1.0 EXECUTIVE SUMMARY

Otter Creek Engineering, Inc. was retained by Beatrice Gerow--Elmore to perform a Phase II Environmental Site Assessment (Phase II ESA) of the GLR, LLC Property (the Property) located on U.S. Route 7 (Court Street) in Middlebury, Vermont. Otter Creek Engineering performed the Phase II Environmental Site Assessment in conformance with ASTM Standard Practice E 1903 .. 97 between July 12, 2006 and February 8, 2007.

In July, 2006, Otter Creek Engineering supervised the drilling of five (5) soil borings on the Property, the installation of five (5) groundwater monitoring wells, field screening of soil samples using a photoionization detector (PID), and the collection of groundwater quality samples for laboratory analysis. The data indicated that the volatile organic compounds (VOC) solvents perchloroethene (PCE) and trichloroethene (TCE) were detected in groundwater from one monitoring well. The PCE concentration greatly exceeded the Groundwater Quality Enforcement Standard (GQES). The Vermont Department of Environmental Conservation (VDEC), Sites Management Section (SMS) was notified and classified the Property as Hazardous Waste Site #2006--3560. A second water quality sample from the well showed lower concentrations of PCE, above the GQES, but no TCE.

Otter Creek Engineering then submitted a proposal for an additional contaminant investigation to further identify the degree and extent ofVOCs contamination on the Property, through the installation of fifteen (15) shallow soil borings, collection of soil gas samples using Gore .. Sorber® Modules, and analysis of the Modules for VOCs at the W.L. Gore and Associates, Inc. (Gore) Laboratory. The proposal was approved by the SMS, and the investigation completed. Data collected during the investigation defined the presence of a soil gas plume beneath the building and south end of the Property that consists of the dry cleaning solvent PCE and its daughter products TCE and dichloroethene (DCE). Also detected in the soil gas are lower estimated concentrations ofVOCs associated with petroleum fuels (gasoline and diesel range aromatics), and total petroleum hydrocarbons (TPH).

This data indicates the presence of a PCE release on the Property, resulting in impacts to soil and groundwater. Review of the PCE contour maps for soil gas indicate that the source of the PCE is most likely from a spill or release during operations at the Desabrais Laundry & Dry Cleaning (DLDC) facility, which has occupied the eastern half of the GLR, LLC building since 199 5. Additional investigative work is proposed to be completed in order to further define the degree and extent of PCE contamination, and to define the PCE source, on the Property.

2.0 INTRODUCTION

Otter Creek Engineering, on behalf of the owner Beatrice Gerow--Elmore (GLR, LLC), has completed the following Phase II Environmental Site Assessment (Phase II ESA)


© 2007 1

in accordance with ASTM Designation: E 1903--97, Standard Guide for Environmental Site Assessments: Phase II Environmental Site Assessment Process. The Phase II ESA was performed between July 12, 2006 and February 08, 2007 on the GLR, LLC Property (the Property), located on the south side of U.S. Route 7 in Middlebury, Vermont. The general location of the Property is shown on Sketch A. Drawing No.1 is an orthophotograph showing the GLR, LLC Property and Surrounding Properties and Uses.

2.1 Purpose .. The purpose of this Phase II ESA is to identify, describe, and evaluate, to the extent feasible pursuant to the processes prescribed herein, recognized environmental conditions in connection with the GLR, LLC Property.

2.2 Special Terms and Conditions .. There are no special terms or conditions for this Phase II ESA.

2.3 Limitations and Exceptions .. This Phase II ESA report that is specific to the· Property in Middlebury, Vermont has been prepared for the exclusive use of Beatrice Gerow-Elmore and GLR, LLC, and for "Old Men in Baggy Pants, LLP". Field and laboratory activities on the Property were limited to the following:

a. Use of a portable photoionization detector (PID) to analyze air for the presence of volatile organic compounds (VOCs) from the building interior and groundwater monitoring wells installed on--site.

b. The collection and descriptive logging of soil samples from soil borings drilled on--site.

c. The collection of groundwater samples from the monitoring wells and their analysis for VOCs at the Endyne, Inc. Laboratory.

d. The installation and retrieval of Gore--Sorber® adsorbent sampler modules placed in shallow soil borings.

e. Analysis of the Gore--Sorber® modules at the W.L. Gore & Associates, Inc. (Gore) laboratory for the presence ofVOCs in soil gas.

The site visits and report did not assess the presence of asbestos--containing materials, radon, lead--based paint and/or any other potential contaminants requiring specialized testing procedures or sampling on the Property with the exception of those specified.

This Phase II ESA was a comprehensive attempt to identify, describe and evaluate recognized environmental conditions associated with the Property. There is the possibility that some environmental conditions have escaped recognition due to the limitations of the previously completed Phase I ESA and the current Phase II ESA, the inaccuracy of Federal, State and Local records, or the presence of undetected or unreported events. Otter Creek Engineering, Inc. has performed the Phase II ESA

d. Collection of groundwater samples from the groundwater monitoring wells and their laboratory analysis for VOCs via EPA Method 8260.

e. Review of the groundwater quality sample data showing the presence of the dry cleaning chemical solvent VOCs perchloroethylene (PCE) and trichloroethylene (TCE) in a monitoring well, and generation of a letter summary report (dated August 3, 2006).

f. Installation of fifteen (15) shallow soil borings and Gore ... Sorber® Modules on the Property to evaluate the extent ofVOCs in shallow soil gas.

g. Retrieval of the Modules and their laboratory analysis via modified EPA Methods 8260/8270 for mass ofVOCs, estimated soil gas concentrations, and generation of a soil gas summary report by Gore.

h. Compilation of the data collected and generation of this Phase II ESA summary report.

3.0 BACKGROUND

3.1 Site Description and Features ... The subject Property is located in a residential and commercial area approximately one mile south of the downtown or village of Middlebury (Sketch A). The Property is bound on the north by U.S. Route 7, on the west and south by Middle Road North, and on the east by a commercial property owned by Old Men in Baggy Pants, LLC, and currently occupied by the One Dollar Store.

The one--story building, constructed in 1974 as a pole bam, is centered at the


© 2007 Page 3

southern end of the Property. The building measures 150 .. feet long by 60 .. feet wide, and contains 9,000 square feet (ft2

) of interior space. The building is divided longitudinally into two (2) rental units, each measuring 15Q .. feet by 3Q .. feet and containing 4,500 fe in area. One unit, on the eastern half of the building, is leased by Desabrais Laundry and Dry Cleaning (D LDC). The second unit, on the western half of the building, was formerly leased by Middlebury Discount Foods (MDF).

A gravel driveway off Middle Road North provides access to the south end of the building. Two paved entrances off the east side of Middle Road North and one paved access from the adjoining One Dollar Store parking area provides access to au .. shaped paved parking area at the central and north end of the Property. Unpaved grass lawn areas are located on the west side of the paved parking area, and the east, south and west sides of the building.

The building, DLDC and MDF facilities, parking area, lawn areas, roads, utilities, and pertinent site features are shown on Drawing No.2, "Site Plan and Adjacent Properties".

3.2 Physical Setting .. The topography of the Property is generally level, with gentle slopes toward Middle Road North to the west, southwest and south as shown on Sketch A, General Location Map [a United States Geological Survey (USGS) 7.5 Minute Topographic Quadrangle map], and Drawing No.2, Site Plan and Adjacent Properties. The elevation relief on the Property· is about 7 .. feet, with the greatest elevation of about 3 71.-feet at the northeast comer and the lowest elevation of 364 .. feet at the southwest corner. Located approximately 1 ,2QO .. feet southwest of the Property, Otter Creek flows to the north and is the main surface water body and groundwater discharge zone in the region.

3.3 Site History and Land Use .. Originally the Property was part of a larger parcel that also included the property to the east that is now occupied by the One Dollar Store. Following purchase of the larger undeveloped parcel in 1944, Raymond and Robert Gerow constructed a building near the northeast corner of the property for use as a bowling alley, which was operated for many years. The bowling alley building is now currently occupied by the One Dollar Store. In the 1950's the larger parcel with bowling alley building was subdivided into two (2) parcels. At that time the existing GLR, LLC Property was created and was undeveloped.

During the mid to late 1970's the north portion of the undeveloped Property was used for the temporary storage of new and used automobiles. The automobiles were temporarily -stored on ... site when the Brush Motors dealership [formerly at the current location of Phinney's Paint and Decorating northwest of the Property] lot was full. Mr. Cory Foote, Representative, Property Manager and Agent for Betty Gerow .. Elmore (GLR, LLC) stated that no vehicle repairs or maintenance were performed on.-site. In 1974 a pole.-barn

GLR,

style building was constructed in the southwest corner of the Property. The pole barn building (the existing GLR, LLC building) was used for storage. On August 4, 1981, Constance Gerow and Mrs. Beatrice Gerow applied for a building change in use for conversion of the building from warehouse space (9,000 ft2

) to retail (Middlebury Bowling Lanes showroom, 2,250 ft2) and

warehouse space (6,250 ft2), used by the Gerow plumbing and heating business.

Approval for permit #81,128 was granted on September 4, 1981.

On July 8, 1982, Highland Press (owned by McGrath & McGrath, Inc.) applied for a building change in use and repainting of the building sign. Highland Press leased approximately 4,500 ft2 within the northern half of the building, with 2,250 ft2 for printing offices and 2,250 ft2 to accommodate printing press and paper storage. The existing 4,500 ft2 warehouse southern portion remained in use by the Gerow plumbing and heating business. An existing flat sign on the front of the building was to be repainted. Approval for permit #82, 107 was granted on August 18, 1982.

Information pertaining to hazardous waste use by the former tenant Highland Press was provided on October 16, 2006 by Lyn Metcalf of the Vermont Department of Environmental Conservation (VDEC), Hazardous Waste Management Division (WMD) .. File information included an August 19, 1985, Notification of Proposed Hazardous Waste Activity form, completed by Kristen Travers, Manager of Highland Press. A copy of the form is included in Appendix A. Ms. Travers' brief written description of the hazardous waste generation and disposal activities noted that: "we purchase, use, & dispose of several developing & fixing chemicals (photographic) & cleaning solvents." A list of chemicals used included "PMT Developer, Ultratech Developer & Fixer, Durographic Activator & Stabilizer, Enco Plate Developer & FPC, and Alcohol & Blanket Wash". The method of waste treatment or disposal was described as: "Waste is flushed down sink drains generally. Fixer is sent out to silver refining company. Wastes are stored in drums (metal & plastic)". A search on the internet of Material Safety Data Sheets (MSDS) for these chemicals indicates the following: "Enco FPC" contains hazardous ingredients listed as "High Boiling Petroleum Spirits"; "Durographic Activator" contains "sodium hydroxide and sodium sulfite"; "Durographic Stabilizer" contains "cyclohexanone, thiocyanic acid and acetic acid"; and "blanket wash" may consist of a variety of chemical ingredients, including "aliphatic petroleum distillates", "mineral spirits", "naphtha", "ethyleneglycol monobutylether", and "perchloroethylene" (PCE).

