i <br /> Fayette Manufacturing C -4 - ,-, October 25;201 T <br /> f <br /> UPDATED, May 201,0',--active remediation is overdue for this site. Thea=und recommends that <br /> the San Joaquin County LOP direct the;Responsible Party to begin active remediation without i <br /> delay. The Fund will review this site next year to track progress. <br /> UPDATED, November 2011, near source area monitoring well MW-1 and down gradient well j <br /> MW-3 have historically had elevated concentrations of residual hydrocarbons in groundwater. <br /> However; after 16 years of monitoring, the groundwater plume is largely limited to the source <br /> area and shrinking is size and concentr`ati6h. 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. <br /> The affected shallow groundwater is not used as a source of water supply nor is it likely to be <br /> used as.a source of:water supply in the foreseeable future. Water users.m the vicinity of the site <br /> rely on a public water supply. Based on facts in the record and hydrologic and geologic <br /> conditions at the site, the limited residual petroleum hydrocarbons that remain in soil and <br /> groundwater pose a low risk to human health, safety and the environment. The Fund <br /> recommends that the San Joaquin County LOP review this site for closure. <br /> 11/q Azo <br /> Kirk Larson P.G. pato Robert Trommer, C.H.G.
