SITE DESCRIPTION 1.0 The site is situated on a 19-acre parcel along Route 7 South in Middlebury, Vermont. The site facility consists of a 116,000 square foot manufacturing building on a cement slab foundation, and a smaller shed located northeast of the main building. Since 2007, the main facility building has been used for office and manufacturing space for Connor Homes, a producer of high quality manufactured homes. The facility includes a boiler room and shipping/receiving docks on the east side of the building. A groundwater sump is located in a vertical concrete chamber 16 feet beneath the facility boiler room. This sump is an original engineering control designed to collect water from a ne twork of foundation drains, pavement underdrains, and a storm water trench drain along the east side of the facility. The purpose of the drain network and boiler room sump is to prevent storm water and shallow groundwater from inundating the receiving dock area. An original (mid 1960’s) open construction electrical substation is located on the north side of the boiler room. The site location and site details relevant to this investigation are shown on Exhibit A-1.

BACKGROUND 2.0 Constructed in 1965, the site was owned and o perated by Standard Register and used as a printing facility from 1965 until 2007. A series of environmental investigations have taken place at the site since 1997. In 1997 an unspecified volume of #2 fuel oil was released at the site as a result of a fuel oil supply line leak in the facility boiler room. Fuel oil was found to have been released to a line trench in the boiler room which drained to a former drywell on the east side of the facility. Fuel oil product then migrated to pavement underdrains beneath the loading dock area, which collect to a dr ain manhole and t hen to the boiler room sump. The sump was configured to discharge to the stormwater sewer which daylights at a dr ainage swale on t he west side of Middle Road (Route 7S). V isible fuel oil impacts were addressed through emergency response actions by Environmental Products & Services (EPS), which included sorbent application/removal and s oil excavation near the drywell and observed “hot spots”. Recent environmental investigations were completed in 2007 with two Phase I Environmental Site Assessments (ESAs) along with another Phase I ESA in 2011 and two Phase II ESAs in that same year. Phase II investigations at the site identified a plume of dissolved phase chlorinated solvents, primarily trichloroethene (TCE), as well as evidence of fuel oil

contamination from the 1997 r elease. V iolations of Vermont regulatory standards existed for soil, groundwater, and indoor air. Phelps Engineering submitted a Corrective Action Plan to the State of Vermont Agency of Natural Resources (VTANR) Sites Management Section in March 2012 to address chlorinated solvent impacts to soil, groundwater, and indoor air. The VTANR approved the CAP which included excavation of the waste storage shed area, excavation of the facility floor drain lines, installation of a sub-slab ventilation system, and injection of emulsified vegetable oil and addition of microbial cultures to enhance bioremediation of subsurface contamination. The CAP was performed by Phelps Engineering and its subcontractors, as documented in the Corrective Action Summary Report dated March 17, 2013. As a result of CAP activities several monitoring wells were destroyed and later replaced near their original location. I n December 2012 a replacement well for ECS7 was installed approximately 12 feet north of its original location, near the northeast corner of the facility boiler room (well ECS7R). Soon after installation, replacement well ECS7R was found to have free-phase fuel oil and was not sampled at that time. In June 2013 Phelps Engineering bailed fuel oil Light Non-aqueous Phase Liquid (LNAPL) from the well and sampled groundwater with a bailer from the bottom of the well. Results showed TCE at a concentration of 1,650 mg/L. This concentration exceeds the theoretical solubility of TCE in water (1,200 mg/L), indicating the potential for TCE Dense Non-aqueous Phase Liquid (DNAPL) at this location. However, follow-up gauging with an interface probe has not indicated the presence of DNAPL at ECS7R. The nature and ex tent of TCE contamination at this newly discovered source area is the primary focus of this investigation.

