CDW CONSULTANTS, INC. 1

CDW Consultants, Inc. (CDW), on behalf of Design-Partnership of Cambridge, Inc., has conducteda Phase I Initial Site Investigation (Phase I) of a portion of the Essex Agricultural and TechnicalHigh School property located at 562 Maple Street in Danvers, Massachusetts. The disposal siteconsists of Building 29 (Farm Garage) which is a single story wood frame building and a parcel ofland located adjacent to the building (Site). The Site was initially reported to the MassachusettsDepartment of Environmental Protection (DEP) on December 15, 2011 for a release of petroleum togroundwater. The Site is listed as a DEP disposal site with Release Tracking Number (RTN) 3-30522.

1.0 INTRODUCTION

Between April 2007 and December 2011, preliminary Phase I and Phase II studies were completedat the Site in anticipation of future renovations at the school. Data used to support this Phase I wascollected from July 2011 through December 2011, and includes soil and groundwater samplelaboratory analyses results. This investigation was performed in accordance with MassachusettsGeneral Law (MGL) Chapter 21E and the Massachusetts Contingency Plan (MCP, 310 CMR40.000).

1.1 Purpose

The purpose of this Phase I Initial Site Investigation is to support a Tier Classification for the Site, toevaluate the impacts of a release of petroleum constituents reported to DEP in December 2011, andto evaluate current conditions to determine whether further assessment and/or response actions arerequired for the disposal Site to achieve compliance with the Massachusetts Contingency Plan(MCP).

2.0 GENERAL SITE INFORMATION

The property is identified on the Town of Danvers Assessors Map 12 as part of Lot 1, and is owned by the Essex Agricultural and Technical Institute. The vicinity of the disposal site appears on the

U.S. Geological Survey (U.S.G.S.) Danvers, MA (1995) Quadrangle Map. Figure 1 is a Site locationmap. The site coordinates are:

2.1 Site Location and Description

For the purpose of this Phase I investigation, the preliminary disposal site boundary is defined as anapproximate 6,000 square foot area including the northern third of Building 29 and the land arealocated adjacent and north/northeast of Building 29. Refer to Figure 2 (Site Plan) for theapproximate limits of the disposal site boundary. The Site is located with a current schoolrenovation and expansion project.

The subject site is located within the Essex Agricultural and Technical High School property. An

inspection of the Site building during CDWs 2011 subsurface investigation indicated that the Site building is used for storage of farm equipment with only light repairs conducted. One floor drain islocated within the building with an unknown discharge location. A 3,000 gallon gasolineunderground storage tank (UST) is located adjacent to and north of the building. A gasolinedispenser is located near the northeast corner of the building. A 300-gallon diesel above groundstorage tank (AST) is located at the northwest corner of the building on a concrete slab.

The Site is mostly paved or occupied by the building. The topography of the Site and surroundingarea slopes to the north and northeast. Access to the Site is currently restricted to employees of the

school and workers associated with the school renovation and expansion project. Access will beunrestricted after construction is complete.

2.2 Surrounding Land Use Description

The Site is located entirely within the boundaries of the Essex Agricultural and Technical HighSchool. A paved parking lot is located adjacent, west and south of the Site. Construction activitiesassociated with the school expansion project are ongoing to the north and northeast of the Site. Ahorse barn is located approximately 50 feet southeast of the Site. The estimated population within mile of the Site is between 250 and 500 people (MassGIS).

2.3 Natural Resources Review

The Site building is connected to the Town of Danvers municipal drinking water supply system.Drinking water is obtained from reservoirs and wells located in Middleton, Danvers, Peabody andLynnfield. No records of current (in use) irrigation or drinking water wells were found for the Site.

CDW obtained a Priority Resources Map from MassGIS. According to the map, the Site is notlocated within a current or potential drinking water source area. The nearest current drinking watersource area is a Zone II located approximately 0.85 miles southwest of the Site. The nearestwetlands are located approximately 450 feet north of the Site. According to the current NaturalHeritage Atlas, the Site does not lie within a Natural Heritage and Endangered Species protectedhabitat. Much of the surrounding school property or grounds is designated as Protected Open Space.The northern portion of the Site is located within an area of Protected Open Space. A copy of thePriority Resource Map is included as Figure 3.

