Eleventh Street <br /> Tracy, CA <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS/EHD) has reviewed <br /> the "Quarterly Report" dated October 1993, prepared by Geological Audit Services, Inc. for the above <br /> referenced site. <br /> The report describes the re-excavation of the former underground storage tank (UST) area, soil <br /> sampling of the excavation and resultant stockpiled soil, and the installation of monitoring well 4. <br /> Contaminated soil remains in place north, east and west of the excavated area and extends off-site. <br /> Quarterly monitoring of the existing monitoring wells should continue to determine what affect the <br /> removal of the contaminated soil from the former UST area has had in remediating the site <br /> contamination. Further remediation of the soil and groundwater contamination should be based on <br /> this information. Sampling of the monitoring wells should be scheduled as soon as possible. <br /> The tables of the soil and groundwater sample results contained in this report do not reflect that some <br /> samples were diluted for analysis. Therefore,the contamination levels reported do not represent what <br /> actually exists at the site. In future reports, please note when results are from a diluted sample and <br /> include the dilution factor for those results. <br /> The piping from the former underground storage tanks to the dispensers remains in place. This piping <br /> must be removed and the soil beneath the piping sampled to confirm there is no contamination in the <br /> dispenser island area. Please submit a piping removal plan to PHS/EHD by May 15, 1994. <br /> If you have any questions contact Margaret Lagorio, Senior REHS, at (209) 468-3449. <br /> Ernest M.