On May 6, 1988, Mike Nelson of the ANR performed a "Status Determination" inspection of the Highland Press facility with "Bill Hanlon, Owner". A Trip Report and Inspection Checklist were completed and copies are included in Appendix A. In the "Hazardous Waste Streams" report section

Mr. Nelson states: "The inkwells of all three presses are cleaned daily. Less than a pound of ink per week is thrown out. Approximately three gallons of photochemicals are dumped down the drain each month. Press clean solvents and waste ink from the rollers is wiped up on rags supplied by Foley's Services of Rutland. Foley's supplies Highland Press with 50 rags per week." It is not known whether these chemicals contained PCE. Under the "Actions Taken" report section Mr. Nelson states: "A letter was sent to Mr. Hanlon recommending alternative methods of waste photochemical disposal." Mike Nelson, Environmental Technician, sent the letter to Mr. Bill Hanlon on May 19, 1988. A copy of the letter is included in Appendix A. The following was stated in the letter: "I am writing you following the hazardous waste inspection at Highland Press on May 6, 1988. Dumping waste photochemicals down the drain into the municipal sewer system is not an environmentally sound disposal method. The method is acceptable only after the silver has been extracted."

On August 8, 1992, "Peg Qoyce) Cobb, Agent for Middlebury Hardware (Video King and DeGray's Barbershop)", submitted a permit application (#92 .. 113) for "interior renovations to Highland Press space, new door, signs, define parking area, lights". Proposed renovations within the former Highland Press lease space included a hardware store, a video store, and a barbershop. Included in the application file are two (2) floor plan sketches by Fred Dunnington, Town Planner (Appendix B). The "exist" sketch shows the building layout when Highland Press occupied the building, including a customer area, two offices, a bathroom, a large printing area, and the Gerow plumbing and heating business warehouse. The "proposed" sketch shows a hallway, bathroom, hardware store, video store, barbershop, and the Gerow plumbing and heating business warehouse.

On December 10, 1993, Steven Pollinger, of Pollinger's Own, Inc., applied to convert 2,850 fe in the building (the area formerly occupied by the Middlebury Hardware Store) into a retail grocery store (MDF). Two (2) flat signs were to be constructed for installation on the building, and one ( 1) freestanding sign was to be installed near U.S. Route 7. Permit #93 .. 151 was issued on December 10, 1993.

On February 14, 1995, Steve Noble, of Desabrais Laundry, applied to complete interior renovations for a laundromat/dry cleaning business (2, 760 fe) at the former location of the video store. In addition, a new 30 .. foot by 30 .. foot room for utility equipment was to be constructed in the southern part of the building, and a new 6 .. inch municipal sewer service and 4 .. inch municipal water service were to be constructed for the estimated 7 ,OOO .. gallons per day (gpd) water and sewer demand. At that time MDF occupied a portion of the building. A new flat sign was to be installed on the building~ A sketch of the proposed floor plan showing general locations of a lounge area, clothing storage, washers,

3.4 Adjacent Property Land Use ... Current uses of lands adjoining the Property include undeveloped land (presently under construction), retail businesses and commercial facilities. To the north of the Property, across U.S. Route 7, are two (2) commercial businesses, Century 21 Jack Associates (a realty agency) and Mackey Insurance (an insurance agency), and a municipal wastewater pump station. To the northeast across U.S. Route 7 is Rogers Road, which serves as the entrance to a single family residential (SFR) development further to the north and northeast. East of Rogers Road is a commercial business, Total Image Salon (a hairdresser). East and southeast of the Property is the One Dollar Store, a retail household items business where most items sell for one dollar. Across Middle Road North to the south, southwest and west of the Property is the Middlebury South Village (MSV) multi ... lot SFR development that is presently under construction. Also across Middle Road North to the west of the Property is Citizens Bank, a commercial bank branch. The Property, building, parking area, roads, and adjoining properties are shown on Drawing No. 1 and Drawing No.2.

Included within the Phase I ESA Report are the USGS 7.5 .. minute Topographic maps for Middlebury, Vermont in 1963 and 1983 (ppotoinspected), and for Cornwall, Vermont in 194 3, 1972 (photoinspected) and 1983 (photoinspected), which were reviewed and indicate that in 1963 the Property was vacant and undeveloped. The bowling alley (currently the One Dollar Store) building was present on the adjacent property to the east. The One Dollar Store building was apparently provided heat from fuel oil stored in a UST located in the parking area at the front (north) of the building (Drawing No.2). At the time the Phase I ESA was completed in January 2007, it was not known whether the UST was in place or had been removed. On February 8, 2007, Andy McCabe, one of the owners of the One Dollar Store property, stated in a telephone conversation with Bill Norland, C.P.G., of Otter Creek Engineering, that the fuel oil UST had been removed in September, 2001, shortly after he had purchased the property with his partners. Mr. McCabe stated that he had seen the UST, it was approximately 500 gallon capacity, and was in very good condition. The UST had been installed only two years prior (in 1999). Mr. McCabe did not recall who performed the UST removal, and didn't think that any soil or groundwater testing was completed.

The 1963 USGS map also shows a building present at the location of the Mobil Mart (a.k.a. Middlebury Mobil) property. Information obtained from the Vermont Department of Environmental Conservation (VDEC) files indicates that prior to 1991, the Middlebury Mobil property was operated as a Getty service station by the owner, Lee milt's Petroleum, Inc.

In 1963 Middle Road North did not exist along the west side of the Property, but


© 2007 Page 7

existed along the southern property boundary, extending south .. southeast from its intersection with U.S. Route 7 near Creek Road. A group of ten buildings were present on both sides of Middle Road North immediately south of the intersection with U.S. Route 7 and northwest of the Property. These buildings were part of the former Maple Manor Motel property. The buildings were demolished in 2006 prior to construction of the Middlebury South Village development.

Also shown on the 1963 USGS map is a portion of the existing residential development at Birchard Park and a few residential buildings along U.S. Route 7 to the north of the Property. Notably absent is The Centre (currently the Hannaford's Plaza shopping center} to the east of the Property. Both the American Legion building and District 5 VT rans Middlebury Garage building, located on Creek Road to the west and southwest, respectively, from the Property, existed at that time.

Review of the 1963.-1983 photoinspected USGS map shows the same buildings and development in the vicinity of the Property as described above. With regard to adjacent developed properties, The Centre property, including the McDonald's Restaurant, were probably constructed in early 1980's. When constructed, The Centre shopping center buildings were heated with No. 2 fuel oil stored in several USTs. Five (5) of the USTs were located along the west side of the building. During excavation and removal of these 1,000 .. gallon USTs in May, 2004, subsurface soil and groundwater contamination from No.2 fuel oil was discovered.

Development of the area surrounding the Property continued in the.1980's, 1990's and early 2000's. SFR development expansion occurred to the north of U.S. Route 7 and to the southwest of The Centre property during this period. The Citizen's Bank building and property, to the northwest of the Property, was probably developed sometime in the 1980's. The National Bank of Middlebury branch office, east of the Mobil Mart property, was constructed in 2005. Construction of the MSV property, located west and south of the Property, was started in early 2006 and is ongoing. The MSV property includes mixed use commercial/retail/residential and SFR development.

3.5 Summary of Previous Assessments .. On August 3, 2006, Otter Creek Engineering completed a letter sutnmarizing the installation of soil borings and groundwater wells on the Property, the collection of groundwater quality samples, and their analysis at a laboratory for VOCs. The letter is titled "Well Installation and Water Quality Sampling Sutnmary", and is dated August 3, 2007. Data from this report is included in this Phase II ESA Report

In January, 2007, Otter Creek Engineering, Inc. completed a Phase I ESA of the Property. As part of the Phase I ESA Report, an interview was conducted on June 30, 2006 with Mr .. Cory Foote, Representative, Property Manager and Agent for GLR, LLC. Although several questions from the ASTM Standard Practice E 1528 .. 93


© 2007 Page 8

Transaction Screen Questionnaire were asked, one question pertains to previous assessments conducted at the Property. Specifically, Mr. Foote was asked "Does the owner or occupant of the property have any knowledge of any environmental site assessment of the property or facility that indicated the presence of hazardous substances or petroleum products on, or contamination of, the property or recommended further assessment of the property?". Mr. Foote stated that Phase I ESAs were started by others, but no ESAs have been submitted to the owner or occupant. Otter Creek Engineering, Inc. has found no record of these earlier ESA' s.

4.0 PHASE II ACTIVITIES

4.1 Scope of Assessment .. This Phase II ESA was conducted simultaneously with the Phase I ESA completed in January, 2007. Due to the historical use of the Property by a printing company (Highland Press, during the 1980's and early 1990's), and its current use by a drycleaners (Desabrais Laundry & Dry Cleaning from 1995 to the present), GLR, LLC chose to proceed with a subsurface contaminant investigation. The investigation was conducted to determine whether there is soil and/or groundwater contamination present on the Property associated with past or present uses of printing and/or dry cleaning chemicals.

In this regard, five soil borings were drilled and five groundwater monitoring wells were installed in the borings.

OTTER CREEK CNGINEERING

Following groundwater level monitoring and purging, groundwater quality samples were collected from the monitoring wells and submitted for laboratory analysis of VOCs present in petroleum and dry cleaning products. The chlorinated solvent VOCs PCE and TCE were detected in groundwater from one well, with the PCE level exceeding the Vermont Groundwater Quality Enforcement Standard (GQES). Otter Creek Engineering completed a summary report including the data, findings, conclusions, and a recommendation to conduct an investigation to determine the degree and extent of PCE and TCE groundwater contamination on the Property.

The discovery of PCE and TCE in groundwater on the Property prompted the VDEC, Waste Management Division (WMD), to list the Property as Hazardous Waste Site #2006 .. 3560. Additionally, the WMD required that GLR, LLC conduct an additional site investigation to determine the severity of PCE and TCE contamination.

