EI Dorado Street <br /> Stockton, CA 95206 <br /> The San Joaquin County Environmental Health Department (EHD) has received and reviewed <br /> Quarterly Status Update Report-2 d Quarter 2012, dated July 11, 2012, and the ground water <br /> sample results for sampling that occurred on July 12, 2012, both submitted on your behalf by your <br /> consultant Stratus Inc. and has the following comments. <br /> Ground water contamination in the on-site source area remains extremely high and must be <br /> remediated. A soil and ground water remediation system has been installed at the site. The <br /> current on-site remediation system is not operating as designed. Currently soil vapor extraction <br /> (SVE) is operating, but no ground water extraction is occurring. The SVE is not removing an <br /> appreciable contaminant mass (< 1 lbs/per day). The existing ground water extraction wells are <br /> not being utilized as designed, due to project budget funding problems. <br /> If ground water extraction will not implemented, other ground water cleanup technologies need to <br /> be evaluated in order to enhance ground water cleanup and achieve ground water objectives in a <br /> more timely manor., One consideration would be to utilize the existing ground water extraction or <br /> existing vapor extraction wells for in-situ air sparing in conjunction with the on-going SVE. <br /> Please submit a ground water remediation alternative technology evaluation and work plan to the <br /> EHD by November 1, 2012. <br /> If you have any questions please contact Harlin Knoll at (209) 468-3442, or by email at <br /> hknollasicehd.com. <br /> Sincerely, <br /> Harlin Knoll, REHS Nuel C.
