THOMAS, U.S. VIRGIN ISLANDS 1.0 INTRODUCTION As specified in the Phase D Remedial Investigation (RI) for the Tutu Wells Site Work Plan (Geraghty & Miller, Inc. 1993), site inspections were conducted at eight facilities in Tutu, St. Thomas, U.S. Virgin Islands (USVI). The site inspections were carried out because results from previous investigations suggested that these sites might have been sources of the petroleum- related compounds and chlorinated volatile organic compounds (VOCs) detected in soil and groundwater in the Tutu Wells Site. The purpose of the site inspections was to gather information regarding the potential for each site as a likely source of contamination, and if so, whether additional field work was warranted to delineate the potential contaminant sources. 2.0 INVESTIGATED SITES The site inspections included examination of the properties for such features as aboveground storage tanks (ASTs), underground storage tanks (USTs), manholes, vents, septic systems, dry wells, oil/water separators, drum storage areas, and oil pits/sumps. Any evidence of on-site waste disposal or releases, such as stained soils or stressed vegetation, were noted during the site inspections. The following eight sites were inspected: • Faith Christian Fellowship Church • Virgin Islands Housing Authority (VIHA) • Curriculum Center (Former LAGA Building) • Tracy Dodd Property • Antilles Auto Parts • U.S. Virgin Islands (USVI) Department of Human Services GERAGHTY & MILLER. INC. TUT °°5 O77<? • Archie's Welding and Auto Body Repair • Unknown Property Formal site inspections were performed at the Faith Christian Fellowship Church, VIHA, Curriculum Center, and Tracy Dodd Property. At the four other properties, site inspections were not conducted because site access could not be obtained, or sufficient information was obtained while performing other RI activities at the property (such as groundwater sampling or water-level measurements during aquifer testing) to assess whether the sites are potential sources. The results of the investigations at each of these sites is described below. Site inspection forms are provided in Attachment A, and relevant correspondence is provided in Attachment B. 2.1 FAITH CHRISTIAN FELLOWSHIP CHURCH The Faith Christian Fellowship Church is located about 500 feet north of the VIHA property and is not shown on any of the study area maps in the Phase II RI Work Plan (Geraghty & Miller 1993). Mr. Brian Turnbull, vice president of the church, and Ms. Essansonne, church administrator, were contacted on April 13, 1994 for information regarding the site. The Faith Christian Fellowship Church purchased the property in 1992 from Storage Facilities, Inc. which was a subsidiary of Island Block Corporation. Mr. Turnbull indicated that the building was used for storage of materials by a hardware store owned by Island Block Corporation. According to Arthur D. Little, Inc. (ADL), Storage Facilities, Inc. purchased the building in 1988 from Ms. Sue Mortimer (Arthur D. Little, Inc. 1993). According to Mr. Turnbull, the West Indies Company originally owned the property and constructed the building to use as a staging ground for the construction of many of the houses in the Tutu area in mid- 1970s. Mr. Turnbull did not know when the West Indies Company ceased their operations at the site. GERAGHTY & MILLER. INC. TUT °°5 O78° 3 In April 1994, approximately two-thirds of the building was used by the Faith Christian Fellowship Church for their meeting area, kitchen, and offices. The other part of the building (on the west side) is leased to D & C Marine, which is engaged in welding and fiberglass repair for boats, and to Better Roots and Fruits, a produce wholesaler. There are no known USTs or septic tanks on the property. The sanitary sewer is connected to the public sewer system. An AST is located on a concrete pad at the southeast corner of the building. Piping from the roof drain is connected to this AST. According to Mr. Turnbull, this tank has always been used for storage of rain water collected on the roof of the building. 2.2 VIRGIN ISLANDS HOUSING AUTHORITY The VIHA is located on Route 38 and is east of the Curriculum Center. A site inspection of the VIHA complex in Tutu was conducted by Geraghty & Miller personnel on March 18, 1994. Ralda Simmonds, legal counsel for the VIHA, was contacted to obtain access to the site. Ms. Simmonds provided information regarding past and present operations, and toured the property with the Geraghty & Miller site inspector. The VIHA property includes a main building, service bay, drum storage shed, storage shed, waste oil storage area, and an unused water purification plant. The VIHA acquired the property from Joseph Sanson in 1978, and began using the upper two floors of the main building for offices in 1981. The VIHA maintenance department moved into the first floor of the building in 1982. Prior to purchase of the facility in 1978 by the VIHA, a car repair shop (Tropical Motors) operated at the site (Arthur D. Little, Inc. 1993). However, there is no further information available about when the shop was operating. Potential sources inspected include a vehicle maintenance area, a former UST, and a waste oil drum storage area. Light maintenance of VIHA vehicles is conducted at the site. A service bay with a pit for accessing the underside of vehicles is located about 50 feet to the west GERAGHTY & MILLER. INC. TUT °°5 07Sl 4 of the main VIHA building. At the time of the visit, the sump in the service bay contained water with a sheen of oil on top. Oil stains are common in the paved area between the service bay and a vehicle maintenance area located on the west side of the main building. A UST is located on the property on the west side of the main building at the entrance to the vehicle maintenance area. The UST is reported to have been used by Tropical Motors. A sample of the contents was taken in 1987 (Geraghty & Miller, Inc. 1993). The contents were sampled and removed in 1989 by Safety Kleen when the UST was abandoned in place. A copy of the analysis of the contents by Safety Kleen is included with the Site Inspection Form in Attachment A. The tank contents were also sampled by Weston/Spill Prevention & Emergency Response (SPER) personnel in 1987. The contents were identified as waste oil (Geraghty & Miller, Inc. 1993). Based on the site information compiled, a soil-gas survey was recommended and performed a part of the Phase n RI. The results of the soil-gas survey showed no detectable VOCs in the soil gas in the vicinity of the UST (see Appendix B). A concrete pad was constructed by the VIHA (date unknown) for storage of drums containing waste oil from the vehicle maintenance operations. The pad does not contain a cover nor any type of berm to contain spills. A drum storage shed is located on the northwest corner of the property and contains about 20 drums of unknown contents. There was no visual evidence of spills or leakage from the drums. ADL collected liquid samples from 11 drums in 1993 (Arthur D. Little, Inc. 1994). Chlorinated VOCs including tetrachloroethene (PCE), 1,1,1- trichloroethane (TCA), and 1,2-dichloroethene (1,2-DCE) were detected in four drum samples. 2.3 CURRICULUM CENTER (FORMER LAGA BUILDING) The Curriculum Center (Former LAGA building) is located on the north side of Route 38, just west of VIHA. Geraghty & Miller conducted a site inspection of the Curriculum Center on March 11 and 18, 1994. Alda Donastorg, Maintenance Supervisor, was contacted by Geraghty & Miller personnel to obtain site access and to identify any individuals that could GERAGHTY ^MILLER. INC. TUT °°5 O78? 5 provide information. Mr. Donastorg indicated that Mr. Lagos, a Curriculum Center employee, was the most knowledgeable individual about the history of operations at the facility. Mr. Lagos was unwilling to discuss the site because of restrictions by the Department of Justice on discussing the matter without prior permission. However, Mr. Lagos said that he knew very little about previous operations. The Curriculum Center is owned by the USVI Department of Education and is used for offices, maintenance work areas, and storage of frozen food and other materials. The Department of Education has occupied the building since 1982. The Panex Company owned the facility from 1979 to 1982, but there is no available information about the nature of their operations. The building was originally constructed by the West Indies Company, Inc. in about 1970, for LAGA Industries, Ltd. (Arthur D. Little, Inc. 1993). LAGA Industries had a textile manufacturing operation in the building from 1971 to 1979. A dry cleaning facility in the northwest corner of the building was a part of the operation. Potential source areas include a drum disposal area at the northwest corner of the building, a former discharge pipe suspected to be associated with dry cleaning operations, a sink that discharges water directly outside the building, and a reported former waste pit. Sampling activities carried out by ADL (1993; 1994) and Geraghty & Miller (1993) suggest that the north side of the Curriculum Center is an area of possible releases of VOCs to the environment. Soil samples taken from that area show elevated levels of PCE, TCE, and 1,2-DCE. A waste pit was reported to have been used by LAGA Industries for storage of fluids from the dry cleaning operation (Arthur D. Little, Inc. 1993). A portion of a 4-inch diameter steel pipe exits the west wall of the building and extends about 20 feet to the north where it has been welded shut. From the location of the pipe, it appears to have been associated with the process fluids from the dry cleaning operation. Another area of concern is along the north wall of the building, where a sink inside the building discharges outside directly to the ground. This sink is used by the Curriculum Center maintenance workers for cleaning materials in an area where paint and chemicals are stored and used. Based on the site inspection information, a soil gas survey was GERAGHTY & MILLER. INC TUT °05 °783 6 recommended and implemented. The soil gas survey showed the presence of chlorinated VOCs in soil gas at several places north and west of the building (see Appendix B). 