Otter Creek Engineering conducted a soil vapor survey using shallow soil borings, a PID, and Gore TM passive diffusion soil gas sampling (Gore .. Sorber®) modules, at fifteen (15) locations both within and outside the building. The purpose of the soil vapor survey was to determine area(s) on the Property where chlorinated and petroleum VOCs tnay or may not be present in the subsurface soils. After each shallow soil boring was drilled, the interior was assayed for VOCs using a PID, Gore modules were inserted, the boring was capped, and the modules were left for a week.

GLR, LLC PROPERTY- PHASE II ENVIRONMENTAL SITE ASSESSMENT Otter Creek Engineering, Inc.

Following retrieval of the modules, they were shipped to the Gore Laboratory in Elkton, Maryland. Each sample was analyzed for chlorinated VOCs and petroleum.

Gore compiled and summarized the analytical data, along with site maps showing the mass of compounds detected, in a final summary report included as Appendix C. The data indicate that PCE, other chlorinated VOCs and petroleum fuels, are present in soil gas at the Property.

4.1.1 Supplemental Record Review· ... Records information pertaining to hazardous waste use by Highland Press, a former tenant, was provided on October 16, 2006 by Lyn Metcalf of the Vermont Hazardous Waste Management Division. File information included an August 19, 1985, Notification of Proposed Hazardous Waste Activity form, completed by Kristen Travers, Manager of Highland Press. A copy of the form is included in Appendix A. Ms. Travers' brief written description of the hazardous waste generation and disposal activities noted that: "we purchase, use, & dispose of several developing & fixing chemicals (photographic) & cleaning solvents." A list of chemicals used included "PMT Developer, Ultratech Developer & Fixer, Durographic Activator & Stabilizer, Enco Plate Developer & FPC, and Alcohol & Blanket Wash". The method of waste treatment or disposal was described as: "Waste is flushed down sink drains generally. Fixer is sent out to silver refining company. Wastes are stored in drums (metal & plastic)". A search on the internet of Material Safety Data Sheets (MSDS) for these chemicals indicates the following: "Enco FPC" contains hazardous ingredients listed as "High Boiling Petroleum Spirits"; "Durographic Activator" contains "sodium hydroxide and sodium sulfite"; "Durographic Stabilizer" contains "cyclohexanone, thiocyanic acid and acetic acid"; and "blanket wash" may consist of a variety of chemical ingredients, including "aliphatic petroleum distillates", "mineral spirits", "naphtha", "ethyleneglycol monobutylether", and "perchloroethylene" (PCE).

On May 6, 1988, Mike Nelson of the ANR performed a "Status Determination" inspection of the Highland Press facility with "Bill Hanlon, Owner". A Trip Report and Inspection Checklist were completed and copies are included in Appendix A. In the "Hazardous Waste Streams" report section Mr. Nelson states: "The inkwells of all three presses are cleaned daily. Less than a pound of ink per week is thrown out. Approximately three gallons of photochemicals are dumped down the drain each month. Press clean solvents and waste ink from the rollers is wiped up on rags supplied by Foley's Services of Rutland. Foley's supplies Highland Press with 50 rags per week." Under the "Actions Taken" report section Mr. Nelson states: "A letter was sent to Mr. Hanlon recommending alternative methods of waste photochemical disposaL" Mike Nelson, Environn1ental Technician, sent the letter to Mr. Bill Hanlon on May 19, 1988. A copy of the letter is included in Appendix A. The following was stated in the letter: "I am writing you following the hazardous waste

inspection at Highland Press on May 6, 1988. Dumping waste photochemicals down the drain into the municipal sewer system is not an environmentally sound disposal method. The method is acceptable only after the silver has been extracted."

Based on the finding that Highland Press was a former tenant that operated an offset printing business on the Property from 1982 until about 1992, a telephone interview was conducted with Mr. John McGrath on September 13,2006. Mr. McGrath is a former owner of Highland Press, and operated the small offset printing company. Mr. McGrath provided the following information: "Highland Press held two (2) S ... year leases with Betty Gerow" (the Property owner). When asked whether Highland Press used the chemical tetrachloroethylene (PCE) in their business, Mr. McGrath stated "don't know, don't think so". According to him, Highland Press operated "three (3) printing presses", the "rollers were aluminum", and "all ink was used up in the process". He also stated "there were no waste chemicals" generated at the Property, and that any "excess inks were sent to Essex at the main plant", and that "nothing was disposed of to the ground". There were sinks and toilets, but wastes were not disposed of in the sink, since "no sink disposal of ink ... like oil and water .. would not go down anyway". With regard to chemical storage, Mr. McGrath stated there was "no storage outside of drums or chemicals", "ink and water was used" in the printing process, chemicals used for cleaning the "press wash .. not sure what it was ... it evaporated", and that it was "alcohol .. based or something like that". Additional information provided by Mr. McGrath indicated that Highland Press "insulated and heated the building", and the "entire building floor" was concrete "when he was there".

The information provided above indicates that Highland Press used printing inks, various photochemicals, and solvents at the facility from approximately 1982 through 1992. According to the documents in Appendix A, chemical wastes disposal included:

a. Dumping them down the sink drain where they entered the municipal sewer system;

b. Shipment off .. site for reclaimation of silver;

c. Disposal as commercial waste (thrown out);

d. Laundering rags off ... site by a commercial cleaner.

Although there is no confirmed evidence that Highland Press used the chemical PCE in the printing processes at the Property, or that the chemicals used were disposed of by dumping them onto the ground, the printing industry has historically used PCE.

4.1.2 Conceptual Site Model and Sampling Plan .. A conceptual site model for the Property was developed during site visits and building inspections. Specific parameters for the conceptual model include the following:

a. Soil type(s): 1) Mapped as Vergennes clay, 2 to 6% slopes.

2) Granular fill beneath the building, s concrete slab.

b. Depth to groundwater: 1) Estimated at one (1) foot to three (3) feet below grade.

4.1.3 Chemical Testing Plan .. Chemical contaminants of interest include VOCs in air and groundwater. Therefore, soil samples recovered from the soil borings and groundwater collected from the monitoring wells were analyzed for the following specific chemicals:

a. PCE and its natural degradation breakdown (daughter) products, Trichloroethene (TCE); Dichloroethene (1,1.-DCE, cis.-1,2.-DCE and trans .. 1,2.-DCE); and Vinyl Chloride (VC).

b. Fuel Oil and Gasoline petroleum compounds including Benzene, Toluene, Ethylbenzene and Xylenes (Total BTEX); Trimethylbenzenes (1,2,4.-TMB and 1,3,5.-TMB); Naphthalene; and Methyl .. Tertiary Butyl Ether (MTBE).

c. Other VOCs are included as part of the laboratory analytical methods.

A Thermo Environmental, Inc., Model580B PID with 10.6 electron volt (eV) lamp was also used to field screen soil and air samples for the presence ofVOCs in air. The PID does not discriminate individual VOCs but instead yields the concentration of total VOCs in parts per million (ppm), provided as a real.-time digital reading.

4.1.4 Deviations from the Work Plan .. There were no deviations from the work plan.

4.2 Field Explorations and Methods

4.2.1 Soil Boring Installations .. On July 12, 2006, Otter Creek Engineering directed the installation of five (5) soil borings on.-site using vibratory direct push drilling methods. Kennedy Drilling, LLC of Fitzwilliam, New Hampshire completed the soil boring installations.

The five soil borings were placed at different locations across the Property in order to gather as much information as possible relative to the identified potential sources of contamination (petroleum fuel oil and gasoline and the dry cleaning solvent PCE and its breakdown products) on and adjacent to the Property. Groundwater monitoring wells were installed in each boring after drilling. Locations of the five soil borings/groundwater monitoring wells, labeled as MW.-06 .. 01, .. 02, .. OJ, .. 04, and .-05, are shown on Drawing No.2. The locations are described below:

a. Location MW .-06 .. 01 is at the center of the Property, adjacent to the paved parking areas and in an estimated upgradient location relative to the GLR, LLC building.

b. Location MW.-06 .. 02 is along the eastern property boundary, adjacent to the One Dollar Store building, approximately 85 .. feet west of the existing or forn1er fuel oil UST on the One Dollar Store property, and approximately 100 ..

feet northwest of the gasoline contaminant plume in groundwater at the Middlebury Mobil (a.k.a. Mobil Mart) property.

c. Location MW .. o6 .. 03 is close to the east side of the GLR, LLC building, adjacent to the buried sewer pipe that conveys wastewater from the DLDC clothes washers to the municipal sewer system, and approximately 150 .. feet northwest of the residual fuel oil contamination in soils and groundwater from five (5) former petroleum USTs at The Centre property (a.k.a. Hannaford Plaza or Former A&P/Ames Shopping Center).

d. Location MW .. o6 .. 04 is close to the west side of the GLR, LLC building, approximately 55 .. feet northwest of the DLDC dry cleaning machine.

e. Location MW .. o6 .. 05 is close to the south end of the GLR, LLC building, outside the rear door of the DLDC facility, adjacent to the two DLDC fuel oil ASTs, approximately 45 .. feet southwest of the DLDC dry cleaning machine, and in the area where the drums of liquid starch containing residual PCE are occasionally placed for removal, re .. use and/or disposal by unknown persons.

During drilling, soil samples were collected at 3 .. foot intervals, screened for the presence ofVOCs using a PID and olfactory senses, and descriptively logged. In all soil borings there were no petroleum or solvent odors noticeable, and PID readings were non .. detectable (0.0 ppm).

Review of the groundwater monitoring well logs for MW .. 06 .. 0l, .. 02, .. 03, .. 04, and .. 05 (Appendix D) indicates that subsurface soils/sediments present beneath the Property consist of 0.2 .. feet to 3.5 .. feet of permeable sand and gravel fill atop low permeability silty clay in MW .. 06 .. 01, .. 02, .. 04 and .. o5, and only silty clay in MW .. o6 .. 03. The silty clay is laminated throughout, with occasional thin layers of silt. In MW .. 06 .. 05, the silty clay is present below the fill from a depth of 1.5 .. feet to 6.3 .. feet. Below the silty clay is l .. foot of permeable sandy glacial till with gravel. Deeper advancement of the vibratory core sampler below 7 .3 .. feet was not possible due to refusal on a rock or the top of bedrock.

