Fire Chief Salem Fire Department 48 Lafayette Street Salem, MA 01970 RE: Gibbs Service Station #00856 295 Derby Street Salem, Massachusetts Dear Sir: Hydro-Environmental Technologies, Inc. (HETI) is conducting an Environmental Site Assessment on behalf of BP Oil Company at the above-referenced site. In order to conduct a subsurface investigation to sample ground water quality, HETI is planning to install six monitoring wells at the site. The Salem Conservation Commission has determined that the drilling operations would take place in a resource area, as defined by the Wetlands Protection Act. The Conservation Commission approved the drilling operations contingent upon several conditions. One of the conditions imposed by the Conservation Commission is that the Salem Fire Department is to be informed of the scope of intent of the drilling operations and the date the operations are scheduled to occur. The drilling operations to install monitoring wells are scheduled to occur at the site on October 15, 1991. The drilling will be performed using a truck-mounted Acker AD II hollow-stem auger drilling rig. For each well, a borehole approximately 11 inches in diameter will be extended to a depth of approximately 12 feet below grade. A well constructed of four-inch diameter PVC pipe will be inserted in the borehole. The open space around the well will be backfilled to the surface, and a roadbox will be cemented in place, flush with the surface. A schematic diagram of a typical monitoring well is attached. All soils brought up during drilling will be screened in the field with a photoionization detector (PID) using headspace methods. Contaminated soil will be stored in bolted 55-gallon drums clearly labeled "Hazardous Waste" . Said drums shall not remain on the site for more than thirty (30) days.

Refer to the attached sketch map for proposed well locations. For each well a truck-mounted Acker AD II drilling rig will advance a borehole approximately 8 . 5 inches in diameter to a depth of approximately 15 feet below grade. A monitoring well constructed of four-inch diameter slotted PVC pipe will be inserted in the borehole. The open space around the well will be filled with clean silica sand. A one-foot thick bentonite seal will be then placed approximately one-foot above the screened interval, and the remainder of the boring will be backfilled with drill cuttings. A locking roadbox will be cemented at the surface. A schematic diagram of a typical monitoring well is attached. Soil samples will be collected at approximate five-foot depth intervals during drilling using methods outlined in ASTM D 1586-84. All samples will be screened on-site with a photoionization detector for the presence of volatile aromatics using headspace methods. All contaminated soils, if any, will be placed in 55-gallon drums clearly labeled "Hazardous Waste" and stored outside the buffer zone of the wetlands. The contaminated soils, if any, will be removed from the site at a future date by a licensed hazardous waste hauler. 31O CNfR: DEPARTMENT OF ENVIRONMENTAL PItOl'ECTION 10.99:- Forms - i Form 1 DEP File No. Q (TO be provided by DEP) Commonwealth cnylo of Massachusetts Aaoman: Request for a Determination of Applicability .

(HETI) has prepared a ' Phase 1 Limited Site Assessment of the Gibbs Service Station located at 295 Derby Street in Salem, Massachusetts. The ' purposes of this assessment were to identify releases of hazardous materials or oil to the environment and to satisfy the requirements of BP Oil Company. ' 1. 1 Previous Work Four monitoring wells, numbered MW-1 to MW-4 , were installed by ' HETI on December 26, 1989. HETI personnel surveyed the ' monitoring wells and sampled the ground water in the wells on January 3 , 1990. One of these wells, MW-1, could not be sampled ' due to the presence of 0. 31 feet of free product on the water table. The total dissolved BTEX concentration in ground water ' samples collected from the other monitoring wells on January 3 , ' 1990 ranged from 1,980 parts per billion (ppb) to 26, 400 ppb. During the period from February 8 to February 12 , 1990. HETI ' provided dewatering services in conjunction with underground storage tank excavation and removal operations at the site. One ' soil sample was collected for laboratory analysis from the soil ' excavated from the gas tank pit on February 6, 1990. Total BTEX NYDRQ ENVI NMENTAL TECH ES,INC. 1 2 1 (benzene, toluene, ethylbenzene, and xylenes) concentrations in the sample were 49, 620 ppb. The soil sample also contained 406 ' parts per million (ppm) total petroleum hydrocarbons, 1, 230 ppm oil and grease contaminants, and 840 ppb of PCB's. All existing monitoring wells were destroyed or paved over during construction operations conducted from February to April, 1990. 2 . 