Den's Auto Repair --4- March 3, 2011 <br /> Claim No. 10841 <br /> remediation that will achieve Water Quality Objectives in a timely manner. The <br /> Fund will review this site next year to track progress. <br /> UPDATED, April 2009, the San Joaquin County LOP approved an ozone <br /> injection pilot study. The Fund concurs with this action and will review this site <br /> next year to track progress. <br /> UPDATED, April 2010, by letter on 15 April 2010, the San Joaquin County LOP <br /> directed the Responsible Party conduct ozone injection bench scale study. The <br /> Fund concurs and will review this site next year to track progress. <br /> UPDATED, March 2011, monitoring wells (MW-2a and MW-2b) screened in the <br /> source area have consistently had elevated concentrations of residual <br /> hydrocarbons in groundwater. However, after 13 years of monitoring, the <br /> groundwater plume is largely limited to the source area. Analytical data indicate <br /> that WQOs have been achieved in down gradient of the source area. <br /> Groundwater within the source area will likely remain above WQOs for decades <br /> to hundreds of years. The Fund recommends that the San Joaquin County LOP <br /> review this site for closure. <br /> k Larson, P.G. Date Robert Trommer, C.H.G.