4.2.2 Groundwater Monitoring Well Installations .. On July 12, 2006, Otter Creek Engineering supervised the installation of five (5) groundwater monitoring wells on the Property. The wells were all installed by Kennedy Drilling, LLC in the drilled soil borings. Four (4) wells (MW .. 06 .. 01, .. 02, .. 03 and .. 04) were installed to a depth of 12 .. feet below grade, and one (1) ·well (MW .. 06 .. 05) was installed to refusal on a rock or top of bedrock at a depth of 7 .) .. feet below grade.

In each boring, a l .. inch diameter PVC monitoring well containing solid riser pipe and slotted well screen, endplug, expansion plug, sand pack, and bentonite seal was installed. Protective, cemented in place, bolt .. down wellboxes were installed. The

locations and elevations [ground elevation, well top of casing (TOC) and groundwater surface] of all five (5) monitoring wells are shown on Drawing No.2. Descriptions of core samples recovered and well construction details are presented in the Well Construction Logs as Appendix D.

On July 13, 2006, the day after the wells were installed, the wells were purged using disposable polyethylene bailers prior to the collection of water quality samples. Later, each well TOC was theodolite surveyed and the data was used to prepare a groundwater contour map showing groundwater elevations and flow direction.

4.2.3 Groundwater Elevation and Well Headspace PID Measurements .. On July 13, 2006, the day following installation of the five (5) monitoring wells, groundwater levels were measured using an electric interface probe capable of detecting the groundwater level and a minimum of 0.01 .. inches of free .. phase LNAPL or DNAPL product. The depth to groundwater (DTGW), groundwater elevation (GWEL), and other data are summarized in Table 1. No free phase LNAPL or DNAPL product was detected in any of the monitoring wells. Additional groundwater level data was collected during_ monitoring events completed on July 31, August 8, and October 3, 12, 17, 19 and 25.

A PID was used to monitor the well headspace for the presence of vapor phase VOCs, and the data is summarized in Table 2. Additional well headspace PID data was collected during monitoring events completed on July 31, August 8, and October 12, 17, 19 and 25, 2006. Review of the PID data shows that vapor phase VOCs were absent (0.0 ppm) in wells MW.-06 .. 01, .. 02, --03 anq .-04. Vapor phase VOCs were detected by PID from the MW.-06 .. 05 well headspace during the six (6) monitoring events after July 13, 2006. VOCs concentrations ranged from 6.6 ppm on August 8 to 16.0 ppm on October 19, 2006.

Review of the July 13, 2006 groundwater level data in Table 1 shows that the depth to groundwater in the'monitoring wells ranged between 1.43 .. feet (MW.-06.-02) and 10.67 .. feet (MW .. 06.-03) below well TOC. A groundwater contour map was not produced from the July 13, 2006 data since the groundwater levels within the low permeability silty clay had not fully equilibrated following well installation. Groundwater quality satnples were collected from the wells that day.

The July 31, 2006 groundwater level monitoring event was completed after an eighteen (18) day groundwater equilibration period. Review of the data in Table 1 shows that the depth to groundwater in the monitoring wells ranged between 1.85 .. feet (MW .. 06.-01) and 6.62 .. feet (MW.-06 .. 05) below well TOC on July 31, 2006. These data were used to generate a groundwater contour map included as Drawing No. 3. The monitoring event completed on October 12, 2006 shows that the depth to groundwater ranged between 1.51 .. feet (MW .. o6 .. o 1) and 6.41 .. feet (MW .. Q6 .. Q5) below well TOC. These data were also used to generate a groundwater contour map

included as Drawing No. 4.

Well MW ~06~05 was dry during the groundwater level monitoring events conducted on August 8 and October 17, 2006. Attempts on October 3, 12, and 19, 2006 to collect a groundwater quality sample from MW .. o6 .. 05, using a disposable bailer, were unsuccessful since there was an insufficient thickness of water in the bottom of the well to fill a portion of the bailer. Following a significant rainfall event, on October 25, 2006 a groundwater thickness of 1.28 .. feet in MW~06~05 allowed collection of a groundwater sample.

4.2.4 Groundwater Flow Direction, Depth to groundwater below each well TOC on July 31, 2006 was used with the established TOC elevations to generate a groundwater contour map (Drawing No.3). Review ofDrawing No.3 shows that the groundwater beneath the GLR, LLC property flows generally toward the south. The groundwater gradient between wells MW .. o6 .. 04 and MW .. 06~05 is moderate at 0.0385.-feet/foot. The ultimate discharge zone for groundwater migrating from the GLR, LLC property is presumed to be the Otter Creek, which is located approximately 1 ,200~feet west~southwest at an elevation approximately 25.-feet lower.

Depth to groundwater data collected from the five (5) monitoring wells on October 12, 2006 was used to generate a groundwater contour map, included as Drawing No. 4, that shows a similar groundwater flow direction (generally to the south) and a slightly steeper gradient, at 0.0400.-feet/foot.

4.2.5 Soil Gas Boring Installations .. A soil gas survey, using the Gore.-Sorber® Modules, was conducted in October, 2006 at the southern portion of the Property in and adjacent to the GLR, LLC building. The purpose of the soil gas survey was to evaluate subsurface soil gas for the presence ofVOCs associated with petroleum fuels and the solvent PCE.

A description by Gore of the Gore--Sorber® Module (a.k.a. Gore TM Module) follows:

"The Gore TM Module is a patented, passive, sorbent .. based sampler, which collects volatile and semi .. volatile compounds present in air, soil and water. The module is constructed of a Gore .. Tex® membrane tube. The membrane is chemically~inert, vapor permeable and waterproof. The membrane has over 80% open area and pore sizes that are 1,000 times larger than the largest semivolatile organic vapor molecule, thus offering virtually no resistance to vapor migration. Engineered adsorbents are housed within the Gore~ T ex® tube. The adsorbents were selected due to their affinity for a broad range of organic compounds while having minimal water vapor uptake. Volatile and semi--volatile compounds present in air, soil gas or water diffuse virtually unimpeded through the membrane to the adsorbent material, while liquid water and soil particles are prevented from contacting the adsorbent. Compounds moving to the inside of the membrane are immediately collected by the adsorbents."


© 2007 Page 17

OTTER CREEK CNGINEERING

"The unique membrane is hydrophobic and excludes liquid water, and does not retard vapor transfer, thus allowing VOC and SVOC vapors to penetrate the module freely and collect on the adsorbent material. This ability to protect the sorbent media from contact with ground and soil pore water, without retarding soil vapor diffusion, facilitates the application of the Gore TM Survey in virtually any geological site condition, while protecting sample integrity."

On October 10, 2006, Otter Creek Engineering drilled fifteen (15) 1.-inch diameter by 32.-inch long soil borings (SB.-1, .. 2, .. 3, .. 4, .. 5, .-6, .. 7, .-8, .. 9, .-10, --11, .. 12, .. 13, .. 14 and .. 15) on the Property, at the locations shown on Drawing No.5. An electric rotary hammer drill with 36 .. inch long steel spiral auger bit was used to drill the borings. The boring locations were chosen based on the presence of underground utility corridors (municipal water and sewer pipes), proximity to petroleum fuel sources (two 275-gallon fuel oil ASTs on the Property, oil.-stained concrete floor in the MDF storage room, residual fuel oil contamination of soils and groundwater on The Centre property to the east, and the presence of a gasoline plume in groundwater and soils on the Mobil Mart property to the east), and proximity to the D LDC dry cleaning machine and PCE use/storage areas.

Eleven (11) soil borings (SB .. 1, .. 5, .. 6, .. 7, .. s, .. 9, .. 10, .-12, .-13, .-14 and .. 15) were drilled outside the building, and four (4) soil borings (SB~2, .. 3, .. 4 and .. 11) were drilled through the concrete floor inside the building. In the DLDC facility boring SB .. 2 was located adjacent to the clothes washers in an existing open hole in the wood floor, SB.-3 was located in front of the dry cleaning machine adjacent to the clothes access door, and SB .. 4 was located between two steam.-powered clothes presses. In the MDF facility boring SB .. 11 was located in the center of the food storage room. After drilling each boring a PID was used to field screen the boring interior for the presence of vapor phase VOCs. A Gore.-Sorber® Module was then inserted into each boring, the boring capped tightly with a cork pounded in place, and the location labeled and marked with ink on the concrete floor or a wire flag outstde of the building.

4.3 Sampling and Chemical Analyses and Methods

4.3.1 Soil Samples .. Soil samples collected from the five (5) soil borings (MW.-06.-01, .-02, .. 03, .. 04 and .-05) during drilling were screened in the field for the presence ofVOCs using a PID and olfactory senses, and descriptively logged. No field PID evidence of VOCs was found. Soil samples were not collected and submitted to a laboratory for chemical analyses.

4.3.2 Groundwater Quality Samples .. Disposable polyethylene bailers were used to collect groundwater quality samples from all five (5) monitoring wells (MW .. 06 .. 01, .-02, .-03, .. 04, and .-05) on July 13, 2006, the day following well installation. Prior to sampling MW .-06.-01, .-02, .-03 and .-05 were purged until no water could be retrieved from the bailer, and MW.-06.-04 was purged of more than three well volumes. Following

groundwater recovery in the wells, the water quality samples were collected, kept chilled, and delivered (on July 14, 2006) along with a trip blank sample and completed chain.-of.-custody form to the Endyne, Inc. Laboratory in Williston, Vermont. All water quality samples were analyzed for dissolved phase VOCs via EPA Method 8260. The July 13, 2006laboratory report is included as Appendix E.

A second groundwater quality sample was collected from MW.-06.-05 on October 25, 2006. Approximately 0.16 gallons of water was purged from the well prior to sample collection. This sample was also kept chilled and delivered on October 2 7, 2006 to the Endyne, Inc. Laboratory, along with a completed chain.-of .. custody form, for VOCs analysis via EPA Method 8260. The October 25, 2006 laboratory report is included as Appendix F.

4.3.3 Gore .. Sorber® Soil Gas Samples .. Within each of the fifteen (15) soil borings, a single Gore.-Sorber® Module was inserted using a stainless steel rod supplied by Gore. Modules for SB.-1 to SB.-15 include modules #513438 through #513452. A Trip Blank module sample (#513453), contained in a sealed glass vial with screw top, was present but kept sealed during all module insertions. A Field Blank module sample ( # 514655), also in a sealed glass vial with screw top, was placed on the concrete floor and opened briefly only during insertion and retrieval of the SB.-3 module. The Field Blank module was not removed from the glass vial container during the insertion and retrieval processes.

