Virgin Islands. The objectives of this investigation were to: • Better define the extent and magnitude of petroleum hydrocarbon contamina- tion that resulted from past gasoline product releases at or near the site. • Obtain data to determine if site activities contributed to the observed halogenated volatile organic compound (HVOO plume in the Turpentine Run area. • Collect the necessary soil and groundwa- ter chemical data in order to design a remedial measure to remove petroleum hydrocarbon contaminants from the subsurface. The investigation of the unsaturated zone at the site consisted of visual inspection of all waste management units, including service bay sumps, oil/water separator, infiltration gallery, septic tank and waste oil drum storage area, and laboratory analysis of soils collected from borings adjacent to or under these units. The groundwater investigation consisted of drilling four on-site and one off-site shallow monitor wells and two on-site deep monitor wells. Soil samples were collected from each monitor well boring for laboratory analysis, and groundwa- ter analytical samples were collected from the monitor wells, including three pre-existing on- site wells, after the new wells were fully developed. The off-site monitor well (TT-6) was drilled approximately 400 feet downgradient of the site to determine the limits of the groundwater petroleum-related plume emanating from the area of the Texaco release point. All soil and water samples were analyzed for volatile organic compounds (VOCs), including benzene, toluene, ethylbenzene, and xylenes (BTEX) and tert- butyl methyl ether (MTBE). Split samples were obtained by A.D. Little from the infiltration gallery, waste oil drums, and one monitor well located within the site boundary. Split samples were also obtained by Blasland and Bouck personnel from soil borings and monitor wells located within the site boundary. The results of GCL's field investigation show mat BTEX compounds are the only contaminants detected in soil samples at the site. These contaminants are related to residual contamination from the old underground storage tank (UST) pit and minor releases of waste oil from one service bay sump and the oil/water separator. Other than small concen- trations of ambient or laboratory contaminants, HVOCs were not detected in any soil samples or in the five samples taken from the bottom of the infiltration gallery. HVOCs were detected in one waste oil drum sampled by Arthur D. Little and Associates (and split by GCL) during the field investigation. Although HVOCs were likely purchased in small quantities and used in service operations at the site, they were not detected in soil samples from the service bays or oil/water separator and infiltration gallery, which received the effluent from the service bays. The groundwater investigation has shown that the center of mass of the dissolved BTEX plume related to gasoline releases in the area of the Texaco Tutu service station is under the south end of the Texaco site, and norm of the Tillett supply well. Natural processes of volatilization and biodegradation, aided by turbulence along fractures induced by past pumping of the Tillett well, effectively attenu- ated BTEX after less than 400 feet of downgradient transport. Higher concentra- tions of HVOCs in the deeper aquifer versus the shallow aquifer under the Texaco site 1 Environmental Science and Engineering A BDU ntmtHonu Comfw TUT GO 5 .1365 Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands suggest that HVOCs originated from a source or sources other than of the Texaco site. The absence of HVOCs in soil samples, the oil/ water separator, and the infiltration gallery at the Texaco site is further evidence that these compounds did not originate from the site. Based upon the findings of the field investigation and nature of the site geology, GCL recommends a remedial strategy aimed at removing residual petroleum hydrocarbons from soils in and adjacent to the old UST pit area. GCL believes a strategy of vapor extrac- tion from soils will prevent further migration of hydrocarbons into ground water underlying the site. Environment*!

Virgin Islands (Figure 1). It is located at the intersection of Highways 38 and 384, south- west of the former LAGA Building, northeast of the Four Winds Shopping Center, and north of the Tillett Gardens Shopping Center (Figure 2). The site has been part of a larger scale investigation of ground water contamination originating at a number of facilities in the upper Turpentine Run area. Since it was built in 1964, the Texaco Tutu service station has been in continuous opera- tion. It is a retail outlet for gasoline and diesel fuel, and until recently, also provided minor automotive mechanical servicing, such as oil changes, brake repair, and lubrication. Fuel has been stored at the site in USTs. The origi- nal USTs and associated piping were removed in 1988 and replaced with new facilities at a different location at the site. 2.2 SITE HISTORY In Jury 1987, water from a supply well in the Tillett Gardens Shopping Center was reported to have an unusual taste and odor. Ground water from that and other supply wells in the area were analyzed and found to contain gasoline constituents and solvents, such as HVOCs. As a result of the presence of these constituents, the U.S Virgin Islands Depart- ment of Planning and Natural Resources (DPNR) ordered the shutdown of 18 wells in the area by September 1987. Several wells in the area have continued to supply water for non-potable use. 22.1 PETROLEUM PRODUCT RELEASES From 1976 to early 1987, several possible releases of petroleum products into soils from the USTs at the site were reported. In Septem- ber 1987, GCL conducted a soil-gas survey at the Texaco Tuto service station. The survey revealed the possible presence of petroleum constituents on and around the service station, which were assumed to have been the result of gasoline releases from the USTs (GCL, 1988). In September 1988, Lebron Associates was contracted to remove the three original steel USTs and replace them with double- walled steel tanks at a different location on site. Soils removed from the tank excavation were placed along the north and east walls of the site and allowed to vent through a series of perforated PVC pipes placed within the soil stockpiles. Strong hydrocarbon odors contin- ued to be monitored in the excavation pit after removal of the old USTs, and the pit was backfilled with dean, gravelley day soils (Lebron and Associates, 1990). The stockpiled soils were eventually removed from the site and landfllled (Vemon Morgan, Texaco Tutu service station operator, personal communica- tion). 222 ALLEGED RELEASES OF HALOGENATED VOLATILE ORGANIC COMPOUNDS Minor automotive servicing and repair has historically been conducted at the site at three service bays next to the office building (Figure 3). Services included oil changes, rune- ups, brake jobs, and minor engine adjustments. Small quantities of auto decreasing agents may have been purchased from off-site retail stores and used at the site. Environment*!

