Cherokee Truck Stop 4 = August 25, 2011 <br /> Recommendation <br /> September 2009, Fund recommends that the San Joaquin County LOP direct the Responsible <br /> Party to assess remedial technologies that would achieve Water Quality Objectives in a timely _ <br /> manner. The Fund will review this site next year to track progress. <br /> UPDATED, September 2010, the Fund recommends that the San Joaquin County review this <br /> site for closure. <br /> UPDATED, September 2011, monitoring well MW-5 screened in the source area have <br /> consistently had elevated concentrations of 1,2 DCA in groundwater. However, after 10 years <br /> of monitoring; the groundwater plume is largely limited to the source area and is decreasing in <br /> concentrations without active remediation. Analytical data indicate that WQOs have been <br /> achieved in down gradient wells. Groundwater within the source area will likely remain above <br /> WQOs for years. The Fund recommends that the San Joaquin County LOP review this site for <br /> closure. <br /> Kirk Larson, P.G. Date Robert Trommer, C.H.G.
