MIMI <br /> EMN <br /> An onsite geologist will visually inspect the drill cuttings <br /> and split spoon samples during the boring operations to <br /> prepare geologic logs of the soil borings. The geological <br /> .logs of the soil borings will be prepared in an attempt to <br /> identify the presence of any impermeable strata which may <br /> �.� cause lateral movement of any contamination. The soil samples <br /> 3 " <br /> will be screened for volatile organic compounds (VQC ) by using <br /> a photoionization detector (PID) . <br /> i <br /> �• Soil samples taken just above the ground water table as well <br /> as selected samples showing positive PID readings will be .sent <br /> , to a California certified laboratory for analysis for <br /> .; extractable and volatile hydrocarbons. Previous soil sampling i <br /> results for a depth of 28 feet indicate that benzene, toluene, <br /> i.m <br /> xylene, ethylene dibromide, and organic lead are below <br /> required levels in soils, and are no longer of concern in <br /> soils. Therefore, these parameters will not be analyzed in <br /> i <br /> the soil samples. <br /> The monitor wells will be developed, purged of three well { <br /> volumes, and sampled. The ground water samples will be sent <br /> -� to the lab for analysis for total petroleum hydrocarbons, <br /> benzene, toluene, xylene and lead. Any remaining drill <br /> . txr <br /> cuttings will be retained on site until lab analyses are <br /> completed. If allowed by San Joaquin APCD, the drill cuttings <br /> E � will be spread in a thin layer on the ground onsite to enhance <br /> tw <br /> volatilization and biodegradation of contaminants. If not <br /> !' allowed by San Joaquin APCD, the drill cuttings will be <br /> In disposed of in an approved disposal facility. The results of <br /> �. both soil and water analyses will be reported to the San <br /> Joaquin Local Health District and the California Water Quality <br /> Control Board (WQCB ) . <br /> 5W4 .'