NO.: FILE: SITEPL2.CWG TUT 005 137O Phase I Remedial Investigation Report St Thomas, U.S. Virgin Islands From 1972 until the mid-1980s, waste and wash-down water was cycled from sub-grade sumps under each service bay to an API oil/ water separator via 4-inch steel pipes. From the mid-1980s to the time the service bays were shut down in 1992, waste oil was captured and stored on site in 55-gallon drums. A 10-foot deep infiltration tank con- structed of rockwall and cinder block is present at the site, and was used to process wastewater from the oil/water separator and the station's septic tank. The infiltration gallery was taken out of service in February 1992, when the station's septic system was hooked up to the municipal sanitary sewer system. The oil/water separator and infiltration tank have been evaluated as possible pathways for HVOCs to pass into the ground water at the site. However, analyses of wastewater from the oil/water separator did not detect chlori- nated solvents in 1988 and 1989 (COM FPC, 1990a and COM FPC 1990b), and analysis of wastewater samples from the infiltration tank did not detect any tetrachloroethene (PCE) or its decay products in 1991 (Hydrologic Associ- ates, USA., 1993). Furthermore, analyses of samples of waste oil from the 55-gallon drums did not detect PCE or trichloroethene (TCE) in 1989, although methylene chloride and trichloroethane (TCA) were detected as "J" values in two drums (COM FPC, 1990a and 1990b). 2.3 GOALS AND OBJECTIVES The primary objectives of the Texaco Tutu site investigation were to: • Better define the extent and magnitude of petroleum hydrocarbon contamina- tion emanating from USTs as a result of the product releases at the Texaco Tutu site. • Obtain data to determine if site activities contributed to the observed HVOC groundwater plume in the Turpentine Run area. • Collect the necessary soil and groundwa- ter chemical data to design a remedial measure to remove petroleum hydrocar- bons from the subsurface. • Understand how contaminants migrate from the Texaco Tutu site under past and present conditions is an important element in the design of an integrated remedial strategy for the Turpentine Run area. Environmental Science *nd Engineering TUT 005 137.1. Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands 3.0 METHODS Held investigation methods followed a scope of work outlined in GCL's Site Assess- ment and Interim Remedial Measures Workplan (1993b). Modifications to the workplan, such as changes in sampling depth and addition of soil boring sites and one monitor well, were dictated by field conditions. The field investigation was carried out by Louis J. Mazzullo, project hydrogeolbgist, and Patrick Montano, master technician. Mr. Mazzullo and Mr. Montano conducted simulta- neous soil boring surveys and monitor well installations. Ranee Hall, associate engineer, collected water level data and supervised the deanout and inspection of the oil/ water separator. Mr. Clifford Crook and Mr. Adrian Schottroff, environmental specialists for the US. Virgin Islands Department of Planning and Natural Resources, visited the site and provided oversight during the course of the investigation. Held investigators documented site activities with 35 mm photographs. Representative photographs are included in Appendix A. The site investigation was conducted using the Health and Safety Plan developed by Geraghty and Miller (1991). Activities were primarily conducted with Level D personal protection equipment (PPE), which included hard hats, safety shoes, safety glasses, ear protection, and gloves. Level C PPE, which included full-face respirators and Tyvek suits, were used when cleaning out the service bay sumps. A photo-ionization detector (PID) and combustible gas indicator (CGI) were used to continuously monitor conditions around the rig during the drilling and development of monitor wells and soil borings. The PID and CGI were calibrated at the start of each work day prior to entering the work site. All equipment was thoroughly decon- taminated prior to commencing field work. All drilling equipment, including drill pipe, bits. hand tools, and well casing, was steam-cleaned with pressurized water heated to a tempera- ture of not less than 160 degrees Fahrenheit prior to down-hole use at each soil boring and monitor well site. Sampling tools were decon- taminated with an Alconox detergent, deion- ized water, and methanol wash prior to use and between sample runs. The submersible pump used for well development was decon- taminated between each well using an Alconox wash followed by a freshwater rinse. 3.1 UNSATURATED ZONE INVESTIGATION The investigation of contaminant contri- butions from the unsaturated (soil) zone at the site involved: • Drilling soil borings adjacent to the waste management units (service bay sumps, septic tank, infiltration gallery, and oil/water separator). • Submitting selected soil samples for laboratory analysis. • Evacuating the oil/water separator and septic tank. • Visually inspecting all waste units for structural integrity. Most of the soil borings were advanced with a hand auger, but site conditions necessi- tated the use of the drilling rig to advance three of these borings. In addition, soil samples were collected during the drilling of the monitor wells at the site. These samples were collected by running the hand auger through the drill table. Soil samples were collected and submit- ted for analysis according to procedures outlined in GCL's workplan (1993b). Investiga- 8 Environmental Science and engineering A SOU/nwnaaon* Compmy TUT 1372 Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands tive and quality assurance/quality control (QA/QC) samples collected during the investi- gation were analyzed for VOCs (Environmen- tal Protection Agency Method 8240 + xylenes andMTBE). 3.1.1 SERVICE BAY SUMPS The sumps in the three service bays were checked for structural integrity after each one was cleaned out by removing wastewater and sediment to 55-gallon drums. The first soil borings were placed alongside the three service bay sumps (Figure 3). GCL personnel collected two soil samples from each of soil borings SB-1, SB-2, and SB-3. Sampling depths in these borings were from 3 and 5 feet below the surface instead of from 25 and 5 feet, as called for in the workplan. Soil samples were taken at 3 feet at Texaco's request because this depth corresponded to the depth of the bottom of the service bay sumps adjacent to which the borings were placed. 3.2.2 DRUM STORAGE AREA Borings SB-4 and SB-5 were placed in the former drum storage areas (Figure 3). Sample depths in these borings were restricted by shallow depth to weathered bedrock, where auger refusal was experienced. Two soil samples were obtained from SB-4 (25 and 3.8 feet) and one sample was collected from SB-5. After discovery of stained soils along the north fence, SB-6, which was not called for in the workplan, was placed on the north side of the site with Texaco's concurrence. Samples were collected for analysis from 2.4 and 3.8 feet in this boring, the latter depth corresponding to the top of weathered bedrock where auger refusal was experienced. 3.13 OH/WATER SEPARATOR, INFILTRATION GALLERY, AND SEPTIC TANK Soils adjacent to these waste management units were sampled and structures visually checked for structural integrity. The oil/water separator and septic tank contained wastewa- ter, and had to be pumped out prior to inspec- tion. A water sample from the oil/water separator was first analyzed and shown to be free of contaminants before pumping. To ensure that maximum soil penetration was achieved alongside each of these units, the drill rig was used to advance the soil borings, and samples were collected through the drill table with a hand auger. Boring OW/SB-1 was drilled next to the oil/water separator, and a soil sample was collected from 95 feet below the surface, which corresponds to the base of the unit Boring IG/ SB-1, adjacent to the infiltration gallery, was sampled at 5 feet below the surface although the base of the gallery is at 10 feet The sam- pling depth corresponded to the base of the soil zone at which weathered bedrock was encountered and auger refusal was experi- enced. In addition, a sample of the base course sand from the bottom of the infiltration gallery (IG/SB-2), at 10 feet below ground level, was collected by lowering the hand auger through an opening jackhammered into the concrete cover of this unit. Boring ST/SB-1, adjacent to the septic tank, was sampled from 5 to 55 feet below ground level, where auger refusal was experienced. The base of the septic tank was measured at 9 feet below the surface 3.1.4 MONITOR