0 PROJECT SCOPE 1 ' The objectives of the investigation were to: ' 1. Determine if oil or hazardous materials had been stored on the site in the past, or had been stored or released on adjacent ' properties where they could have migrated to the site; ' 2 . Determine if oil or hazardous materials are stored on the ' site at the present time; 3 . Identify releases of oil or hazardous materials to the ' environment, and, if present, make a preliminary determination of the extent and magnitude of contamination. To accomplish these objectives, HETI performed the following ' tasks: 1 ' NYDRQ MENTAL ENiAL '1ECIIN LOGIES,INC. 3 1 I. A detailed site inspection was conducted on April 29, 1991. 2 . Background research was performed at Salem municipal offices on April 29, 1991. 3 . File review was performed at the Department of Environmental ' Protection offices in Woburn, Massachusetts on May 7, 1991. ' 4 . Seven borings were performed on the site on October 15, ' 1991. Four-inch diameter monitoring wells were installed in the six borings that intersected the water table. 5. Sediment samples obtained during drilling were screened for ' the presence of volatile organic contaminants with a Thermo- Environmental Instruments, Inc. OVM 580B photoionization detector. 6. Ground water samples were obtained from the six monitoring wells on October 18, 1991 and were analyzed by a state-certified ' laboratory for the presence of volatile and halogenated organic pollutants using EPA methods 601 and 602 . 7 . The locations and elevations of the monitoring wells were ' surveyed on October 18, 1991. Depth to water readings were ' HYD ENVI NiAL TEQIN LOGIES,INC. 4 taken on October 18, 1991 and a water table topography map was ' constructed. ' 3. 0 SITE DESCRIPTION Site Location: 295 Derby Street ' Salem, Massachusetts County: Middlesex Site Owner: BP Oil Company ' 9040 Roswell Rd. Atlanta, Georgia Assessor's Map and Lot Number: Map 34 , Lot 442 Zoning: Central Development USGS Topographic Quadrangle: Salem, MA (7 . 5 X 7 . 5 minute) ' The site is presently occupied by a Gibbs service station. The site is a roughly rectangular parcel of land located at 295 Derby Street in Salem, Massachusetts. The site is utilized for ' gasoline sales only. No commercial automotive repair is performed at the site. The total area of the site is ' approximately 17, 617 square feet. The northern half of the station is paved with asphalt. This ' area contains four gasoline pumps located on two islands. The HYD ENVIRNWMAL UCNN WMES,INC. 5 underground gasoline storage tanks are located near the western ' border of the site, west of the service station building. The ' building is located approximately in the center of the site. This building is of one story cinder block construction, and measures approximately 35 feet by 20 feet. The building is divided into an office area, a storage space, and two restrooms. Utility lines known to be buried beneath the site include water and sewer connections which are tied into mains running east- west beneath Derby Street. The site's water service enters via an underground line to the north of the station building. The ' site's electric service enters the station from an underground line of unknown location. A sewer leaves the building from the ' restrooms located on the western side of the building and runs ' north to the sewer line beneath Derby Street. The southern half of the site is unpaved and does not appear to be heavily utilized. This area is covered with a one-inch thick layer of gravel resting on polyethylene sheeting. Refer to Figure 2 for ' details of the property layout. ' The station appeared to be fairly clean and well maintained at ' the time the inspection was conducted on April 29, 1991. A pile of gravel and irregular concrete debris, probably debris remaining from the construction in February, 1990, was located ' at the western edge of the site in the unpaved area. All free 1 ' HYDRO ENVIRONMENTAL TEOIN LOGIES,INC. 6 refuse at the site is disposed in a dumpster at the western edge ' of the site. Except for the construction debris noted above, there was no free refuse observed at the time of inspection. 1 ' 3. 1 Underground Storage Tanks ' Three underground gasoline tanks were removed from the site on February 2 and February 3, 1990. Soils excavated during the ' tank removal were screened with a photoionization detector. The ' photoionization detector gave readings ranging from 78 parts per million (ppm) to 300 ppm. The soils removed during the ' excavation were stockpiled on the unpaved (southern) portion of the site. HETI personnel visited the site on April 12 , 1990 to screen the stockpiled soils with a photoionization detector and ' collect additional samples for laboratory analysis. The photoionization meter values from the stockpiled soil ranged ' from 16 ppm to 300 ppm. Two soil samples collected for total petroleum hydrocarbon (TPH) analysis