4. Stockpiled soil remaining on-site�or off-site disposal(guarrtity). <br /> f . <br /> _ Soil excavation was not selected as a remedial alternative. Therefore, significant <br /> quantities of soil were never'excavated, stockpiled on-site, or transported off-site. <br /> II. 5. Monitoring wells remaining on-site fate. <br /> � <br /> Wells rem - <br /> remaining on site include;monitoring wells MW'1 through MW-8A/B, nested <br /> vapor extraction wells VW-1 and€VW-2, and single depth vapor extraction wells VW <br /> .3 and VW-4: Monitoring well and:vapor extraction well locations are shown on <br /> Figure 3, and well construction details are presented in Table 2. Pending site <br /> closure, these wells will be destroyed in a manner consistent with applicable San <br /> Joaquin County regulations. <br /> L 6. Tabulated results of all groundwater elevations and depths to water. <br /> U <br /> Cumulative groundwater elevation and depth to groundwater data for site monitoring <br /> wells are presented in Table 4. <br /> 7. Tabulated results of all sampling and analyses includir g defection limits for <br /> confirmation sampling and lead analyses. <br /> A summary of laboratory analytical results for soil samples collected from the UST <br /> excavation, in addition to soil samples collected from borings SB-1 through SB-4, <br /> MWA through MW-7 and VW-1 through VW-4 are presented in Table 1. In addition, <br /> 3 `f <br /> confirmation soil boring analytical;results for cone penetration test boring CPT-1A are <br /> presented in Table 5. <br /> Cumulative groundwater analytical results for site monitoring wells, vapor extraction . <br /> wells, and Irrigation Well #2.are included in Table 3. In addition, deep groundwater <br /> samples collected from cone'penetration test borings CPTH through CPT-4 are <br /> summarized in Table 6. Finally, r.onthly groundwater analytical results from batch <br /> groundwater extraction conducted on wells MW-5 and'sMW-7 between December <br /> 2003 and June 2004 are includedin Table 7. <br /> r <br />