The nearest downgradient surface water is a small pond located approximately 475 feet north of theSite. According to the MassGIS database, the Site is located outside of the 100 and 500 year floodzones.

2.4 State Records Review, MA Department of Environmental Protection

CDW reviewed the electronic DEP database records for state-listed properties for the school. Thefollowing databases were reviewed.

2.4.1 Registered Underground Storage Tank (UST) List (reviewed 11/28/12)

CDW reviewed this database known as the UST Query Tool published by the Massachusetts DEP.The database lists a current 3,000 gallon reinforced gasoline UST that was installed on June 1, 1985at the Site.

This database lists four other registered USTs at the Essex Agricultural and Technical High School.This includes three current steel 10,000 gallon USTs and one steel 1,000 gallon UST with unknowncontents installed on May 31, 1968. Two of the 10,000 gallon USTs were located at Smith Hall and

the Science Building and were removed in 1983 and 1992. The remaining USTs are locatedthroughout the school property.

2.4.2 Massachusetts Leaking Underground Storage Tanks (from MA DEP Database)

CDW reviewed the MA DEP Searchable Sites list for sites or releases that have a UST as the source.This database lists three leaking USTs within 1,000 feet of the Site. All three of these are located onschool property. The nearest is located at the Site (RTN 3-30522) and includes the associated 3,000gasoline UST. A 7,600 gallon fuel oil UST that was removed from Berry Hall in 1998 (RTN 3-17065) was located approximately 275 feet southwest and crossgradient of the Site. A third releaseassociated with a UST was located at Smith Hall (RTN 3-4409) located approximately 450 feetsouthwest and upgradient of the Site. Regulatory closure was achieved for the releases at BerryHall and Smith Hall.

2.4.3 State Listed Reportable Releases (reviewed 11/28/12)

CDW reviewed DEPs online Searchable Sites list. The Site is listed under RTN 3-30522 and wasreported to DEP on December 15, 2011. Additional releases located at the Essex Agricultural andTechnical High School are summarized below.

RTN 3-31134, Former Farm Office, Milk Barn, and Rodent Lab

This release was reported on October 1, 2012 due to the discovery of fuel oil contamination in soilafter the demolition of three buildings located approximately 250 feet northwest of the Site. ARelease Abatement Measure was conducted in October and November 2012 which included theexcavation and off-site disposal of approximately 2,300 cubic yards of impacted soil. Responseactions and assessment are currently ongoing.

RTN 3-30518, Building 18

Building 18 is located approximately 500 feet southeast of the Site and is the subject of a release ofvolatile petroleum hydrocarbons to soil. The source of the release is unknown, however based onsoil and groundwater data, appears to be localized. Assessment and response actions are ongoing.

RTN 3-17065, Berry Hall

A release of fuel oil from a former UST was documented at Berry Hall which is locatedapproximately 275 feet southwest and crossgradient of the Site. Approximately 30-40 cubic yards ofsoil was removed along with the UST in 1998. Regulatory closure was achieved; however residualsoil contamination is documented to remain beneath the building.

RTN 3-4409, Smith Hall

Smith Hall is located approximately 450 feet southwest and upgradient of the Site and is the locationof a former 10,000 gallon fuel oil UST that was removed in 1992. Approximately 205 tons of

impacted soil were excavated and disposed during the removal. Exploratory test pits were excavatedat the release location in May 2001 which indicated residual EPH concentrations below theapplicable MCP Method 1 Risk Assessment Standards. Regulatory closure was achieved in June2001 for that release.

2.5 Federal Records Review, U.S. Environmental Protection Agency (EPA)

CDW reviewed the following databases through online information:

2.5.1 National Priority List (NPL) (reviewed 11/28/12)

No NPL Sites are listed in the Towns of Danvers and Middleton.

