Parsons Engineering Science, Inc <br /> Groundwater Elevations <br /> The groundwater elevations for the 1996 third quarter groundwater monitoring event are <br /> shown in Table 1 and Figure 3 Groundwater elevation data indicate that groundwater flows <br /> to the west-southwest with a hydraulic gradient of 0 03 ft./ft No free product or hydrocarbon <br /> sheen was observed in any of the four wells (MW-I through MW-4) <br /> ANALYTICAL RESULTS <br /> Introduction <br /> Soil samples collected at SB-9 were analyzed for TPH-D by modified EPA Method 8015 <br /> and BTEX by EPA Method 8020 Groundwater samples collected from MW-4 were <br /> analyzed for TPH-D by the modified EPA Method 8015 and BTEX by EPA Method 8020 <br /> All analyses were performed at a laboratory certified by the California Environmental <br /> Protection Agency (Cal/EPA) Environmental Laboratory Accreditation Program (FLAP) <br /> Table 2 contains analytical results for the soil samples Analytical results for the <br /> groundwater samples collected are presented in Table 3 Chain-of-custody records and <br /> certified analytical laboratory reports for soil samples collected are contained in Appendix E <br /> Chain-of-custody records and certified analytical laboratory reports for groundwater samples <br /> collected are contained in Appendix F <br /> Soil Sample Analvtical Results <br /> T <br /> Total Petroleum Hydrocarbons as Diesel <br /> TPH-D was not detected in any of the soil samples (Table 2) <br /> Aromatic Hydrocarbons <br /> BTEX compounds were not detected in any of the soil samples (Table 2) <br /> Groundwater Sample_Analvtical Results <br /> Total Petroleum Hydrocarbons as Diesel <br /> TPH-D was not detected in any of the groundwater samples (Figure 4 and Table 3) <br /> PARESSYROI VOLIRIWP\72760780969127607RO3WW6 7 <br />
