Ceechuu Cecchuu, and C,iovannom, Fueling Island <br /> A trip blank consisting of deionized water was provided by the ESE laboratory as a check <br /> on sample handling procedures The trip blank accompanied the samples to the <br /> laboratory The ground water samples from UST-2 through UST-5 were analyzed at the <br /> laboratory for <br /> 0 Total Petroleum Hydrocarbons as diesel (TPH-D) using EPA Method <br /> 3550/8015 Modified, and <br /> o Total Petroleum Hydrocarbons as gasoline (TPH-G) using EPA Method <br /> 5030/8015, and <br /> 0 Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) using EPA Method <br /> 5030/8020 <br /> The trip blank was analyzed for BTEX <br /> 4e0 Findings <br /> 4.1 McRd ®bseTvations <br /> On June 13, 1996, ESE observed that the concrete apron for the well box for well UST-1 <br /> had sunk slightly in an area of broken concrete The remaining ground water monitoring <br /> wells appeared in good condition ESE noted that the interior of well UST-1 was clean <br /> and free of surface leakage and that the sealing plug was in place and in good condition <br /> 4.2 MR Findings <br /> The results of soil samples collected for laboratory analysis during exploratory drilling <br /> for monitoring well UST-5 are described in Table 1 TPH-D concentrations in soil <br /> ranged from 16,000 milligrams per kilogram (mg/Kg) at 20 feet bgs to non-detect in <br /> samples at 35 feet and 62 feet bgs TPH-G ranged from 9,600 mg/Kg at 20 feet bgs to <br /> non-detect in samples at 55 and 62 feet bgs BTEX in soil at 20 feet bgs was reported to <br /> be 44 mg/Kg for benzene, 480 mg/Kg for toluene, 180 mg/Kg for ethylbenzene, and 680 <br /> mg/Kg for total xylenes BTEX was non-detect at 62 feet bgs <br /> F 169254WVQM96 RPT 5 Environmental Science&Engineering, Inc <br />