WELL BORINGS Samples were collected from the unsatur- ated soils encountered during drilling of the monitor wells installed on site. Soil samples GCL Environmental Science and Engineering A BOU HHinioon* Conpgiy TUT O05 1373 Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands were collected every 25 feet using a hand auger from 25 feet below ground surface to 4 feet below the water table, or when sampler refusal was encountered. Some modifications to the workplan were necessitated by site conditions, such as shallow depth to bedrock and the presence of rocky soil that prevented sample recovery at the precise sampling depths. Soils were immediately placed in sealed plastic bags for field head-space analysis with a FID. A second bag was filled for potential laboratory analyses and stored on ice. Samples submitted for laboratory analy- sis included soil from the interval directly above the saturated zone and the interval exhibiting the highest FID head-space reading. Two soil samples were collected from each of the following monitor well borings: TT- 1, TT-ld, TT-2, TT-4, and TT-5. Because of the shallow depth to bedrock (less than 25 feet), soil samples could not be obtained for labora- tory analysis from TT-3d and TT-6. Monitor well TT-4 was installed in the middle of the old UST basin (Figure 3). Field head-space and laboratory analysis of soil samples from boring TT-4 provide information on past releases from the original UST basin and the extent of hydrocarbon<ontaminated soil at this location. 3.2 SATURATED ZONE INVESTIGATION GCL installed five shallow and two deep ground water monitor wells during this field investigation. These wells were intended to: • Assess the on-site contribution of con- taminants to the existing contaminant plume beneath the Tutu Turpentine Valley. • Delineate the horizontal extent and concentration of contaminants in groundwater beneath the site, and determine if contaminants were derived from upgradient sources. • Provide basic data needed to design the remedial system. Well TT-6, which was not specified in the workplan, was drilled southwest of the site in the Four Winds Shopping Center parking lot. This well was drilled with the concurrence of Texaco and the Four Winds Shopping Center, and was permitted by the DPNR (Appendix 8). 3.2.1 DRILLING METHODS Monitor wells were drilled with an air rotary rig with air hammer capabilities. To facilitate sampling and reduce rig standby time, soil samples were collected, as described in Section 3.1.4, with a hand auger, rather than with a split-spoon sampler tool as originally proposed in the workplan. Mr. Mazzullo provided lithologic descriptions and field head-space measurements on standard litho- logic description forms (Appendix Q. Appen- dix D includes completion diagrams of all monitor wells installed during this investiga- tive phase. The soil zone in each monitor well boring was air-drilled with a 10-inch tri-cone bit until the base of contamination was reached, or to just above the soil/saprolith contact Tomini- 10 A eon tmmuoral Ccmpinr TUT 005 1.374 Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands mize cross-contamination from the shallow soil zone to deeper saprolith and bedrock zones, a temporary conductor pipe was set in each monitor well boring (Photo 8) in the 10-inch hole. Prior to running back into the hole with the hammer bit, a circulation ("blooey") line was attached to the conductor pipe so drilling fluids, cuttings, and formation water could be directed to a temporary lined pit Hammer drilling was accomplished with freshwater or water mixed with a small volume of methanol- based foam, which was approved by the DPNR. Solids and fluids produced from the wells were then transferred to drums or directly to wastewater tanks on site. 3.2.2 WELL CONSTRUCTION The deep monitor wells (TT-ld and TT- 3d) were drilled to provide information on vertical contaminant plume configurations on the downgradient and upgradient sides of the site. The wells were constructed with 2-inch PVC casing and 0.020-slot PVC screen. The workplan called for a 10-foot screen at the bottom of each well to a total depth of approxi- mately 55 feet A 10-foot screen was set from 53 to 43 feet in TT-3d. Adverse hole conditions (caving) in this well prevented the bentonite seal from being placed below 30 feet. Due to high water production and adverse hole conditions in TT-ld, it was elected to set a 5- foot screen from 503 to 453 feet in this well. Both wells, however, are screened below the screened intervals in adjacent shallow monitor wells (MW-3 and TT-1, respectively). Con- struction details for these wells are presented in Appendix D and summarized in Table 1. The proposed on-site remedial measure wells OT-1, TT-2, TT-4, and TT-5) were all drilled to an approximate depth of 35 feet below grade. These 4-inch PVC wells were completed with a 20-foot, 0.020- or 0.010-slot PVC screen placed across the water table interface. Monitor well TT-6 in the Four Winds Shopping Center parking lot was completed with a 10-foot screen because severe hole caving from the saprolith zone prevented placement of a longer screen. 3.2J WELL DEVELOPMENT All monitor wells were developed after the grout seal was fully cured. A 3.5-inch O.D. submersible pump was used to develop the 4- inch shallow monitor wells, and 13-inch O.D. teflon bailers were used for the 2-inch deep wells. Development included purging at least three casing volumes per well, until field parameters (pH, specific conductivity, and temperature) stabilized for at least three successive readings. Well development field data, including water levels, field parameters, physical characteristics of the water, and volume developed, were recorded on GCL's standard well development form (Appendix E). 3.2.4 WELL SAMPUNC After development of each monitor well, groundwater investigative and QA/QC samples were collected in accordance with the GCL workplan (1993b). These samples were submitted for analysis of VOCs (Environmen- tal Protection Agency Method 8240 + xylenes). Pre-existing monitor wells MW-3, MW-4, and MW-4d located on the Texaco site were also sampled after being purged of at least three casing volumes using the submersible pump. 3.2.5 SURVEYING In March 1994, personnel from Geraghty and Miller supervised well surveys of the monitor wells installed by GCL at the Texaco site and well TT-6 in the Four Winds Stopping Center. Ground level and top of casing elevations of all the monitor wefls are presented in Table 1. 11 Environmental Seance and Engineering A BAAJ IMWMMMV1*/ rui 1375 H £ Table 1 Monitor Well Specifications, December 1993 Well No. TT-1 TT-1d TT-2 TT-3d TT-4 TT-5 TT-6 Total Depth Ft.

Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands 4.0 GEOLOGY AND HYDROGEOLOGY 4.1 GENERAL HYDROGEOLOGY OF THE TURPENTINE Rim AREA Details of area-wide geology and hydrogeology of the Turpentine Run area are provided by Geraghty and Miller (1993a). The Texaco Tutu service station is located in the upper Turpentine Run of east-central St. Thomas. The bedrock in this area consists of two Cretaceous volcanic units referred to as the Water Island Formation and the younger Louisenhoj Formation. The Water Island Formation is composed primarily of extrusive basalt and basalt breccia, which is unconfonnably overlain by dark greenish-gray augite-andesite breccia and ruff. The base of the Louisenhoj Formation contains the Cabes Point Conglomerate, which was derived by erosion of the underlying Water Island rocks (Donnelly, 1966). The Water Island and Louisenhoj Forma- tions are both present in the upper Turpentine Run (Donnelly, 1966). They are offset by a number of strike-slip and normal faults. The bedrock is highly jointed and locally more intensely fractured. Major fault/fracture zones appear to be present along the north-south axis of Route 38, where it runs southward from the Texaco site (along the axis of Turpentine Run), and east to west along Route 38, where it runs eastward from the Texaco station. These tectonic features are identifiable on aerial photographic steropairs. Many joints and fractures are filled with secondary calcite (Appendix A, Photo 21). The bedrock is locally overlain by a weathered (saprolith) horizon of variable thickness characterized by clay-supported cobbles and boulders of the volcanic rock (Photo 22). The interstitial day appears to be composed of monrrnorillonitic arid possibly kaolinitic alteration products of the original bedrock. The saprolith zone is overlain in places by a thin-to-moderately bedded mantle of clay-rich soil or, along the valley floors, Quaternary alluvial deposits. The primary aquifer in the area is the fractured volcanic bedrock (Jordan and Cosner, 1973; Geraghty & Miller, 1993a). The fractures are the main conduits for groundwater flow under the area because the rocks exhibit very little primary porosity. Consequently, ground- water yield from wells drilled into the bedrock is dependent upon the intensity and intercon- nection of fractures intersected by the wellbore. The secondary aquifer in the area consists of the alluvial deposits in the lower Turpentine Run basin. The alluvial deposits in the upper basin, where the Texaco Tutu service station is located, are not capable of supplying usable amounts of water because of their limited thickness and lateral extent, and because they are commonly unsaturated. The alluvial deposits have been considered to be hydrauli- cally connected to the fractured bedrock, and groundwater in the area is thought to exist under water table conditions, with localized low-permeability layers in the alluvium resulting in localized confined conditions (Geraghty and Miller, 1993a). Groundwater flow in the shallow and deep aquifers has generally been to the south, and is controlled by the major fracture systems and pumpage from area water production wells. 