2 and SB-3 were installed within the earthen-berm adjacent to the inactive ASTS.

� SB-6 was installed on the northern side of the active tanks along the tree line.

� SB-9, SB-10, SB-11 and SB-12 were installed in front of the active ASTs along Hull Street, which

is also the area of the active fuel loading station.

During the soil boring program, subsurface soil at the site was predominantly characterized as medium to

fine sand with varying amounts of gravel above the water table, which graded to fine sand and silt below

the water table. The observed soil conditions were consistent with published reports, which listed the

surficial geology as pebbly sand with silt, silty clay, and clay. Groundwater was encountered between 10

and 14 feet bgs at the time of drilling. Soil borings were advanced to approximately 10 to 22 feet bgs

based on subsurface conditions and depth to groundwater.

Petroleum odors were noted on subsurface soil samples collected from the soil borings completed

adjacent to both loading area, which corresponded with the locations of elevated PID readings. The

highest PID readings (40 to 230 ppmv) were generally obtained on soil samples collected from the soil



borings completed adjacent to the loading areas and in the central portion of the property. PID

readings obtained on the soil samples collected from the soil borings collected on the western corner of

the property and downgradient of the inactive ASTs were generally 0.4 ppmv or less. PID screening

results are included on the soil boring/monitoring well construction logs in Appendix B.

Each monitoring well was constructed using a 2.0-inch-diameter schedule 40 polyvinyl chloride (PVC)

with flush threaded joints and 0.01-inch factory-slotted well screens. Ten-foot well screens were used

for MW-2, MW-6 and MW-7. MW-4 and MW-5 were installed with an eight-foot well screen. A fifteen-

foot well screen was used for MW-3 based on field observations. Solid PVC risers, extending from the

top of the well screen to ground surface were used to complete each well. A clean sand pack was placed

around the screened section of each monitoring well extending one to two feet above the top of the

screen and a bentonite seal was placed above the sand pack. Flush-mounted road-box protective casings

were installed over each monitoring well. Each well was developed after installation by removing eight to

ten standing volumes of water using a peristaltic pump. Soil descriptions and monitoring well

construction details are included on the soil boring logs in Appendix B. Technical Drilling Services, Inc.

of Sterling, Massachusetts installed the soil borings and monitoring wells with a hollow stem auger under

direct supervision of R.E.A. personnel.

R.E.A.’s Field Scientist screened soil samples from each soil boring for the possible presence of volatile

organic compounds (VOCs) using a PhotoVac PE 2020 portable PID or Ion-science Pho-check Tiger.

The PID was calibrated with an isobutylene standard gas to a benzene reference on the day of drilling.

After installation of the soil boring/monitoring wells, R.E.A. surveyed the locations of the borings/wells

in relation to existing site features. Each boring/well was located in azimuth to an accuracy of ± 1.0 foot,

and in elevation with an accuracy of ± 0.01 feet relative to an on-site benchmark of 100.00 feet.

2.4 Groundwater Elevations and Flow Direction

On 19 October 2011, groundwater flow in the unconfined surficial aquifer at the site was primarily

toward the east with an estimated hydraulic gradient of approximately 19 percent (between MW-1 and

MW-2). However, the depths to groundwater measurements were erratic ranging from 4.9 to greater

than 19.25 feet below ground surface (bgs). This data suggests that there may be an old corridor passing

through the central portion of the property, perhaps an old river bed or utility corridor that may be

influencing groundwater flow and contaminant migration on the property. Also, the two most

downgradient monitoring wells (MW-3 and MW-4) were both dry even though these two wells were

installed to the same or greater depths as were all of the other wells. Water level measurements and



elevation calculations for 19 October 2011 are presented in Table 2 and the groundwater contour map

prepared using this data is presented as Figure 5.

Static water-table elevations were computed for each monitoring well by subtracting measured depth-to-

water readings from the surveyed top-of-casing (TOC) elevations, which are relative to an arbitrary site

datum of 100.00 feet. Depth to groundwater during the sampling event (19 October 2011) ranged from

4.9 to greater than 19.25 feet bgs. Groundwater was observed in soil borings at the time of drilling on 13

October 2011 at depths ranging from 6.5 to 15 feet bgs.