2.5.2 CERCLA Sites (reviewed 11/28/12)

No CERCLA sites are listed within mile of the Site.

2.5.3 RCRA Hazardous Waste Generators List (reviewed 11/28/12)

Facilities listed on the Resource Conservation and Recovery Act (RCRA) Generators Database arerequired to comply with RCRA oil and hazardous waste management regulations. The Site is notlisted as a RCRA Hazardous Waste Generator.

8/10/2019 Document ID 195320

9/141




The school is listed as a RCRA Very Small Quantity Generator of Hazardous Waste under trackingnumber MV9787740050. According to Mr. Clifford Taylor, Agricultural Manager, very smallquantities of classroom wastes (approximately 1-2 gallons/year) are collected for disposal by alicensed disposal contractor. No wastes were generated in 2011.

2.5.4 Treatment, Storage and Disposal (TSD) List (reviewed 11/28/12)

No TSD facilities are currently located within mile of the Site.

2.6 Local Municipal Office Research

CDW reviewed files at the Danvers Board of Health and Engineering Department for informationregarding water and sewer connections to the Site. The Site building is connected to the municipalwater and sewer service. The building was constructed in the early to mid 1900s The DanversHealth Department indicated there are no private drinking or water supply wells within 500 feet ofthe Essex Agricultural and Technical High School property. Several documents related to asbestosabatement conducted at separate school buildings previously are on file.

Mr. Richard Rogers of the Danvers Engineering Department provided records on water and sewerservice. The Site building is connected to the municipal water and sewer systems, however theEngineering Department did not have any plans showing discharge locations of the building floordrain.

3.0 SITE HISTORY AND PREVIOUS INVESTIGATIONS

3.1 Site History

The Essex Agricultural and Technical High School was built in 1916 with additions in subsequentyears. Thirty nine buildings exist on the property and include academic and administrative

buildings, barns, maintenance buildings, and sheds. CDW reviewed aerial photographs of the Site

dated 1957, 1969 and 1978. The current Site building is depicted on all three photographs. The Site building was constructed in the early to mid 1900s The school parcel was undeveloped prior to1916 and likely was agricultural land.

3.2 Previous Investigations

April 2007 - Phase I Environmental Site Assessment (Maguire Group, Inc.)

A "Phase I Environmental Site Assessment" (ESA) was completed for the School in April 2007, byMaguire Group, Inc. (Maguire). The assessment included a site reconnaissance, document researchof the Site, and interviews with municipal officials and agency employees. The assessment includedthe Site building as well as other buildings that may be affected by future construction. Thefollowing are the conclusions of that report relative to the Site building. The Site building isconnected to municipal sewer, however some of the buildings located north of the Site are connectedto septic systems or holding tanks. A floor drain was observed in the Site building and the discharge

location was not evident.

Maguire recommended that a subsurface investigation be undertaken to evaluate the condition ofSite soil and groundwater specifically due to the existing gasoline UST and pump.

No issued notices of non-compliances with regard to applicable laws, regulations or standards werefound.

September 2011 Phase II Environmental Site Assessment (Maguire Group, Inc.)

From July 2011 through September 2011, Maguire completed a Phase II Environmental SiteAssessment. On July 20, 2011, three borings were drilled at the Site (Building 29). All three of the

borings were completed as two-inch diameter monitoring wells. The borings were placed adjacentto and downgradient of the gasoline UST, adjacent to the diesel AST and adjacent and south of the

building. PID headspace readings indicated elevated concentrations of VOCs in soil boring MGI-3located adjacent to and downgradient of the gasoline UST. The highest readings were found atdepths between 9 and 15 feet, at or near the groundwater table.

Soil samples from all three borings were analyzed for EPH, PAHs, VPH, and target VOCs.Detectable concentrations of EPH and VPH were found in the 11-13 foot depth sample from boring

boring MGI-3. None of the detected concentrations exceeded applicable Reportable Concentrations(RCs). No EPH, VPH, PAHs or target VOCs were identified in any other soil samples. BoringsMGI-1, MGI-2, and MGI-3 were renamed as wells MW-101, MW-102, and MW-103.