A PID was used to screen each soil boring for the presence of V OCs prior to insertion of the Gore TM Module. Detections ofVOCs by PID occurred in SB.-2 (0.6 ppm), SB.-3 (0.8 ppm), SB.-4 (6.0 ppm), SB.-9 (0.2 ppm), SB.-13 (0.8 ppm) and SB.-14 (19.0 ppm).

During the insertion process the bottom of each Gore TM Module was placed to the bottom of the boring. The module top was tied to a nylon string secured to a metal screw eye in a cork plug. The cork plug was pounded into the boring opening to prevent the entrance of atmospheric air into the boring. The modules were left in place for seven (7) days, and retrieved on October 17, 2006.

During module placement on October 10, 2006, all soil borings were moist to dry except for SB.-2, located in front of the clothes washers, which was wet. Steve Noble of DLDC stated that the hole in the wood floor was caused by wet rot from constant washing machine water leakage. When the SB.-2 module (#513440) was retrieved, it was wet. When SB ... 1 was drilled and the module inserted, the soils were moist. , When the SB ... 1 module (#513452) was retrieved, its bottom portion was wet.

A PID was used to screen each soil boring for the presence of V OCs following removal of the cork plug and prior to retrieval of the Gore ™ Module. Detections of VOCs by PID occurred in SB.-2 (0.2 ppm), SB.-3 (1.4 ppm), SB.-4 (46 ppm) and SB ... 14 (42 ppm). All soil borings were then filled to grade with sand, except SB.-2, .. 3, .. 4,

and , 11, which were filled with sand to the bottom of the concrete slab and then plugged and leveled to floor grade with hydraulic cement.

Following retrieval of the Gore .. Sorber® Modules on October 17, 2006, they were packaged and shipped to the Gore Laboratory in Elkton, Maryland for analysis by thermal desorption, gas chromatography, and mass spectroscopy via modified EPA Methods 8260/8270. A final analytical report prepared by Gore including the analytical data, table summaries, and contour maps is presented as Appendix C.

5.0 EVALUATION AND PRESENTATION OF RESULTS

5.1 Subsurface Conditions

5.1.1 Geologic Setting ... The surficial sediments present on the Property are mapped on the Surficial Geologic Map of Vermont (C.G. Doll, 1970) as glaciolacustrine lake bottom sediments, consisting of silt, silty clay, and/or clay containing ice rafted boulders. As stated previously, the soil is mapped as the Vergennes clay, 2 to 6% slopes. Bedrock beneath the site is mapped on the Centennial Geologic Map ofVermont (C.G. Doll, 1961) as the Lower Ordovician age (438 to 456 million years ago) Weybridge member of the Chipman formation, consisting of gray limestone with thin interbeds of sandy limestone Yz to 2 .. inches thick and 1 to 1 Y4'inches apart.

There are no known bedrock outcrops on the GLR, LLC property. However, refusal of the vibratory drilling core in MW .. o6 .. 05 at a depth of 7 .3 .. feet is likely the bedrock surface, based on information provided by Steve Noble ofDLDC. Mr. Noble stated that the bedrock surface was encountered at shallow depths in a. trench excavated during installation in 1995 of the north,south sewer pipe along the east side of the building. Where silty clay was present to the bottom of each boring in MW .. o6 .. 0 1, ... 02, .. 03 and .. 04, in MW .. o6 .. 05 is a one .. foot layer of permeable, sandy glacial till with fine to medium gravel. The sandy layer likely mantles the bedrock surface.

5.1.2 Hydrogeologic Conditions , Groundwater level monitoring from the five (5) monitoring wells indicates that from July 31 through October 25, 2006, the depth to groundwater below each well TOC ranges from 1.51 .. feet in MW .. o6 .. 01 to >6.68 .. feet in MW .. o6 .. 05. The groundwater flow direction is generally south to south .. southeast. The shallow groundwater aquifer across the majority of the Property is located within the silty clay. However, at MW .. o6 .. 05, in the southern corner of the Property, the shallow groundwater aquifer is occasionally within the silty clay or the sandy glacial till layer. These data suggest that there is a vertically downward flow component of groundwater within the shallow aquifer, where shallow groundwater flows laterally but also subvertically downward through the silty clay, into the sandy glacial till, and into the underlying fractured lilnestone bedrock.

5 .1.3 Verification of Conceptual Site Model .. The conceptual site model for the Property was refined and verified through the course of field activities including the installation of soil borings and groundwater monitoring wells, collection of soil quality and groundwater level data, site visits and building inspections. The following describes the conceptual site model.

a. Soiltype(s): 1) Subsurface soils/sediments present beneath the Property consist of 0.2 ..

feet to 3.5--feet of permeable sand and gravel fill atop low permeability silty clay in MW--06--01, --02, --04 and --05, and only silty clay in MW--06--03.

2) The silty clay is laminated throughout, with occasional thin layers of silt.

3) In MW --06--05, the silty clay is present below the fill from a depth of 1.5--feet to 6.3--feet. Below the silty clay is 1--foot of permeable sandy glacial till with gravel, probably mantling the limestone bedrock surface at a depth of 7 .3--feet.

4) Granular crushed stone fill is present beneath the building's concrete slab.

b. Depth to groundwater 1) Groundwater level monitoring from the five (5) monitoring wells

indicates that from July 31 through October 25, 2006, the depth to groundwater below each well TOC ranges from 1.51--feet in MW--06--01 to >6.68--feet in MW.-06.-05.

c. Groundwater flow direction 1) The groundwater flow direction is generally south to south--southeast.

2) The groundwater level data suggest that there is a vertically downward flow component of groundwater within the shallow aquifer, where shallow groundwater flows laterally but also subvertically downward through the silty clay, into the sandy glacial till, and into the underlying fractured limestone bedrock.

d. Potential contaminant sources: DLDC (The Property): 1) A dry cleaning machine (with spill containment pan) contains

approximately 300 gallons of the chlorinated solvent PCE.

2) Two drums containing PCE and PCE .. laden sizing (without spill containn1ent).


© 2007 Page 21

3) A dry cleaning machine wastewater atomizer near the building exhaust fan.

4) The area outside the south end of the DLDC facility where drun1s of liquid starch containing residual PCE are occasionally placed for removal, re.-use and/or disposal by unknown persons.

5) Two (2) 275.-gallon capacity petroleum ASTs containing liquid fuel oil.

Former Highland Press (The Property): 1) Use of printing inks, various photochemicals, and solvents at the

facility from approximately 1982 through 1992. Although not confirmed to have been used by Highland Press on the Property, PCE has historically been used in the printing industry.

2) Chemical wastes disposal included: dumping into the sink where they entered the municipal sewer system; shipment off .. site for reclaimation of silver; disposal as commercial waste (thrown out), and; laundering rags off .. site by a commercial cleaner.

The Centre (a.k.a. Hannaford Plaza or Former A&P/Ames Shopping Center): 1) The presence of residual fuel oil contamination in soils and

groundwater from five (5) former petroleum USTs that could n1igrate west onto the Property.

Middlebury Mobil (a.k.a. Mobil Mart): 1) The presence of a gasoline contaminated groundwater plume that

could migrate along utility trenches and impact adjoining properties.

One Dollar Store: 1) A former fuel oil UST had been located on the north side of the

building and was removed in 2001. Although the UST was characterized as being in good condition, soil and groundwater testing was likely not completed. Therefore, there may be residual fuel oil contaminants present in the soil and/or groundwater that could migrate west onto the Property.

e. Potential contaminant receptors: 1) Granular crushed stone fill beneath the building's concrete slab.

2) Native clay and silty clay soils.

3) Shallow groundwater in the silty clay soils, underlying sandy glacial till and limestone bedrock.

4) Underground municipal water lines and sewer lines in trenches connecting the building with other properties.

5) Surface water in drainage ditches.

6) Indoor air within the building.

f. Contaminant migration routes in the subsurface 1) Cracks in the building's concrete slab.

2) Granular crushed stone fill soils beneath the building's concrete slab floor.

3) Municipal sewer and water utility trenches excavated in the low permeability silty clay soils that are backfilled with more permeable fill soils.

CNGINE:E:RING

5.2.1 Soil Analyses , As stated previously, during drilling soil samples were collected at 3, foot intervals from the five (5) soil borings (MW,06,01, ,02, ,03, ,04 and ,05), field screened for the presence ofVOCs using a PID and olfactory senses, and descriptively logged. As shown in Appendix D, in all soil borings there were no petroleum or solvent odors noticeable, and PID readings were non,detectable (0.0 ppm). A PID was also used to monitor the well headspace (vapor phase from soil gas and groundwater) for the presence ofVOCs (Table 2). Additional well headspace PID data was collected during monitoring events completed on July 31, August 8, and October 12, 17, 19 and 25, 2006. Review of the PID data shows that vapor phase VOCs were absent (0.0 ppm) in wells MW ,06,01, ,02, ,03 and ,04. Vapor phase VOCs were detected by PID from the MW,06,05 well headspace during the six (6) monitoring events after July 13, 2006. VOCs concentrations ranged from 6.6 ppm on August 8 to 16.0 ppm on October 19, 2006.

5.2.2 Groundwater Analyses , Groundwater quality samples were collected fron1 all five (5) monitoring wells (MW ,06,01, ,02, ,03, ,04, and ,05) on July 13, 2006 and were analyzed for dissolved phase VOCs via EPA Method 8260 at the Endyne, Inc. Laboratory. The water quality results are summarized in Table 3, the laboratory reports are included in Appendix E, and the data is shown along with the July 31,

2006 groundwater contour map on Drawing No.3. Review of Table 3 and Drawing No.3 indicates that groundwater from one monitoring well, MW .. 06 .. 05, located near the rear door ofDLDC contained 2,170 parts per billion (ppb) PCE (a.k.a. perchloroethene or· tetrachloroethene) and 3.9 ppb TCE. PCE is the dry cleaning solvent used and stored at the DLDC facility, and TCE is a common natural degradation product of PCE. The State of Vermont Groundwater Quality Enforcement Standard (GQES) for PCE and TCE is 5.0 ppb. The other four (4) monitoring wells (MW .. o6 .. 01, .. 02, --03 and --04) and the trip blank sample did not contain detectable levels ofVOCs. Additionally, there were no "unidentified peaks" (UIP's) present on the chromatograms, indicating that other VOCs not listed on the EPA Method 8260 compound list were not detected.

