1 <br /> 1 Analytical Results - Groundwater <br /> The results of laboratory analyses of groundwater samples collected from monitoring wells <br /> 1 MW-1, MW-2, and MW-3, indicate that petroleum constituents and lead were not detected above <br /> 1 method detection limits in the samples collected Analytical results are shown in Table 2 A copy <br /> of the laboratory report and chains of custody are presented in Appendix IV <br /> 1 <br /> SUMMARY AND RECOMMENDATIONS <br /> 1 <br /> The findings gathered during the investigations at the site can be summarized as follows <br /> 1 <br /> 1 o The groundwater flow direction in January 1996 was towards the northwest with a hydraulic <br /> gradient of 0 002 ft/ft <br /> o TPHg and BTEX were only detected in soil on-site in a fill sample collected from boring SB-3 <br /> at 6 feet bgs <br /> 1 o TPHmo was detected in a soil sample collected from boring MW-3 at 4 feet bgs, and was not <br /> detected in the deeper soil sample from MW-3 <br /> 1 o Lead was detected in all soil samples analyzed at concentrations considered to be typical soil <br /> l' Y <br /> 1 background concentrations <br /> o Petroleum hydrocarbon constiuents and lead were not detected in groundwater samples <br /> 1 collected from monitoring wells MW-1, MW-2 and MW-3 <br /> ' In conclusion, it appears that groundwater on-site has not been impacted by petroleum <br /> 1 hydrocarbons or lead from the former USTs A small area of fill in the former gasoline UST pit <br /> contains TPHg and BTEX concentrations This is probably a result of the excavation of the <br /> gasoline USTs, and does not appear to be affecting groundwater on-site In addition, shallow soil <br /> W-1951 I"SA d1w 6 <br /> 1 <br /> SMTH <br />
