If groundwater is encountered in the borings, a grab groundwater sample <br /> will be collected from each boring with a HydroPurich sampler and analyzed for <br /> TPHGBTEX, TPHD-extended, and chlorinated solvents. <br /> All drilling and sampling equipment will be decontaminated between borings. Following <br /> soil and groundwater sample collection, the borings will be backfilled with cement- <br /> bentonite grout. <br /> Two to four weeks after receiving analytical results,EMCON will submit a letter report to <br /> San Joaquin County Environmental Health Division presenting findings and certified <br /> analytical reports. <br /> I. <br /> If you have any questions or comments about the proposed work,please feel free to call. <br /> Sincerely, <br /> EMCON Associates j <br /> } <br /> Aoaudon'� Robert H.
