Hazelton Avenue <br /> Stockton, CA 95202 <br /> The San Joaquin County Environmental Health Department (EHD) has reviewed Second Quarter 2014 <br /> (Annual) Groundwater Monitoring Report April 2014 (GWR), dated July 15, 2014 prepared and submitted <br /> by Condor Earth Technologies, Inc. (Condor). <br /> Methyl tertiary-butyl ether (MTBE) and benzene concentrations in groundwater at the subject site exceed <br /> the concentrations that are considered to be low-threat as established in the Low-Threat Underground <br /> Storage Tank Case Closure Policy (LTCP). In GWR, Condor recommends that a work plan for an ozone <br /> injection pilot test be prepared. The EHD approves the preparation of the work plan, which should include <br /> technical justification for ozone injection. <br /> In GWR, Condor recommends the continuation of the following groundwater monitoring schedule: <br /> Semi-annually sample MW-1, MW-2, and MWA; annually sample MW-6; and biennially sample MW-3, <br /> MW-5, and MW-7. Condor also recommends that naphthalene be added to the analytical schedule. The <br /> EHD concurs with the proposed groundwater monitoring schedule and addition of naphthalene analysis. <br /> On November 7, 2014, an EHD representative attended a groundwater sampling event performed by <br /> Condor. As of this letter's date, the corresponding report, analytical data, and groundwater measurements <br /> for this event have not yet been submitted to the EHD and uploaded to the State of California's Geotracker <br /> website. Please upload the aforementioned items to Geotracker at your earliest convenience. <br /> If you have any questions concerning this letter, please contact Gabriel Gonzalez at (209) 468-3442, or by <br /> email at gagonzalez@sjcehd.com. <br /> Gabriel Gonzalez, REHS Nuel C.