8/10/2019 Document ID 195320

11/141




Groundwater samples from all three wells were analyzed for EPH, VPH, PAHs and target VOCs.EPH, VPH, two diesel range PAHs and several VOCs were detected in groundwater from well MW-103 (MGI-3). The concentrations of two VPH fractions exceeded applicable RCs. The results ofMaguires investigation are included in Tables 3 and 4.

The conclusions of the report were that a MCP 120-day reporting condition existed due to a releasecondition of petroleum in groundwater and that further assessment and/or remediation would berequired prior to achieving a permanent solution.

3.2 OHM Use and Storage History

CDW reviewed available records at the Danvers Fire Department regarding aboveground andunderground storage at the Site. A 3,000 gallon gasoline UST was installed at the Site on June 1,1985. The UST was upgraded with stage 2 vapor recovery, spill containment and overfill protectionin 1994. Records of inspection in 2010 also were on file at the Fire Department. A 300-gallondiesel AST is located near the northwest exterior corner of the building. This tank is used forrefueling farm equipment. There were no records of this tank at the Fire Department. Records of several current and former USTs were on file at the Danvers Fire Department for the surroundingschool property.

3.3 Waste Management History

There is no waste management history for the Site.

3.4 Environmental Permits and Compliance History

No environmental permits were found for the Site.

4.0 HYDROGEOLOGICAL CHARACTERISTICS

CDW evaluated information from various sources, including U.S.G.S. topographic maps, GIS data,and flood insurance rate maps, to characterize the physical features of the Site and surrounding area.CDW also conducted a subsurface investigation at the Site, which included the advancement of soil

8/10/2019 Document ID 195320

13/141




5.1 Soil Borings and Monitoring Wells

On December 7 and 8, 2011, CDW advanced four soil borings (CDW-2, CDW-3, CDW-4 andCDW-5) and completed two of the borings as groundwater monitoring wells (CDW-3 and CDW-4).Borings CDW-2, CDW3 and CDW4 were advanced using the direct drive drilling method and

boring CDW-5 was advanced by the hollow-stem auger drilling method. Soil samples were obtainedusing the split-spoon sampling method at five foot intervals to 7 feet and continuously beyond 7 feet.Soil samples obtained by the direct drive method were obtained continuously, and classified on-site.CDW's subcontractor, Technical Drilling Services, Inc. of Sterling, MA completed the drilling of thesoil borings and the installation of the monitoring wells. CDW's subcontractor, SpectrumAnalytical, Inc. of Agawam, MA, completed the laboratory sample analyses.

The wells were constructed of 10 foot lengths of two- inch diameter slotted PVC well screen and asolid PVC riser. Uniformly graded sand was placed around the well screen to two feet above thescreen. One foot of bentonite grout was placed above the sand, followed by native fill to grade. A

protective roadway box was installed at grade. The wells were developed by purging with adisposable bailer for approximately 20 minutes.

The selections of the locations of the borings and monitoring wells were based on accessibility, andthe need to address data gaps from the previous investigation. Monitoring well CDW-3 was placed

downgradient and northwest of the gasoline UST and was set at a depth of 17 feet. Monitoring wellCDW-4 was placed downgradient and northeast of the UST and was set at a depth of 22 feet. BoringCDW-2 was placed north and downgradient of the UST and boring CDW-5 was placed east of thegasoline pump and UST.

Soils encountered during drilling were moderately dense, native material consisting of predominantly fine sand with some gravel and cobbles. Groundwater during drilling was observed between depths of approximately 9 and 14 feet below grade. Figure 3 shows the locations of the soil borings and the monitoring wells installed by CDW as well as borings previously installed by others

on the Site. Soil boring logs are included in Appendix A.