SCOPE OF SERVICES 3.0 This scope of work was undertaken to further delineate the extent of TCE impacts to soil and groundwater in the vicinity of a ne wly discovered source area at the site. The general investigation area and the location of exploration activities are indicated on Exhibit A-1. The field effort for this work consisted of a geophysical survey, membrane interface probe (MIP) soil profiling, soil confirmation sampling, monitoring well installation, and the collection of groundwater samples for laboratory analysis. The investigation area includes a fenced-in privately-owned electrical substation on the north side of the boiler room. This scope of work included removal of the existing substation security fence and replacement with an 8-foot high chain-link stockade fence around the entire investigation area. F or the safety of Terracon personnel and subcontractors, invasive drilling in the substation vicinity was coordinated during a power shutdown to the facility over the weekend of August 10-11, 2013.



FIELD INVESTIGATION 4.0 Terracon carried out the scope of work in collaboration with Phelps Engineering, Inc. (Phelps). Terracon conducted the following work to further delineate the extent of TCE impacts to soil and groundwater in the vicinity of a new ly discovered source area at the site. P hoto log documentation of Terracon field investigation activities is included in Appendix D.

On July 31, 2013 Terracon observed a geophysical survey of the area of interest by Hager-Richter Geoscience, Inc. (Hager-Richter) of Salem, NH. The geophysical survey was conducted using time domain electromagnetic induction (EM), ground penetrating radar (GPR), and precision utility location (PUL). The area of interest for the geophysical survey is depicted on Exhibit A-1. A copy of the Hager-Richter Geophysical Survey Report is included as Appendix C.

On August 10 and 1 1, 2013, Terracon observed direct-push drilling and

Membrane Interface Probe (MIP) logging of twenty two (22) soil borings installed by Zebra Environmental of Albany, New York. The borings were drilled to between 10 and 18 feet below ground surface (bgs). MIP logs and supporting documentation are provided in Appendix D. A total of ten (10) confirmatory soil samples were collected by advancing five-foot geoprobe acetate sleeves from depth intervals indicating high MIP response from the Electron Capture Detector (ECD). The soil from each geoprobe sleeve was observed, characterized, and screened for the presence of VOCs using a 10.6 eV photoionization detector (PID) according to the USEPA jar headspace procedure. One (1) boring was completed as a 1-inch diameter monitoring well (TW-1), located to the northeast of the newly discovered source area. Boring logs and field documentation are included in Appendix D.

On September 10, 2013 t wo (2) additional soil borings were advanced by The

Verterre Group of Colchester Vermont. As shown in Exhibit A-1, these borings were completed as 1-inch diameter monitoring wells (TW-2, TW-3) and ar e located generally west and south of the newly discovered source area. Drilling and well completion were conducted under the observation of Phelps Engineering. Phelps Engineering boring logs are included in Appendix D.

On September 19 and 20, 2013, Phelps Engineering conducted a round of

groundwater sampling from 22 site monitoring wells. Depth to groundwater was gauged by Phelps Engineering and reported as elevations (see Appendix B Table 1). Groundwater samples were collected using low-flow methodology. Several wells exhibited poor recharge and w ere therefore sampled prior to stabilization of field parameters. ECS-7R was sampled by bailer due t o the



presence of fuel oil LNAPL (product removed by dedicated bailer prior to sampling with a new bailer). Samples were collected in laboratory-supplied containers and submitted for laboratory analysis of VOCs by EPA Method 8260B. Phelps Engineering field chemistry data from groundwater sampling are included in Appendix D. Exhibit A-3 depicts groundwater elevation contours and posted values for TCE concentrations in groundwater.

All site field work was completed under a Site Specific Health and Safety plan for each activity. Of particular safety concern was the presence of an original open construction electrical substation in the area of interest where invasive drilling was planned. For the safety of Terracon personnel and subcontractors, invasive drilling in the substation vicinity was coordinated during power shutdown to the facility. An eight foot high chain-link stockade fence was also erected around the entire investigation area to prevent unauthorized access to the restricted work area. In addition to Digsafe utility clearance, Terracon contracted with Vermont Underground Locators for geophysical survey and utility location for each area proposed for invasive work activities.