2.4 TRACY DODD PROPERTY The Tracy Dodd property is located on an unnamed road approximately 200 feet northeast of a five-way intersection of Route 38, Route 382, and the unnamed road. Site inspections of the Tracy Dodd property were conducted on March 27 and April 13, 1994. Geraghty & Miller personnel met with Mr. Dodd on April 13 to discuss present and past uses and owners. Mr. Dodd purchased the property in 1988 from a company (Top Banana) that operated a fruit wholesale company. The property had been vacant for several years prior to the sale. Mr. Dodd did not know any details about uses and ownership of the property prior to the occupancy by Top Banana, other than that the Winter family had owned the property in the 1960s and 1970s and had used the buildings for residences. Title records show that Branko Inc. owned the property briefly in 1978, and MET Motors, Inc. owned the property from 1984 to 1986 (Arthur D. Little, Inc. 1993). Mr. Dodd operated a used car lot at the site from approximately 1988 to 1993. There are currently four buildings and two trailers on the property. At present, all buildings are leased to various tenants. The house on the northeast side of the property is leased to HMS Pest Control Systems, which uses the house and surrounding grounds for office space and storage of chemicals for their domestic pest control business. The building on the northwest side of the property is occupied by Caribbean Sunset, Ltd., Country Radiator and Auto Glass, which is a car radiator repair shop. The building on the west side of the property is used as an equipment storage and vehicle maintenance area for a St. Thomas dive shop. On the south side of the property, Auto Kool, Inc. operates a car air conditioner repair shop. Two trailers are located on the western and central portions of the property; these were leased by Geraghty & Miller for office and storage space during the Phase II RI. GERAGHTY & MILLER. INC. TUT °°5 °784 7 Mr. Dodd did not know of any problems with hazardous material at the site prior to his ownership. During visits to the property, he indicated that he never observed any problems with his tenants' handling or storage of chemicals or waste oils from their operations. During the site inspection conducted on March 27, 1994, 55-gallon drums were observed at the HMS Pest Control Systems property. One drum contained acetone; the contents of the others were unknown. Four apparently empty 55-gallon drums were also observed at the south-central portion of Auto Kool. 2.5 ANTILLES AUTO PARTS Antilles Auto Parts is located on the east side of Route 382, approximately 150 feet north of the intersection with Route 38. A letter dated March 10, 1994 was provided by the property owners, Siegfried and Waltraud Torinus, that provided a history of the site since it was purchased in 1968 (Torinus 1994). This property was purchased from West Indies Enterprises, Inc., a land developer. In 1969, West Indies Enterprises constructed a building and a cistern. The Torinus letter indicated that no hazardous materials were stored on site during this time. In February 1971, a portion of property including the building was leased to Fred Eglin and Seth Larrabee for use as an auto parts retail shop known as E. & L. Auto Parts. According to the Torinus letter, only auto accessories were sold; there was no repair work conducted (Torinus 1994). In March 1978, a new tenant (Tutu Autos) took over the lease and sold auto parts, tires, and batteries. The front portion of the site was paved at this time. Around 1980, Tutu Auto began selling some British cars, which were shipped from Tortola, British Virgin Islands (BVI). According to the Torinus letter, there was reportedly no storage of oil or hazardous materials (Torinus 1994). Tutu Autos was purchased in 1981 by Consolidated Parts/Prime Automotive Warehouse, Inc. The entire Torinus property was leased, and the back portion of the property was paved. GERAGHTYc* MILLER. INC. TUT °°5 °785 O 8 In addition to selling auto parts, repair work was conducted including brake, front-end, and muffler repair. The March 10 letter reported that there was some storage of waste oil drums (Torinus 1994). In May 1988, Thomas Gassett took over the lease. Site activities included selling cars and spare parts, under the business name GS Industries, Inc. Mr. Gassett installed a 10,000- gallon aboveground waste oil UST (Arthur D. Little, Inc. 1993). The property was subleased to Antilles Automotive at an unknown time (between 1991 and 1993). Antilles currently performs automotive repair. According to the March 10, 1994 letter, the waste oil tank was emptied by Safety Kleen on February 9, 1994 (Torinus 1994). The site currently has several vehicle maintenance bays, one reported UST (Arthur D. Little, Inc. 1993), and the waste oil AST. Site access agreements were required from three separate parties at Antilles Auto Parts. These included the owners (Siegfied and Waltraud Torinus), the lessee (Thomas Gassett), and the tenant (Brad Creeger of Antilles Auto Parts). The lessee resisted signing the site access agreement, and the USEPA intervened and required site access for the purpose of sampling the aboveground waste oil tank. Geraghty & Miller collected a sample from the waste oil tank on June 22, 1994. Analysis of this sample showed the presence of petroleum-related compounds, PCE, and TCA. Results are discussed in Section 5.1.4 of the RI Report. Previous sampling was conducted in 1987 by Weston/SPER personnel (Weston/SPER 1988). Water samples were collected from a gutter and a storm drain. Soil and water samples were collected by Camp, Dresser & McKee (CDM) in 1988 and 1989 (Camp, Dresser & McKee Federal Programs Corporation 1989). In addition, a preliminary site assessment was performed in 1989 by NUS Corporation. This assessment indicated that there had been a surface release of waste oil which apparently flowed onto the adjacent Ramsay Motors property (NUS Corporation 1989). ADL conducted a site visit in October 1993 (Arthur D. Little, Inc. 1993) that confirmed the existing information. TUT OO5 O786 GERAGHTY & MILLER. INC. 2.6 USVI DEPARTMENT OF HUMAN SERVICES Difficulty was encountered obtaining site access to the USVI Department of Human Services property at the time the inspections were being conducted. However, a questionnaire requesting site information was submitted to the Department on May 9, 1994 and the Department responded to the questionnaire on May 24, 1994. This form is provided in Attachment B. The information provided indicates that the Department of Human Services purchased the property from Mr. Earle Ottley on November 29, 1989. The property is currently used by the Center for Independent Living, which provides a rehabilitation program for the handicapped, and a Senior Citizen center. Prior to purchase by the Department of Human Services, the property was occupied by Superior Printing and the Senior Citizen Center. This site was referred to by ADL as Classic Printers because they observed a sign on the side of the building (Arthur D. Little, Inc. 1993). The uses and ownership prior to Mr. Ottley are unknown. Based on the responses provided by the Department of Human Services, there are currently no drums, other containers, or storage of hazardous materials. In addition, there have never been any underground or aboveground storage tanks at the site. The Department indicated that hazardous materials may have been used in previous operations conducted by the print shop. There is a cistern and a septic tank on the property. The supply well (Ottley well) could not be located by Geraghty & Miller personnel during the comprehensive groundwater sampling event conducted during the Phase II RI in 1994. A standpipe exists along the south side of the access road near Route 38. This standpipe is believed to have been used to fill water trucks with groundwater pumped from the Ottley well. A site representative (name unknown) indicated that the pipe had not been used for approximately 20 years, and based on visual observation by Geraghty & Miller personnel, it appeared the pipe had not been used recently. It is suspected that the well may have been paved over during construction of the driveway. TUT OOl^i O787 GERAGHTY & MILLER. INC. ' ' 10 2.7 ARCHIE'S WELDING AND AUTO BODY REPAIR A formal site inspection was not performed at Archie's Welding Shop. However, Geraghty & Miller personnel made general observations while collecting water-level measurements from the onsite supply wells during the aquifer test of the Eglin wells. Archie's conducts welding, auto body repair, and painting of automobiles. In addition, some minor mechanical repairs are conducted, such as oil changes. Some concrete staining was observed, and scrap metal was observed throughout the property. ADL personnel toured the facility in October 1993 and observed paints, primers, thinners, and one empty 30-gallon drum of engine degreaser (Arthur D. Little, Inc. 1993). The personnel noted that scrap metal, auto parts, and empty containers were littered throughout the yard. There was no information regarding the waste management systems, septic systems, or underground piping (Arthur D. Little, Inc. 1993). 