This veil was used as a main source of drinking water supply on the eastern portion of the island. Subsequently, samples were taken from 6 additional wells which service residential customers in the immediate area. Eventually a total of 24 wells; 14 commercial, 6 private, 3 institutional and 1 public in the Tutu area, were sampled and analyzed. Also, a total of 123 cisterns serviced by water haulers from this area were sampled and analyzed. Analytical results showed 3 wells with contaminants above the 175 ppb Health Advisory level for PCE and 8 wells above the recommended maximum volatile organic compound (VOC) levels in drinking water. Twenty four (24) well samples showed the presence of 1-2-transdichloroethylene (DCE), trichloroethylene (TCE), tetrachloroethylene (PCE), toluene (TOL), benzene (BEN) and tertbutyl methyl ether (TBME) in concentrations ranging from 61 parts per billion (ppb) to 120,000 ppb. Based on these results, 13 commercial and 5 private wells were ordered closed. Also, 5 cisterns were found to be contaminated. These cisterns were cleaned, disinfected and filled with high quality drinking water. EPA also conducted a Hazardous Substance List (HSL) analysis on the twenty four (24) wells to confirm the previous analyses. Results of this latest HSL testing showed the presence of additional metal contamination. Three (3) of the wells tested, showed high VOC and metals concentrations such as arsenic (15 ppb) selenium (15 ppb) and zinc (340 ppb). Based on prior sampling results, EPA initiated a limited CERCLA removal action by providing water truck deliveries to fill three cisterns. The three cisterns serve an estimated 50 persons in two homes and one apartment complex. On December 3, 1987, EPA initiated a study to consider various alternatives to find a safe and permanent potable water supply for the affected homes. The initial phase of the study is contained herein. 1.2 Conclusions and Recommendations In order to provide a permanent water supply to the two ^ three family homes and one apartment building housing "* twelve studio units; the EPA had considered the -1- following alternatives: no action; extend the existing water main; install new and deeper wells within the contamination area; install new wells beyond the area of contamination; install a whole house reverse osmosis unit at each location; construct a reverse osmosis central plant; construct a water treatment plant; increase the capacity of the cisterns; and install individual activated carbon filters. The Virgin Islands Housing Authority (VIHA) received a grant from the Federal Housing and Urban Development (HUD) to extend a water main to serve the Bovoni housing project, this water main has been constructed. EPA will connect two laterals to the existing water main, one, a 2 inch diameter polyvinyl chloride (PVC) pipe, to service Messrs. Steele and Harvey and the second, a 6 inch diameter ductile iron pipe (DIP) to serve Ms. Smith. The cost for these laterals, including a fire hydrant on the 6 inch pipe as required by the Fire Code is $220,000. 2.0 SITE DESCRIPTION AND CONDITIONS 2.1 Site Background and Conditions The Tutu Well site is located at the eastern end of the Island at the Anna's Retreat Section of St. Thomas (see Figure 2-1 page 3. Most of the wells are used for public drinking water supply. On, or about July 7, 1987, Mr. Eric Tillett, contacted the DPNR regarding an odor emanating from the raw well water on his property located at Anna's Retreat, St. Thomas, USVI. On July 16, 1987, the EPA received a request from the DPNR in St. Thomas, for sampling and analyses of several wells in Tutu. On July 21, the EPA and its Technical Assistance Team (TAT) contractor, Roy F. Weston, Inc., mobilized to St. Thomas, to perform sampling on the drinking water wells suspected of being contaminated. These wells were also reported to have a strong, unpleasant odor and were found to be contaminated with hazardous substances and petroleum products comming from two gas stations in the Tutu area. The EPA and TAT in coordination with DPNR, initiated sampling of wells in the affected area in July 1987. The test results showed the presence of high concentrations of gasoline and chlorinated organic compounds. Seven wells: Elgin, Four Winds, Harthman, and VIHA were closed down by order of DPNR due to high VOC concentrations. -2- FRENCHMANS BAY SP!U PREVENTION & EMERGENCY RESPONSE DIVISION In Association with ICF Technology Inc.