contained 305 ppm and 534 ' ppm TPH. Two soil samples collected for analysis for volatile ' organic analysis by EPA method 8240 did not contain contaminants in concentrations above the method detection limits. Approximately 1, 500 tons (1,100 cubic yards) of contaminated ' soil was removed from the site on April 12, 1990 by E. J. Smith ' Trucking, Inc. of Dorchester, Massachusetts. All soil was taken ' HYDRO ENVI NMENTAL TEOI LOGIES,INC. 7 to Continental Paving of Londonderry, New Hampshire to be ' recycled into asphalt. Presently, there are three 10, 000-gallon fiberglass underground ' gasoline storage tanks on-site, according to records at the Salem Fire Department. These tanks are located to the west of ' the station building. Replacement underground gasoline storage tanks were installed in February, 1990, in the same approximate ' location as the previous tank area. Refer to Section 1. 1 for ' more details regarding tank installation. ' No fuel oil or waste oil tanks were identified at the site during the site inspection and the review of municipal records. ' 3.2 Hazardous Materials And Hazardous Waste ' The only hazardous materials and petroleum products known to be stored on-site presently or in the past are petroleum fuels, and ' small quantities for retail sale of automotive fluids, motor ' oil, lubricants, and antifreeze. Commercial automotive repair work is not performed at the site. Degreasing solvents are not ' stored or used on-site. No hazardous wastes are generated on- site. Waste oil is not stored on-site. ' NYD ; ENVI N NTAL 1ECNN LOGIES,INC. 8 3.3 Usage of the Surrounding Properties The site and surrounding area are zoned as Central Development. ' A multi-family residential area exists approximately 500 feet to ' the southwest. An industrial area is located approximately 600 feet south of the site. The nearest residential two-family ' zoned area is located approximately 1, 200 feet east of the site. ' The property adjacent to the western side of the site along Derby Street is occupied by a Goodyear Tire store and a parking lot. Along- Derby Street to the west are a paint and wallpaper store and a restaurant. Along Derby Street to the east are a Texaco service station and a parking lot, both of which abut the ' site to the east, a travel agency, and a vegetable market. ' Directly across Derby Street from the site is a cemetery. Adjacent to the cemetery to the east is an unoccupied retail ' store and a parking lot. Adjacent to the cemetery to the west are a restaurant and a parking lot.

' NYD ENVIRONMENTAL TE�IN L061ES,INC. 9 4. 0 MUNICIPAL RESEARCH AND SITE HISTORY The following Salem municipal officials were contacted on April 29, 1991 regarding the site: Assessor's Office: Margaret Gauthier Engineering Department: Robert Gates Building Department: Joanne Hamel Fire Department: Inspector La Pointe ' Conservation Commission: Kathleen Winn Water Department: James D. Santo The earliest municipal record reviewed is a town map dated 1897 . ' This map indicated that the site was utilized in 1897 as a 1 lumberyard operated by F. A. Langmaid Company. This lumberyard contained wood and coal sheds, and was adjacent to coal sheds ' operated by the R. C. Manning Company. The next town map reviewed, dated April, 1915, indicated that the site was still ' used for lumber storage. This map also indicated that there was ' an auto service station and filling station located at 285-287 Derby Street. This parcel of land is presently occupied by a ' Texaco service station. The 1915 map also indicated that there were auto service and filling stations located at 271 Derby ' Street (approximately 600 feet east of the Gibbs site) , 274-282 ' Derby Street (approximately 200 feet northeast of the present 1 EKV RQ ENVI 1�1TAL TE®IN - LOGIEs INC. 10 Gibbs site) , and 249 Derby Street (approximately 700 feet east ' of the present Gibbs site) . According to the Assessors Office, ' in 1954 the site was used for lumber storage, under the ownership of Frank A. Langmaid Trust for John Langmaid, Jr. ' According to records at the Assessor's Office, the parcels of land at 289-313 Derby Street, including the site, were ' transferred in 1964 to John T. Spinelli. In 1971 the property at 295 Derby Street was purchased by Kernco, Inc. BP Oil Company purchased the property from Kernco, Inc. in 1981. The ' site is presently owned by BP Oil Company. No other information regarding site history was available from the municipal records. Records provided by the Building Department indicate that a ' permit to build a gas station at the site was first granted on ' November 6, 1970. On April 15, 1975, a permit was granted to erect a canopy with a foundation over the pump islands. The ' Building Department did not have any records indicating or suggesting that automotive repair work was ever performed at the ' site.