The effective porosity of the predominantly sand and gravel material encountered below the water-table

is presumably around 0.3, with hydraulic conductivities of 0.28 to 2.8 feet per day (Freeze & Cherry,

1979). Assuming Darcian flow, these estimates combine with the calculated horizontal gradient ranging

from 19 percent yield an estimated range of ground-water flow velocities of between 0.18 to 1.77 feet per

day. Contaminant migration would be less accounting for retardation and dispersion of the

contaminants.

2.5 Groundwater Sampling and Analysis

Groundwater beneath the site has been impacted by contamination characteristic of weathered

petroleum. Low concentrations of volatile petroleum compounds were detected in the samples collected

from MW-2, MW-6 and MW-7; however, the only Vermont Groundwater Enforcement Standard

(VGES1) that was exceeded was for naphthalene which was detected in the sample collected from MW-2

at 292 micrograms per liter (ug/L). No other VGESs were exceeded in any of the other samples

collected on 19 October 2011. The highest concentrations of petroleum contamination were detected in

the sample collected from MW-2, which is located centrally between the active and inactive ASTs.

Naphthalene, 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene, 4-isopropyl toluene, and n-butyl benzene

were detected in the samples collected from MW-2, MW-6, and MW-7 at concentrations between 1.2 and

292 micrograms per liter (µg/L). Low concentrations of ethylbenzene, total xylenes, n-propylbenzene,

isopropyl benzene, and sec-butyl benzene were also detected in the MW-2 sample and low

concentrations of n-propylbenzene, and sec-butyl benzene were detected in the MW-6 sample. No

volatile petroleum compounds were detected above the laboratory detection limits in the sample

collected from MW-1. TPH was detected in the samples collected from MW-2, MW-6, and MW-7 at

5.07, 2.31, 3.1 and 5.01 milligrams per liter (mg/L), respectively. TPH was not detected in the sample

1The Vermont DEC has established groundwater enforcement standards for eight petroleum related VOCs, as follows: benzene - 5 ug/L; toluene - 1,000 ug/L; ethylbenzene - 700 ug/L; xylenes - 10,000 ug/L; MTBE - 40 ug/L; naphthalene – 20 ug/L; and 1,3,5-trimethyl benzene, & 1,2,4-trimethyl benzene – 350 ug/L (combined).



collected from MW-1. It should be noted that the VT DEC does not currently have an enforcement

standard or guideline for TPH concentrations in groundwater.

No petroleum compounds were detected in the trip-blank sample and the analytical results for the blind

field duplicate sample (MW-6) were generally within the acceptable EPA criteria. The analytical results

are summarized on Table 3, and a copy of the groundwater laboratory analytical report is included as

Appendix D. Contaminant distribution, based on samples collected on 19 October 2011, is shown on

Figure 6.

Prior to sample collection, R.E.A field personnel measured the water level in each monitoring well and

purged approximately three to five standing volumes of water from each well. All of the groundwater

samples were collected using dedicated polyethylene tubing. Groundwater was pumped directly into

unpreserved one-liter amber jars and 40-milliliter glass vials with Teflon-lined septum lids. Each 40-

millilter VOC sample vial was preserved with hydrochloric acid to reduce the pH to less than 2 standard

units. Immediately after sample collection, field measurements were obtained for pH, specific

conductivity, temperature, total dissolved solids (TDS), and oxygen reduction potential (ORP). A

summary of the field measurement data is included on Table 4.

On 19 October 2011, groundwater samples were collected from four on-site monitoring wells (MW-1,

MW-2, MW-6, and MW-7). No samples were collected from MW-3, MW-4 or MW-5, which were dry at

the time of the sampling event. Groundwater samples were analyzed for the possible presence of volatile

organic compounds and total petroleum hydrocarbons (TPH) in accordance with U.S. EPA Methods

8260 and 8015DRO (diesel range organics), respectively. All samples were transported under chain-of-

custody in an ice-filled cooler to AMRO Environmental Laboratories of Merrimack, New Hampshire for

laboratory analysis.

for Testing and Materials.