2.8 UNKNOWN PROPERTY An unknown property was observed approximately 300 feet to the east of Archie's Welding. Based on a review of a 1954 aerial photograph, this property was one of the few buildings in the Tutu area when most of the area was pasture land. Since there was no public water supply available in 1954, this property may have had a supply well. Review on a 1992 aerial photograph indicates the presence of light-colored circular objects, approximately 3 feet in diameter to the south of the building. On inspection during the Phase I RI, it was determined that the property was a residence. Geraghty & Miller personnel interviewed the tenant, who indicated that there was no supply well onsite. No septic tank was observed. The property is owned by Drs. Gorrochateguj and Vigoreaux, who reside elsewhere. GERAGHTY & MILLER. INC. TUT °°5 °788 11 3.0 CONCLUSIONS The conclusions regarding the eight properties are discussed below. 3.1 FAITH CHRISTIAN FELLOWSHIP CHURCH Based on the present information, it does not appear that there are any potential sources at the church property. There are no known USTs or septic tanks, and the sanitary sewer is connected to the public sewer system. The AST reportedly is a water tank. Therefore, no additional work is required. 3.2 VIRGIN ISLANDS HOUSING AUTHORITY (VfflA) Three potential source areas were identified at the VIHA including a former UST, a vehicle maintenance area, and waste oil storage drums. Although oil stained soils indicated the possibility that isolated small spills had occurred at the vehicle maintenance area, no impact to groundwater has been observed. In addition, no VOCs were detected in soil or soil-gas samples collected at the site. Therefore, the VIHA is not considered a potential source area and no additional work is required for delineation. 3.3 CURRICULUM CENTER (FORMER LAGA BUILDING) Potential source areas were identified at the Curriculum Center, including the drum disposal area at the northwest corner of the building, a former discharge pipe and sink located on the north wall of the building, and the reported waste pit north of the building. The constituents of concern are dry cleaning chemicals, such as PCE, and PCE's breakdown (daughter) products, including TCE and DCE. At the northwest corner, there is no direct evidence of a release, and the presence of PCE and its daughter products in the groundwater can not be tied to this area because of other onsite sources. The former waste pit is likely a source of PCE, TCE, and DCE impact to groundwater based on reports by Arthur D. Little (1993) and GERAGHTY^ MILLER. INC. TUT °°5 O78<? O 12 Geraghty & Miller (1993). Additional work may be warranted to delineate the extent of impacted soils in the vicinity of the waste pit and to identify maximum VOC concentrations in soil north of the Curriculum Center building. 3.4 TRACY DODD PROPERTY The Tracy Dodd property has been dismissed as a potential source and no additional work is required. 3.5 ANTILLES AUTO PARTS Based on the investigations and inspections conducted at Antilles Auto Parts, there are no potential sources of impact to groundwater. The waste oil sampling conducted during Phase II of the RI satisfied the data gap regarding waste oil content. 3.6 UNITED STATES VIRGIN ISLANDS DEPARTMENT OF HUMAN SERVICES Based on information provided by the Department of Human Services, there does not appear to be a potential source of impact to groundwater. As such, no additional work is required. 3.7 ARCHIE'S WELDING AND AUTO BODY REPAIR Although departures from good housekeeping practices were observed at Archie's, there is no specific information that suggests that this property is a source of impact to groundwater. 3.8 UNKNOWN PROPERTY The unknown property was determined to be a residence and there are no potential sources. As such, additional investigation at this property is not required. GERAGHTY & MILLER. INC. TUT °°5 079° O 13 4.0 RKFERKNCFS Arthur D. Little, Inc. 1993.

Parcel 214 Anna's Retreat was purchased by Siegfried Torinus and Wahraud Torinus from West Indies Enterprises, Inc. in 1968. West Indies Enterprises, Inc. graded and leveled the ground. Contract 10/20/69 West Indies Enterprises, Inc. constructed the building: a steel building (l a, 1 b| 24'X60' with 16'eave hight, including cistern and slab; 2 end walls, office and parts area with siding. Galvanized steel panels. On July 22, 1970 the place was bulldozed and thereafter the property was fenced and landscaped with Hibiscus hedge around the perimeter. Various Virgin bland trees as Yellow Cedar were planted. There was no storage of any hazardous material. Lease 2/26/71 (2) In 1971 Fred Eglin and Seth Lorrabee leased a portion (124.20'X91.38')of parcel 214 Anna's Retreat with the building. They first finished the interior of the building and then started a small autoparh retail shop: E. & L AUTO PARTS. The back portion of the parcel |40*X91.38') was left to the owner for future developement. It was landscaped. (1968-1981) During the time of this lease there was no repair work done and no service. There was only the sale of auto parts, auto assessories and hardware and there was no contamination possible. The tenants kept the Hibiscus hedge along the fence and around the building well maintained. Lease 3/30/78 (3a, 3b) Lease 9/1/81 Keith Maddox and Ernie Sorrentino of Motorholdings, lid. Tortola, B.V.I. look over the lease from Fred Eglin and Seth Larrabee and operated the small auto parts business: TUTU AUTOS. A new lease was signed with them in 1 978. The business was very small. Tutu Autos sold automotive parts, mostly for foreign cars (Bristish like M.G.), tires and batteries and later (about 1 980) some British oars (as Landrovers) which they shipped over from Tortola. In 1978 the front portion of the parcel was paved (by Meridian Engineering). During the time or Tutu Autos me tenants look special care of the Hibiscus hedge along the fence and of the plants around the building. They kept the place dean. There was no storage of oil or any hazardous material and no pollution. In 1 981 Tutu Autos was purchased by CONSOLIDATED PARTS / Prime Automotive Warehouse, Inc. with Doug Smith and Henry Owens and a new lease was signed. They leased the entire parcel (164^0-X91. 38'). The bock yard was paved and a shade erected. The business was in the first place wholesale and retail of auto parts, and repair work was secondary. They did brake-, frontend-, and muffler-repair, but mainly they sold auto parts, batteries and tires. The used tires were brought to their branch "Tread-Nu Tire Recapping" at Sub-Base (Tel. 77A0700) nor recapping. The property was still landscaped. There were some drums for garbage and some for waste oil as anywhere else in car places on St. Thomas. At our visits we did not see any pollution. TUT uuo OS 21 History of Porcel 214, Estate Anna's Retreat Assignment and Assumption to Lease 5/2/88 (6) In May 1988 Thomas A. GASSETT took over the lease from Consolidated / Prime Automotive Warehouse, Inc. His mayor activities were selling cars and spare parts. His business was named GS Industries, Inc. Gossett installed a 5000 gallon above ground storage lank for waste oil. The Hibiscus was removed. At the present time ANTILLES Automotive is operating at the site and it is visible that they keep the place in good shape. Since the owners of the property are off the Islands for some time of the year (retired and not in best health conditions) they hired an inspector to check the property on a monthly base and to write reports about the conditon of the facj; lity. If necessary he is giving orders for cleanup or repairs to keep the environ- ment dean. He informed us that the last pick-up of waste oil from the tank was done on February 9, 1994 by the SafetyClean-Up Company.