The files for the three remaining locations were examined. i 1 ' NYDR ENVIRONMENTAL TECIIN LOGIES,INC. 13 5.2 Site Files The file for the Gibbs service station located at 295 Derby Street contained several documents relating to the replacement of underground storage tanks at the site, including a Oil/ Hazardous Material Spill/Release Report from the DEP dated December 12 , 1989. This report documented a spill of an unknown amount of virgin gasoline and soil contamination related to a 1 leaking underground storage tank. Free product was observed on the water table when the tops of the tanks were uncovered. Another Oil/Hazardous Material Spill/Release Report dated February 2 , 1990 was contained in the files. This report indicated that as one of the underground storage tanks was ' pumped dry, the tide rose, and the tank floated up to the surface. DEP engineer D. Ottenheimer gave on-site short term measures approval to remove the tanks, replace the tanks, and ' remove as much contaminated soil as necessary. The file contained a letter dated February 6, 1990, from the United States Environmental Protection Agency. This letter was an ' NPDES permit exclusion related to tank emplacement and dewatering activities. The file contained a letter dated April 9, 1990 from Kathleen M. Winn of the Salem Conservation Commission. This letter stated that the commission voted to allow an emergency tank removal at the Gibbs service station. The soil stockpiled from this operation remained on-site, and HYDR001 ENVIRONMENTAL TECHNOLOGIES,INC. 14 the Commission required it to be removed. The file contained a tbill of lading dated April 12, 1990. This stated that E. J. ' Smith Trucking, Inc. of 259 Quincy Street in Dorchester, Massachusetts transported approximately 1,500 tons (1, 100 yards) of contaminated soil to be recycled at Continental Paving in Londonderry, New Hampshire. No further information was ' available in the file. The file for the property at 285 Derby Street indicated that a small amount of air compressor fluid leaked from a 10 gallon drum on March 11, 1985. Speedy-Dry pellets were used to clean the spill. The file indicated that there was probably no subsurface contamination, and no subsurface study was ' undertaken. No further information was available in the file. The file for 287 Derby Street, the Texaco station adjacent to ' the Gibbs site, indicated that soil contamination around an underground gasoline storage tank was observed when the tank was removed. Soil samples taken from around the tank gave HNu meter ' readings between 100 ppm and 120 ppm. The file reported that the tank exhibited obvious signs of leakage, but no free product ' was observed during the excavation. Another underground gasoline storage tank removed from the site exhibited no signs of leakage, but soil samples collected from the excavation gave ' HNu meter readings between 20 ppm and 40 ppm. The file also HYD ' TECN LOGIES,INC. 15 indicated that a 500-gallon fuel oil tank and a 1, 000 gallon ' waste oil tank exhibited corrosion and sludge leakage upon ' removal. Soils screened from the excavation gave HNu meter readings between 50 ppm and 75 ppm. The file reported soil ' contamination and free product were observed in the fuel and waste oil tank excavations. The file did not indicate the ' quantity of, if any, soils were removed from the site. The file reported that minor benzene and toluene contamination was detected in ground water samples collected from the monitoring ' wells at the property. No further information was available in the files. 5.3 Spills Database ' The December 30, 1989 Spills Database was examined. Six spills were documented in the vicinity of the Gibbs site. The Gibbs site was listed as spill #N-89-2079 . This spill referred to contaminated water and soil encountered during the underground storage tank removal at the site in December, 1989. On ' January 21, 1982 Hamblett and Hayes Co. spilled approximately 4 , 000 gallons of aluminum sulfate into the South River Canal. No spill number was assigned to this incident.

' 5.4 Salem Files ' The Salem Miscellaneous Oil Spills files, Salem Miscellaneous ' Hazardous Materials Spills files, and Salem Miscellaneous Town files were examined. Five incidents in the vicinity of the ' subject site were included in the files. The files contained a ' Gasoline/Oil Spill Report dated February 15, 1984. This report ' NYDRQ ENVIR . NNIENTAL ' iECNN LOGIES,INC. 17 indicated that an unknown quantity of gasoline was spilled into ' the South River from an unknown source. The report stated that ' the discharge to the South River had ceased and the source of the contamination was not identified. This incident was ' documented in a memo from Mary Bester of the DEP to Paul Anderson of the DEP dated February 17, 1984 . The memo stated ' that on February 15, 1984 , Mary Bester responded to a complaint from Captain Gaugin of the Salem Fire Department regarding an oil sheen in the South River. The