4.2 SITE HYDROGEOLOGY 42.1 GENERAL SITE GEOLOGY The Texaco Tutu service station is located at the intersection of a north-trending "gut" of Turpentine Run and another major east-to-west fracture zone sub-parallel to Route 38. The 13 Environmental Science and Engineering TUT COS 1377 Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands geology of the site is defined by lithologic data obtained from nine new soil borings and six new monitor well borings drilled during this investigation, ranging in depth from 2J> to 55 feet below ground level, and pre-existing monitor wells MW-3, MW-4, and MW-4d. Table 2 summarizes hydrogeologic data obtained from the new borings. The site is underlain by a variable thick- ness of saprolith and surficial clayey soils that overlay fractured, augite-andesite breccia of the Louisenhoj Formation. The Cabes Point Conglomerate and underlying Water Island units were not intersected in any of the borings drilled at the site or in the Four Winds Shop- ping Center parking lot. Monitor well TT-6 was drilled 400 feet southwest of the Texaco Tutu service station in the Four Winds Shopping Center parking lot. It is situated in the axis of the Tutu Gut" fracture zone. Figure 4 is a lithologic cross- section from the Texaco site to that well. The cross-section shows that the south end of the Texaco site (i.e., across the street at the north side of Tillett Gardens) is bounded by an up-to- south fault that brings saprolith to the surface (with a corresponding topographic rise in that direction-Photo 23). The existence of mis fault is indicated from the surface outcrop of saprolith in the Tillett parking lot and from identification of lineaments on aerial photo- graphs. The weathered zone thickens substan- tially toward the Four Winds Shopping Center parking lot. This thickening may be supple- mented by the admixture of alluvium with the weathered bedrock. 4.Z2 BEDROCK HYDROGBOUOGY Figure 5 shows that the depth to the fresh andesite breccia bedrock ranges from 11 to 275 feet below the surface in borings placed on the Texaco Tutu service station site. This map also represents the composite thickness of the overlying saprolith and soil zones. A bedrock "high" or ridge extends diagonally under the site and plunges to the southwest. The flanks of this high dip steeply to the southeast and moderately to the northwest. Most of the sofl boring locations associated with the waste management units are on the crest or north- west flank of this bedrock high, whereas the old UST pit is located on the southeast flank. The fresh bedrock under the site appears to yield most, if not all, of the water produced in the monitor wells. Field investigators noted that water was not produced during drilling until the bedrock was encountered, and prolific water production did not occur until larger open fractures were encountered (usually between 27 and 35 feet below the surface). Groundwater elevations in the on-site shallow monitor wells, including existing monitor wells MW-3 and MW-4 (Table 2), indicate a generally southerly flow direction (Figure 5) with a gradient of 0.018 ft/ft. Groundwater enters the site from the north- west and northeast, which corresponds to the primary fracture directions observed in nearby bedrock outcrops (Photo 21). The deep groundwater flow direction, defined by on-site monitor wells TT-ld, TT-3d, and MW-4d, is essentially due south with a gradient of 0.017 ft/ft. 423 Son. AND WEATHERED BEDROCK Figures 6 and 7 show the thickness of the clay-rich soil above the saprolith under the site. Undisturbed soil is composed of red-brown to green-gray and green-brown, slightly moist clay and sandy days, except in the area of the old UST pit. This area was filled with gravelly clay that was imported from an unknown source on the island. The soil is stained to a dark gray color where it has been impacted by 14 and Engineering TUT 005 1378 Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands Table 2 Hydrogeologic Data from Monitor Wells and Soil Borings Boring No. B/Soil FtBGL B/Saprolith FtBGL Saprolith Thickness, Ft Initial H2O Level, Ft Below Top of Casing H2O Elev.

These samples were submitted for laboratory analysis for VOCs using Environmental Protection Agency Method 8240. Figure 10 presents summaries of all soil analyses from this investigation, which are also summarized on Table 3 and detailed in Appendix F. The only constituents detected in the soil samples analyzed from the Texaco site were petroleum hydrocarbon constituents (BTEX and MTBE) associated with gasoline leakage from the old UST tank site, and petroleum hydrocarbon constituents (ethylbenzene) associated with waste oik that stain shallow soils near the oil/water separator, SB-1 (west service bay), and SB-6 (former UST pit soil stockpile area). Other constituents detected included carbon disulfide, acetone, and 2- butanone. HVOCs were not detected in any of the soil samples on site submitted for labora- tory analysis. It was not possible to sample soils in the TT-6 well boring in the Four Winds Shopping Center parking lot because the soil horizon was only 15 feet thick. 5.1.1 OLD UNDERGROUND STORAGE TANK PIT Gasoline-related constituents are confined to the south half of the Texaco site, and ema- nate from the original UST leakage point at the location of TT-4. Imported soils used to fill the old UST pit have been impacted by low levels of residual BTEX constituents (36 to 62 parts per billion, or ppb) from the pit area, as are shallow soils (above 10 feet) in the vicinity of the TT-1 well cluster (31 to 186 ppb). There were no measurable readings of VOCs with the FID during drilling of the saprolith under the soils impacted by the gasoline. 5.1.2 SERVICE BAY SUMPS The service bay sumps measured ap- proximately 2 feet by 2 feet wide and 3 feet deep and are constructed of concrete Soil borings were placed approximately 2 feet from the southwest corner of each sump (Figure 3). The sump adjacent to SB-3 (east service bay) had a slight gap between the concrete wall and base, but analysis of soils in SB-3 showed no detectable VOCs. The sump adjacent to SB-2 (middle service bay) appeared to be fully intact, and soil samples were also free of VOCs. GCL discovered a freshwater teak from the service station's water line that entered the west service bay sump through a small crack around the discharge outlet port. Soil at the base of SB-1 adjacent to this sump showed a T value for ethylbenzene at 13 ppb. This impact was limited to a few inches at the bottom of the borehole near the contact with the underlying saprolith zone (Figure 8). 5.13 DRUM STORAGE AREA Two soil borings (SB-4 and SB-5) were advanced in the former waste oil drum areas along the north and east sides of the site (Figure 3). These borings are located in areas paved with concrete. In addition, boring SB-6 was drilled in the unpaved area along the north fence where soils from the excavated UST pit were stockpiled and vented. Boring SB-4 encountered weathered bedrock at 38 feet below the surface. VOCs were not detected in soil samples analyzed from 23 and 3.8 feet in this boring. Boring SB-5 encountered saprolith at 25 feet. A soil sample from above the soil- saprolith contact also did not show any VOCs on analysis. Boring SB-6 intersected the saprolith at 3.8 feet. Soils in the basal few inches of this boring were stained with heavy waste oil, and analyses showed low levels of ethylbenzene (41 ppb), acetone (180 ppb), and 2-butanone (34 ppb). 23 Environment!

