' The point of compliance for the contingency plan is downgradient well, MW-413. The <br /> contingency plan will be initiated in the event adverse effects are occurring. The contingency <br /> plan calls for removal of dissolved contaminants using a conventional pump and treat strategy. <br /> ' The pilot test (Haley & Aldrich, 2003) demonstrated that concentrations declined after pumping. <br /> To implement the contingency plan, approximately two new extraction wells — screened within <br /> the intermediate aquifer — would be installed downgradient of the three ZVI injection areas. <br /> ' Recovered water would be treated using granulated activated carbon and/or air stripping and <br /> treated water would be discharged under an NPDES permit or re-injected. If difficulties or <br /> ' delays arise in obtaining an NPDES permit, an alternative strategy would be to obtain a <br /> temporary discharge permit from the City of Stockton to allow transport of treated groundwater <br /> to the Regional Wastewater Control Facility. <br /> t <br /> R:\CONTGRAN\CC14Cargi11\French Camp\Waste Discharge Apphufion\supp info 6-29-04.doc <br /> 13 <br />