United States Coast Guard contracted Jet Line, Inc. to deploy a sorbent boom in the river. On February 16, 1984 representatives from the Salem Department ' of Public Works and the DEP opened storm drains and manholes in the area of the spill. No detectable oil was observed during ' these operations. The report indicated that all pollution ' equipment has been removed on February 17, 1984 . The memo indicated that the EPA was continuing the investigation. The files contained a Gasoline/Oil Spill Report dated June 24, 1984 . This report stated that an unknown quantity of gasoline ' was spilled into the South River from an unknown source. The US EPA found a sheen of oil in the South River. Gasoline was found to be discharging intermittently from a catch basin in the storm drain system. No evidence of a surface spill was recorded. The ' report indicated that the case was pending. ' HYD ENVINMENiAL ' TEW LOGIES,INC. 18 The files contained a United Stated Coast Guard report dated ' June, 1985. This report indicated that a minor oil spill in the ' vicinity of the Texaco service station at 289 Derby Street on the South River was observed. A sheen of petroleum was found to ' be discharging through a headwall at the rear of the Texaco station adjacent to the Gibbs station into the South River. ' From 11: 00 to 11:45 am, Marine Safety Officers observed tank tightness tests performed at the Texaco station by Hallberg & Sons Tank Testing, Inc. The 1, 000-gallon diesel underground ' storage tank was determined to be leaking at a rate of 0.5 gallons per hour. No further information regarding this ' incident was available in the files. ' A United States Coast Guard Report dated June, 1985 was contained in the files. This report documented a minor oil spill was observed on the South River in the vicinity of the ' Texaco service station at 289 Derby Street. A sheen of petroleum was observed emanating from beneath the seawall into ' the South River. No reports of product loss were found at the Texaco station. Mr. Norman La Pointe, the Fire Inspector of the City of Salem, requested that line tightness tests be performed ' at the Texaco and Gibbs service stations. At 11: 00 am Marine Safety Officers , from the Coast Guard issued a Letter of ' Notification of Federal Interest to Gibbs Oil Company. 1 ' HYDDA EECHNOL GIES,I ' IENTAL TECi1N LOG1E5,INC. 19 1 Mr. Michael Medoro, a retail assistant at the Gibbs station, ' signed in receipt of the letter. No further information was ' available in the files. ' The files contained a United States Coast Guard report dated July, 1985. This report indicated that a minor oil spill was ' detected in the vicinity of the Texaco service station at 289 ' Derby Street on the South River. The report documented a light oil sheen in the South River in the vicinity of the Texaco station, adjacent to the Gibbs station. The report concluded that the sheen was a product of residual oil contamination left ' in the soil which originated from a leaking underground storage tank. In the report, the Marine Safety Officer indicated that the suspect tank is now empty and scheduled to be replaced. No ' further information regarding this incident was available in the files. 5.5 RCRA List The RCRA Hazardous Waste Generators list dated July 2 , 1990 was examined. No locations in the vicinity of the Gibbs site were ' listed. The Gibbs site was not listed on the RCRA list.

The nearest reservoir indicated on the overlay is the Spring Pond Reservoir, ' located approximately 3 . 5 miles to the southwest of the site. ' 6. 0 SENSITIVE RECEPTORS Depth to ground water at the site is approximately 5 feet below ' grade, according to well gauging conducted by HETI. tHYD ENVIR .NMENTAL TIMIN LOGIES,INC. 21 Information concerning water supplies for the site and surrounding area was obtained from Mr. Robert Gates of the Salem ' Engineering Department. The site and surrounding area receive municipally-supplied water and sewer services via lines ' underneath Derby Street. The Town of Salem obtains all of its water supply from the Massachusetts Water Resources Authority ' (MWRA) , whose reservoirs are located in central Massachusetts, more than 35 miles west of the site. ' The nearest school is approximately 200 feet southwest of the site. The nearest building with a basement is approximately 300 ' feet northwest of the site. Surface water bodies near the site include South River, adjacent to the site, and Salem Harbor, ' located approximately 600 feet east of the site. ' Mr. Gates reported that he was not aware of any private or public wells in the vicinity of the site. A Sensitive Receptor Report is attached as Appendix D. ' 7. 