Dear Ms. Kwan: In accordance with the Phase II Remedial Investigation (RI) Work Plan, Tutu Wells Site, St. Thomas, U.S. Virgin Islands (Geraghty & Miller, Inc. 1993a), Geraghty & Miller, Inc., on behalf of the Tutu Environmental Investigation Committee (TEIC), conducted a soil gas survey at the Curriculum Center (former Laga Building) and the Virgin Island Housing Authority (VIHA) properties from February 28 through March 10, 1994. As stated in the work plan, the purpose of the soil gas survey was primarily to provide a screening tool to optimize the locations of proposed new monitoring wells, and to provide a preliminary indication of the potential contaminant source areas. The final location of two shallow new proposed Monitoring Wells, (MW-16 at the Curriculum Center and MW-13 at VIHA) are to be selected after analyzing the results of the soil gas survey. This letter report presents the methodology and results of the soil gas surveys. TUT OOS OS34 201 West Passaic Street. 3rd Floor • Rochelle Park. New Jersey 07662-(201) 909-0700* FAX (201) 909-0567/0568 GERAGHTY & MILLER, INC. METHODOLOGY A Photovac 10S50 portable gas chromatograph (GC) was used to analyze the vapor samples collected at the site. The Photovac 10S50 portable GC is equipped with a photoionization detector (PID) and a CPSil-5 capillary column. The oven temperature was set at 40* Celsius (C). Based on previous data collected at the site, the GC was calibrated with the following compounds: trans-1,2-dichloroethene (trans-1,2-DCE); cis-1,2-dichloroethene (cis-1,2- DCE); benzene; trichloroethene (TCE); toluene; tetrachloroethene (also known as perchloroethene and abbreviated as PCE); meta-xylene; and ortho-xylene. An unbiased 40-foot grid was laid out over the Curriculum Center property and the VIHA property. Some soil gas points were relocated if buildings or concrete pavement presented obstructions. Soil gas survey points were located at each node of the grid. In areas where greater resolution was needed to identify possible contaminant source areas, a 20-foot spacing was employed until the areas of concern were delineated. Soil gas survey sample points were numbered SGC-1 through SGC-46 at the Curriculum Center and SGH-1 through SGH-26 at VIHA, as shown on Figures 1 and 2, respectively. Even though the column temperature is constant, due to the lack of a heated injection port, the temperature of the injection pon and the lines leading to the column changes throughout the day, which changes the retention time of the compounds. Therefore, Geraghty & Miller relies on the chemist, rather than the GC, to identify all compounds. Also, due to software limitations, an internal calibration is based on only one injection. Geraghty & Miller's external calibration is derived from an average of 5 injections which is more accurate. The internal GC library was not used for these reasons; therefore, all peaks were identified by the GC as unknowns. CALIBRATION An air standard was prepared by withdrawing headspace gas from pure stocks of each selected compound using a gas-tight syringe and injection into a 1-liter Tedlar bag previously 'TUT O05 O835 GERAGHTY & MILLER. INC. 3 filled with ultra zero air. The concentration of the compounds in the standard were 2 parts per million by volume (ppmv) of trans-l,2-DCE and cis-l,2-DCE and 5 ppmv for benzene, TCE, toluene, PCE, meta-xylene, and ortho-xylene. This standard was prepared daily. Each morning, the standard was injected into the GC five times. A response factor was calculated for each compound by dividing the standard concentration by the average peak area from the five injections. Detection limits were calculated daily based on instrument response. QUALITY CONTROL Standards were analyzed at a minimum of once every 4 hours and at the end of each day to check for retention time drift. Syringe blanks were analyzed after all standardizations, and equipment blanks were analyzed after running each sample that contained volatile organic compound (VOC) peaks with areas greater than 0.3 millivolt seconds (mv/s). The analysis of syringe blanks and equipment blanks prevents carryover of compounds from one run to the next run. Duplicate sample analyses were conducted every ten samples. Steel rods were rinsed with Micro liquid detergent and distilled water between soil gas points. After each soil gas point where VOCs were detected, probe blanks were analyzed. The probe tube was not reused unless the blank contained no peaks with areas greater than 0.3 mv/s. SAMPLING PROCEDURE A 1 1/2-inch diameter borehole was created in the soil with a slide hammer and solid rod assembly. The depths of the boreholes were approximately 1.5 to 3 feet below land surface. The solid rod was removed and a hollow 1/4-inch diameter stainless steel pipe was inserted with a 1/8-inch Teflon tube contained inside. The Teflon tubing extended above the hollow stainless steel tube; midway down the exposed Teflon tubing was a stainless steel tee through which syringe samples were collected. A nail inserted into the end of the Teflon tubing prevented clogging of the assembly as it was lowered into the borehole. The nail was then disengaged, and the top of the borehole was sealed around the stainless steel pipe with modeling clay. The clay used is reported to be non-toxic and safe for children. A sample of the clay was heated for TUT COS O836 GERAGHTY & MILLER. INC. 4 15 minutes in a VOC vial and the headspace analyzed; no VOCs were detected. The Teflon tubing was attached to a diaphragm pump and the borehole was evacuated. A purging test was performed to determine the correct evacuation time. During the purging test, samples were collected from the stainless steel tee using a gas-tight syringe at 1- minute intervals for 5 minutes. No peaks appeared on the chromatogram of samples collected from Soil Gas Point SGC-1. The study done at Soil Gas Point SGC-3 indicated that all five samples collected during the study had approximately the same concentrations. Therefore, a purging time of 2 minutes was used for all further sampling. The technique used to collect soil gas samples is consistent with that described by Dr. Thomas Spinier, USEPA Region I Lab Director, in his course on soil gas sampling and analysis. The purging time study is designed to indicate at what purging time the area surrounding the probe has its maximum concentration of total VOCs. If the hole was overpumped, the study would show a decreasing concentration of VOCs over time. This recommended purging time study and has proven to be practical and useful at many sites. RESULTS AND INTERPRETATION The soil gas survey results are presented in this section. CURRICULUM CENTER The soil gas sample results for the Curriculum Center are provided in Table 1. Chromatograms for the analyses are included in Appendix A; soil gas sample locations are shown on Figure 1. Soil descriptions for the Curriculum Center from Geraghty & Miller soil boring and monitoring well logs indicated the presence of silty clay (saprolite) varying in thickness from 1.8 feet (at Monitoring Well MW-1) to 10.3 feet (at Soil Boring B-l). Fill placement in the northwest corner of the property has created the thickest soil cover (near Soil Boring B-l). All other boring logs, for locations north and west of the Curriculum Center, TUT OO5 O837 GERAGHTY & MILLER. INC. 5 indicate soil thicknesses equal to or less than 3.7 feet. The soil horizon lies directly over bedrock PCE was detected at 32 locations, at concentrations ranging from 0.06 ppmv (Soil Gas Point SGC-13) to 140 ppmv (Soil Gas Point SGC-43). TCE was detected at eleven locations, at concentrations ranging from 0.03 ppmv (Soil Gas Point SGC-30) to 30 ppmv (Soil Gas Point SGC-43). Cis-l,2-DCE was detected at eight locations, at concentrations ranging from 0.1 ppmv (Soil Gas Point SGC-3) to 5 ppmv (Soil Gas Point SGC-29). Trans-l,2-DCE was detected at six locations at concentrations ranging from 0.04 ppmv (Soil Gas Points SGC-24 and SGC-35) to 0.4 ppmv (SGC-43). Toluene was detected at only one location (Soil Gas Point SGC-37), at a concentration of 0.02 ppmv. Benzene, meta-xylene and ortho-xylene were not detected at any soil sampling locations. The highest concentrations of chlorinated VOCs in soil gas were detected north of the Curriculum Center Building, centered around Soil Gas Point SGC-43 (estimated concentration of approximately 174 ppmv). An area approximately 150 feet long (in an east-west direction) and 90 feet wide (north-south) showed total chlorinated VOCs greater than 1 ppmv (see Figure 1). Two other areas of elevated concentrations of chlorinated VOCs (above 1 ppmv total chlorinated VOCs) were identified at the Curriculum Center. One area is centered at Soil-Gas Point SGC-14 (estimated concentration of 30.1 ppmv). The other area, centered at Soil-Gas Point SGC-04, showed concentrations between 1.0 and 5.0 ppmv. An isolated concentration of 3 ppmv total VOCs was detected at Soil-Gas Survey Point SGC-25. 'TUT O05 0838 GERAGHTY & MILLER. INC. VIRGIN ISLANDS HOUSING AUTHORITY The soil gas survey results for the VIHA property are provided in Table 2. Chromatograms for the analyses are included in Appendix A. Soil gas sample locations are shown on Figure 2. Twenty-six soil gas locations were sampled. VOCs were not detected in any of the soil gas samples collected at the Virgin Islands Housing Authority. According to Ms. Ralda Simmonds, Esq. (VIHA Attorney), an underground storage tank (UST) is located at the southwest corner of the canopy along the west side of the VIHA maintenance building (see Figure 2). RECOMMENDATIONS • Based on the results of the soil gas survey conducted at the Curriculum Center, Geraghty & Miller recommends that proposed shallow Monitoring Well MW-16 be installed at the location of Soil Gas Point SGC-29 (grid coordinates N0340, E0260). The highest concentrations of chlorinated compounds (estimated value of 174.04 ppmv) were detected 30 feet Northeast (upgradient) of this location. The soil sample from this boring with the highest photoionization detector (FID) reading should be collected and analyzed for the Target Compound List (TCL) VOCs. An underground water supply line is located near this location. If this water line interferes with the proposed location for Monitoring Well MW-16, the well will be located downgradient (i.e., southwest), as close as possible to the proposed location. • Since no VOCs were detected in soil gas samples collected at VIHA, proposed shallow Monitoring Well MW-13 should be located within 10 feet of the existing deep Monitoring Well MW-13D; this will form a well pair to provide comparison of shallow and deep groundwater elevations and ground water quality. TUT OO5 0839 GERAGHTY & MILLER. INC. In Geraghty & Miller's Phase n RI proposed Work Plan, the proposed monitoring well at the Curriculum Center was called MW-13 and the monitoring well at VIHA was called MW- 16. These designations have been reversed to be consistent with existing deep Monitoring Well MW-13D at VfflA. Geraghty & Miller, on behalf of the TEIC, would like to request that the USEPA respond promptly to the proposed locations for Monitoring Wells MW-13 and MW-16, so the drilling program can be scheduled accordingly.