3.0 SENSITIVE RECEPTOR IDENTIFICATION AND RISK ASSESSMENT

Based on available information, surface soil, subsurface soil, and groundwater in the vicinity of the former

ASTs have been impacted by petroleum contamination; however, only the VGES for naphthalene was

exceeded in groundwater beneath the site. The Vermont soil screening action level for petroleum

contaminated soil was exceeded in soil samples collected during the initial assessment and soil boring

program. No other sensitive receptors in the vicinity of the site appear to be impacted at this time. The

approximate locations of nearby sensitive receptors are shown on Figure 3.

3.1 Receptor Identification

Sensitive receptors identified in the vicinity of the subject property are summarized below:

� Soil and groundwater within the general vicinity of the AST system.

� A portion of Zone 3 of the source protection area (SPA) for the Randolph Village public

community drinking water system (WSID # 3179) extends beneath the western portion of the


� The supply well serving the Randolph Village public community drinking water system (WSID #

3179) located approximately 800 feet to west.

� The Third River located approximately 1,200 feet to the east.

� An unnamed tributary to the Third River located approximately 2,200 feet to the south.

� Several Class 2 wetlands located within 0.5-miles of the subject property.

� Several off-site drinking water wells located within 0.5-miles of the subject property including the

public community water system serving the Three Stallion Inn.

3.2 Risk Assessment

On the basis of the information obtained during this investigation, R.E.A. has qualitatively assessed the

risks that the subsurface contamination poses to human health and the environment. The findings are

summarized as follows:



� The presence of visibly stained surface soil on site presents a potential exposure risk via direct

contact. Although the area is not likely to be frequented by pedestrians, access to the site is

currently unrestricted. The primary concern with exposure to petroleum contaminated soil is

associated with possible worker exposure during redevelopment of the property. The presence

of surface soil contamination also presents an on-going threat to the underlying groundwater

formation and possibility of off-site migration via overland runoff.

� Subsurface soil beneath the site has been impacted by petroleum contamination, which is

currently an on-going threat to the underlying groundwater formation. Elevated PID readings

were noted on subsurface soil samples collected during the soil boring program.

� Groundwater beneath the site has been impacted by volatile petroleum compounds

characteristic of weathered petroleum. Low concentrations of VOCs and TPH were detected in

the three monitoring wells that were sampled on 19 October 2011. Available information

suggests that the extent of groundwater contamination has been adequately defined and that

contamination does not appear to be migrating off site at this time.

� The supply well and SPA for the Randolph Village water system are situated upgradient of the

Ferriter oil company property and are not likely to be impacted by residual contamination

discovered onsite. Although the threat to this sensitive receptor is considered low, this public

drinking water supply is threatened by the presence of residual petroleum contamination, due to

the close proximity to the site and importance of this resource.

� The surface water bodies located in close proximity to the site including the Third River and

several Class 2 wetlands are not likely to be impacted by residual petroleum contamination

discovered on the Ferriter Oil Company property and the threat to these surface water bodies is

considered to be very low.

� Several off-site private supply wells are located within 0.5 miles of the Ferriter Oil Company

property; however, a majority of the adjacent properties are supplied with drinking water from

the municipal water. Based on available information, the threat to off-site drinking water supply

wells is considered low.

4.0 DATA EVALUATION AND CONCEPTUAL MODEL

Soil and groundwater beneath the site have been impacted by operations at the Ferriter Oil Company bulk

petroleum storage facility; however, available information indicates that the contamination is characteristic of

weathered petroleum. The Vermont soil screening action level for petroleum contaminated soil was

exceeded in shallow soil and subsurface soil samples collected during the soil boring program and the

Vermont groundwater enforcement standard (VGES) for naphthalene was exceeded in the groundwater



sample collected from one monitoring well. Available information indicates that residual subsurface soil

contamination is concentrated in the areas of the above ground storage tanks (ASTs) and road side loading

station.

Generally, the VT DEC requires active remediation when greater than 1/8” of free-product is present, or

when human health or a sensitive receptor is impacted or threatened by contamination. Based on available

information, further active remediation is not likely to be required by the VT DEC at this time. However,

additional groundwater and sensitive receptor monitoring may be required. In addition, during AST

decommissioning and/or construction of the proposed secondary containment system, petroleum

contaminated soil (PCS) will need to be managed in accordance with State and federal guidelines.