8/10/2019 Document ID 195320

14/141




5.2 Soil Screening and Laboratory Samples

Soil samples were collected from each boring and field-screened with a photoionization detector(PID) using the headspace method. The soil headspace screening results are presented in Table 1.The PID is an instrument used to quantify volatile organic compounds (VOCs) with a detection limitof one part per million (ppm). The following methodology was employed for the headspacescreening:

Collect the sample up to one-half the capacity of a clean glass jar. Cover the top of the jar with aluminum foil. Tightly place the jar cover on top of the

aluminum foil sheet. Vigorously shake the jar contents for at least 15 seconds to allow for volatilization of

the organic compounds into the air space. Allow the jar to sit for 1 minute at room temperature. Carefully remove the jar cover

without removing the aluminum cover. Quickly insert the PID probe into the jar byforcing it through the aluminum cover.

Read the maximum total PID level. Express the level in ppmv as benzeneequivalent.

The sampling plan was developed to investigate the types of compounds that may have beenreleased from previous on-site spills and the use of the Site for automobile and equipment repairs.One soil sample from each of four borings was submitted for laboratory analysis for extractable

petroleum hydrocarbons (EPH), polynuclear aromatic hydrocarbons (PAHs), volatile petroleumhydrocarbons (VPH), and volatile organic compounds (VOCs) by EPA Method 8260. The sampleswere collected from depths between 10 and 17 feet below the ground surface. A trip blank andduplicate sample were also prepared and submitted to the laboratory for VOC analysis for QA/QC

purposes. The samples were preserved by refrigeration and methanol, as appropriate, and deliveredto the laboratory accompanied by an appropriate chain of custody record.

5.3 Groundwater Gauging and Quality

On December 15, 2011, monitoring wells CDW-3 and CDW-4 were gauged for depth togroundwater and the presence of non-aqueous phase liquid (NAPL) using an oil/water interface

probe. Measurements were referenced to the top of the PVC riser. No NAPL was observed in any

8/10/2019 Document ID 195320

15/141




of the wells. Groundwater was measured at depths ranging from 9.15 to 14.5 feet below the top ofthe well riser.

Water quality parameters including pH, temperature, and conductivity were measured in each wellwith a downwell probe after purging. The results of groundwater gauging and water quality areincluded in Table 2.

5.4 Groundwater Sampling

On December 15, 2011, CDW collected groundwater samples from newly installed monitoring wellsCDW-3 and CDW-4. Three well volumes were removed prior to sampling. Groundwater samples

were obtained with dedicated polyethylene bailers. Samples were obtained for laboratory analysesfor EPH, VPH, PAHs, and target VOCs. A trip blank was also prepared and submitted to thelaboratory for VPH and target VOC analysis for QA/QC purposes. The samples were preserved byrefrigeration and hydrochloric acid, as appropriate, and delivered to the laboratory accompanied byan appropriate chain of custody record. The required filtering of EPH samples prior to analysis was

performed by Spectrum.

6.0 NATURE AND EXTENT OF CONTAMINATION

For the purpose of identifying the Method 1 risk assessment (RA) standards, as defined in the MCP310 CMR 40.0930 for the present and foreseeable future land uses of the Site relative to soil, thesurficial soil to a depth of 3 feet is classified as S-1 in unpaved areas, due to the accessibility of thesoil and the assumed current and future frequency of use by adults and children. The soil at the Sitefrom 0 to 15 feet in paved areas, and from 3 to 15 feet below grade in unpaved areas is classified asS-2, as follows:

The soils at the Site are potentially accessible The intensity of use by adults and children is considered to be low

The assumed frequency of use by adults and children is considered to be high

However, to evaluate both the current and foreseeable future risk of harm without assumingrestrictions to Site uses, all soil from depths of 0 to 15 feet below grade was compared to Method 1S-1 standards. The soil at a depth greater than 15 feet below grade is classified as S-3 for isolated

8/10/2019 Document ID 195320

16/141




subsurface soils.

