S Monitoring wells remaining on-site,fate, <br /> There are currently three monitoring wells(MW-5,MW-6, and MW-8) and three SVE wells(VE-1 <br /> through VE-3) The three SVE wells will be properly destroyed once Shell receives a No Further <br /> Action Required letter Shell is willing to transfer ownership of the groundwater monitoring wells to <br /> another party (Chevron or the current station owner) if SJCEHD and CVRWQCB deem this <br /> appropriate Othermse,the monitoring wells will also be properly destroyed once Shell receives a No <br /> Further Action Required letter <br /> 6. Tabulated results of all groundwater elevations and depths to water, <br /> Tabulated historical depth to groundwater and groundwater elevation data are presented in <br /> Attachment C <br /> 7 Tabulated results of all sampling and analyses, <br /> Historical soil tables are presented in Attachment B and tabulated groundwater analytical data are <br /> presented in Attachment C <br /> 8. Concentration contours of contaminants found and those remaining in sod and groundwater, <br /> both on-and off-site; <br /> Iso-concentration contour maps were not completed for this site Instead, Cambria presents a <br /> discussion of the vertical and lateral extents of petroleum hydrocarbons and fuel oxygenates in soil <br /> and groundwater beneath the site Soil analytical results from investigations including, and <br /> subsequent to,the tank removal activities during January 1999 demonstrate that the residual petroleum <br /> hydrocarbons and MTBE in soil are linuted to the northwestern dispenser area TPHg and BTEX are <br /> fully delineated around this dispenser by borings SB-1, SB-2 (MW-5), and SB-6 through SB-9 Prior <br /> to the SVE test,MTBE was delineated to the southwest, south, east, and northeast of the northwestern <br /> dispenser by bonngs SB-1, SB-3, SB-4, SB-5, and SB-9 After the SVE test, a confirmation boring <br /> (VE-3)was placed in the source area,adjacent to the boring with the highest MTBE detections(SB-2) <br /> No MTBE was detected in the confirmation boring TPHg, BTEX, MTBE are delineated vertically <br /> in soil and groundwater by boring CPT-2 TPHg, BTEX, and MTBE are delineated laterally in <br /> groundwater, as they have not been detected in any of the wells (MW-5, MW-6, and MW-8) since <br /> March 2002 <br />
