i <br /> i <br /> 6.0 CONCLUSIONS AND RECOMMENDATIONS <br /> Conclusions of the soil and ground water investigation are presented below, followed by <br /> recommendations. <br /> :i <br /> j <br /> 6.1 Conclusions <br /> Soil i <br /> * Low level TPH hydrocarbon mixtures (ranging from,2.8 to 67 mg/kg) were detected <br /> in shallow soil at each boring (at 3.5 feet bgs); but were non-detect in deeper soil (at <br /> 9.5 feet bgs). <br /> I <br /> * Toluene and xylenes were detected at low levels (2.6 and 5.3 µg/kg, respectively) in <br /> shallow soil at SB-01 (at 3.5 feet bgs); and were non-detect in deeper soil (at 9.5 feet <br /> 1 <br /> bgs). Both concentrations are well below their respective residential PRG. <br /> N <br /> * Soil staining was noted on the soil boring log for SB-02 from 3.5 to 4.0 feet bgs; the <br /> soil sample collected at this depth indicated TPH hydrocarbon mixtures at 67 mg/kg; <br /> VOCs, and SVOCs were non-detect. <br />� L <br /> Ground Water <br /> * TPH, SVOCs, benzene, ethylbenzene and xylenes were not detected in any ground <br /> F <br /> Cwater samples analyzed. <br /> I <br /> j <br /> 808-001.rprl04-29-971ulkeydaalrepom 24 IE <br /> t <br />
