` SECTION 5 <br /> CONCLUSIONS AND RECOMMENDATIONS <br />' Safeway and ERM-West believe that the following conclusions can be <br /> drawn regarding the Meat Packing Facility in Stockton <br /> • Whale soil containing low levels of TPH-diesel as present on site <br />' and under Navy Drive, groundwater has not been seriously <br /> impacted <br />' • Biotreatment of soils from drill cuttings is ongoing on the <br /> property <br />' • Drummed purge water is stored on site and Safeway is requesting <br /> that the County allow for disposal on site <br />' The following recommendations are made regarding the site: <br /> • Quarterly groundwater monitoring will continue Potentiometric <br /> maps will be prepared along with the presentation of each <br /> quarter's analytical results Parameters such as pH, <br /> conductivity, and temperature will also be included TPH-diesel <br />' <br /> will continue to be analyzed at all three monitoring wells Total <br /> coliform will continue to be analyzed at monitoring well MW-6. <br /> Based on results, we believe that BTEX analyses can be <br /> discontinued at all three monitoring wells <br />' • Unless changes in groundwater movement occur, an upgradient <br /> well is not necessary at this time. <br />' • Further delineation around the UST fuel lines would not be likely <br /> to substantially advance the current understanding of subsurface <br /> Iconditions <br /> • Based on the lack of significant contanunation, no additional <br /> investigation or remediation is planned for the near fixture <br /> I <br /> I 5-1 <br />
