1 <br /> lie collected for laboratory analysis from 15 and 20 feet bgs The second soil boring (D-2) was <br /> located to the south and west of the former west dispenser and drilled at an angle of 30 degrees <br /> off-vertical The boring was angled under the former dispenser and drilled to a total vertical <br /> depth of approximately 23 feet bgs From D-2, soil samples were collected for laboratory <br />' analysis from approximately 14 and 23 feet bgs (vertical depth) All four of the soil samples were <br /> analyzed for TPH-as-gasoline and BTEX by Modified EPA Method 8020/8015 and for MTBE by <br /> EPA Method 8260 <br /> Based on the results of the soil samples collected from the angled sod boring D-2, the vertical <br />' extent of impacted soil appeared limited to shallow subsurface soil The sod sample collected at <br /> 14 feet bgs from D-2 only contained a trace concentration of MTBE (0 0054 mg/kg) The soil <br /> sample collected at 23 feet bgs from D-2 did not contain detectable concentrations of MTBE, <br />' BTEX or TPH-as-gasoline TPH-as-gasoline and BTEX were not detected in either soil sample <br /> collected from D-2 Only a trace concentration of MTBE was detected in the soil sample <br />' collected at 20 feet bgs from D-1 TPH-as-gasoline and BTEX were not detected in either of the <br /> soil samples collected from D-1 <br /> On February 12, 1998, under PHS/EHD observation, L&M Construction excavated <br /> approximately 60 cubic yards of impacted sod from the vicinity of the west dispenser island The <br /> Ile depth of the excavation ranged from approximately 7 feet near the former dispenser to <br /> approximately 12 feet beneath the former underground product distribution piping The <br /> excavated soil was stockpiled on site and remediated by passive aeration Soil sampling and <br /> Ianalysis to confirm the excavation limits were not recorded in the regulatory case file <br /> On October 1, 1998, under PHS/EHD observation, FGL Environmental re-sampled the soil <br /> stockpile Two soil samples were collected from the accumulated sod stockpile for laboratory <br /> composite and analysis The composite soil sample was analyzed for TPH-as-gasoline and <br /> IBTEX by Modified EPA Method 8020/8015 and for oxygenates by EPA Method 8260 Based on <br /> the results of the sod sample analyses, PHS/EHD allowed the soil stockpile to be disposed of <br /> Ion-site <br /> On October 1, 1998, under PHS/EHD observation, FGL Environmental also sampled the one <br /> on-site water supply well, located approximately 100 feet northwest of the former gasoline USTs <br /> (Figure 2) The groundwater sample was analyzed for TPH-as-gasoline and BTEX by Modified <br /> EPA Method 8020/8015 and for oxygenates by EPA Method 8260 None of the analytes were <br /> detected in the water sample Well construction details were not available The results of the <br /> domestic well groundwater analyses are summarized in Table 3 <br /> 5 <br />
