&EPA UNITED STATES ENVIRONMENTAL PROTECTION AGENCY NATIONAL PRIORITIES LIST _OERR Hszaroous_Site S'/auaopr. Oivtsior. Wasriington DC 2046C TUTU WELLFIELD Tutu, Virgin Islands The Tutu Wellfield site involves a plume of contaminated ground water covering approximately 108 acres in Tutu in a mountainous semi-rural area of eastern central St. Thomas, U.S. Virgin Islands. In July 1*87, a svroug petroleum odor was detected in (he 'fillet Well, a public supply well in the area. At the request of the Virgin Islands Department of Planning and Natural Resources (VEDPNR), EPA sampled over 100 wells in the area. Volatile organic compounds such as benzene, toluw;, frans-1,2-dichloroethene, trichJ.->'iethene (TCE), and tetrachloroetheDe ("P<"F) were detected in several public supply, institutional, commercial, and private wells. Water from several commercial wells iii this area was hauled to other parts of the island. The Tillet Well, three private wells, and 13 commercial wells subsequently closed down, and alternative sources of water, including trucking water to the area, were made available. In July and September 1987, VIDPNR issued Administrative Orders on Consent to Tutu Texaco Service Station and Tutu Esso Car Care Center to investigate the release of petroleum from their underground storage tanks (USTs). In August 1987, EPA identified seven more potentially responsible parties (PRPs); one other gasoline service station (Rodriguez Auto Parts), two vehicle maintenance repair stations (Ramsay Motor Co. and Consolidated Auto Parts/Gasset Motors), two Territorial government agencies (vi.p". To' ->ds Housing AuAcrff; -::'' Departme.-.' :r r-•'.;• cat:'"::.. formerly the Lags P-vH^g" .? dry cleaner (O'Henry Cleaners), and a silk screening operation (Jim Tillet, Inc.,Tillet Gardens). Potential sources of hazardous substances at these locations include petroleum and waste oil USTs, drum storage areas, contaminated catch basins, oil separators, floor drains, a sump holding tank, a leaching pit, above-ground tanks, and an evaporation pit. Wastes that may have been disposed of include solvent-based auto flushes, treatments, degreasers, cleaners, and lubricants; antifreeze; kerosene; hydraulic fluid; waste oils; spent PCE waste and filters; dry cleaning fluids such as 2-butoxyethanol, hexylene glycol, and dye stripper; ammonium hydroxide; and mineral spirits. In September 1987, EPA used CERCLA emergency removal funds to decontaminate five residential cisterns, provide alternative water supplies, and monitor local wells. Since August 1987, EPA has detected many of the same chemicals found in drinking water wells in the soils on the properties of several of the PRPs. Semivolatiles such as phenols and polyaromatic hydrocarbons were also detected at a few of these properties, as was cadmium. An estimated 1,600 people formerly obtained drinking water from public and private wells within 4 miles of the site. In March 1990, EPA issued a unilateral Administrative Order to O'Henry Cleaners, Esso Standard Oil Co.. and Texaco Caribbean, Jar »o take over EPA's removaJ action. Tn September 1990, the three companies began the monitoring program and arranged with the Virgin Islands Housing Authority to extend water lines to owners of the four contaminated pnvate wells. Tufu js lorjsted JB the Upper Turpentine RUT; Basin. An intermittent stream leading to Turpentine Run is within a few hundred feet to the southwest. Turpentine Run flows southward approximately 2.8 miles to Mangrove Lagoon, which is hydraulically connected to the Caribbean Sea. The Atlantic Ocean lies approximately 1 niile to the north.__ — • _ (Tht description of the siu (release) Is based on information available at the time the site was scored.