A second groundwater quality sample was collected from MW --06 .. 05 on October 25, 2006 and also analyzed for VOCs viaEPA Method 8260 at the Endyne, Inc. Laboratory. These results are also summarized in Table 3, and the laboratory reports included in Appendix F. Review of Table 3 indicates that PCE was detected at 371 ppb, above the GQES. TCE was not detected, and there were no UIP's detected. The concentration of PCE has declined significantly as compared to the initial July 13, 2006 water quality sampling results.

5.2.3 Soil Gas Analyses .. Otter Creek Engineering retrieved the Gore .. Sorber® Modules from the soil borings on October 17, 2006, after they were exposed to soil gas for seven (7) days. The samples were packaged and shipped to the Gore Laboratory for chemical analysis of petroleum fuel VOCs and chlorinated VOCs. Gore summarized the data in a Final Report included as Appendix C.

a. Soil Gas Mass .. Review of the Gore Final Report indicates the following VOCs were detected in soil gas samples on the Property [data is presented in mass units of micrograms ( ug) per sorber]. Please note that where the VOC ·was detected, but at a level below the method detection limit (bdl), a less than ( <) sign is used in front of the detection limit (ex. <0.02 ug).

1) PCE (Perchloroethene or Tetrachloroethene), a chlorinated solvent, was detected at ten (10) borings: SB--1 and SB .. 2 ( <0.02 ug), SB .. 11 (0.09 ug), SB .. 9 (0.11 ug), SB.-7 (0.13 ug), SB--2 and SB.-6 (0.18 ug), SB .. 8 (0.30 ug), SB .. 3 (0.99 ug) and SB .. 4 (40.49 ug); and the Field Blank (0.82 ug).

2) TCE (Trichoroethene), a chlorinated solvent breakdown product of PCE, was detected at SB .. 3 ( <0.01 ug) and SB--4 (16.08 ug).

3) 1, 1 .. DCE ( 1, 1 .. Dichloroethene), a chlorinated sol vent breakdown product of PCE and TCE, was detected at SB .. 4 (0.66 ug).

4) t .. 1,2 .. DCE (trans .. 1,2 .. Dichloroethene), a chlorinated solvent breakdown product of PCE and TCE, was detected at SB .. 4 (20.50 ug).

5) c .. 1,2--DCE (cis--1,2--Dichloroethene), a chlorinated solvent breakdown product of PCE and TCE, was detected at SB--3 (0.05 ug) and SB.-4 (63.23 ug).

6) Total Petroleum Hydrocarbons (TPH) were detected at all soil boring locations [range of0.14 ug at SB .. 1 to 10.25 ug at SB--14], the Field Blank (0.22 ug), and the Trip Blank (0.02 ug).

7) BTEX, the combined masses of gasoline range aromatics (petroleum fuels), consisting of one or more of Benzene (BENZ), Toluene (TOL), Ethylbenzene (EtBENZ) and Xylenes (mpXYL and oXYL), were detected at SB.-3 (0.07 ug), SB--5 (0.06 ug), SB.-10 (0.19 ug) and SB.-11 (0.05 ug).

8) C11, C13 & C15, the combined masses of diesel range alkanes (petroleum fuels), consisting of one or more of Undecane ( C 11), Tridecane (C13) and Pentadecane (C15), were detected in all soil boring locations (range of <0.01 ug at SB.-7, .. 8, .. 9, --12, .. 13 and .. 15 to 0.08 ug in SB.-14).

9) TMBs, the combined masses of (petroleum fuels) 1,3,5 .. Trimethylbenzene (1,3,5.-TMB) and 1,2,4..-Trimethybenzene (1,2,4-TMB), were detected at SB.-5 ( <0.01 ug) and SB.-3 (0.2 7 ug).

10) NAPH & 2.-MN, the combined masses of (petroleum fuels) Naphthalene (NAPH) and 2--Methyl Naphthalene (2--MeNAPH) was detected at SB.-3 (0.14 ug).

11) OCT, Octane (petroleum fuel) was detected at SB--3 ( <0.01 ug), SB.-5 (0.01 ug) and SB--11 (0.01 ug).

The Gore Final Report includes four ( 4) contaminant contour maps developed for PCE, cis-- & trans.-1,2--DCE, BTEX, and TPH. Each map shows the module identification numbers and locations, the contaminant mass detected represented by color, the outline of the GLR, LLC building and interior walls and structures, municipal water and sewer utility pipes, and Middle Road North.

Review of the PCE contour map shows that PCE in soil gas was detected beneath the central and southern portions of the building, and outside the building on the west, south and east sides. The greatest mass of PCE detected

GLR, LLC PROPERTY r PHASE II ENVIRONMENTAL SITE ASSESSMENT Otter Creek Engineering, Inc.

© 2007 Page 25

was at SB .. 4, approximately 15 .. feet south of the DLDC dry cleaning machine. The PCE contour map roughly forms an elliptically .. shaped plume.

Included as Drawing No. 6 is a PCE contour map generated by Otter Creek Engineering that shows PCE mass contours of <0.02 ug, 0.10 ug, 1.0 ug, 10 ug and 40 ug. The shape of the contour map is roughly an elliptically .. shaped plume that extends from near the northern end of the building toward the southwest and Middle Road North. Due to the lack of soil gas data southwest of SB .. 6 and SB .. 15 (no modules installed), the <0.02 ug and 0.10 ug contours are open .. ended with question marks, signifying an unknown south .. southwest edge of the plume. Likewise, the northwest edge of the plume also is not

. defined as shown by question marks. The data collected suggest that the PCE soil gas plume may extend off the Property toward the south~southwest and Middle Road North.

Review of the cis .. & trans .. 1,2 .. DCE contour map shows that cis .. & trans .. 1,2 .. DCE in soil gas was detected beneath the southern portion of the building. The greatest mass of cis .. & trans .. l,2 .. DCE detected was at SB .. 4, approximately 15 .. feet south of the DLDC dry cleaning machine. The cis .. & trans .. l,2 .. DCE contour map roughly forms a circular .. shaped plume. Review of the BTEX contour map shows that BTEX in soil gas was detected in a linearly .. oriented east to west zone from SB .. lO to SB .. S, which roughly coincides with the orientation of the 4 .. inch municipal sewer pipe and trench that extends west from the One Dollar Store property. The greatest mass of BTEX detected was at SB .. 1 0.

Review of the TPH contour map shows that TPH in soil gas was detected across the Property. The greatest mass ofTPH was detected at SB .. ll and SB .. 14, within the former MDF food storage area and open lawn area near a large pine tree, respectively. The concrete floor through which SB .. 11 was drilled has oil and waxy stains associated with the use of the propane .. powered forklift. The lawn location where SB .. 14 is located is close to a large pine tree, and the terpenes present in pine needles and roots are a source ofTPH. The two elevated TPH zones show as isolated peaks on the contour map.

b. Estimated Soil Gas Concentrations .. The Gore Final Report also provides estimated soil gas concentrations based on a loam soil type and the PCE mass detected. Estimated concentrations of VOCs detected in soil gas are presented in two tables within the Gore Final Report. Estimated concentrations could not be calculated for SB .. l and SB .. 2, since these Gore Modules were installed and/or retrieved from borings that were groundwater saturated. The soil boring containing the maximum estimated concentrations in soil gas, in parts per billion by volume (ppb V) and in micrograms per cubic n1eter (ug/m3), of the VOCs detected, are listed below:

SB,14 .. TPH 108 ppbV 718.25 ug/m3 .. UNDEC 0.72 ppbV 4.78ug/m3

The estimated concentrations of individual VOCs detected in soil gas ( ug/m3) were compared to the Environmental Protection Agency (EPA) Region III Risk, Based Concentration (RBC) Table- (dated October 25, 2005) for "Ambient Air"~ The RBC's are calculated by EPA toxicologists for approximately 400 chemical compounds to determine the minimum concentration at which human exposure during a lifetime will cause death from cancer to one person in a million people. Although it is understood that the soil gas and its contained VOCs are not directly inhaled by humans, and that any soil gas migration out of the soil particles into the atmosphere or indoor air in a building would be diluted with the surrounding air, the comparison was made to evaluate the general degree of VOCs contamination present in soil gas on the Property.

Not all of the detected VOCs in soil gas are listed in the EPA.Region III RBC Table. Only those VOCs listed in the RBC Table and detected in the soil gas were compared, as shown in the following table.

*Note: Estimated soil gas VOC concentrations exceeding the Ambient Air RBC are shown in BOLD.

Review of the above table indicates that the estimated soil gas concentration ofPCE exceeds the 0.31 ug/m3 Ambient Air RBC in SB .. 3, .. 4, .. 6, .. 7, .. a, .. 9, .. 11 and the Field Blank (F.B.). These soil borings are all located in close proximity to the DLDC dry cleaning machine and PCE liquid storage area, at the southern end of the GLR, LLC building (Drawing No.6). The glass vial containing the F.B. sample was opened when the Gore Module at SB .. 3 (in front of the actively operating dry cleaning machine) was installed and retrieved, suggesting that PCE was present in the indoor ambient air of the building at estimated concentrations that exceed the PCE RBC.

The estimated soil gas concentrations exceed their respective Ambient Air RBC for: TCE in SB-.J and SB .. 4; trans .. l,2 .. DCE in SB .. 4, and; naphthalene (NAPH) in SB .. 3.

The estimated soil gas concentrations did not exceed their respective Ambient Air RBC for: l,l .. DCE in SB .. 4; xylenes (mpoXYL) in SB .. 3, .. s, and .. II; 2 .. methylnaphthalene (2MeNAPH) in SB .. 3; naphthalene (NAPH) in SB .. 5; ethylbenzene (EtBENZ) in SB--5 and --11, and; toluene (TOL) in SB--10.

The Gore Final Report contour map for TPH shows elevated TPH soil gas mass and estimated soil gas concentration at SB--11 (9.38 ug, 98.12 ppbV, 653.22 ug/m3) and at SB--14 (10.25 ug, 107.89 ppbV, 718.25 ug/m3). A possible source for the TPH at SB.-11 may be the oil and waxy stains on the concrete floor within the former MDF food storage area, attributed to use of the propane--powered forklift.

A possible source for the TPH at SB--14 may be explained on page 5 of the Gore Final Report: "Significant levels of terpenes and ketones were observed on Modules 513447 (SB .. 14) and 513447 (SB--12), respectively. Sources of

F.B.

58.59

terpenes are often vegetation, particularly pine trees. Sources of ketones observed are often insects. Significant levels of both terpenes and ketones contribute to values reported for TPH. Mass spectral data suggests that little, if any, of the TPH signal observed on these two modules were from petroleum sources."