For the purpose of identifying the applicable RA standards, as defined in the MCP, 310 CMR40.0932, for the present and foreseeable future land uses of the Site relative to groundwater, thegroundwater categories are designated as GW-2 and GW-3, due to the following:

The groundwater is located at a depth less than 15 feet within 30 feet of anoccupied building

The groundwater potentially discharges into surface water

The results of the laboratory analytical testing of soil and groundwater samples were evaluated andcompared to MCP Method 1 RA standards for unrestricted uses and are summarized in Tables 3 and4. Copies of the laboratory reports are included in Appendix B.

6.1 Soil Sample Analysis Results

Soil samples were collected during drilling and screened with a PID using the headspace method.The results ranged from 0.1 to 159.9 parts per million by volume (ppmv). The results of theheadspace screening are summarized in Table 1.

Laboratory analytical results showed detectable concentrations of VPH in two soil samples andVOCs in one sample. The sample from the 15-17 foot depth from boring CDW-4 showed thehighest concentrations of VPH. No EPH or PAHs were detected in the samples from CDWsDecember 2011 investigation. None of the detected concentrations of VPH or VOCs exceededapplicable MCP Method 1 standards.

The EPH, VPH and target VOC analytes that were detected above the laboratory reporting limits aresummarized in Table 3.

6.2 Groundwater Sample Analysis Results

Groundwater samples were collected from monitoring wells CDW-3 and CDW-4 for laboratoryanalysis. The samples were analyzed for EPH, PAHs, VPH, and target VOCs. The results of the

8/10/2019 Document ID 195320

17/141




groundwater sampling and analysis reported detectable concentrations of EPH, VPH and severalVOCs in monitoring well CDW-4. No EPH, VPH, PAHs or VOCs were detected in CDW-3.

The results of EPH, VPH, and VOC analyses above the minimum detection limit are summarized inTable 5 .

6.3 Extent of Contamination

Based on the data collected from Maguires investigation in July and August 2011 and CDWsinvestigation in December 2011, petroleum constituents were detected in three of seven borings atthe Site. The highest concentrations were detected in MGI-3 located adjacent and downgradient of

the gasoline UST at a depth of 11-13 feet. None of the detected concentrations in soil exceededapplicable Method 1 standards. Analysis of groundwater from four monitoring wells indicated

petroleum contamination in groundwater located downgradient of the gasoline UST and pumpisland. The highest concentrations were found in well MW-103 located adjacent to anddowngradient of the gasoline UST. The concentrations of VPH in that well exceed applicableMethod 1 standards. Based on the presence of VPH, the source of contamination appears to be thegasoline UST system. The groundwater data suggest that the contaminant plume in groundwaterappears to have migrated to the northeast.

7.0 IMMEDIATE RESPONSE ACTIONS EVALUATION

CDW evaluated the Site for imminent hazard conditions. In accordance with 310 CMR 40.0426, noimminent hazard conditions were identified as part of this investigation.

8.0 MIGRATION PATHWAYS AND EXPOSURE POTENTIAL

CDW evaluated the potential impacts from the Site conditions identified. Known or potentialimpacts from the Site conditions include migration pathways and possible exposures by both humanand environmental receptors.

8.1 Known or Potential Migration Pathways

Underground utilities include sewer and drain lines for the floor drain in the building andunderground fuel lines for the UST system. Based on the topography of the area, the drain line may

8/10/2019 Document ID 195320

18/141




be located to the east or north of the building. Underground utilities in the adjacent eastern roadway,if present, may also represent a potential migration pathway for contaminants found in the area ofCDW-4. The Site is not located within a current or potential drinking water source area. There areno private drinking water wells located within 500 feet of the school property.

The Site area is served by municipal water and sewer. Some of the buildings located north of theSite may have used on-site septic systems. Depth to groundwater was measured between 9 and 14feet. Petroleum compounds and VOCs were not detected in well MGI-1 located on the south side ofthe building, and the contaminant plume appears to have migrated with the direction of groundwaterflow to the north. Indoor air is not considered a potential pathway for contaminant migration.

Stormwater from the Site may flow overland on paved areas located north and east of the buildingand infiltrate into unpaved areas located north and downgradient. Groundwater was calculated toflow in a northeasterly direction.