0 TEST BORING AND MONITORING WELL INSTALLATION ' Seven borings, numbered B-1, B-2 , B-3, B-4, B-5, B-5A, and B-6, were performed at the site on October 15, 1991. The borings ' were performed by Technical Drilling Services, Inc. of Clinton, ' Massachusetts using an Acker AD-II hollow-stem auger drilling i HYD ENVIRONMENTAL TECIIN©©LOGIES,INC. 22 rig. Drilling was supervised by HETI geologist Mr. Kevin Trainer. Six four-inch diameter monitoring wells, numbered MW-1 through MW-6, were installed in borings B-1, B-2 , B-3, B-4, B-5A, and B-6, respectively. Refusal was encountered at a depth ' of 3 feet below grade in B-5, and a monitoring well was not installed in that boring. Approximately 1. 5 yards of contaminated sediment were unearthed during drilling operations. The sediment was placed in three ' bolted 55-gallon DOT drums clearly labeled with hazardous waste stickers. All three drums were removed from the site by Zecco, ' Inc. , a licensed hazardous waste hauler, on October 17, 1991 and transported to Cycle Chem, Inc. of Elizabeth, New Jersey to be ' recycled into asphalt. A copy of the Uniform Hazardous Waste Manifest is attached as Appendix E. The six monitoring wells were placed at various locations across the site. MW-1 was placed near the northwest corner of the tank ' area. Monitoring wells MW-2 and MW-3 were placed in the eastern ' portion of the paved area of the site. MW-4 was placed in the northwest corner of the site. Monitoring wells MW-5 and MW-6 were placed in the unpaved portion of the site, between the underground storage tank area and the South River. Locations of ' all the monitoring wells are depicted on Figure 2 , the Site ' Plan. I ENVIVIVITAL ' UMN ES,INC. 23 ' Split-spoon sediment samples were collected from all borings at approximate 5-foot depth increments in accordance with the methods outlined in ASTM D 1586-84 . No split-spoon sample could ' be collected at the 10-foot depth interval in boring B-1 due to a drilling plug stuck in the augers. Grab samples were collected from the soils directly below grade in each boring. Refer to the Boring Logs in Appendix A for sampling details and ' sediment descriptions. ' Monitoring wells were installed in boreholes B-1, B-2, B-3, B-4 , ' B-5A, and B-6. Monitor wells were constructed of four-inch diameter, thread-coupled Schedule 40 PVC materials. Ten-foot ' lengths of machine-slotted, 0.010-inch slot well screen were ' placed across the water table at the bottom of the wells. The well annuli around the screens were packed with clean silica ' sand. The borings were then finished at grade with double- bolted semi-locking roadboxes cemented flush with the surface. ' Well completion details are provided in Appendix B. ' 8. 0 GEOLOGY AND HYDROGEOLOGY 1 Bedrock is not exposed at the site, and was not encountered ' during drilling. According to the Bedrock Geologic Map of ' Massachusetts (Zen, 1983) , the underlying formation is an HYD ENVI IMEN iEC11N LOGIES,INC. 24 unnamed diorite and gabbro complex of proterozoic age. This ' complex is composed of diorite and gabbro with subordinate metavolcanic rocks, and intrusive granite and granodiorite. ' Sediments encountered during drilling consisted mostly of fill. Native clay and silt deposits interpreted to be estuarine or marine sediments were encountered at a depth of approximately 9 feet below grade in boring B-2 . Refer to the Boring Logs in ' Appendix A for individual sediment descriptions. ' The locations and elevations of the monitoring wells were ' surveyed by HETI personnel on October 18, 1991. Elevations were referenced to an arbitrary 100-foot datum located at the western tcorner of the cinder block wall on the west side of the kiosk. ' Measurements of depth to ground water and any free product in the monitoring wells were taken with an MMC interface probe on ' October 18, 1991. This instrument is capable of measuring depth to water and free product to the nearest 0. 01 foot. No free ' product was detected in any monitoring well. Well gauging data is summarized in Table 1. The depth to water readings were coupled with the survey data to produce Figure 4, the Water ' Table Topography Map. The ground water flow direction at the site was determined to be radially away from the area near MW-3 . ' The average ground water gradient at the site was approximately 0. 041. ' NYDRQ ENVIR =NMENiAL TWIN L061ES,INC. 25 1 ' 9 .0 PHOTOIONIZATION METER SCREENING OF SEDIMENT SAMPLES ' Sediment samples collected during drilling were screened for the ' presence of volatile organic contamination with a Thermo Environmental Instruments, Inc. OVM 580B photoionization ' detector using headspace methods. The sediment samples were placed in clean glass jars on the site, sealed with aluminum ' foil, and brought back to HETI's laboratory for analysis. The ' samples were agitated, allowed to equilibrate for several minutes, and agitated again before being screened by inserting ' the wand ,of the OVM through the foil and recording the maximum meter response. The OVM detects volatile organics in air as ' they evolve from the sediment sample. The response of the meter ' is not an accurate determination of the true volatile content of the samples, but instead provides qualitative indications of the ' severity of volatile organic contamination. ' Maximum OVM readings on soil samples from borings B-1, B-2 , B-3 , ' B-4 , B-5, B-5A, and B-6 were 320 parts per million (ppm) , 377 ppm, 4 . 