RESULTS OF THE FIELD INVESTIGATION 5.0 5.1 Geophysical Survey Prior to drilling activities Terracon contracted with Hager-Richter Geoscience to perform geophysical exploration. The purpose of this work was to identify the location of subsurface structures in the investigation area. Of particular interest was a suspected dry well and associated drain lines, shown near the northeast corner of the boiler room, as identified in a 1965 plan for Standard Register titled Boiler Room-Receiving Dock (Sheet 105 A) by The Austin Company. G eophysical exploration was also used to delineate the extent of granular fill materials and s ubsurface utility lines in the investigation area. Terracon contracted with Vermont Underground Locators to perform utility mark-out and clearance for additional drilling and monitoring well installation in the vicinity of the electrical substation and inside the production area of the facility. Geophysical survey methods included a combination of ground penetrating radar (GPR), electromagnetic induction (EM), and precision utility location (PUL). The various geophysical survey methods, including EM, GPR, and PUL, were used to locate subsurface utilities and to map the depth/extent of granular fill materials in the investigation area. No drywell structure was detected as a result of the geophysical survey. The GPR was useful in differentiating between native silt and clay materials versus granular fill materials due the variable signal penetration observed between known areas of fill (beneath the storm drain utility corridor) and undisturbed soils. An anomalous GPR reflection was interpreted by Hager-Richter to be a small unidentified buried object located near the overhead utility pole beneath the former security fence. A copy of the Hager-Richter report is included as Appendix C. Delineation of the extent of fill from the geophysical survey is included in Exhibit A-2.



5.2 MIP Soil Characterization The Membrane Interface Probe (MIP) is a percussion tolerant VOC sensor that can continuously log the presence of volatile organics in the subsurface that diffuse through a semi-permeable membrane. Using a carrier gas, the VOCs are brought to the surface through tubing which is connected to a l aboratory grade Electron Capture Detector (ECD), PhotoIonization Detector (PID) & Flame Ionization Detector (FID) for immediate analysis in the field. The direct-push hammer is connected to a retractable measurement device to determine accurate depth of the sensor as it is advanced into the subsurface. The resulting log records a continuous profile of instrument sensor readings with depth. On August 10 and 11, 2013, Terracon observed direct-push drilling and Membrane Interface Probe (MIP) logging of twenty two (22) soil borings installed by Zebra Environmental of Albany, New York. The borings were advanced to 10-12 feet below ground surface (bgs), with two borings (TF-10, TF-11) advanced to 18 feet near the source area to help define the vertical extent of CVOC impacts. MIP logs and s upporting documentation are provided in Appendix D. Prior to mobilization in the field, Terracon established a 3 foot sampling grid for the MIP investigation area. The sampling grid was taped-off in the field to provide a naming convention and spatial reference for the MIP borings. Transect lines were oriented parallel to the faces of the building. As shown on Exhibit A-2, grid location TG13 was positioned at the northerly building corner. A total of 15 MIP borings were completed at each 3’ grid spacing along two perpendicular transects through the suspected source area (transect line TF and l ine 11). Seven (7) additional MIP borings were completed at select grid locations in an attempt to fully delineate the presence of CVOCs in soil. Few borings were completed along transect TH due to access limitations imposed by the electrical transformer equipment. The presence of this equipment prohibits drill rig access further to the southwest from transect TH. Results from the MIP investigation show that ECD response provides a reliable indicator of CVOC impacts to soil. A high signal response observed from the PID and FID at many of the boring locations is indicative of residual fuel oil contamination encountered in the field. The ECD response is largely unaffected by the presence of petroleum hyrdocarbons and therefore provides a more reliable indication of relative concentrations of CVOCs in the subsurface. The ECD signal response is reported in units of millivolts. This signal may be correlated to specific contaminant concentrations in units of parts per million (ppm) based on laboratory analysis of confirmation samples. However, for the purposes of this investigation the ECD signal response was used primarily as a field screening tool to help define the location and volume of CVOC impacted soils in this newly discovered source area. Terracon evaluated the ECD signal response by incorporating the data into a 3D model previously developed for the site. A 2-dimensional overview of the relative ECD signal response at each boring is shown with the use of blue, orange, and red dots in Exhibit A-2. As shown in