A summary of the significant findings of the ISI is outlined below:

� The VGES for naphthalene was exceeded in the groundwater sample collected from MW-2; no

other VGESs were exceeded in any of the other groundwater samples collected on 19 October 2011.

� Naphthalene, 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene, 4-isopropyl toluene, and n-butyl

benzene were detected in the samples collected from MW-2, MW-6, and MW-7 at concentrations

between 1.2 and 292 µg/L. Low concentrations of ethylbenzene, total xylenes, n-propylbenzene,

isopropyl benzene, and sec-butyl benzene were also detected in the MW-2 sample and low

concentrations of n-propylbenzene and sec-butyl benzene were detected in the MW-6 sample. No

volatile petroleum compounds were detected above the laboratory detection limits in the sample

collected from MW-1.

� TPH was detected in the samples collected from MW-2, MW-6, and MW-7 at concentrations of

5.07, 2.31, 3.1, and 5.01 mg/L, respectively. TPH was not detected in the sample collected from

MW-1.

� The two most downgradient wells (MW-3 and MW-4) were dry at the time of the groundwater

sampling event; therefore, no groundwater samples were collected for laboratory analysis. The well

screens for these monitoring wells are located at the same depths or deeper than the other on-site

monitoring wells, which suggest the area may have been filled in with non native material. At the

time of drilling the depth to groundwater was noted at 8 and 15 feet bgs.

� Petroleum odors were noted on subsurface soil samples collected from the soil borings completed

adjacent to both loading area, which corresponded with the locations of elevated PID readings. The

highest PID readings (40 to 230 ppmv) were generally obtained on soil samples collected from the

soil borings completed adjacent to the loading areas and in the central portion of the property. PID

readings obtained on the soil samples collected from the soil borings collected on the western corner

of the property and downgradient of the inactive ASTs were generally 0.4 ppmv or less.



� Subsurface soils at the site consisted predominantly of fine sand with varying amounts of gravel

within the upper four to eight feet which grade to fine sand and silt below the water table.

� Groundwater flow in the unconfined surficial aquifer at the site was primarily toward the east with a

hydraulic gradient of approximately 19 percent. This groundwater flow is generally toward the Third

River and away from the area of the Randolph Village source protection area and drinking water

supply well.

� Depth to groundwater varied across the site from 4.9 feet to greater than 19 feet bgs. This data

suggests that there may be an old corridor passing through the central portion of the property,

perhaps an old river bed or utility corridor that may be influencing groundwater and contaminant

migration on the property.

� None of the off-site sensitive receptors appear to be impacted at this time; however, the presence of

residual petroleum contaminated soil is a threat to the source protection area for the Randolph

Village public community drinking water supply.

5.0 RECOMMENDATIONS

On the basis of the results of this investigation and the conclusions stated above, R.E.A. makes the

following recommendations.

1. Due to the presence of low concentrations of volatile petroleum compounds and TPH in

groundwater beneath the site, a groundwater sampling event should be completed in December

2011 to confirm the previous findings. Samples should be analyzed for the possible presence of

VOCs and TPH in accordance with EPA methods 8260 and 8015DRO.

2. The areas of visibly stained surface soil should be addressed to prevent possible exposure via

direct contact. At a minimum, the visibly stained surface soil should be managed in accordance

with applicable State guidelines, specifically the “Agency Guidelines for Petroleum Contaminated Soil and

Debris” dated August 1996.

3. A soil management plan should be prepared which documents the procedures to be followed

during the construction of the proposed secondary containment system and/or redevelopment of

the property. The soil management plan should also include the area of visibly stained surface

soil noted in the vicinity of the active ASTs.

4. The operator of the Randolph Village water system (WSID #5179) should be notified of the

findings of this investigation and presence of residual petroleum contamination discovered on the




5. A summary report should be completed following the next phase of site characterization, which

should include recommendations for possible remediation, long term monitoring, or site closure.