4 ppm, 287 ppm, 132 ppm, 295 ppm, and 135 ppm, ' respectively. OVM values for the specific samples are provided on the boring logs in Appendix A. NYDR ENVIR NMENiAL TECH LOGIES,INC. 26 10. 0 GROUND WATER SAMPLING AND ANALYSIS Ground water samples were collected from the monitoring wells on October 18, 1991 in accordance with the procedure outlined in ' the ground water sampling protocol in Appendix C. All of the samples were chilled and shipped under chain of custody to Groundwater Analytical, Inc. of Buzzards Bay, Massachusetts for analysis for halogenated and aromatic volatile organics by EPA Methods 601 and 602 . Groundwater Analytical, Inc. is state- certified for these analyses. ' The total benzene, toluene, ethylbenzene, and xylene (BTEX) concentrations detected in the water samples from MW-1 through ' MW-6 were 43, 900 parts per billion (ppb) , 1, 889 ppb, 5 ppb, ' 22 , 300 ppb, 8, 960 ppb, and 2, 332 ppb, respectively. Methyl tertiary butyl ether (MTBE) was detected in water samples from ' MW-1, MW-5, and MW-6 at concentrations of 2, 600 ppb, 250 ppb, and 360 ppb. Trace amounts of MTBE were detected in water ' samples from MW-4 . No other contaminants were detected at ' concentrations above the laboratory reporting limit in any of the samples. The analytical results are summarized in Table 2 ' and the laboratory results are attached in Appendix C. An isopleth map illustrating inferred total dissolved BTEX ' concentrations is attached as Figure 5. HYD ENVIIMENTAL TE�IN LOGIES,INC. 27 11.0 CONCLUSIONS 1. The site is an active Gibbs service station located at 295 ' Derby Street in Salem, Massachusetts. The site has been ' utilized as a BP/Gibbs service station for approximately 10 years, and as a service station since 1970. The site appears to ' have been a lumber yard from the 1880's until 1970. 2 . The three 10, 000-gallon double-walled fiberglass gasoline ' underground storage tanks currently utilized on the site were installed in March, 1990. No other tanks are known to exist at the site. ' 3 . Three underground gasoline storage tanks were removed from the site in February, 1990. Sediments sampled during the excavation were screened with an HNu photoionization detector. ' The HNu meter readings ranged from 16 parts per million (ppm) to 300 ppm. A tank excavation dewatering was conducted for the tank installation. Approximately 1, 100 cubic yards of ' contaminated soil were disposed of off site. The existing gasoline underground storage tanks were installed in ' approximately the same area as the former underground storage tanks. HYD ENVI NMENTAL TECH ,INC. 28 4 . Four ground water monitoring wells existed on-site prior to ' the tank replacement in 1990. Approximately 0. 31 feet of immiscible petroleum was observed on the water table in one of ' these wells on January 3 , 1990. ' 5. The site and all surrounding properties are served by a ' municipal water supply. No private or municipal wells are reported in the vicinity of the site. The Town of Salem obtains ' its water from the MWRA, whose reservoirs are located in central ' Massachusetts. The nearest surface water body is the South River, located adjacent to the southern boundary of the site. 6. Department of Environmental Protection records document the ' occurrence of oil sheens on the South River near the site. The ' records also indicate that soil contamination and free product were encountered during tank removal operations at the Texaco ' service station, located at 287 Derby Street, adjacent to the eastern border of the Gibbs site. The Massachusetts Department ' of Environmental Protection has a file on the Gibbs site ' documenting contamination observed during underground storage tank replacement operations performed in February, 1990. 7. Seven borings were performed at the site for this ' investigation. Four-inch diameter monitoring wells were ' installed in the six borings which intersected the water table. ' HYD ENVI TWIlNfMNTAL LOGIES,INC. 29 Samples collected during drilling were screened with an OVM ' photoionization detector. Maximum OVM readings from soil samples from borings B-1, B-2, B-3 , B-4, B-5, B-5A, and B-6 were 320 ppm, 377 ppm, 4 .4 ppm, 287 ppm, 132 ppm, 295 ppm, and ' 135 ppm, respectively. ' 8 . Depth to water at the site is approximately 5 feet below grade. The ground water flow direction was determined to be in a redial pattern extending outward from the area near MW-3 . The average hydraulic gradient at the site was approximately 0. 041. ' 9 . Ground water samples were collected from the six monitoring wells on October 18, 1991 and analyzed by EPA Methods 601 and ' 602 . Total dissolved BTEX concentrations of 43 , 900 ppb, ' 1, 889 ppb, 5 ppb, 22 , 300 ppb, 8, 960 ppb, and 2, 332 ppb were detected in the ground water samples from MW-1 through MW-6, ' respectively.