Three 4,000-gallon steel USTs, one containing motor fuels were removed from the south end of the Texaco Service Station. Three doubled-walled steel tanks (two 10,000-gallon and one 6,000-gallon capacity tanks) with leak detection systems were installed at the west end of the Texaco service station. USTs were excavated and removed from September 7 to September 9, 1988. USTs were degassed with carbon dioxide prior to removal. Large holes were noted in one of the USTs during an initial investigation. No holes were observed in the other two USTs. During UST removal excavated soils were placed over polyethylene sheeting at the eastern boundary of the site. Excavation depth was approximately 6.5 feet. USTs were transported to the Texaco terminal outside of Charlotte Amalie, St. Thomas. An attempt to collect soil samples from the excavation was made after removal of the USTs. Soil sampling procedure was delayed due to a tropical storm event on September 8 and 9, 1988. Excavation pit was filled with the runoff produced by heavy rain. The soil piles were covered with plastic sheeting. CDM requested that Texaco analyze the water accumulated in the excavation pit and pump out the water prior to infiltration through the excavation walls. See page 3 for footnotes. GERAGHTY & MILLER.

Sampling of Excavation Pit (continued): Water Sampling: Soil Pile Sampling: A tanker truck was not available until September 10, 1988. By this date the water inside the pit had dropped approximately 3 feet. Two 55-gallon drums provided by Texaco were filled with water from the excavation pit for later sampling. A 4,000-gallon tanker truck from the Texaco terminal arrived on September 10, 1988 to remove the water from the excavation pit. Another hurricane advisory was in effect by the evening of September 10, 1988. Operations were shut down and the excavation pit was protected and bermed to keep surface runoff from going inside the excavation. A third 55-gallon drum was filled with the water that had accumulated in the excavation pit. Two tanker trucks were filled to empty the excavation pit. CDM requested soil samples from at least 10 feet downgradient of the excavation area due to flooding of the excavation pit. Three holes were drilled in the concrete pad at the south-southwest portion of the excavation. Borehole depth was not indicated in the letter. Soil samples from the excavation pit were collected on September 13 and 14, 1988: four soil samples were collected from the corners of the excavation pit floor and four soil samples were collected from the center of each wall. Three soil samples were collected in the vicinity of the excavation pit. Three water samples were collected from the 55-gallon drums that were used to store water removed from the excavation pit. One sample per drum was collected. Two soil piles were sampled on September 15, 1988. Three composite samples were collected from the first soil pile. Two composite samples were collected from the second pile. A third pile was generated during excavation for the new tanks installed at the west end of the Texaco service station on September 15, 1988. This soil pile was sampled the following week. One sample was collected from this soil pile. See page 3 for footnotes. GERAGHTY & MILLER. INC. TUT 005 O865 Table C-16. Summary of Tank Excavation Procedures, September 7 to September 16, 1988 at Texaco Service Station, Tutu Wells Site, St. Thomas, U.S. Virgin Islands. Installation of New USTs: Soil Venting System: Air Monitoring: Three new double-walled steel tanks and leak detection systems were installed at the west end of the Texaco service station on September 15, 1988. Excavation procedures began on September 14, 1988. The first 4-feet of soil removed during the excavation was used as backfill for the old tank excavation pit. Remaining soil was piled at the eastern and northern boundaries of the service station. Due to HNU readings obtained from soil samples during field activities of 10 to 15 parts per million (ppm) of total volatile organics, the soil could not be used as landfill. Fill material was utilized to backfill the excavations. The source of this fill material was not indicated in the letter. Soil removed from both excavations was placed over a slotted polyvinyl chloride (PVC) pipe for venting. Air was removed from the pipe with a high vacuum pump system. This system was monitored weekly with an HNU photoionization detector at selected points. Soil samples were scheduled to be collected after completion of the soil venting procedure for final disposition of the soils. An HNU photoionization detector and Draeger tube during field activities. HNU readings during tank excavation ranged between 20-30 ppm with peaks of 80 ppm of total VOCs during soil removal activity. HNu background readings ranged from 0.2 to 1.0 ppm total VOCs. HNu readings above the soil pile surface ranged between 80 to 150 ppm. Breathing zone readings ranged from 5 to 10 ppm. Draeger tubes for benzene levels during UST removal ranged from 1 to 2 ppm during peak activity. HNU readings at the new tanks excavation soil pile were from: 10 to 15 ppm.

Preliminary Site Assessment Report, O'Henry, Inc., St. Thomas, U.S. Virgin Islands, Pedro Panzardi & Associates, October 1989. Not available. Dry cleaning operation: * One dry cleaning unit. * One industrial size washing machine and dryer. Operation started January 2, 1982. Historical purchases of PCE: 17 to 20 drums per year (1.5 to 1.75 gallons per month). No UST at this site. Dry cleaning unit filters, PCE sludge and lint have been disposed at a local dumping site. Total amount of PCE disposed does not exceed 22 gallons per year. At the time of the site reconnaissance and sampling activity, arrangements were made for disposal of PCE at a Safety Kleen facility in Puerto Rico. Reported disposition of PCE residue on-site by an operator. Approximately 36 ft u2 area with a lot of lint residues. In June 1989, soil samples were collected from this area by an inspector. After the inspection, O'Henri removed topsoil and stored it in two containers. No indication of inspector name, sample location, analysis, or laboratory in the report. Pedro Panzardi personnel collected two composite samples on August 23, 1989 (one from each container). Potential of soil and groundwater contamination. Pedro Panzardi proposed soil borings at different locations on the O'Henry to property to collect soil samples for PCE analysis. Composite samples were collected from two containers that were filled with excavated topsoil. Sampling date: August 23, 1989. Sample ID: Station ffl and Station #2.