At the southern end of the Property near SB .. 14 is a large pine tree. The elevated TPH level is attributed to terpenes (VOCs) from the pine needles and pine roots in the subsurface, and not from petroleum sources.

6.0 DISCUSSION OF FINDINGS AND CONCLUSIONS

0TTE.RCRE.EK LNGINE.E.RING

6.1 Recognized Environmental Conditions .. The data collected during the Phase II ESA indicates that the following are recognized environmental conditions relative to the Property due to the specified findings and conclusions:

a. DLDC Facility (The Property): 1) The groundwater flow direction on the Property is generally south to

south .. southeast, with the shallow groundwater aquifer across the majority of the Property located within the silty clay.

2) However, at MW .. 06 .. 05, in the southern comer of the Property, the shallow groundwater aquifer is occasionally within the silty clay or the thin sandy glacial till layer, suggesting that there is a vertically downward flow component of groundwater within the shallow aquifer, where shallow groundwater flows laterally but also subvertically downward through the silty clay, into the sandy glacial till, and into the underlying fractured limestone bedrock.

3) The presence of 2,170 ppb PCE and 3.9 ppb TCE in a groundwater sample collected from monitoring well MW .. o6 .. 05 on July 13, 2006 indicates that there has been a release of PCE to groundwater on the Property.

4) Some of the released PCE has been reductively dechlorinated to produce the daughter (breakdown) product TCE.

5) The presence ofPCE and its daughter products TCE, 1,1 .. DCE, cis .. 1,2 .. DCE and trans .. I,2 .. DCE insoil gas beneath the building, with the greatest mass and estimated concentrations located in SB .. 4, approximately 15 -feet southwest of the dry cleaning machine and PCE storage area, indicates that a release of PCE has impacted soils on the Property.

6) For comparison purposes only, the estimated soil gas concentrations of


©2007 Page 29

PCE, TCE, and trans.-1,2.-DCE in the soil gas contaminant plume beneath and outside the GLR, LLC building are elevated sufficiently that they exceed the EPA Region III Risk.-Based Concentrations for Ambient Air.

7) The presence and use of a Suprema dry cleaning machine (with spill containment pan) that contains approximately 300 gallons of the chlorinated solvent PCE may be a source of the PCE detected in the subsurface.

8) The former presence of a VIC Model35 drycleaning machine that operated on the Property from 199 5 to 2001, contained PCE storage tanks, but did not have a containment pan under the machine to prevent PCE releases from impacting the concrete floor and environment may be a source of PCE detected in the subsurface.

9) The presence and use of two drums containing PCE and PCE, laden sizing (without spill containment) may be the source of the PCE detected in the subsurface since accidental spillage of PCE while transferring the liquid from the drums into the machine would impact the bare, porous, and cracked (in places) concrete floor, causing eventual PCE impacts to the subsurface soils and/or groundwater.

1 0) The presence and use of a dry cleaning machine wastewater atomizer may be a source of PCE detected in the subsurface, since it sprays filtered wastewater, generated in the dry cleaning machine, into the building atmosphere near an exhaust fan. The fan then blows the misted wastewater and air out the east side of the building. It is not known whether the filtered wastewater contains PCE.

11) The area outside the south end of the DLDC facility (near MW.-06,05) where "empty" drums of liquid starch containing residual PCE are occasionally placed for removal, re,use and/or disposal by unknown persons may be a source of PCE detected in the subsurface since a person taking one of the "empty" drums could dump any residual liquid contents on the ground, thereby unknowingly causing soil and/or groundwater contamination by PCE.

12) Although the July, 2006 groundwater quality data from the monitoring wells installed on the Property did not contain VOCs associated with fuel oil, the two (2) 275,gallon capacity fuel oil ASTs that feed the two fuel oil .. fired boilers are a recognized environmental condition due to the possibility that accidental spillage of fuel oil while refilling the AST s, leakage from the delivery lines to the boilers, or spillage of fuel


© 2007 Page 30

oil while servicing the boilers would impact the building floor and/or soils, and possibly the groundwater on the Property.

b. Former Highland Press (The Property):

OTTER CREEK LNGINE:E:RING

1) Historical use of printing inks, various photochemicals, and solvents at the facility from approximately 1982 through 1992. Research indicates that solvents containing PCE were commonly used in the printing industry, however, there is no conclusive evidence that PCE was used by Highland Press on the Property.

2) Chemical wastes disposal included: dumping into the sink where they entered the municipal sewer system; shipment off .. site for reclaimation of silver; disposal as commercial waste (thrown out), and; laundering rags off .. site by a commercial cleaner.

3) Information provided by Jack McGrath, former owner of Highland Press, and file correspondence obtained from the VDEC, WMD, suggest that the chemical PCE, and its daughter products TCE and DCE, were not used by Highland Press during its tenancy at the Property.

c. The Centre (a.k.a. Hannaford Plaza or Former A&P/Ames Shopping Center): 1) The presence of residual fuel oil contamination in soils and

groundwater from five (5) former petroleum USTs cause this property to be a recognized environmental condition.

2) Residual fuel oil contaminants could impact the soil and/or groundwater on the Property via groundwater migration of contaminants within the sewer trench backfill connecting the northeast .. southwest trending sewer pipe on the One Dollar Store property and the 4 .. inch sewer pipe on the Property.

d. ·Middlebury Mobil (a.k.a. Mobil Mart): 1) The presence of a gasoline contaminated groundwater plume causes

the property to be a recognized environmental condition.

2) The gasoline plume could impact the soil and/or groundwater on the Property via migration of contaminants in groundwater and within the sewer utility trenches connecting the northeast .. southwest trending sewer pipe on the One Dollar Store property and the 4 .. inch sewer pipe on the GLR, LLC Property.

3) Although the July 13, 2006 water quality sampling event did not detect the presence of gasoline .. related VOCs in any of the five (5)


© 2007 Page 31

groundwater monitoring wells, the Property could possibly be impacted by the gasoline plume in the future.

4) The presence in soil gas of the BTEX (gasoline range aromatics) compound toluene at SB.-10; xylenes at SB.-3; and toluene, ethylbenzene and xylenes at SB .. 5 and .. 11; suggest that the source of these contaminants may be from off the Property.

5) The BTEX cotnpounds detected in soil gas may have migrated onto the Property fron1 the Mobil Mart property, following the 4 .. inch sewer pipe trench backfill and connected northeast .. southwest trending sewer pipe trench backfill on the One Dollar Store property.

e. One Dollar Store 1) A former fuel oil UST, located on the north side of the One Dollar

Store building, was removed in 2001. Although characterized by the owner as being in good condition, soil and groundwater testing was not performed.

2) Although it is not known whether residual fuel oil contaminants are present in the soil and/or groundwater, and the July 13, 2006 water quality data from nearby (85 ... feet to the west) groundwater monitoring well MW--06 .. 02 did not show the presence of fuel oil--related VOCs, the possibility exists that any residual fuel oil contaminants associated with the former UST could migrate onto the Property.

6.2 Affected Media .. Media affected by contamination on the Property include the following:

a. Groundwater at monitoring well MW .. 06 .. 05, as evidenced by the detection of the chlorinated solvents PCE and TCE in July, 2006, and the detection of PCE in October, 2006.

b. Soil and soil gas in the PCE, TCE, 1,1.-DCE and 1,2 .. DCE contaminant plume beneath- and outside the building.

c. Soil and soil gas from BTEX and TPH compounds beneath and outside the building.

7.0 RECOMMENDATIONS

Based on the data collected from the Phase I ESA (dated January, 2007), soil borings and well installations, soil sample screening, groundwater quality smnple collection and analysis, soil gas survey and analysis of the Gore TM Modules, and findings and conclusions


© 2007 Page 32

presented above, we recommend the following be completed to further define the degree and extent of PCE soil and groundwater contamination on the Property:

a. Drill seven (7) soil borings and install seven (7) groundwater monitoring wells on the Property, similar to those already installed, at the proposed locations shown on Drawing No. 7. Three borings and wells will be installed inside the GLR, LLC building, of which two would be in the DLDC Facility and one in the former MDF food storage area. All wells will be mounted flush with the ground or concrete floor and secured with a wellbox.

b. While drilling, collect continuous soil cores for PID and olfactory screening, and descriptive logging purposes.

c. Collect one soil sample from each boring.

d. Deliver the soil samples to the Endyne, Inc. Laboratory for analysis via EPA Method 8260 and methanol extraction.

e. Following well installation, complete an elevation survey of each well TOC and adjacent surface grade.

f. Complete a groundwater level and well headspace PID survey of all monitoring wells.

0TTE:R CRE:[.K CNGINE:E:RING

g. Collect groundwater quality samples from all monitoring wells, the drycleaning wastewater tank (after the filters and before the atomizer), and a municipal water sample from an interior sink.

h. Deliver the samples, along with a trip blank, to the Endyne, Inc. Laboratory for analysis via EPA Method 8260.

i. Prepare a summary report including all data collected, groundwater contour and contaminant concentration maps~ conclusions and recommendations for additional work, as warranted.

TRIP REPORT

Participants: Bill Hanlon, owner Mike Nelson, VT ANR

. Date of Inspection: May 6, 1988

Purpose of Inspection: Status Determination

Generator status: small Quantity Generator

EPA ID#: None

Waste Water Treatment System: Municipal Sewer

--------------------~-------------------------------------------

General oescription:

Highland Press is a general commercial printer. The comp~ny does its own typesetting and graphic design as well as offset printing. The six employees operate three simple color offset .. presses (2 A.B. Dick, l Heidelburg), a small darkroom, three ~ platemakers and a binding machine. The company has leased mo~t

'· -of th!! presen~ buil~ng since 1981.

', Hazardous Waste streams:

The inkwells of all three presses are cleaned daily. Less than a pound of ink per week is thrown out. Approximately three gallons of photochemicals are dumped down the drain each month. Press clean solvents and waste ink from the rollers is wiped up on rags supplied by Foley's Services of Rutland. Foley's supplies the Highland Press with so rags per week.

Observations:

About l/3 of the building occupied by Highland Press is used for warehouse space. Half of this space is retained by the owner for storage.

Actions Taken:

A letter was sent to Mr. Hanlon recommending alternative methods of waste photochemical disposal.