Exhibit A-2, the horizontal extent of CVOC impacts in soil is adequately defined by low ECD response (blue) along the northerly and easterly limits of the investigation area with high ECD response (orange-red) near the northerly corner of the boiler room. The southwestern extent of CVOC impacts remains poorly defined due t o access limitations imposed by the electrical substation equipment and the building. As shown in the attached MIP logs the vertical extent of CVOC impacts based on high ECD response varies between 1.5 feet to 10.5 feet bgs. The shallowest high ECD response was observed at 1.5 to 7 ft bgs at boring location TH12. The strongest ECD response was observed at boring location TG11 where the signal response exceeded the upper calibration limits of the instrument between 1.75 and 10.5 feet bgs. 5.3 Confirmatory Soil Sampling A total of ten (10) confirmatory soil samples were collected by five-foot geoprobe acetate sleeves from depth intervals indicating high ECD response from the MIP. E ach geoprobe sleeve was observed, characterized, and screened with a PID for the presence of Total VOCs. Field screening was conducted using a using a PID with 10.6 eV lamp, calibrated to 100ppm Isobutylene gas (RF=1.0). Field screening measurements were conducted in accordance with the EPA soil jar headspace procedure. Upon initial observation and ECD screening results a sample was collected from each acetate sleeve for laboratory analysis of VOCs by field extraction in a laboratory-prepared container of methanol. An estimated sample depth was recorded with the sample ID based upon the geoprobe sampling interval and sample recovery. Field observations and screening results from confirmatory soil sampling are summarized in Table 1. A Photo Log with pictures of select confirmatory soil samples is included in Appendix D. As summarized in Table 1 (and in detail Table 2) soil samples submitted for laboratory analysis of VOCs by EPA Method 8260B indicate TCE concentrations in soil up to 1400 mg/kg (TE12 5ft). This particular sample coincides with a strong ECD response which exceeded the upper calibration limits of the MIP instrument (boring TE12). Confirmation samples indicate adequate correlation between ECD signal response and relative concentrations of TCE. 5.4 Groundwater Monitoring Groundwater analytical results from this investigation are summarized in Appendix B, Table 3. Groundwater chemistry data and gauging data collected by Phelps Engineering are summarized in Appendix E. Groundwater elevation contours and pos ted concentration values for TCE in groundwater shown on Exhibit A-3.



5.5 Geology/Hydrogeology The site geology and hydrogeology has been well documented in previous reports. The reader is referred to the March 2012 Phelps Engineering CAP for background information regarding the site geology. Observations from this investigation confirm the presence of horizontally-bedded silt and clay with interbedded lenses of silty sand at variable depths down to 10-12 feet below grade. These glaciolacustrine sediments are underlain by a dense glacial till of very low permeability and unde termined thickness. B edrock has not been en countered by previous investigations but is estimated at approximately 50 feet based on r egional geologic mapping. Native soils have been disturbed in various areas throughout the site as a r esult of site development, utility corridors, and recent stormwater drainage improvements. Disturbed areas have been backfilled with sand and gravel and reworked native soils (Fill). Fill varies in thickness throughout the site and is generally present down to 5-8 feet beneath the building and utility corridors, with deeper areas of fill observed down to 10 feet (MW-4). Structural fill used to support building footings and in the pipe bedding for site utilities is likely to consist of coarse gravel and sand with minimal reworked native materials. Groundwater is present at 4-6 feet below grade throughout the site. G roundwater flow is generally to the southwest at a s hallow gradient beneath the facility building (0.007), with steeper gradient (up to 0.06) observed between the shed and the main facility and between the facility and Route 7. Local variations in groundwater flow direction and gr adient are strongly influenced by areas of fill and the presence of the groundwater sump (located near the loading dock area of the facility). T his engineering control is designed, in part, to keep shallow groundwater from inundating the facility loading dock area and t herefore creates an e ffective local sink for groundwater flow. Water is pumped from the boiler room sump (and is now treated as a result of CAP implementation) and discharged to the storm water sewer utility. As shown in Exhibit A-3, monitoring wells MW-34 and MW-29R show depressed water table elevations as a result of the pumping influence of the boiler room sump. An anomalous groundwater elevation is observed at monitoring well TW-1 located immediately north of the newly discovered source area. As shown in Appendix E, gauging results from this investigation show the groundwater elevation at TW-1 is observed to be approximately 2 feet lower than that observed at ECS7R (located 15’ to the south). Well TW-1 is installed in an area of granular fill associated with recent stormwater drainage improvements at the site. Groundwater elevations at this location indicate groundwater flow may be influenced by the distribution of granular fill materials in this area.



