EI Dorado Street <br /> Stockton , CA 95206 <br /> Subject: QUICK & SAVE <br /> 1901 SOUTH ELDORADO <br /> STOCKTON CA 95206 <br /> The San Joaquin County Environmental Health Department ( EHD) has reviewed <br /> Extraction Well EW- 1 Development dated February 12 , 2007, prepared by Advanced <br /> Geo Environmental, Inc. (AGE) and has the following comments . <br /> In accordance with EHD 's directive letter dated December 8, 2006 , AGE redeveloped <br /> EW-1 on December 20, 2006. During this redevelopment, the maximum sustainable <br /> purge rate was 10 gallons/hour, or less than 0. 17 gallons/minute. AGE concluded that <br /> EW-1 appears to be adequately developed and that the Ground Water Pump Test and <br /> Soil Vapor Extraction Pilot Test Report dated March 20, 2006 remains valid . AGE <br /> concludes that groundwater extraction (GWE) at the site does not appear to be feasible <br /> and that site conditions appear to be suitable for dual phase extraction (DPE). <br /> EHD concurs that interim remediation should be implemented due to MTBE levels in <br /> groundwater exceeding 10, 000 pg/I . Submit a work plan to conduct a pilot DPE test by <br /> July 7, 2008 . <br /> If you have any questions, please contact Frank Girardi at (209) 953-7868 . <br /> Frank Girardi, REHS Nuel C.
