I <br />' laboratory detection limits in the ground water samples analyzed <br /> i <br />' Four soil borings, MW-1, MW-2, MW-3, and B4 were advanced on 09, 10, and 16 October 2003 <br /> for the collection of soil samples and installation of three ground water monitoring wells (MW-1, <br /> MW-2, and MW-3) B4 was properly abandoned with a grout slurry to EHD specifications Pilot <br />' borings MW-1, MW-2, and.MW-3 were completed as ground water monitoring wells of the same <br /> designations using 2-inch diameter PVC casing with 0 020-inch slotted screen Installed from <br /> approximately 14 feet to 34 feet bsg The filter pack (No 2/12 Lonestar sand) was Installed from <br />' approximately 12 feet to 34 feet bsg, and a nominal 2-foot bentonite chip plug was installed above <br /> the filter pack and hydrated The wells were grouted to near the surface with portland cement, and <br /> water-tight, traffic-rated well boxes were installed over the wells <br />' A total of 13 soil samples were analyzed for TPH-g, TPH-da BTEX five fuel additives, lead <br />' scavengers,and total lead TPH-g was detected in soil samples collected from borings B4 and MW-2 <br /> at concentrations of 12 milligrams per kilogram (mg/kg) (B4-25) and 1 8 mg/kg (MW2-35) <br /> Benzene, toluene, ethylbenzene, and total xylenes were detected in soil samples collected from <br />' borings B4 and MW-2 at maximum concentrations of 0 044 mg/kg (MW2-35), 0 27 mg/kg <br /> (MW2-35), 0 15 mg/kg (B4-25), and 0 35 mg/kg (MW2-35), respectively Total lead was detected <br /> in all samples analyzed from borings MW-1 through MW-3 at concentrations ranging from 6 3 mg/kg <br />' (MW2-35)to 15 mg/kg(MW1-35), total lead was not detected above the laboratory detection level <br /> or 5 0 mg/kg m the samples analyzed from B4 No additional analytes were detected at or above <br /> laboratory reporting limits <br /> •} One grab ground water sample (B4-H20) was taken from boring B4 at an approximate depth of <br /> 53 feet bsg and was analyzed for TPH-g, TPH-d, BTEX, five fuel additives, and lead scavengers <br />' TPH-g and TPH-d were detected at concentrations of 14,000 Ag/l and 11,000 µg/1, respectively <br /> Benzene, toluene, ethylbenzene, and total xylenes were detected at concentrations of 11 pg/l, <br /> 260 µg/l, 430 µg/1 and 2,650 µg/1, respectively The lead scavenger 1,2-DCA was detected in the <br />' ground water sample at a concentration of 2 2 ug/l No additional analytes were detected at or above <br /> laboratory reporting limits <br /> I <br /> 1 <br /> I <br /> I <br /> �l <br /> IAdvanced GeoEnviron mental,Inc <br /> I <br />