INVESTIGATION DERIVED WASTES 6.0 Soil cuttings from drilling activities were raked over the area of highest observed contamination (area secured by 8-foot high chain-link stockade fence). Fuel oil product bailed from monitoring well ECS7R was poured into a 55-gallon accumulation drum in the facility waste storage room for later disposal.

SUMMARY 7.0 The following summarizes the results of this investigation based on the scope of work performed:

The geophysical survey of the investigation area does not show the presence of granular fill materials or any type of drywell structure in the vicinity of the newly discovered source area.

MIP soil characterization and c onfirmation sampling indicates a source of TCE impacted soil in the vicinity of the north corner of the Boiler Room. Impacted soils appear to extend beneath the electrical substation equipment and have not been fully delineated due to limited access.

Groundwater sampling at TW-1 indicates that contaminated groundwater is

present in the granular fill materials surrounding the stormwater utility adjacent to the source area.

We request the opportunity to discuss the results of this investigation so that we may evaluate options for remediation and/or additional characterization of this source area in an expedited manner.

RE: Geophysical Survey - Revised ReportConnor Homes1741 Route 7 SouthMiddlebury, Vermont

Dear Mr. Gaynor:

In this letter, we report the results of a geophysical survey conducted on July 31, 2013 byHager-Richter Geoscience, Inc. (Hager-Richter) at the above referenced site for Terracon ofManchester, New Hampshire (Terracon). The scope of the project and areas of interest werespecified by Terracon.

INTRODUCTION

The Site is an active modular home manufacturing facility known as Connor Homes,located at 1741 Route 7 South in Middlebury, Vermont. The general location of the Site isshown in Figure 1. Terracon is conducting an environmental investigation of the site that willinclude installation of soil borings, monitoring wells and excavations. Prior to drilling andexcavation, Terracon was interested in surveying the area of a former underground storage tank(UST) to locate utilities, piping associated with the former UST, and a possible dry well thatmight be present in an area of interest (AOI) at the site.

The AOI was specified by Terracon at the time of the survey to be a grassy areameasuring approximately 80 feet by 50 feet located adjacent to the rear of the building. Aportion of the AOI was located within a chain-link fence surrounding a power substation. Theapproximate limits of the geophysical survey are shown in Figure 2.

OBJECTIVES

The original objectives of the geophysical survey were to detect, and if detected, todetermine the locations of: 1) a former tank grave; 2) piping associated with the former UST;and 3) a dry well that may be present in the accessible portions of an exterior area of interest

specified by Terracon.

After completion of the survey, Terracon requested the development of a contour plotindicating the depth of granular fill in the area of the former tank grave, if detected.

THE SURVEY

Michael Howley of Hager-Richter conducted the field operations on July 31, 2013. Theproject was coordinated with Mr. James Gaynor of Terracon, who was on site for the duration ofthe geophysical survey and specified the limits of the area of interest.

The geophysical survey was conducted using complementary geophysical methods: timedomain electromagnetic induction (EM), ground penetrating radar (GPR), and precision utilitylocation (PUL). The EM data were acquired at approximately 8-inch intervals along linesspaced no more than 5 feet apart across the accessible portions of the area of interest. The EMsurvey detects buried metal. However, the EM method cannot provide information on the typeof objects causing an anomaly. The GPR survey was conducted along traverses oriented in twomutually perpendicular directions, with lines spaced no more than 2.5 feet apart across theaccessible portions of the area of interest. The GPR method is capable of detecting both metaland nonmetal objects. The PUL was used in passive mode to detect live electric lines, and inactive mode by transmitting a signal onto exposed utilities by direct connection and tracing theimparted signal.