The samples were obtained from the MW-4D, MW- 6D, MW-11D, and MW-13D Wells, located in St Thomas. U.S. Virgin Islands. The samples were analyzed by detailed thin section petrography. The objective of this study was to characterize the texture and mineralogy of the samples. The sample depths for the respective wells are as follows: Well Depth (feet) MW-4D 59.6-60.0 MW-6D 51.2-51.6 MW-11D 73.5-74.0 MW-13D 65.0-70.0 DISCUSSION The four analyzed bedrock samples are gabbro (well MW-4D), porphyritic basalt (well MW-6D), diorite (well MW-11D), and reworked andesite (well MW-13D). The gabbro and diorite exhibit slightly inequigranular textures with interlocking crystals which average medium grained (1 to 5 millimeters) and fine grained (0.1 to 1 millimeter) sizes, respectively. The inequigranular basalt has a bimodal distribution of the crystal sizes, as does the reworked andesite. The samples appear to be holocrystalline (devoid of glass); however, extensive alteration of the epiclastic andesite from well MW-13D makes the assessment difficult for this sample. Plagioclase is observed to be the predominant primary mineral. Other primary minerals observed in various samples as phenocrysts include pyroxene, magnetite, quartz, hornblende, and apatite. The primary mineralogical composition of samples from the wells of MW-4D, MW- 60, and MW-13D are similar, whereas the sample from MW-11D contains primary quartz, abundant hornblende (both primary and secondary), and primary apatite. Pyroxene is most abundant in the gabbro from MW-4D. Hornblende occurs as both a phenocryst of primary origin and also as a secondary replacement of pyroxene in the samples. Sample MW-13D may also contain rock fragments, although alteration makes this assessment difficult. Alteration in the four samples is variable. The gabbro and diorite from wells MW-4D and MW- 11D are significantly less altered than the porphyritic basalt. Nearly all of the minerals observed in the reworked andesite from MW-13D are secondary replacement minerals. Cement-filled fractures are observed in all four of the samples. Cement-filled and open fractures are particularly abundant in the sample from MW-13D. ANALYTICAL PROCEDURES A Petrographic Study allows for characterization of reservoir rock texture, mineralogy, and porosity. Information about the relationships among rock textures, allochemical/detrital grains, cement and matrix composition, and porosity characteristics are determined from thin section analyses. TUT OO5 1O27 The sample fraction is prepared for thin section analysis by first impregnating the sample with epoxy to augment sample cohesion and to prevent loss of material during grinding. A blue dye is added to the epoxy to highlight the pore spaces. Each sample is mounted on a frosted glass slide and then cut and ground in water to an approximate thickness of 30 microns. Samples containing known water-soluble phases are prepared using odorless kerosene. Prepared thin sections are subsequently stained for calcite (Alizarin Red-S stain), iron-bearing carbonates (potassium femcyanide stain), and potassium feldspar (sodium cobaltinitrate stain) as necessary. The thin sections are analyzed using standard petrographic techniques. The terminology in this report is that of Streckeisen (1978). REFERENCES CITED Streckeisen.

Using Streckeisen's 1979 classification scheme, it is considered to be a gabbro. The predominant constituents are interlocking subhedral plagioclase (seen with abundant polysynthetic twinning; B15.5, J12, F8) and anhedral to subhedral pyroxene (minerals with high birefringence in view; H3, C5). (15X magnification, crossed polarizers) PLATE 1B This photomicrograph, taken at a higher magnification (31X), shows a localized area of finer grained crystals. Magnetite (opaque crystals at H6, G-H9, E10) is observed in this view, along with plagioclase (J2, A14.5) and pyroxene (C9). A cement-filled fracture extended diagonally across the view at C1 to J15. It is filled with pennine, which is a variety of chlorite, and other undifferentiated clay, possibly smecitic or illitic (H13 to K16). Several intersecting fractures are observed in the thin section.

Plagioclase phenocrysts (E8.5, G4.5, J2, K6) float in a very finely crystalline groundmass of tiny plagiodase, altered pyroxene, and undifferentiated microlites and clay. Large amygdules are filled by calcite (E1; stained pink), undifferentiated day (A9, B14-16), chlorite and possibly actinolite (poorly visible here), zeolites (not in view) and chert (K14.5). Small calcite- and day-filled fractures are observed (C1 to C16, K12-E12, E12 to D16). (15X magnification, plane-polarized light) PLATE 2B This photomicrograph shows a partially altered pyroxene phenocryst. Much of the pyroxene in the porphyritic basalt has been altered to secondary minerals. Even at higher magnification, minerals in the groundmass still appear very small. A calcite-filled amygdule is in the upper left of the view.

Minerals in this view include plagioclase (E11, F5), magnetite (G8, K7), and quartz (B3). Hornblende at D-E4 appears dark at this magnification, but is actually green. Much of the hornblende, along with chlorite and pennine, appears to be an alteration product. The green minerals in this view are chlorite and pennine (E7) Calcite fractures intersect at H10. (15X magnification, plane-polarized light) PLATE 3B Another view of the sample shows interlocking crystals similar to those in Plate 3A. The texture of this sample is homogeneous. Several phenocrysts in this view, however, are altered to yellowish day, possibly seriate and/or smectite (C5.5, J9, 013.5).

Intercrystalline clay is abundant. Only trace amounts of the primary minerals, such as plagiodase, remain in this rock. For example, the plagiodase(?) phenocryst at C-F6 is completely altered to secondary minerals, mostly day. (15X magnification, plane-polarized light) PLATE 4B Areas of the sample that are located farthest away from the large caicite-filled fractures appear to be slightly less altered. This view shows altered plagiodase phenocrysts (white crystals) set in a day matrix. The large dark areas (E13, G2, B2) are probably altered mafic phenocrysts. Based on the texture and plagiodase-rich composition, this sample appears to be an epidastic rock derived from an andesite.

THOMAS, U.S. VIRGIN ISLANDS GERAGHTY & MILLER. INC. Tm °°5 jl°4 MEMORANDUM TO: Tutu Wells Site Project File (PR0013.000) and Tom Danahy FROM: Joanna Jasiorkowski DATE: August 26, 1994 RE: Surveying at the Tutu Wells Site, St. Thomas, U.S. Virgin Islands. Several surveying tasks have been performed at the Tutu Wells Site. The main contractor was R. LOPEZ DE AZUA & ASSOC. (RLDA) of Puerto Rico. In 1992, RLDA surveyed the measuring point elevations (ie. top of inner casings), top of outer casings, and ground-surface elevations of the Tutu Phase I Remedial Investigation (RI) monitoring wells installed by Geraghty & Miller, Inc. In September 1993, RLDA was asked to extend the topographic control on the base map to the northeast and the southwest to increase the size of the base map for the Phase II RI Work Plan proposed in December 1993. In February and March of 1994, RLDA surveyed the monitoring wells installed by Blasland, Bouck & Lee, Inc. (designated "DW-" and "SW-") and the monitoring wells installed by GCL (designated "TT-"). In May 1994, RLDA surveyed the Phase II RI monitoring wells installed by Geraghty & Miller, Inc.; the monitoring wells installed by Caribbean Hydro-Tech, Inc. (designated "CHT- "); the monitoring wells installed by Terra Vac, Inc. (designated "KFC-"); the monitoring wells installed by Geo Caribe, Inc. (designated "OHMW-"); and the VIHA-I, VIHA-II, LaPLACE, HARTHMAN WILFRED, EGLIN-I, EGLIN-II, and EGLIN-III supply wells. In July 1994, discrepancies were noticed in the elevations reported at the Monitoring Wells OHMW-1, OHMW-2, OHMW-3, and OHMW-4, and Control Monument 202 at the intersection of Route 38 and Highway 382 with respect to the topographic map. Due to delays associated with the response of RLDA, Brian Moseley and Associates of St. Thomas were contracted to resurvey the monitoring wells designated "OHMW-", and Control Monument 202; and survey the tops of casing at the Church, Steele, and Harvey supply wells. The measuring point elevations at Monitoring Wells OHMW-2 and OHMW-4 changed less than two tenths of a foot, the measuring point elevation at Monitoring Well OHMW- 3 increased by approximately 2.6 feet, and the measuring point at Monitoring Well OHMW- 1 increased by approximately 2.5 feet.