THOMAS U.S. VIRGIN ISLAND Several of the wells in this area are major commercial well services used for public drinking water supply; therefore, the incident was classified as major, and the DPNR Commissioner requested the EPA to assume the role of Lead Agency. The well locations can be seen in Figure 2-2 page 5 . A Texaco station, located opposite the Tillet Well, is suspected as a possible source of contamination. A Petrotight test conducted on the underground storage tanks at this facility indicated leaks in two of the three tanks. These failures may have contributed to the groundwater pollution problem, resulting in the contamination of nearby wells. Another suspected source of contamination is the Tutu Esso gas station. This facility uses and stores waste oil in an underground storage tank. The facility has had problems in the past with leakage from their underground gasoline storage tank and is suspected of using solvents in the mechanic shop. At the time of inspection, the nature of the problem had not been determined. Another suspected origin of PCE contamination is the O'Henry Laundromat. In Septeber 1988, an EPA contractor obtained three soil samples at this facility, the composite of these samples showed 440 ppm of PCE. EPA continued its efforts towards the identification of; affected wells in the area, customers which had received water from contaminated wells, and possible alternate water supplies and remedial action alternatives. A testing program of wells located outside of the known area of contamination was conducted to evaluate those areas as possible alternate water supply sources. Sampling of cisterns served by the contaminated wells was also performed. EPA directed the Emergency Response Cleanup Services contractor (ERCS) to; clean and disinfect the five (5) cisterns which had tested positive for PCE, modify the existing home plumbing, disconnect the contaminated wells, and dispose of the contaminated water. At EPA's direction, ERCS also contracted a local water hauler to deliver uncontaminated drinking water to the cisterns by tank truck. A well sampling program was established by the EPA to monitor the wells at the Tutu site for a one year period. , -4- •1-4 .13.2 « 3.3- 3.2' 3.1 • NO. WELL NAME NO.

FIGURE 2-2 WZLL LOCATION MAP TUTU ST. THOMAS U.S. VIRGIN ISLAND 2.2 Sampling Results The Tutu well site has been sampled repeatedly over the last two years and found to contain definite con- tamination. The initial assessment was conducted in July through September of 1987. Subsequent sampling and analysis has proceeded on a regular basis. The initial assessment considered 24 wells and approximately 50 cisterns, of which 24 wells and 5 cisterns were found to be contaminated. The 5 cisterns were cleaned and disinfected by the ERCS contractor. Subsequent monitoring has been considered for the 24 wells that showed some type of contamination. Table 2-1 pg. 16, lists the wells included in the current sampling program. Tables 2-2 and 2-3 , pages 17 and 19, show the volatile organic analysis results of the contaminated wells and give the highest concentration of organic contamination found during the last six months. The sampling, and most of the preliminary Photovac portable GC screening was conducted by the U.S. EPA Region II TAT. Certified drinking water laboratories have performed formal analyses to verify the Photovac screening results and to cover the entire spectrum of possible hazardous contaminants. Although, the concentration of these contaminants fluctuates monthly, it is noteworthy that the major contaminants have been DCE, TCE, PCE, TOL, BEN, TBHE and various metals. Their high concentration in four wells; Tillet, Harvey, Smith and Steele has been evident from the initial assessment. These wells show concentrations of VOC in excess of 1,000 ppb. The major and most consistent contaminant appears to be PCE. The Tillet well has also shown very high DCE and BEN contamination. Four other wells; Francois, Mathias, Four Winds, and Elgin; were confirmed to have >50 ppb VOCs. The last confirmation analysis conducted during October 1987, included the entire Hazardous Substance List (HSL) consisting of approximately 150 chemicals. At that time, significant levels of TBME up to 470 ppb, and methylene chloride up to 120,000 ppb were detected. Some samples have also shown traces of vinyl chloride, chloroform, 1,1,1-trichloroethane, bromodichloroethane, xylene, and ethylbenzene. -6- Finally, the HSL analysis also showed the presence of EP toxic metals. The report showed the presence of eight distinct metals in some of the wells examined See Table 2-4 page 21. Zinc was the most abundant element detected at a level of 460 ug/1. Selenium was also measured in two wells (VIHA #1 and Steele) at concentrations exceeding the Primary Drinking Water Regulations (PDWR) limit of 10 ug/1. In summary, the Tutu Wells Site monitoring has indicated persistent contamination in the well drinking water and the need for immediate remediation. 3.0 DRINKING WATER STANDARDS 3.1 EPA Regulations The Safe Drinking Water Act of 1974, and amended in 1977, established primary and secondary drinking water standards. The primary standards were established to protect public health, while the secondary standards mainly addressed the physical characteristics of drinking water such as taste, odor, color and corrosivity. See Tables 3-1, 3-2, and 3-3, pages 22 and 23. The Maximum Contaminant Level (MCL) and the Recommended Maximum Contaminant Level (RMCL) were developed by the EPA Office of Drinking Water to provide acceptable concentrations of specific organics and inorganics in public water supply systems. RMCL's are contaminant levels at which there are no known or anticipated adverse health effects to a human being. MCL's are enforceable health standards that are set as close to the RMCL's as feasible based upon practical considerations such as treatment technology, cost, analytical methods and detection limits. Removal Action Levels (OSWER Directive 9360.1-10) Under the 1982 National Contingency Plan (NCP), removal actions were taken in response to "immediate and significant" threats to human health or the environment. The removal program used the 10-Day Health Advisory as the principal benchmark to identify those drinking water contamination incidents that posed the most acute threats to human health. The November 1985 NCP broadened removal authority by authorizing response in situations that present a "threat" to human health or the environment. Therefore, removal actions may now be taken in less urgent situations than under the 1982 NCP. -7- i in The action level for nethylene chloride, for example, is calculated as follows. Methylene chloride is a volatile and a potential human carcinogen (classified as a "B2M under EPA guidelines). The DWEL for nethylene chloride equals 1750 ppb and the 10~4 Cancer Risk Level equals 48 ppb. The action level is determined by comparing 50 percent of the DWEL, or 875 ppb, to the 10~4 Cancer Risk Level, or 48 ppb, and choosing the lower of the two, which is 48pp6. The following is a summary of the maximum concentrations of the primary pollutants found in the contaminated wells and the statutory source for their designation as a hazardous substance under CERCLA.

