Current conditions at the site indicate that the soil contamination is continuing to <br /> degrade groundwater and that the plume is not stable. The sandy geology at the site allows <br /> contamination to move freely into groundwater and also allows removal of contamination using vapor <br /> extraction and air sparging technology. The results of the feasibility study indicate that air sparging <br /> with vapor extraction is the cost effective alternative for remediation of the site. <br /> PHS/EHD recommends that a workplan describing remediation system details be submitted to this <br /> agency by September 30, 1996. Methodology for evaluating the efficacy of the remediation system and <br /> contingencies for air channeling and iron deposition shall be included in the workplan. The vapor <br /> extraction/air sparge system will be evaluated by PHSIEHD, 6 months from startup, to insure that the <br /> system is providing cost effective remediation of the site. <br /> Once the workplan is approved by PHSIEHD, you should submit the workplan and cost estimate to the <br /> SWRCB for pre-approval to assure reimbursement of costs associated with this project. <br /> For additional information please contact Steven Sasson at (209) 468-3459. <br /> Donna Heran, RENS, Director <br /> Envionmental Health Division <br /> ven' Sa n RENS Marpreklagorio, RENS <br /> Site Mitigation Unit Supervisor <br /> SS <br /> c: Mel Jacobo, SWRCB <br /> Elizabeth Thayer, CVRWQCB <br /> William Little, Advanced GeoEnvironmental <br /> A Division of San Joaquin County Health Care Services <br />