EQUIPMENT

EM61. The EM survey was conducted using a Geonics EM61-MK2 time domainelectromagnetic induction metal detector. The EM61-MK2 instrument was designed specificallyfor detecting buried metal objects such as USTs, drums, and utilities. An air-cored transmitter coil generates a pulsed primary magnetic field in the earth, thereby inducing eddy currents innearby metal objects. The eddy current produces a secondary magnetic field that is sensed bytwo receiver coils, one coincident with the transmitter and one positioned 40 cm above the maincoil. By measuring the secondary magnetic field after the current in the ground has dissipatedbut before the current in metal objects has dissipated, the instrument responds only to thesecondary magnetic field produced by metal objects. Four channels of secondary response aremeasured in mV and are recorded on a digital data logger. The system is generally operated bypushing the coils configured as a wagon with an odometer mounted on the axle to trigger thedata logger automatically at approximately 8-inch intervals.

GPR. The GPR survey was conducted using a Sensors & Software Smart Cart NogginPlus digital subsurface imaging radar system. The system includes a survey wheel that triggers



the recording of the data at fixed intervals, thereby increasing the accuracy of the locations offeatures detected along the survey lines. The system was used with a 250 MHz antenna and a 60nsec1 time time window.

GPR uses a high-frequency electromagnetic pulse (referred to herein as "radar signal")transmitted from a radar antenna to probe the subsurface. The transmitted radar signals arereflected from subsurface interfaces of materials with contrasting electrical properties. Traveltimes of the radar signal can be converted to approximate depth below the surface by correlationwith targets of known depths. GPR data acquisition is monitored in the field and the GPR dataare digitally recorded for subsequent processing.

Data from the GPR survey were processed using EKKO_Mapper, commercially licensedGPR processing software from Sensors & Software, and the profile images were interpreted. Interpretation of the records is based on the nature and intensity of the reflected signals and onthe resulting patterns.

PUL. The PUL survey was conducted using a Radiodetection RD 4000 series PULinstrument. The RD 4000 series consist of separate transmitter and receiver. The system can beused in "passive" and "active" modes to locate buried pipes by detecting electromagnetic signalscarried by the pipes. In the "passive" mode, only the receiver unit is used to detect signalscarried by the pipe from nearby power lines, live signals transmitted along underground powercables, or very low frequency radio signals resulting from long wave radio transmissions thatflow along buried conductors. In the "active" mode of operation, the transmitter is used toinduce a signal on a target pipe, and the receiver is used to trace the signal along the length of thepipe. Our system uses either a 5W or 10W transmitter. We also used the CST Magna Trak 200which is a fluxgate magnetic gradiometer that detects subsurface metal objects by detecting alocal gradient in the earth's magnetic field.

LIMITATIONS OF THE METHODS

HAGER-RICHTER GEOSCIENCE, INC. MAKES NO GUARANTEE THAT ALLTARGETS OF INTEREST WERE DETECTED IN THIS SURVEY. HAGER-RICHTER GEOSCIENCE, INC. IS NOT RESPONSIBLE FOR DETECTINGTARGETS OF INTEREST THAT NORMALLY CANNOT BE DETECTED BYTHE METHODS EMPLOYED OR THAT COULD NOT BE DETECTEDBECAUSE OF SITE CONDITIONS.

1ns, abbreviation for nanosecond, 1/1,000,000,000 second. Light and the GPR signal require about 1 ns totravel 1 ft in air. The GPR signal requires about 3.5 ns to travel 1 ft in unsaturated sandy soil.



Field mark-outs. Utilities detected by the geophysical methods at the time of the survey aremarked in the field, and the operator makes every attempt, field conditions permitting, to detect andmark as many utilities as possible at the time of the survey. Adverse weather and site conditions(rain, snow, snow and soil piles, uneven surfaces, high traffic, etc.) can hamper in-fieldinterpretation. Utility mark-outs made on wet pavement, snow, snow piles, gravel surfaces, or inactive construction zones may not last. Hager-Richter Geoscience, Inc. is not responsible formaintaining utility mark-outs after leaving the work area.

EM61. The EM61 cannot detect non-metallic objects. The data from an EM61 surveyare adversely affected by surface metal. The EM61 has a depth sensitivity limited to about 12feet. The instrument is relatively cumbersome, and works best where the transmit and receivecoils can be hand pulled in a small trailer.