The con- crete base of the unit could not be inspected because of the presence of a thin layer of sludge after pumpout A sample of the water that filled the unit was submitted for analysis prior to cleanouL That sample showed no detectable VOCs (Table 4). Soil staining was found in adjacent boring OW/SB-1 at depths of 6 to 10 feet below the surface, above the contact with the saprolith (Figure 9). A soil sample submitted for analysis from 95 feet showed 67 ppb ethylbenzene. No other VOCs were detected other than 40 ppb acetone, which was also detected in the method blank. The interior of the infiltration gallery was visually inspected through an opening jackhammered through the concrete cover of the unit The unit was found to be free of any fluids, although the base course sand was very moist. Samples of this sand that were analyzed by GCL and split samples analyzed in conjunc- tion with A. D. Little and Associates, showed no detectable VOCs (Table 5). The soil sample from adjacent boring IG/SB-1 showed no detectable VOCs (Figure 9). That sample was obtained from the interface between the clayey soils and saprolith at 5 feet below the surface. The base of the infiltration gallery was mea- sured at 10 feet below die surface. The septic tank was pumped out and visually inspected. It was found to be con- structed of concrete and appeared to be fully intact. The water pumped from the unit did not have any discernible odor or sheen. The base of this unit was measured at 9 feet below the surface. A soil sample from 5 feet in adjacent boring ST/SB-1 was analyzed and did not contain any detectable VOCs. 5.1 J WASH On. DRUMS Arthur D. Little and Associates con- ducted additional activities at the site during GCL's field investigation. Activities included selected sampling of existing waste drums, not including cuttings and fluids recovered from the current soil borings and monitor well. GCL provided field oversight of these activities and obtained splits of all samples collected by Arthur D. Little and Associates. Most of the 46 waste drums on site were field-screened for VOCs by Arthur D. Little using a Dexsil-Clor-D-Tect Q4000 Quantitative test kit with a specified range of 200 to 4,000 parts per million (ppm). Results of this field screening are summarized in Table 5. Arthur D. Little selected several drums for individual and composite sampling for analysis by Environmental Protection Agency Method 8240 (including xylenes). Results of those analyses are summarized in Table 6 and detailed in Appendix G. BTEX compounds, primarily the toluene, ethylbenzene, and xylene constituents, were found in two individual drums and the three-drum composite sample.

Figures 12a and 12b show the shallow and deep zone dissolved BTEX plumes, respec- tively, under and south of the Texaco site. 5.2 J PETROLEUM-RELATED CCWEUONANTS Petroleum-related constituents were detected in shallow monitor wells at and south of the site. No free-phase hydrocarbons were measured in any of the wells. The highest dissolved BTEX concentrations were found in shallow monitor well TT-4 (68,000 ppb), which was drilled in the middle of the old UST pit where petroleum discharge occurred. BTEX concentrations in the shallow zone are as high as (48,000 ppb) in TT-1, but diminish abruptly toward TT-5 (55 ppb) to the east, MW-4 to the west (22 ppb), and TT-2 (5 ppb) and MW-3 (12 ppb) to the north (Figure 12a). Benzene concentrations in the shallow zone range from 1 ppb (a T value in TT-2) to 23,000 ppb in TT- 4. TT-6, a shallow zone well in the Four Winds Shopping Center parking lot, showed a total BTEX concentration of 2.1 ppb, which was entirely a benzene'T value. BTEX was not detected in MW-6 or MW-7 during the most recent sampling of those wells. MW-6 provides closure of the BTEX plume to the west, and MW-7 provides dosure to the southeast. The center of mass of the shallow aquifer BTEX plume in the area of the Tutu station appears to be directly under the south end of the Texaco site (Figure 12a). BTEX concentrations in deep monitor wells on site range from non-detects to 2,545 ppb (in TT-ld). The most recent analysis from the Tillett supply well showed a total BTEX concentration of 7 ppb, whereas the most recent sample from MW-6d was non-detect for BTEX. BTEX contamination in the deeper aquifer likewise appears to be centered dose to the Texaco site (Figure 12b). MTBE concentrations in the shallow zone range from 0 ppb (MW-3) to 52,000 ppb (TT-4) under the site, and 150 ppb in TT-6 (table 4). The only deep well in which MTBE exceeded T values was TT-ld (1,500 ppb), under the Texaco site. MTBE is a gasoline additive that is commonly associated with BTEX constituents in product releases. There are currently no Federal or territorial standards for MTBE in ground water. 5.2.2 HALOCENATED VOLATILE ORGANIC COMPOUNDS HVOCs were detected in deep and shallow groundwater under the site and in shallow groundwater in TT-6. The primary compounds detected were 1,2 dichloroethene (DCE), trichloroethene (TCE), tetrachloro- ethene (PCE), and vinyl chloride, constituents found in groundwater throughout the Tutu Gut area. In addition, acetone, methylene chloride, chlorobenzene, and chloroform were also detected in some wells (Figure 11). The compound with the highest concen- tration in both deep and shallow groundwater was 1,2 DCE. Its concentration ranged from 43 to 280 ppb in shallow groundwater and from 270 to 520 ppb in deep groundwater wells under the site (Figure 11 and Table 4). HVOC concentrations in shallow monitor wells TT-1 and TT-4 may have been masked by interfer- ence of BTEX constituents. Total HVOC concentrations under the site were higher in the deep monitor wells than in the shallow wells (Figure 11). Concentrations in the deep wells ranged from 364 ppb (MW- 4d) to 825 ppb (TT-ld), whereas those in shallow wells ranged from 97 ppb (MW-4) to 423 ppb (TT-5). The total HVOC concentration in TT-6 in the Four Winds Shopping Center parking lot was 271 ppb. 34 Environment*!

IMPACTS The investigation of the unsaturated zone at the Texaco site focussed on impacts related to releases of petroleum product from the former UST pit site, and potential releases of oily wastes and HVOCs from various waste management units. The native soil under the site appears to consist of moderately plastic, sandy day to highly plastic clay. The underly- ing saprolith is composed of intensely weath- ered volcanic bedrock and has a high propor- tion of moderately plastic day matrix Field observations suggest that bom the soil and the saprolith appear to be capable of retarding ansport of heavier hydrocarbons. 6.1.1 PRODUCT RELEASES Soils in and around the former UST pit site appeared to be impacted by petroleum product-related constituents possibly due to product leakage from the original USTs or from related plumbing. BTEX concentrations were greatest in soils analyzed from 5 feet in TT-ld, but do not appear to extend below 10 feet in the affected area. The old UST pit and the area around it were previously excavated and replaced with gravelly clay obtained from an off-site source. This gravelly fill was also impacted by product that probably remained in the soil surrounding the excavation. The depth to bedrock in the area of the old UST pit is approximately 16 to 17 feet, which is at least 7 feet below the base of the excavated pit The bedrock underlying the TT- 1 well duster location is approximately 22 feet below the surface. The thickness of the saprolith at these locations ranges from 5 to 7 "eet Gasoline may have been able to penetrate ^_xhe saprolith and enter the fractured bedrock aquifer at this location because the saprolith may be more permeable to lighter hydrocar- bons than to heavier waste oil or water. HVOCs were dearly not released from the USTs. 6.13 WASTE MANAGEMENT UNITS All the waste management units at the site were inspected for structural integrity to determine their potential for release of con- taminants to the soil and underlying ground- water aquifer. None of the units have been in service since 1992. The three service bay sumps were drained and sediment shoveled out prior to inspection. Although an apparent breach was found between a wall and the concrete floor of the east service bay sump, soil sampling adjacent to this unit in SB-3 show that soils were not impacted from this breach. The middle service bay appeared intact, and its adjacent soil boring also free from impact. An underground water line leak near the west service bay may have facilitated release of heavy oil from a breach around the outlet pipe in that sump, but impact was limited to a few inches above the soil/saprolith contact. The saprolith itself did not appear to be impacted. Depth to bedrock at mis location is approximately 15 feet