See table 3-5 page 26 for other maximum contaminant levels established in the USVI. 4.0 PROPOSED ACTION The VIHA received a grant from the HUD to extend a 12 inch dia. watermain to the Bovoni Housing Project. This watermain has already been constructed. The proposed action is to connect two laterals to the existing 12 inch dia. watermain and tie in Messrs. Harvey, Smith and Steele.

HAFItER FIGURE 4-1 EPA PROPOSED LATERAL CONNECTIONS TUTU, ST. THOMAS U.S. VIRGIN ISLANDS 4.1 Project Scope The scope of this project would be to install approximately 1000 feet of 2" PVC pipe from the existing 12" main along the roadway leading to the Harvey and Steele homes. The Harvey and Steele cisterns would then be connected to this 2" line using 3/4" copper tubing. The cistern at the Smith residence will be connected top the 6 inch lateral using 3/4" copper tubing. Water meters will be installed at each residence and the existing contaminated wells will be capped. 4.2 Detailed Costs The detailed costs for the connection to the existing 12" diameter water main, were based on average daily production rates for the various tasks taken from the Means Construction Cost data book and from TAT conversations with USVI Officials and one contractor. The estimate provides for funding to the engineering company for the survey, profile drawings, piping design for the Route 32 Circle, checking of existing pipe drawings and specifications. The costs assume that the laterals, the 6" dia. pipe will be ductile iron pipe, cement lined, class 250; and that polyvinyl chloride 2" dia. pipe will be installed from the water main up to the house cisterns at Steele and Harvey, house connections will be made as per current WAPA specifications and will include water meters. It is further assumed that the PVC pipe will be installed concurrently with the 6 inch DIP installation. Pipe fittings, disinfection, trenching, filling, com- paction and road restoration are included in the in- stallation costs per linear feet of pipe. Project costs for this work is summarized on the following pages. -11- Project costs for the installation of a 6 inch diameter ductile iron pipe (DIP) to the Smith's residence and a 2 inch diameter plastic (PVC) pipe to the Steele's and Harvey residences, including the three houses (cisterns) connections. The costs are based on a 12 hour day and 5 days per week (60 hours/week). Length of pipe installed per 12 hour day: 100 L.F. of 6" diameter DIP, 175 L.F. of 2" PVC pipe. I. EXTRAMURAL COSTS A.

The figure shows a total of five (5) weeks of scheduled tasks. Two weeks (10 days) of the schedule have been allocated to the survey, profile drawings, specifications and permits. Two additional weeks will be used installing the 6 inch diameter DIP and the 2 inch diameter PVC pipes, including excavation, backfill and resurfacing of the road. The last week will be assigned to the disinfection of the installed water main laterals and the three house connections. TAT will be in St. Thomas during the five weeks. During the first two weeks, TAT will be making certain that the appropriate permits are obtained, while directing the work of the engineer. During the last three weeks, TAT will be monitoring the contractor. -14- FIGURE 4-2 PROPOSED WORK SCHEDULE (WEEKS) 0 Survey, Prep. Of Drwgs & Specs.