Detection and identification should be clearly differentiated. Detection is the recognitionof the presence of a metal object, and the electromagnetic method is excellent for such purposes.Identification, on the other hand, is determination of the nature of the causative body (i.e., whatis the body -- a cache of drums, UST, automobile, white goods, etc.?). Although the EM61 datacannot be used to identify all buried metal objects, they provide excellent guides to theidentification of some objects. For example, buried metal utilities produce anomalies withlengths many times their widths.

GPR. There are limitations of the GPR technique as used to detect and/or locate targetssuch as those of the objectives of this survey. Limitations include: (1) surface conditions, (2)electrical conductivity of the ground, (3) contrast of the electrical properties of the target and thesurrounding soil, and (4) spacing of the traverses. Of these restrictions, only the last iscontrollable by us.

The condition of the ground surface can affect the quality of the GPR data and the depthof penetration of the GPR signal. Sites covered with snow piles, high grass, bushes, landscapestructures, debris, obstacles, soil mounds, etc. limit the survey access and the coupling of theGPR antenna with the ground. In many cases, the GPR signal will not penetrate below concretepavement, especially inside buildings, and a target may not be detectable. The GPR method alsocommonly does not provide useful data under canopies found at some facilities.

The electrical conductivity of the ground determines the attenuation of the GPR signaland thereby limits the maximum depth of exploration. For example, the GPR signal does notpenetrate clay-rich soils, and targets buried in clay might not be detected.

A definite contrast in the electrical conductivities of the surrounding ground and thetarget material is required to obtain a reflection of the GPR signal. If the contrast is too small,



possibly due to construction details or deeply corroded metal in the target, then the reflectionmay be too weak to recognize and the target can be missed.

Spacing of the traverses is limited by access at many sites, but where flexibility oftraverse spacing is possible, the spacing is adjusted to the size of the target. The GPR operatorcontrols the spacing between lines, and the design of the survey is based on the dimensions ofthe smallest feature of interest. Targets with dimensions smaller than the spacing between GPRsurvey lines can be missed.

PUL. The PUL equipment cannot detect non-metallic utilities, such as pipes constructedof vitrified clay, transite, plastic, PVC, and unreinforced concrete, when used in passive modealone. Such pipes can be detected if a wire tracer is installed with access to such tracer fortransmission of a signal or where access (such as floor drains and clean-outs) permits insertion ofa device on which a signal can be transmitted. In some, but not all cases, the subsurface utilitydesignation equipment cannot detect metal utilities reliably under reinforced concrete becausethe signal couples onto the metal reinforcing in the concrete. Similarly, the method commonlycannot be used adjacent to grounded metal structures such as chain link fences and metalguardrails. In congested areas, where several utilities are bundled or located within a shortdistance of each other, the signal transmitted on one utility can couple onto adjacent utilities, andthe accuracy of the location indicated by the instrument decreases.

RESULTS

The geophysical survey was conducted using time domain electromagnetic induction(EM), ground penetrating radar (GPR), and precision utility location (PUL) methods across theaccessible portions of an area of interest specified by Terracon. Figure 2 shows the location ofthe area of interest for the geophysical survey. Figure 3 shows a color contour plot of the EM61results and a plot of the locations of the GPR traverses with the integrated interpretation of thegeophysical data. Figure 4 is a contour plot indicating depth of granular fill detected by the GPRsurvey within the AOI.

Interpretation of EM data is based on the relative response of the instrument in millivoltsto local conditions. The instrument is not calibrated to provide an absolute measure of aparticular property, such as the conductivity of the soil or the strength of the earth’s magneticfield. Subsurface metal objects produce sharply defined positive anomalies when the EM61 ispositioned directly over them. Acquiring data at short intervals along closely spaced lines, aswas done at the subject site, provides high spatial resolution of the location and footprint of thetargets. Thus, buried metal is recognized in contour plots of EM data by positive anomaliesroughly corresponding to the dimensions of the buried metal.