below the surface. The thickness of saprolith here is approximately 10 feet. The oil/water separator was visually inspected after deanout and found to be intact except for some deterioration of concrete around inlet and outlet pipes that run to the service bay sumps and infiltration gallery, respectively. A soil boring placed on the southwest (down-slope) side of this unit showed soil staining to a depth below the base of the separator, but no impact to the underly- ing saprolith. Bedrock at mat boring location is estimated at 17 feet below the surface, with at least 6 feet of saprolith below the impacted soil. The staining was probably the result of release of waste oil from the breached concrete around 39 Environmental Setf nee ana Enginasrmg ABOUtoumuonHCanptny ID t- Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands the inlet pipe from the west service bay sump, which may have migrated a short distance through the soil under the influence of water that was leaking from the underground water supply pipe. There is no evidence that the waste oil here has penetrated below to the saprolith. The interior of the infiltration gallery did not contain any fluid at the time of this investi- gation, and the walls of the unit appeared intact A total of five separate samples of sediment taken from the base of this unit were analyzed for VOCs, but no VOCs were de- tected in any of the samples. The base of the 'nfiltration gallery (10 feet below the surface) is ^oelow the soil/saprolith contact, which at this location is at approximately 7 to 8 feet below the surface. Depth to bedrock here is approxi- mately 14 feet below the surface, which is 4 feet below the known base of the unit There is currently no evidence that VOCs reside in the infiltration gallery, although low concentra- tions of petroleum hydrocarbon-related compounds were detected in previous sam- pling events by others (Geraghty and Miller, 1993a). No HVOCs were ever reported in wastewater samples from the infiltration gallery. The infiltration gallery was designed to allow wastewater to penetrate the saprolith. This may have carried low concentrations of petroleum hydrocarbon contaminants into ground water in the past. The septic tank was measured at 9 feet deep after it was drained of what appeared to be relatively dean water. No evidence of staining was found in the soil or saprolith in adjacent boring ST/SB-1, and analyses of soil from above the soil/saprolith contact did not reveal any detectable VOCs. Bedrock under this unit is approximately 13 feet below the surface, and the overlying saprolith is approxi- mately 6 feet thick. It does not appear this unit has ever contributed contaminants to the soil, saprolith, or fractured bedrock. Minor oil staining encountered in boring SB-6 was restricted to a very thin zone in the soil that directly overlays the saprolith. Con- taminants analyzed from the soil sample included ethylbenzene, acetone, 2-butanone, and carbon disulfide. It is likely that the ethylbenzene was derived from UST pit soils that were stockpiled at this location prior to their removal from the site. The soil here was excavated and replaced during installation of the municipal sewer hookup to the service station in 1992. The acetone and 2-butanone are most likely ambient (airborne) contami- nants that are common combustion products of auto engine exhaust, or laboratory contami- nants. Carbon disulfide is a common product of bio-organic emissions from soil. It was not possible to determine if this impact extended down into the underlying saprolith because it was not possible to site the drill rig over the hand-augered hole due to obstructions. How- ever, based on soil impacts observed in other boreholes where the saprolith was penetrated (e.g., UST area, OW/SB-1, SB-1), penetration of this impact through the sparolith in SB-6 is not expected. The saprolith here is approximately 7.5 feet thick. 6.13 WASTE On. DRUMS Soils beneath the former drum storage areas sampled by borings SB-4 and SB-5 did not appear to be impacted by any spillage waste oil drums. Laboratory analyses of composite samples from selected waste oil drums, collected by Arthur D. Little and split by GCL during the field investigation, are dominated by BTEX constituents, although one composite sample showed 133 ppm total HVOCs (1,1,1-TCAand PCE). Although these solvents may have been present in the small in o 40 Environmental Science and engineering * BOH Mtmnnna/ Comptny Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands quantities of commercial engine degreasers and solvents that may have been used at the site, there is no evidence that these compounds are present in site soils or the base course sand of the infiltration gallery on site. 6.2 GROUNDWATER IMPACTS 6.2.1 SUBSURFACE PERMEABILITY ZONATION Groundwater gradients in the vicinity of the Texaco site are strongly controlled by vertical fractures in the non-weathered, volca- nic bedrock, and are generally to the south inder the Texaco Tutu site (Figures 12a and ^i2b). The most transmissive fractures appear to be below the saprolith/bedrock contact Although static water levels in the new moni- tor wells are above the saprolith/bedrock contact, the saprolith appears to have low permeability and can probably be considered a semi-confining (i.e., leaky") layer. The onset of water production below the saprolith in the monitor well borings appears to confirm that the saprolith does not contribute significantly to the groundwater budget under the site. The lack of visible impact to the saprolith from waste oil releases at the site suggests that the weathered, clayey saprolith has low permeabil- ity and transmissivity to petroleum-related compounds. BTEX CONTAMINANT TRANSPORT Shallow and deep groundwater under the Texaco site have been impacted by BTEX contaminants, but BTEX contaminants are more prevalent in shallow groundwater wells at the site. The center of mass of the shallow water BTEX plume related to the release at the , Texaco site is confined to within 100 feet from the point of discharge (Figure 12a). BTEX constituents on the upgradient side of the Texaco site are present only as "J" values in TT- 2andMW-3. Benzene was the only BTEX constituent detected in groundwater in well TT-6, but its concentration there was 2 ppb benzene (a T value), which is below Federal standards of 5 ppb. Benzene concentrations above the 5 ppb standard are confined in the shallow aquifer to the area of the plume north of TT-6 (Figure 12a). BTEX constituents were not detected in deep groundwater on the upgradient side of the Texaco site in TT-3d, and are present only as "]" values in the adjacent shallow monitor well(MW-3). Deep BTEX contamination and benzene concentrations in excess of the 5 ppb standard in the deeper aquifer are limited to the area north of the Tillett supply well and centered immediately south of the Texaco site (Figure 12b). The current configuration of the shallow water BTEX plume in the area of the Texaco site reflects the strong influence of the Tillett supply well in containing the plume in proxim- ity to the point of release, after the release occurred and before cessation of pumping from that well. The original gasoline release was directed southward toward, and captured by, the Tillett well in response to past pumpage. Capture of the plume by that well inhibited downgradient migration of BTEX from the Texaco release to less than 400 feet from the point of release. This well probably provided additional degradation of the dis- solved phase contaminants by turbulent sparging along the producing fractures in the vicinity of the Tillett wellbore. The well is completed open-hole from 15 to 100 feet below the surface. Pumpage from this interval was adequate to cause migration and breakthrough of the plume at mis location, and vertical transmission of BTEX constituents deeper into the aquifer. After the Tillett well stopped 41 Environmental Science *ng Engineering A 8QM InHmuorul Comptny \Ti j-3I- Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands pumping, the plume remained relatively stable and more concentrated near the source Impacted soils around the old UST pit may have provided a low-level, continuing source of additional hydrocarbons after the UST pit was excavated and closed. 