Using a decontaminated bailer, purge three to five well volumes of water from the well, or purge the well until dry. ' 4. Pour the sample into a precleaned VOA vial equipped with a backed teflon septum and preserved with NaHSO4. Minimize agitation of the sample. Making sure the ' teflon side of the septum faces down, screw the vial tightly closed. 5. Invert the bottle, tap it, and inspect it to ensure no air bubbles are in the vial. 6. Place sample on ice immediately. Keep refrigerated until delivery to lab under chain of custody. ' DECONTAMINATION: ' If a bailer must be used in two wells in one sampling round, the well anticipated to be less contaminated will be sampled first. After sampling the first well, the bailer will be decontaminated by, at a minimum, the following rinse sequence: ' Clean water three rinses Alconox (laboratory detergent) solution three rinses ' Clean water three rinses Distilled water two rinses ' Bailers exposed to free product will never be used to sample for dissolved volatile constituents. 1 508 759 4475 ' 111. 4-91 17 : 14 ;GROUNDWATER ANALYTICAL HYDRO—MA 508 759 4475;# 1/12 t GROUNDWATER Groundwater Analytical, Inc. 228 Main Street ANALYTICAL 6 Bay, 02532 Telephone e(508))759-4441 FAX(508) 769-4475 ' October 31, 1991 Mr. Cedwyn Morgan Hydro-Environmental Technologies, Inc. 54 Nonset Path ' Acton, MA 01720 Dear Cedwyn: ' Enclosed are the Volatile Organic Analyses performed for the BP Gibbs 295 Derby St Salem MA project, sampled on 10-18-91.

This program closely follows the uidance provided by Interim Guidelines and Specifications for Preparing uality Assurance Project Plans, US EPA QAMS-00580 (1980), and Test Methods ' for Evaluating Solid Waste, US EPA SW-846, Third Idition (1986). Quality Control protocols include Standard Operating Procedures (SOPS ' developed for each analytical method. SOPS are derived from US EP methodologies and other established references. Equipment and facility maintenance conform to Good Laboratory Practices (GLPs) . Standards are prepared from commercially obtained reference materials of certified purity, and documented for traceability. Quality Assessment protocols for most organic analyses include a minimum of one calibration standard, one method blank, one matrix spike, and one matrix ' spike duplicate for each sample batch. All samples, standards, blanks, and matrix spikes are spiked with internal standards and surrogate compounds. GC/MS systems are tuned to BFB ion abundance criteria daily, or for each 12 hour operating period, whichever is more frequent. ' Qualit Assessment protocols for most inorganic analyses include a minimum of one calibration standard, one method blank, one sample duplicate, one matrix ' spike and one matrix spike duplicate for each sample batch. Standard curves are derived from one reagent blank and four concentration levels. Curve validity is verified by standard recoveries within plus or minus ten percent of the curve. ' Analytical Batches are used as the basic unit for Quality Assessment. An Analytical Batch is defined as twenty or fewer samples which are analyzed together with the same method sequence and the same lots of reagents and with ' the same manipulations common to each sample within the same time period or in continuous sequential time periods. ' Method Blanks are used to assess the level of contamination present in the analytical system. Method Blanks consist of reagent (analyte-free) water or sand. Method Blanks are taken through all the appropriate steps of an analytical method. A universal blank matrix does not exist for solid samples. ' Sample data is reported on a blank-corrected basis. Matrix Spike/Matrix Spike Duplicates are used to assess accuracy and precision. A Matrix Spike/Matrix Spike Duplicate consists of two replicate samples (or two reagent blanks if sample volumes are inadequate) spiked with a group of target compounds representative of the method analytes. Accuracy is defined as the degree of agreement of a measured value with the true or ' expected value. Percent Recoveries for the Matrix Spike are calculated to assess accuracy. Precision is defined as the degree of mutual agreement of independent measurements as the result of repeated application of the method. Relative Percent Differences between the Matrix Spike and Matrix Spike ' Duplicate are calculated to assess precision. Surrogate Compounds are used to assess the effectiveness of the method in dealing with each sample matrix. Surrogate Compounds are organic compounds which are similar to organic analytes of interest in chemical behavior, but which are not normally found in environmental samples. Percent Recoveries are calculated for each Surrogate Compound. 11- 4-91 17: 14 ;GROUNDWATER ANALYTICAL HYDRO-MA 508 759 4475;4 9/12 ER13UNDWATER ANALYTICAL ' QUALITY ASSURANCE Matrix Spike Recovery and Matrix Spike Duplicate Study Category: EPA Methods 601 and 602 QC Batch: VGA-868 Matrix: Aqueous Units: ug/L ' ANALYTE SPIKED MEASURED ACCURACY PRECISION MS MSO AVG APR Limits RPD Limit 1,1 Dichloroethene 50 47 46 47 93 % 61-145 2 % 14 Benzene 50 51 51 51 102 % 76-127 0 % 11 Trichloroethene 50 53 53 53 106 % 71-120 0 % 14 Toluene 50 53 53 53 106 % 76-125 0 % 13 ' Chlorobenzene 50 53 52 53 105 % 75-130 2 % 13 ' Terms: MS = Matrix Spike; MSD = Matrix Spike Duplicate; AVG = Average; APR = Average Percent Recovery; RPD = Relative Percent Difference.
