EI Dorado Street <br /> Stockton , CA 95206 <br /> Subject: QUICK & SAVE <br /> 1901 SOUTH EL DORADO <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 83 20063 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 Ngll. 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 /> �✓ ~ " 00 0 <br /> .e <br /> Frank Girardi, REHS Nuel C .
