Hunter Street <br /> Stockton, California <br /> Primary Agency: Jeff Wong, San Joaquin County Environmental Health Department (SJCEHD) <br /> Copy to: James Barton, California Regional Water Quality Control Board, Central Valley <br /> Region (CRWQCB) <br /> This-is a report of the results of the first quarter 2004 groundwater monitoring event conducted January <br /> 30, 2004 at the above-referenced site. Figures indicating the site location, groundwater elevation contours, <br /> groundwater elevation fluctuations (hydrograph), benzene iso-concentration contours, MTBE iso- <br /> concentration contours, and historical MTBE concentrations in MW-3 are attached to this report <br /> (Attachment A, Figures 1, 2, 3, 4, 5, and 6, respectively). Site background information, historical <br /> groundwater monitoring data, field forms, and laboratory analytical results are provided in Attachment B, <br /> C, D, and E, respectively. This report has been submitted to the SJCEHD and the CRWQCB as indicated <br /> above. <br /> In a letter dated February 4, 2003, Mr. Jeff Wong of the SJCEHD approved Condor's proposal to reduce <br /> quarterly sampling of MW-5, MW-6, MW-7, and MW-10 to an annual basis, and the destruction of MW- <br /> 8 to accommodate site development. It is anticipated that installation of a new monitor well in the vicinity <br /> of MW-8 and an additional down-gradient well will be conducted following development of the property. <br /> Wells MW-5, MW-6, MW-7, and MW-10 are currently monitored by Condor during third quarter <br /> monitoring events and were not sampled during the January 2004 event. A summary of the results of the <br /> first quarter 2004 groundwater monitoring is provided in Table l on the following page. <br /> CONDOR <br />
