S 1 � RlA 3. Figures depicting lithology (cross section), treatment system diagrams; Geologic cross sections are included in Appendix B. A GWE system was installed at the site in March 2000 and operated until July 2001. System design diagrams are included in Appendix D. 4. Stockpiled soil remaining on-site or off-site disposal(quantity); There is no stockpiled soil remaining onsite. S. Monitoring wells remaining on-site,fate; All site monitoring wells (MW-1 through MW-3, and MW4AIB through MW-6A/B) and extraction wells (EW-1 and EW-2) will be properly destroyed once Shell receives a No Further Action Required letter. 6. Tabulated results of all groundwater elevations and depths to water; . Tabulated historical depth to groundwater and groundwater elevation data are presented in Appendix A. 7. Tabulated results of all sampling and analyses; Tabulated historical soil data is presented in Table 1, tabulated grab groundwater data is presented in Table 3, and tabulated groundwater monitoring analytical data is presented in Appendix A. 8. Concentration contours of contaminants found and those remaining in soil and groundwater, both on-and off-site; TPHg and benzene have only been detected in three soil samples collected at the site (S-2, X-1, and X-2). All other soil samples collected have not contained any TPHg or benzene, including those collected from subsequently installed boring CPT-1, located immediately adjacent to the referenced samples. MTBE was detected in tank and piping replacement soil samples S-2, S-5, S-8, and T-3 East, collected in 1996, and in soil samples collected from boring CPT-1 and wells MW-1 and FW-1 I located in the immediate vicinity of the Southern dispenser island. No other soil samples collected at the site have contained any MTBE, including samples collected from . subsequently installed well MW-4A, located adjacent to CPT-1 and EW-1.