Dear Alberto: We have enclosed two figures illustrating the approximate boundaries of the areas to be extended on the current site base map for the Tutu Wells Site. These figures are provided for your use in procuring a cost estimate from Lopez De Azua & Associates, Inc. The base map should be extended by Lopez De Azua & Associates to the south, southeast and northwest as indicated, and should include cultural features (i.e., buildings, roads and portion of Turpentine Run). * Upon completion of the extended draft base map on or before October IS, 1993, we will review and locate monitoring wells, supply wells and designation on the map for incorporation by our drafting department. It is assumed that base map extension can be made without further aerial or ground work. If sufficient ground control is not available and further aerial or field work will be required, please let us know. We look forward to receiving your response regarding the surveyor's scope of work and cost estimate to complete the work. Sincerely, GERAGHTY & MILLER, INC. i Marie F.

TUT °05 li89 APPENDIX K DATA VALIDATION SUMMARY OF THE PHASE D REMEDIAL INVESTIGATION SOIL RESULTS TUTU WELLS SITE ST. THOMAS, VS. VIRGIN ISLANDS OVERVIEW This report presents the data validation summary for soil samples collected in March and April 1994 for the Phase n Remedial Investigation at the Tutu Wells Site, St. Thomas, U.S. Virgin Islands conducted by Geraghty & Miller, Inc. SAMPLING The samples were collected on 6 days during the period of March 26, 1994 through April 6, 1994 They were delivered to the laboratory using chain-of-custody (COC) procedures in five sample delivery groups (SDGs). Each SDG was assigned a unique laboratory project number. An SDG and sample identification (ID) summary is provided in Table 1. Eight soil samples, one field replicate, one field blank, and four trip blank samples were collected during the sampling period. The field blank sample, identified as FB032694, was collected on the first day of sampling. This field blank is associated with every soil sample collected during the sampling period and was used in the validation of all field samples. Four trip blanks were prepared and shipped with the field samples. The trip blank collected on March 26, 1994 is associated with both SDG 33590 and SDG 33735. SDG 33590 was held for shipment with SDG 33735. This trip blank, identified as TB032694, is associated with the soil samples in the first two SDGs and was used in the validation of MW-18 (12-141), MW-17 (6-81), and MW-15. GERAGHTY & MILLER. INC. TUT oos H9O K-2 A field replicate sample was collected on April 4, 1994 for MW-16 (0-3*) and provided to the laboratory with a blind field identification. The field replicate sample was identified as sample MW-135 (0-3') and is in SDG 33835. Matrix spike (MS) and matrix spike duplicate (MSD) samples were collected for MW-19 (4-6' and 4-8') and analyzed in SDG 33878. For three of the soil samples, the field replicate, the MS, and the MSD samples collected during the sampling period, samples from different borehole depths were provided for the volatile organic compound (VOC) analyses than those provided for all other parameters. The following table summarizes the depths and sample IDs that pertain to the analytical parameters: Soil Boring VQC Analysis Non-VOC Parameters MW-24 MW-16 MW-135 MW-19 MW-19 MS MW-19 MSD MW-24 (4.5-6.51) MW-16 (0-21) MW-135 (0-2f) MW-19 (4-6() MW-19 (4-61) MS MW-19 (4-6') MSD MW-24 (6.5-8.51) MW-16 (0-3') MW-135 (0-3*) MW-19 (4-81) MW-19 (4-81) MS MW-19 (4-8') MSD ANALYSIS The samples were sent to Enseco-Easl in Somerset, New Jersey for analysis of the target compound list (TCL) VOCs, TCL semivolatile organic compounds (SVOCs), target analyte list (TAL) inorganics, total petroleum hydrocarbons (TPHs), and three site-specific VOCs. The site- specific VOCs included the following compounds: methyl-tertiary butyl ether (MTBE); 1,2- dibromoethane (EDB); and n-propylbenzene. GERAGHTY & MILLER, INC. TUT CO5 1191 K-3 The TCL VOCs and TCL SVOCs were analyzed in accordance with the U.S. Environmental Protection Agency (USEPA) Contract Laboratory Program (CLP) methodologies contained in the March 1990 Statement of Work (SOW) for Organics Analysis (USEPA 1990a). The TAL metals and cyanide were analyzed in accordance with the USEPA CLP methodologies contained in the March 1990 SOW for Inorganics Analysis (USEPA 1990b). Analyses for TPHs and site-specific VOCs were conducted in accordance with the methods and requirements of the quality assurance project plan (QAPP) prepared for the remedial investigation at the Tutu Wells Site (Geraghty & Miller, Inc. 1992). VALIDATION All TCL VOCs, TCL SVOCs, TAL metals, and cyanide were validated in accordance with the USEPA Region II data validation guidelines for organic and inorganic analyses performed in accordance with CLP methods for routine analytical services. The guidelines for organics and inorganics are provided in the regional Standard Operating Procedure (SOP) Number HW-6, Revision 8 and in regional SOP Number HW-2, Revision 11, respectively (USEPA 1992a; 1992b). MTBE, EDB, and n-propylbenzene results and quality control criteria were reviewed and validated using the USEPA Region II guidelines for TCL VOCs (USEPA 1992a). Data validation of TPH data was performed according to criteria specified in USEPA Method 4 1 8 1 (USEPA 1983) and in accordance with the following guidelines: • Method and/or reagent blanks - Reported concentration should be less than the quantttation limit. Blanks, including field blanks, associated with field samples were reviewed for contamination. Sample results were evaluated using a five times multiplier of the highest concentration in the associated TPH blank. GERAGHTY & MILLER, INC. TUT 005 1192 K-4 • Precision of duplicates - Acceptable precision was demonstrated by calculation of relative percent difference (RPD) with a limit of 20 percent. For calculated RPD between 20 and 40 percent, all associated sample data for the analytical batch were estimated and qualified with a "J" flag. • Accuracy of matrix spikes - Acceptable accuracy was demonstrated by percent recovery (%R) of MS and MSD in the acceptance window range of 80 to 120 percent. For %R values outside of the 80 to 120 window, but within 50 to ISO %R, associated sample data were qualified as estimated and flagged with a "J." • Accuracy of laboratory control spikes - Acceptable %R of blank spikes was within the window of 80 to 120 percent. For %R values outside of the 80 to 120 window, but within SO to ISO %R, associated sample data in the SDG were qualified as estimated and flagged with a "J." Individual organic and inorganic data review checklists and data assessment narratives were completed for each SDG. This information and any required tables pertaining to the data assessments may be found in Attachments Kl through K10 by SDG number. The information about the data review of MTBE, EDB, n-propylbenzene, and TPH are located in the organic data assessment narratives for each SDG. OVERALL ASSESSMENT Overall, the majority of the data submitted by Enseco-East for analysis are of good quality and demonstrate acceptable precision, accuracy, and completeness. The problems found with the data are discussed below. In the analyses for TPHs, the laboratory failed to report estimated concentrations detected in the method blanks, field blanks, and several field samples. The laboratory was required to report estimated analyte concentrations as specified in the site QAPP (Geraghty & Miller, Inc. GERAGHTY6? MILLER, INC. TUT oos 1193 K-5 1992) This information would allow the data reviewer to evaluate potential sample and blank contamination originating in the field and during analysis. It would also identify target analytes present in concentrations below the CLP contract required quantitation limits and laboratory reporting limits. The TPH data were corrected during the data review in order to evaluate potential sample contamination. In the analyses for the three site-specific VOCs, the laboratory calibrated instruments and quantitated sample concentrations for MTBE only. The laboratory failed to calibrate the instruments for EDB, or n-propylbenzene. In addition, due to an error in the COC record and the project specifications at the laboratory, the laboratory thought that the samples were to be analyzed for dibromomethane instead of EDB. The laboratory narratives for several SDGs did not address the compound discrepancy between EDB and dibromomethane, but noted the lack of calibration for EDB and n-propylbenzene. The laboratory narratives indicated that although calibrations were not performed, the laboratory analysts had reviewed the sample spectra for the presence of EDB and n-propylbenzene and determined that both were not present in any of the samples. In actuality, the laboratory review was for dibromomethane and n-propylbenzene. Since the laboratory review was based on standard reference spectra not associated with the analyses of the samples, the results for dibromomethane and n-propylbenzene are qualitative only and should not be considered quantitative. On this basis, the data for dibromomethane and n- propylbenzene were rejected in the quantitative VOC analyses for all of the field samples and associated blanks. Other data qualifications pertaining to the organic parameters are as follows: • Some data generated for the VOC, SVOC, and TPH analyses have been negated due to blank contamination and estimated due to calibration outliers. • All of the VOC data for SDG 33590 were estimated due to sample condition upon receipt at the laboratory. GERAGHTY & MILLER, INC TUT oos 1194 \ K-6 • The 2,4-dinitrophenol result for MW-15 and the associated SVOC method blank were rejected due to a poor response factor in the calibration analysis. • The results for tetrachloroethene and TPH were estimated in samples MW-16 and MW- 135 because of poor field precision. In the data review of TAL inorganics, the following analytes were qualified because of quality control outliers: • Antimony results were estimated in all field samples and blanks due to calibration deficiencies. • Antimony and chromium results were estimated in all field samples due to MS recoveries. • Cobalt results were estimated in samples MW-19 (4-81), MW-16 (0-3'), and MW-135 (0- 3') due to outliers in the inductively coupled plasma (TCP) serial dilution analysis. • Chromium was estimated in sample MW-13 (2-3.5') due to an outlier in the ICP serial dilution analysis. • Selenium was estimated in sample MW-13 (2-3.5') due to graphite furnace atomic absorption analytical spike recovery. As stated above, with the exceptions noted, the data was found to be acceptable and usable and meet the data quality objectives for the Phase n Remedial Investigation. The qualifications given to the results discussed above are based on the USEPA data validation guidelines and, given the relatively small number of samples qualified, especially for the compounds discussed, are well within the normal range for a validated data set of this size.