A few high-amplitude EM anomalies are evident in the color contour plot of the EM datashown in Figure 3. Most such anomalies are attributed to surface features such as building wallsconstructed of or containing metal, an above ground propane tank, an underground storage tank,and a chain-link fence. The locations of EM anomalies attributed to surface features are shownas blue hatched areas on the integrated interpretation shown in Figure 3. We note that thepresence or absence of subsurface metal objects in such areas cannot be determined on the basisof the EM data alone due to the anomaly caused by the surface metal objects.

Two low-amplitude linear EM anomalies not attributed to surface features are evident inthe plot of EM results shown in Figure 3. One such EM anomaly is attributed to the presence ofa metallic water line bisecting the area of interest from southeast to northwest. The second EManomaly is attributed to piping connecting an existing UST to the building. The locations of thedetected utilities are indicated on Figure 3.

The GPR survey was conducted across the accessible portions of the area of interestspecified by Terracon. GPR data were acquired along traverses spaced 2.5 feet apart andoriented in two mutually perpendicular directions. The locations of the GPR traverses and ourintegrated interpretation of the geophysical data are shown in Figure 3.

Apparent GPR signal penetration was variable, and ranged from limited to good acrossthe area surveyed. Two-way traveltime reflections were received from up to 40 - 50 nsec of 60nsec records in areas of good signal penetration, and from 10 - 15 nsec of 60 nsec records inareas of limited penetration. Based on a site-specific velocity matching calibration for the areaof interest, the GPR signal penetration is estimated to have been from as low as 1.5 to 2 feet to asmuch as 6 - 8 feet. The large area of limited GPR signal penetration is indicated on theintegrated interpretation in Figure 3.

The locations of possible utilities detected on the basis of GPR records are shown on theintegrated interpretation in Figure 3. One such utility is interpreted to be a drain line orientedparallel to the detected water line. The interpreted drain line connects to a catch basin present inthe AOI, and location of the drain line is shown on Figure 3. Two other utilities or utilitysegments were detected on the basis of GPR records, and their locations are indicated on theintegrated interpretation in Figure 3. We note that several other utilities, including a drain lineconnecting to a catch basin outside the AOI and several buried electric lines are indicated onplans provided by Terracon, but were not detected in the geophysical survey.

An unknown buried object (UBO) was detected on the basis of GPR records acquired atthe site. The location of the UBO, shown on Figure 3, is inside and close to the chain-link fencesurrounding the power sub-station. There was insufficient space to acquire useable EM datainside the chain-link fence, and we can not determine whether the UBO is metallic.



The PUL was used in passive mode to search for live electric lines and in active mode bydirectly connecting to a water valve located outside of the AOI. Due to the proximity of thepower substation and the presence of overhead power lines, we were unable to identify anyelectric lines or trace the water lines with the PUL.

At the request of Terracon, a contour plot indicating the approximate depth of granularfill was developed, and is shown in Figure 4. Depth of granular fill was determined by the lackof GPR reflections from below the interface between the granular fill and the silty clay presentbelow the fill. The depths indicated by the contours are based on the site-specific GPR signalvelocity calibration, and are estimated to have an accuracy of ± 1 foot.

We note that other areas of former excavations not indicated on Figure 4 are likelypresent within the AOI, specifically the areas above the detected water line. The material used toback-fill the water line excavation was likely similar to the native silt and clay, so the edges ofthe excavation do not produce GPR reflections.

CONCLUSIONS

Based on the geophysical survey performed by Hager-Richter Geoscience at the ConnorHomes facility located at 1741 Route 7 South in Middlebury, Vermont for Terracon, weconclude that:

• Multiple possible utilities and utility segments are present within the area of interestat the site

• A unidentified buried object was detected within the area of interest at the site

• The depth of granular fill was determined on the basis of GPR records acquired atthe site

• No UST with: (1) electrical properties sufficiently contrasting with the surroundingsoils to produce EM anomalies, or (2) a capacity of 500 gallons or more wasdetected within the effective depth of penetration of the GPR signal (from 2 to 8feet) in the surveyed area. Whether a UST occurs at a depth greater than theeffective depth of penetration of the GPR signal or in areas inaccessible to thegeophysical survey cannot be determined from the geophysical data.