8.2 Known or Potential Human Exposure

The materials present at the Site and their primary exposure routes are as follows:

Material Physical State Exposure Route

VPH/VOCs Vapor Inhalation, Absorption,Ingestion

EPH/PAHs Solid/Liquid Absorption, Ingestion

EPH and VPH compounds, some PAHs, and some VOCs are generally associated with petroleum products, including fuel oil and gasoline. Potential human exposure to EPH and VPH in soils occurs primarily due to direct contact, or contact with disturbed soil particulates containing thesecompounds. Potential human exposure to EPH and VPH contamination found in soil may occurthrough direct contact with soils on-Site such as if subsurface excavation is performed for utility

work.

EPH and VPH compounds and metals are somewhat soluble in water. Larger molecular weight EPHand metal compounds will often be retained within the soil matrix, with the lighter EPH compoundsvolatilizing or dissolving into groundwater. Potential human exposure to EPH and metals

contamination in soil may occur through direct contact with soils on-site such as if subsurfaceexcavation is performed for utility work.

VPH and VOCs typically range from slightly soluble to highly soluble and tend to migrate ingroundwater. Potential human exposure to VPH and VOCs may occur as a result of inhaling vaporswhich migrate through utility conduits or disturbed soil. VPH and VOC vapors may also migratethrough soils into building structures.

8.3 Known or Potential Environmental Exposure

The Site is mainly paved with asphalt or covered by the building. Wildlife and farm animals are

present in nearby buildings, in wooded areas, and in downgradient wetland areas. The nearestresidences are located approximately 750 feet southeast of the Site. No natural resource areas wereidentified at the Site. A Zone II for a public water supply is located approximately 0.85 milessouthwest of the Site. The nearest surface water body is the unnamed pond located approximately450 feet north of the Site.

9.0 CONCLUSIONS AND RECOMMENDATIONS

Based upon our research, subsurface testing, and site observations CDW is presenting ourconclusions and a summary of the key observations upon which these conclusions are based. Fromthis study, CDW has made the following conclusions:

The Site is improved by a garage for farm equipment that was constructed in the early to mid1900s. A 3,000 gallon gasoline UST and dispenser are located adjacent and north/northeastof the Site. A 300 gallon diesel AST and dispenser is located adjacent to the northwestcorner of the building. Light repairs of farm equipment are conducted within the building.An active floor drain is located in the building with an unknown discharge location.

Previous investigations at the Site include a Phase I Preliminary Site Assessment by Maguirein 2007 and a Phase II Subsurface Investigation by Maguire in August 2011. The Phase IIInvestigation included three soil borings which were all completed as monitoring wells. Theresults of the Phase II indicated a reportable concentration of two VPH fractions ingroundwater from a well located adjacent to the gasoline UST.

8/10/2019 Document ID 195320

20/141




In December 2011 and January 2012, CDW completed a supplemental subsurfaceinvestigation at the Site to determine the extent of groundwater contamination identified bythe Maguire study. Four soil borings were completed and two of the borings were completedas monitoring wells. VPH was detected in two soil borings located downgradient of the USTand VPH was detected in a monitoring well located northeast and downgradient of the UST.

Petroleum contamination at the site appears in both soil and groundwater. The highestconcentrations of VPH were detected in groundwater located adjacent and downgradient ofthe gasoline UST. Based on the contaminants identified and the location of contaminantsfound, the gasoline UST system is the likely source of the release. The contaminant plumehas migrated in the northeast direction with the groundwater gradient, however lowerconcentrations were found with increased distance from the UST.

CDW recommends the following to further investigate the environmental condition of the Site:

In accordance with 310 CMR 40.0486, CDW is of the opinion that further assessment and/orresponse actions will be required at the disposal Site before the requirements of a ResponseAction Outcome can be met. This will include soil and groundwater sampling duringremoval of the gasoline UST system and diesel AST.

CDW recommends that a floor drain study be conducted to identify the potential dischargelocation of the floor drain.

A Phase II Scope of Work has been prepared which summarizes the steps to maintainregulatory compliance.