TUT CO5 12O1 GERAGHTY & MILLER. INC. APPENDIX L DATA VALIDATION SUMMARY OF THE PHASE D REMEDIAL INVESTIGATION WATER RESULTS TUTU WELLS SITE ST. THOMAS, U.S. VIRGIN ISLANDS OVERVIEW As part of the Phase H Remedial Investigation at the Tutu Wells Site, located in St. Thomas, U.S. Virgin Islands, Geraghty & Miller, Inc. collected water samples from May through July 1994. A majority of the May through June 1994 data were validated; the validation results are discussed in this Appendix. Several of the water-supply well samples collected in May and June 1994 and all of the samples collected in July 1994 did not have to be validated. SAMPLING Groundwater wells and water-supply wells were sampled from May through July, 1994. The samples were delivered to the laboratory using chain-of-custody (COC) procedures, and the laboratory provided the analytical data results in 28 sample delivery groups (SDGs). Each SDG was assigned a unique laboratory project number. An SDG and sample identification (ID) summary is provided in Table L-l. Sixty-seven water samples, four field replicates, four field blanks, and 28 trip blank samples were collected during the sampling period. Samples Four Winds I, CHT-6D, MW-7, MW-3, and SW-7 were also analyzed as matrix spike/matrix spike duplicate (MS/MSD) samples. Several of the water-supply well samples collected in May and June 1994 and of all the samples collected in July 1994 did not have to be validated and are not discussed in this report. The data from water-supply wells Gassett, Steele, Eglin I, Eglin TO., La Place, WTS-2 (Port 3), and Mathias, which were sampled in May and June 1994, were not validated. TUT COS 1.202 GERAGHTY & MILLER. INC. L-2 ANALYSIS The samples were sent to Enseco-East in Somerset, New Jersey for analysis of the target compound list (TCL) volatile organic compounds (VOCs), TCL semivolatile organic compounds (SVOCs), target analyte list (TAL) dissolved metals, TAL total metals, cyanide, and three site- specific VOCs. The site-specific VOCs included the following compounds: methyl tertiary-butyl ether (MTBE); 1,2-dibromoethane (EDB); and n-propylbenzene. In addition, a majority of the samples collected were analyzed for total dissolved solids, total suspended solids, alkalinity, hardness, ferrous iron, chloride, nitrite, nitrate, phosphorous, sulfate, sulfide, chemical oxygen demand, and organic lead. Two samples collected on June 29, 1994, DS-1 and DS-2, were only analyzed for the Toxicity Characteristic Leaching Procedure (TCLP) parameters, ignitability, corrosivity, and reactivity. Samples collected from the Gassett, Harthman Race Track, Delegarde, VIHA I, WTS-1 (Port 3), and WTS-2 (Port 3) supply wells were analyzed for TCL VOCs according to U.S. Environmental Protection Agency (USEPA) Method 524.2 Revision 3.0 (USEPA 1989) with USEPA Region II modifications. Geraghty & Miller requested that these supply well samples be analyzed for the three site-specific VOCs. However, none of the samples analyzed according to Method 524.2 was analyzed for these additional compounds. AH the other VOC samples and all the SVOC samples were analyzed in accordance with USEPA Contract Laboratory Program (CLP) methodologies contained in the March 1990 Statement of Work (SOW) for Organics Analysis (USEPA 1990a). The metals and cyanide were analyzed in accordance with the USEPA CLP methodologies contained in the March 1990 SOW for Inorganics Analysis (USEPA 1990b). Analyses for the other parameters were conducted in accordance with the methods and requirements of the quality assurance project plan (QAPP) prepared for the remedial investigation at the Tutu Wells Site (Geraghty & Miller, Inc. 1992). TUT OO!=i GERAGHTY & MILLER, INC. L-3 VALIDATION All VOCs, SVOCs, metals, and cyanide were validated in accordance with the USEPA Region n data validation guidelines for organic and inorganic analyses performed in accordance with CLP methods for routine analytical services. The guidelines for validating organic and inorganic data are provided in the USEPA Region TJ Standard Operating Procedures (SOPs) numbered HW-6, Revision 8 and HW-2, Revision 11, respectively (USEPA 1992a; 1992b). MTBE, EDB, n-propylbenzene, and Method 524.2 results were reviewed and validated using the USEPA Region H guidelines for TCL VOCs (USEPA 1992a). Individual organic and inorganic data review checklists and data assessment narratives were completed for each SDG. This information and any required tables pertaining to the data assessments may be found under their SDG number in Attachments L-l through L-47. The information about the data review of MTBE, EDB, n-propylbenzene, and Method 524.2 VOCs is located in the organic data assessment narratives for each SDG. OVERALL ASSESSMENT Overall, the majority of the data submitted by Enseco-East for analysis are of good quality and demonstrate acceptable precision, accuracy, and completeness. Some of the reasons for data qualification are discussed below. Detailed discussions regarding the validation of the data and the qualifiers added to the results are found in Attachments L-l through L-47. When analyzing VOC samples following Method 524.2, the laboratory failed to calibrate the instruments for MTBE, EDB, or n-propylbenzene. However, if these compounds were present in the samples, they would have been detected as tentatively identified compounds (TICs). When analyzing VOC samples following the CLP method, the laboratory failed to perform five-point initial calibrations for MTBE, EDB, or n-propylbenzene. Only single-point calibrations were routinely performed for these site-specific compounds. Therefore, all the MTBE, EDB, and n- GERAGHTY & MILLER, INC. TUT oos 1204 L-4 propylbenzene sample results were estimated because of calibration deficiencies. Some data generated for the TCL VOC and TCL SVOC analyses were rejected because of low response factors reported in the calibration analyses. Several coolers containing samples being shipped from the site to the laboratory were delayed in customs. As a result, cooler temperatures were above 7 degrees Celsius when the coolers were received at the laboratory. Therefore, the VOC and SVOC results for the samples contained in these coolers were estimated. For several trip blanks and one field blank, the volatile organic analysis (VGA) vials containing these blanks contained air bubbles. The non-detect results for these blanks were rejected, and the positive results were estimated. Several aluminum sample results were rejected because of high MS recoveries. A few thallium sample results were rejected because of a low MS recoveries. Several metal results for sample CHT-3 were rejected because the concentrations of the dissolved metals exceeded the concentrations of the total metals by more than 50%. As stated above, with the exceptions noted in the attachments, the data were found to be acceptable and usable, and the data meet the data quality objectives for the Phase II Remedial Investigation. The qualifications of the results discussed in this Appendix are based on the USEPA data validation guidelines and, given the relatively small number of samples qualified (especially for the parameters discussed), are well within the normal range for a validated data set of this size.