SITUATION; A. On July 16, 1987, the U.S. EPA received a request from the Department of Planning and Natural Resources (DPNR) [(formally known as the Department of Conservation and Cultural Affairs (DCCA)] St. Thomad, Virgin Island (VI) for analytical support in the sampling of several wells which were reported to exhibit a strong unpleasant odor. The wells, several of which are major well services used for distribution of the public drinking water supply, are located on the eastern end of the island in the Tutu section of Annas Retreat St. Thomas, VI. B. The sources of contamination is as of the present unknown. A suspected source is a local Texaco Station which had exhibited poor storage practices in the past. A petrotight test was conducted at this service station in the early part of July resulting in the failure of two of three tanks. Further information on the extent of tank leakage has not been forwarded to the DPNR or the U.S. EPA UST Program Director. 2. ACTION TAKEN: A. On July 21, 1987, U.S. EPA and their Technical Assistance Team contractor Roy F. Wtston, Inc. responded to the VI to assist the DPNR in veil sampling and provide analytical services to determine the extent of contamination. B. On July 22, 1987, samples from six veils vere collected and sent to a laboratory in Nev Jersey for volatile organic analysis and total organic carbon content. C. No product was discovered in the veils, therefore, no fingerprinting analysis could be performed by the USCG Coil Laboratory* D. On Thursday, July 23, 1987, DPNR held a aeetlng vith Texaco, to discuss an implementation schedule and vork plan for the Texaco Station. Cause Codes: (M) - Tank failure (C) - Lack of indicator/detection equipment 3. FUTURE PLANS AND RECOMMENDATIONS; A. U.S. EPA vill forward sample results to DPNR as soon as they are received. B. DPNR vill formally notify Texaco in writing as to the proper cleanup practices to initiate at this site to ensure compliance with VI and Federal regulations.

USEPA arrived on St. Thomas and met with Commissioner Smith of the Department of Planning and Natural Resources (DPNR) to coordinate the weeks activities and to exchange information on the status of work accomplished from the prior week. GO',' -2- B. Commissioner Smith of DPNR issued an order to Texaco Caribbean, Inc. to cease tank removal activity at the Tutu Texaco Service Station located at Anna's Retreat. This order refrained the removal of tanks, soil, and/or any activity which would disturb the immediate area. Tuesday, July 28, 1987 C. USEPA received the preliminary results from the sampling conducted on July 22, 1987. D. USEPA met with Commissioner Smith and DPNR staff to discuss results of the sampling and to establish the next phase of activities to be accommplished. Wednesday, July 29, 1987 E. At 1000 hours, USEPA and DPNR met with Texaco to discuss the necessary sequence of events with must be met prior to initiating excavation at the Tutu Texaco Service Station. F. USEPA met with Commissioner Smith and DPNR staff to commence the development of the modified order to Texaco to include a Safety Plan, Sampling Plan, Action Levels and the assignment of an Operations Coordinator to work with EPA and DPNR to assure all local and federal regulations are complied with. C. At 1000 hours, a hearing was held at the DPNR office. Representatives from DPNR, USEPA^Texaco and Tutu Water Supply were in attendance. The hearing was held to ensure that Texaco was in full understanding of the order issued on July 27, 1987 and its restrictions. Texaco stated during the hearing they would fully comply with local and federal regulations and would cooperate with DPNR. The Commissioner announced a modified order would be forthcoming with regard to the specificity of the requirements of the first order. H. USEPA and DPNR became aware of another Texaco Service Station (Reese) located at Harwood Highway which was in the process of excavating tanks and installing new tanks due to a failed petro-tight test conducted earlier in July, 1987. Apparent local and federal regulations were violated during the inspection. The acknowledgement of apparent violations led to a meeting scheduled for Thursday morning between USEPA, DPNR and Texaco. Thursday, July 30, 1987 I. At 1000 hours, a meeting was held at the DPNR office. Representatives from DPNR, USEPA and Texaco were In attendance. At this time, EPA requested Texaco, Corp. be notified of these concerns which were substantiated by the lack of compliance with Virgin Islands regulations displayed at numerous sites on St. Thomas. Friday, July 31, 1987 J. EPA and OPNR contact well owners Tillett, Harthman, Eglin and Four Winds to discuss sampling results. A request for customer names who purchase their water was made. Each well owner was notified of the excess MCL levels of trichloroethylene found in their wells. K. DPNR issued an order to Mr. Eric Tillet, President of Tutu Waters to close the Tillett well until further notice. L. Commissioner Smith verbally requests USEPA to assume the lead on the contamination problem in the Tutu area. M. EPA recommended DPNR to compile the following: an inventory of all wells both private and commercial, and all underground storage tanks in the Tutu area. 3. FUTURE ACTION: EPA returns to St. Thomas to undertake the contamination problem in the Tutu area and to assume the role of lead agency.