Dear Mr. Hanlon:

I am writing you following the hazardous waste inspection at Highland Press on May 6, 1988. Dumping waste photochemicals down the drain into the municipal sewer system is not an _ environmentally sound disposal method. The method is acceptable only after the silver has been extracted. 1

The Agency recommends that the silver be extracted from the : solution on site or that the solutions be saved up and sent out for silver recovery. Several firms handle photochemicals and~ waste plates. The ones that are most commonly used in your a~ea are J.B. Silva co., and Silver Refining co. from Massachusetts

· and ~urlinqt~n Wast~ and Metal Co. i~ Burlington, Vermont.

If you have any questions concerning this letter or the report, please contact me at 244-8702.

Sincerely,

Mike Nelson Environmental Technician

ANALYTICAL PROCEDURES

W .L. Gore & Associates~ Screening Module Laboratory operates under the guidelines of its Quality Assurance Manual, Operating Procedures and Methods. The quality assurance program is consistent with Good Laboratory Practices (GLP) and ISO Guide 25, "General Requirements for the Competence of Calibration and Testing Laboratories", third edition, 1990.

Instrumentation consists of state of the art gas chromatographs equipped with mass selective detectors, coupled with automated thermal desorption units. Sample preparation simply involves cutting the tip off the bottom of the sample module and transferring one or more exposed sorbent containers (sorbers, each containing engineered adsorbents) to a thermal desorption tube for analysis. Sorbers remain clean and protected from dirt, soil, and ground water by the insertion/retrieval cord, and require no further sample preparation.

Analytical Method Quality Assurance: The analytical method employed is a modified EPA method 8260/8270. Before each run sequence, two instrument blanks, a sorber containing 5Jlg BFB (Bromofluorobenzene), and a method blank are analyzed. The BFB mass spectra must meet the criteria set forth in the method before samples can be analyzed. A method blank and a sorber containing BFB are also analyzed after every 30 samples and/or trip blanks. Standards containing the selected target compounds at five calibration levels are analyzed at the beginning of each run. The criterion for each target compound is less than 25o/o RSD (relative standard deviation). If this criterion is not met for any target compound, the analyst has the option of generating second- or third-order standard curves, as appropriate. A second-source reference standard, at a level of 1 Of.lg per target compound, is analyzed after every ten samples and/or trip blanks, and at the end of the run sequence. Positive identification of target compounds is determined by 1) the presence of the target ion and at least two secondary ions; 2) retention time versus reference standard; and, 3) the analyst's judgment.

NOTE: All data have been archived. Any replicate sorbers not used in the initial analysis will be discarded fifteen (15) days from the date of analysis.

Laboratory analysis: thermal desorption, gas chromatography, mass selective detection Instrument ID: # 3 Chemist: DC/JW Compounds/mixtures requested: Al Deviations from Standard Method: None Comments: Soil vapor analytes and abbreviations are tabulated in the Data Table Key (page 6).

DATA TABULATION

#CONTOUR MAPS ENCLOSED: Four (4) B-sized color contour map LIST OF MAPS ENCLOSED:

• Tetrachloroethene (PCE) • cis- & trans-1,2-Dichloroethene (c-, t-1,2-DCE) • Combined Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) • Total Petroleum Hydrocarbons (TPH)

NOTE: All data values presented in Appendix A represent masses of compound(s) desorbed from the GORE™ Modules received and analyzed by W.L. Gore & Associates, Inc., as identified in the Chain of Custody (Appendix A). The measurement traceability and instrument performance are reproducible and accurate for the measurement process documented. Semi-quantitation of the compound mass is based on a five-level standard calibration.

General Comments: • This survey reports soil gas mass levels present in the vapor phase. Vapors are

subject to a variety of attenuation factors during migration away from the source concentration to the module. Thus, mass levels reported from the module will often be less than concentrations reported in soil and groundwater matrix data. In most instances, the soil gas masses reported on the modules compare favorably with concentrations reported in the soil or groundwater (e.g., where soil gas levels are reported at greater levels relative to other sampled locations on the site, matrix data should reveal the same pattern, and vice versa). However, due to a variety of factors, a perfect comparison between matrix data and soil gas levels can rarely be achieved.

• Soil gas signals reported by this method cannot be identified specifically to soil adsorbed, groundwater, and/or free-product contamination. The soil gas signal reported from each module can evolve from all of these sources. Differentiation between soil and groundwater contamination can only be achieved with prior knowledge of the site history (i.e., the site is known to have groundwater contamination only).

• QAJQC trip blank modules were provided to document potential exposures that were not part of the soil gas signal of interest (i.e., impact during module shipment, installation and retrieval, and storage). The trip blanks are identically manufactured and packaged soil gas modules to those modules placed in the subsurface. However, the trip blanks remain unopened during all phases of the soil gas survey. Levels reported on the trip blanks may indicate potential impact to n1odules other than the contaminant source of interest.

• Stacked total ion chromatograms (TICs) are included in Appendix A. The six-digit serial number of each module is incorporated into the TIC identification (e.g.: 123456S.D represents module #123456).

Page 4 of 6


GORETM Surveys- Final Report • Unresolved peak envelopes (UPEs) are represented as a series of compound peaks

clustered together around a central gas chromatograph elution time in the total ion chromatogram. Typically, UPEs are indicative of complex fluid mixtures that are present in the subsurface. LTPEs observed early in the chromatogram are considered to indicate the presence of more volatile fluids, while UPEs observed later in the chromatogram may indicate the presence of less volatile fluids. Multiple UPEs may indicate the presence of multiple complex fluids.

Project Specific Comments: • The minimum (gray) contour level, for each mapped analyte or group ofanalytes,

was set at the maximum trip or method blank level observed or the method detection limit, whichever was greater. When target compounds are summed together (i.e., cis& trans- I, 2-DCE), the contour minimum is arbitrarily set at 0.02 Jlg or the maximum blank level, whichever is greater. The maximum contour level was set at the maximum value observed.

• Background levels of TPH were detected on the trip blanks and the method blanks. No other compounds were observed on the trip blanks or method blanks. Thus, target analyte levels reported for the field-installed modules that exceed trip and method blank levels, and the analyte method detection limit, are more likely to have originated from on-site sources.

• Tetrachloroethene and TPH were observed on the field blank, 514655. The field blank was opened during installation of module 513438, and then opened again upon retrieval of the module. Field blank values represent potential background levels in1pacting data for 513438 and may not represent potential impact to any other field installed module.

• The mapped spatial patterns for tetrachloroethene and cis- & trans-1,2-dichloroethene indicated partially defmed soil gas plumes with the highest level observed at module 513439. Elevated levels ofTPH were observed throughout the survey area. Spatial patterns observed for BTEX indicated highest levels in the soil gas at module number 513451 and partial plume delineation.

• Significant levels ofterpenes and ketones were observed on Modules 513447 and 513449, respectively. Sources ofterpenes are often vegetation, particularly pine trees. Sources of the ketones observed are often insects. Significant levels ofboth terpenes and ketones contribute to values reported for TPH. Mass spectral data suggests that very little, if any, of the TPH signal observed on these two modules were from petroleum sources.

• Data was reported in units of mass desorbed from modules in units of micrograms (J..lg) and as estimated soil gas concentrations in units of parts per billion volume (ppbV) and micrograms per cubic meter (J..lg/m3

). All three data tables are included in Appendix A along with a summary of the procedure used to estimate the soil gas concentrations. Soil properties used in the calculations were based on loam soil. Soil input parameters were taken fron1 Table G-4 ofthe US EPA Draft Guidance on Evaluating the Vapor Intrusion to Indoor Air from Groundwater and Soil (2004).

GORE TM Surveys - Final Report

• Two modules, 513440 and -452, were noted as having been deployed or found upon retrieval in standing water. Since the mechanism for mass transfer to the adsorbent is different for soil and water, values for these two modules were not included in the estimated soil gas concentration data table.

• If the objective of the soil gas survey was to delineate the nature and extent of the contamination, then additional soil gas sampling is recommended in those areas where the color contours appear to extend into unsampled areas. Subsequent sampling events can be combined with the data from this event and mapped together to provide greater coverage.

GORE™ SURVEYS ENVIRONMENTAL SITE ASSESSMENT

FOCUSING YOUR REMEDIATION EFFORTS.

Vapor Concentration Calculations

Vapor concentration data from the GORE™ Module, are derived from existing ASTM 1, MDHS2 and

other accepted and approved methods, which were developed for passive, sorbent-based, diffusion samplers.

Air: flg/m3 = Mass/[( Sampling Rate/1 000 Lt/m3)(Exposure Time)]

Soil Gas: flg/m3 Mass/[(Sampling Rate/1 OOO)(Exposure Time)]/(Soil Effectiveness Factor)

Mass= GC/MS measured mass from the Module (Jlg)

Sampling Rate= liters per hour (L/hr) of contaminated air collected by the Module

Exposure Time= time Module is exposed to contaminated air (hr)

Soil Effectiveness Factor (E) = corrects for soil porosity and moisture content

Sampling Rate determinations were made by measuring the mass uptake of the GORE™ Module over time in a chamber of known concentration. Modules were placed in a sample chamber equipped with sample ports where air of known concentrations was delivered into the chamber. The mass uptake was observed with time. As long as the mass levels are below the adsorbent saturation level, mass uptake is linear. The slope (mass/time) from each linear concentration curve divided by the known or measured concentration yields the sampling rate. The sampling rate has been determined for several petroleum and chlorinated compounds. Where directly measured sampling rates are not yet available, a model based on the physical charact~ristics of measured contaminates is used to predict the sampling rates of other similar compounds in the target analyte list.

The Mass of the target compounds are derived by desorbing the Module and analyzing the sample via gas chromatography and mass spectroscopy (GC/MS) following modified EPA methods 8260/8270 or T0-17. The mass is reported in units of micrograms.

Soil effectiveness factors (E) is applied to the sampling rate to correct for lower potential flow through the pores of the soil, accounting for physical limitations that can retard the vapor migration process, e.g., low porosity soils and moisture in the vadose zone pore space. This compound specific factor is equal to the ratio of the effective diffusion of the compound to the molecular diffusivity of the compound in air. The effective diffusivity in air, Deff is calculated using the Millington & Quirk 3 model for flow through porous soils where Deff = Dair8413

( 1-£H2o) 1013 .

E = Deff/Dair = 8413(1-£H2o) 1013

8 is the soil porosity and £H2o is the fraction of pores filled with water. For best results, use the soil properties that are measured in the soil volume that is effectively sampled by the module during the exposure time.