623 HALOGENATED VOLATILE ORGANIC COMPOUND CONCENTRATIONS AND SOURCES HVOCs were detected in shallow and deep ground water monitor wells at the Texaco site. Total HVOC concentrations are higher in the deep versus the shallow monitor wells "^igure 11), indicating a moderate, downward ertical gradient under the site. The highest concentration of these compounds in the shallow zone were found in TT-5 on the east side of the site, whereas the lowest total concentration in shallow water was found in MW-4, downgradient from the oil/water separator and infiltration gallery. Concentra- tions of chlorinated organic compounds are higher in deep ground water wells. The highest concentrations on site were found in TT-3d and TT-ld (809 ppb and 825 ppb, respectively), and diminish in MW-4d (364 ppb) upgradient from TT-ld (and downgradient from the oil/ water separator). It is likely that the primary sources) of HVOCs is from east and possibly north of the Texaco site, and that these constituents mi- grated vertically down through the aquifer as they advanced downgradient from the source(s), producing higher concentrations at depth. A vertical downward groundwater gradient has been documented in the upper Turpentine Run area (Geraghty & Miller, 1993a). If HVOCs had been derived from the Texaco site, it would be expected that higher concentrations would be found in the shallow aquifer under the site than in the deep aquifer. The lack of any soil source for HVOCs on the Texaco site further indicates mat these com- pounds were not derived from this site, but migrated into groundwater under the site from an off-site source(s). 42 Environmental Science ana Engineering 4 BOM Inttmmxul Comptny Phase I Remedial Investigation Report St. Thomas, U.S. Virgin Islands 7.0 CONCLUSIONS The results of GCL's first phase investiga- tion and analyses of sample splits of waste oil drums and the infiltration gallery at the Texaco Tutu service station show that • BTEX compounds are the only constitu- ents detected in soil samples. These constituents are associated with residual contamination from the gasoline dis- charges from the old UST pit and minor breaches in one service bay sump and the oil/ water separator. BTEX constitu- ents include benzene, ethylbenzene, and xylenes in soils dose to the old UST release point Only ethylbenzene is found in soils near the waste manage- ^ ment units. • HVOCs were not detected in any soil samples on the site or samples recovered from the bottom of the infiltration gallery. • Other VOCs detected in soils, which include acetone, carbon disulfide, and 2-butanone, are most likely ambient (airborne) and/or laboratory contami- nants. • HVOCs were found in one waste oil drum composite sample and may be related to commercial solvents used in small amounts at the site. However, no HVOC compounds were detected in on- site soils, including soils under the drum storage areas. BTEX found in ground water north of TT- 6 appears to be attributable to release of gasoline from the old UST pit and associated piping at the Texaco service station. Bedrock structure and vertical fracture systems directed most of the release to the south. Natural processes of volatilization and biodegradation effectively attenuated • BTEX after less than 400 feet of transport downgradient, aided by pumping and suspected induced sparging in the Tillett supply well when it was still in opera- tion. Contamination in excess of 5 ppb ben- zene extends to a depth of approximately 53 feet below land surface (TT-ld), but is limited to the area north of the Tillett supply well. Deep contamination was not detected down to a depth of 53 feet upgradient on the site (TT-3d). HVOCs observed in groundwater at the site are from sources upgradient of the Texaco site. 43 Environmental Science and Engineering Convoy Phase I Remedial Investigation Report St Thomas, U.S. Virgin Islands 8.0 REMEDIATION STRATEGY This investigation demonstrates that the HVOCs (CERCLA wastes) observed in ground- water beneath the site originate from off-site sources and that HVOCs are not present in site soils. We understand that a CERCLA remedial action is being conducted to address HVOC contamination of groundwater in the area, including the groundwater beneath the Texaco Tutu site. A proposed CERCLA remedial technology that addresses HVOCs may also mitigate the VOCs (petroleum hydrocarbons) that originate from the Texaco Tutu site. This possibility was considered during the develop- ment of the remediation strategy for the Texaco Tutu site. ^ This report also concludes that the petroleum hydrocarbon groundwater plume emanating from the Texaco Tutu service station is stable and not migrating further downgradient. Thus, there is no immediate need to remove these petroleum hydrocarbons in groundwater in areas off site. GCL proposes to implement a remedial strategy on site. This remedy can be integrated with whatever remedial strategy is selected for the forthcom- ing CERCLA action. GCL proposes soil-vapor extraction technology to remediate hydrocarbon contami- nation associated with the Texaco Tutu site. The vapor extraction system for the Texaco Tutu site will remove hydrocarbons from the soils of the source area (former UST site) and the groundwater plume center-of-mass. System operation is flexible, and will allow field modifications according to the responses observed during the initial period of operation. These modifications will be made in order to optimize the effectiveness of the system in removing hydrocarbon mass. 44 8.1 SYSTEM DESIGN PARAMETERS The ultimate goal of operating a soil- vapor extraction system for the Texaco Tutu site is to remove petroleum hydrocarbons from on-site soils and underlying groundwater. The system presented in this section is designed to remediate hydrocarbon-bearing soils in the vicinity of the former UST pit, and dissolved- phase hydrocarbons in the groundwater underlying the southern portion of the site. Hydrogeologjcal assumptions and conditional parameters taken into consideration for this proposed system include: • Groundwater flow is generally to the south. The flow is controlled by major fractures in the bedrock and pumpage from area water wells. • The most transmissive fractures are below the saprolith/bedrock contact, based upon the onset of •water produc- tion observed during the drilling of the monitoring wells. • BTEX concentrations are higher in the shallow zone groundwater (30 feet or shallower) than the deeper zone ground- water by more than an order of magni- tude. • Upgradient wells show little impact of BTEX constituents, but contain solvent contamination from an off-site source(s). • The remedial system must not induce further migration of off-site chlorinated solvents contained in groundwater onto the site. • The day-rich soil and interstitial clay in the saprolith may limit the effective radius of influence of the soil-vapor extraction system. go •3- h- Envimnmerual Science ami Engineering A BOM Innmmontl Comp*ny Phase I Remedial Investigation Report St. Thomas. U.S. Virgin Islands GENERAL PRINCIPLES OF VAPOR EXTRACTION Vapor extraction technology refers to the use of forced air ventilation of soil to remove VOCs that vaporize from the soil into the moving air stream. Vapor extraction can be used to treat soil VOCs in situ or ex situ. successful use of this technology in situ is dependent on having a thorough understand- ing of site hydrogeology and chemical distribu- tion. For in situ soil-vapor extraction, VOCs are removed under vacuum from recovery wells screened in the vadose zone and monitor wells that span the vadose-groundwater ^rface, and removed from the soil by the off-gases. Soil-vapor extraction at the Texaco Tutu site is constrained by the presence of day-rich soils and underlying saprolith. However, on- site soil contamination is spatially limited. The highest concentration of BTEX constituents in the soils are located in the vicinity of the old USTpit. The pit area was excavated and replaced with gravelly clay. The fill material in this area provides a more porous media for soil venting. Soil venting is considered to be appropriate at this location due to the flexibil- ity of the proposed system. From past GCL experience with other soil-vapor extraction systems applied to sites with similar soil characteristics and contamination, reducing the moisture content in the vadose zone wfll significantly increase the air permeability. Held studies indicate that as water saturation in the vadose zone drops below 50 percent, the relative air permeability increases. The reduc- tion in soil moisture at this site will gradually increase the air permeability of the days due to ying and desiccation. The radius of influ- ^_^ce for extraction wells will gradually in- crease over time as the system operates. In addition, with the dual purpose venting wells, this drying-out process of the clays can be directed to specific areas of impact. 