O. Box 1210 Lodi, CA 95241 'vl' <br /> DEC 1 2 1994 <br /> Subject: Revised Monitoring and Reporting Program No. 93-701ENV(RONMENTAL HEALTH <br /> 16 South Cherokee Lane, Lodi, San Joaquin County PERMIT/SERVICES <br /> Dear Mr. Gillespie: <br /> We have received and reviewed the latest correspondence from Ms. Elizabeth Thayer at the <br /> Central Valley Regional Water Quality Control Board (CVRWQCB). The letter is dated <br /> November 22, 1994 and discussed changes to the Revised Monitoring and Reporting <br /> Program (RMRP) at 16 South Cherokee Lane in Lodi. <br /> The RMRP now includes most of the modifications suggested by GeoAudit in a letter dated <br /> October 31, 1994. We find the new RMRP to be satisfactory and do not recommend any <br /> changes at this time. While some of the data may prove to be ambiguous, the parameters <br /> measured should provide sufficient data to evaluate the progress of the bioremediation. We <br /> will be preparing a new monitoring schedule acceptable to the RMRP. <br /> As you are aware,we have completed the initial drilling to monitor bioremediation progress <br /> in the soil. We drilled a total of four soil borings on November 15 and 16, 1994. A total <br /> of 14 soil samples were analyzed by a state-certified laboratory for TPH as gasoline and <br /> BTE&X. Note: The fourth boring was placed outside the investigated soil plume. Field <br /> observations did not indicate that hydrocarbons were encountered; therefore,no soil samples <br /> from this boring were analyzed for TPH or BTE&X. <br /> Selected soil samples from each boring were also analyzed for nitrates, nitrites, phosphates, <br /> pH, bacterial composition and bacterial numbers. Analytical results of the soil samples <br /> (TPH and BTE&X) are attached. The initial results are very encouraging. A complete <br /> discussion of all soil sample analyses will be discussed in the December 1994 Quarterly <br /> Report ( to be completed by January 20, 1995). <br /> 1 <br /> Full Spectrum Environmental Services• Hydrogeology <br />