8.3 CONCEPTUAL DESIGN FOR THE TEXACO TUTU SITE Based upon the results of GCL's field investigation, hydrogeological models per- formed by other consultants, and other investi- gations performed at this site, we propose an in situ soil-vapor extraction system for the site. This technology produces a remediation system that will result in rapid, cost-effective cleanup of the Texaco Tutu site. 83.1 SPECIFIC DESIGN ELEMENTS The system will draw soil vapors from the southern portion of the Texaco site, an area that displays the highest concentrations of BTEX constituents at the site. The system will consist of a sub-grade conduit that connects the existing monitor wells TT-1 and TT4 with the vapor extraction unit (Figure 13). A3-horse- power vapor extraction unit will provide the pressure gradient and extraction rate necessary for optimal system efficiency. The delivery lateral, constructed with 2-inch schedule 40- PVC, will connect the monitor wells to the vapor extraction unit. The delivery lateral, gauges, and associated sensors will be placed in an 8-inch diameter corrugated aluminum pipe, which will provide protection and permit installation of other piping, if required, for system design flexibility. The corrugated pipe and lateral will be installed in a sub-grade trench running northward from TT-1 to TT-4. The piping will extend eastward from TT-4 to the eastern wall of the site. The piping will be brought above surface from that point and run northward to the northeastern corner of the property and to the extraction unit The vacuum extraction system will be installed at 45 Environmental Scifnce ana Engineering A BOM toumttion* Company Phase I Remedial Investigation Report St Thomas, U.S. Virgin Islands this location due to proximity to power lines. The system will also have a water knockout tank to collect water vapor generated by the system. The monitor wells will be fitted with downhole sensors to prevent water from rising above the screened interval in the wells. When water rises to within one foot of the top of the screen, a bleeder valve win be activated to allow ambient air into the well. The bleeder valves will prevent overheating of the vapor extraction motor and provide a more efficient and reliable system. Four drive points will be installed at 20- *et intervals between TT-1 and TT-4, and 'eastward from TT-4 to the eastern property line (Figure 13). The drive points will act either as vapor extraction or air inlet wells for the vadose zone underlying the southern portion of the Texaco Tutu site. The drive points will be constructed of 2 or 4-inch diameter steel casing. They will have five feet of 0.020- to 0.060-inch screens at the lower portion of each point. The drive points will be installed to a depth of between 8 and 10 feet, and will be above the water table. The drive points will provide multiple functions, and be fitted with three-way valves. The three-way valves will allow these points to act as observation points, vapor extraction wells, or passive venting wells, depending on system needs. Vacuum gauges installed on the points will measure the radius of influence of the vapor extraction wells TT-1 and TT-4. The drive points will also be connected to the extraction system, with the exception of drive point 4 (which will be used for observation and passive venting only), and will be utilized to extract vapors from shallow site soils. The three-way valves will also allow the drive points to be disconnected from the system. All of the drive points may be utilized as passive venting wells and vacuum observation wells, depending on need. Drive points 1,2, and 3 may also be used as vapor extraction wells. Installation of the system will be followed by a start-up/prove-out test to determine the radius of influence of TT-1 and TT-4, evaluate the efficiency and volume of vapors extracted by the system, and ensure the system can be remotely operated. The initial test, which will test extraction well TT-4, is expected to take a minimum of 72 hours. Vapors generated by the system will be closely monitored to ensure compliance with air quality standards for the U.S. Virgin Islands during system operation. 833. SYSTEM OPERATION After the initial testing of TT-4, the system will be adjusted for maximum effi- ciency. Primary extraction wells TT-1 and TT-4 will be used to their full extent to address the contamination located in the soil at these locations. Drive points 2 and 3 will also be used as extraction wells to increase the radius of influence and allow maximum application of the vacuum extraction unit. Drive points 1 and 4 will operate in the passive venting mode to augment the volume of induced air being 46 Environmental Science and Engineering Company 6" HIGH PROTECTIVE WALL SB-6 — ——— -4 EXISTING CONCRETE BLOCK GARBAGE BIN PROPOSED SVE SYSTEM SIGN LEGEND EXISTING MONITORING WELL SHALLOW MONITOR WELL DEEP MONITOR WELL SOIL BORING PROPOSED DRILL POINT W/ 2" WELL CASING 5-FOOT SCREEN OBSERVATION WELL PASSIVE VENTING WELL VAPOR EXTRACTION WELL CONCRETE CULVERT STORM WATER DRAIN SEPTIC TANK c.o.

If necessary, drive point 1 can also be used as an extraction well, if the air permeability of the soil is less than predicted. The efficiency and radius of influence of the system at a given time can easily be determined by switching the dry wells to the observational mode, allowing the system to equilibrate, and measuring the pressure drop at these points. 833 MONITORING The results of the initial test will allow the system network and pneumatics to be ad- justed, as required. This system will allow area-specific remediation efforts, as deemed necessary. For instance, if vapor monitoring of the drive points indicates that the northeastern portion of the soil plume is mitigated to below field detection limits, drive point 3 will be switched to observational mode, and more vacuum (thus, more vapors) will be extracted from the areas surrounding TT-1 and drive points 1 and 2. An Operations and Maintenance Plan will be developed after installation has been completed. 48 Environments!

Reagent or analytical blanks are analyzed to assess the level of contamination which exists in the analytical system. An analytical blank, analyzed with every batch of samples, consists of reagents specific to the method. This blank is carried through every aspect of the procedure, including preparation, cleanup, and analysis. Ideally, the concentration of an analyte in the blank is below the reporting limit for that analyte. However, some common laboratory solvents and metals are difficult to eliminate to the part-per-billion levels commonly reported in environmental analyses. Duplicate control sameles (DCS) are used to monitor the laboratory's day-to- day performance of routine analytical methods. A DCS consists of a standard, control matrix which is spiked with a group of target compounds representative of the method analytes. The DCS is analyzed with environmental samples to provide evidence that the laboratory is performing the method within accepted QC guidelines. A DCS has been established for most routine analytical methods. Reagent water is used as the control matrix for the analysis of aqueous samples. The DCS compounds are spiked into reagent water and carried through the appropriate steps of the analysis. As stated in SW-846 (third edition), a universal blank matrix does not exist for solid samples and therefore no matrix is used. The DCS for solid samples consists of the appropriate steps of the analysis. The data thus obtained are used to set the DCS control limits. The control limits for accuracy are based on the historical average recovery of the DCS plus or minus three standard deviation units. The control limits for precision are based on the historical relative percent difference (RPD) and range from zero (no difference between duplicate samples) to the average RPD plus three standard deviation units. Surrogates are organic compounds that are similar to the analytes of interest in chemical behavior but which .are not normally found in environmental samples. Surrogates are routinely added to samples requiring GC/HS analysis to monitor the effect of the matrix on the accuracy of the analysis. Results are reported in terms of percent recovery. TUT OO5 16O8 ANALYTICAL RESULTS The method number provided on each data report sheet refers to a publication originating from a regulatory or standard-setting organization. In general, the methods employed are those specified by the U.S. Environmental Protection Agency and other state and federal agencies. In cases where an approved regulatory method does not exist, a method developed by Enseco will be employed to meet the specific needs of the client. The methods commonly employed by Enseco are based on methods from the following references. U.S. Environmental Protection Agency. Methods for Chemical Analysis of Water and Wastes. EPA-600/4-79-020. Cincinnati, OH, March, 1993. U.S. Environmental Protection Agency. Test Methods for Evaluating Solid Waste. Physical/Chemical Methods (SW-846). Washington, D.C., November, 1986.
