Weber Ave., Third Floor • E O. Box 388 • Stockton, CA 95201.0388 <br /> 209/468-3420 <br /> MAILED APR 111996 <br /> GERALD THIEMANN <br /> 327 BLOSSOM DRIVE <br /> RIPON CA 95366 <br /> Re: Thiemann's Service Site Code: 1479 <br /> 106 Second Street <br /> Ripon CA 95366 <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS/EHD) has <br /> completed review of the "First Quarter 1996 Groundwater Monitoring Report" dated April 4, 1996 <br /> and prepared by Smith Environmental. PHS/EHD has the following comments for your <br /> consideration. <br /> The report included the analytical results from the January 12, 1996 groundwater sampling event. <br /> Significant groundwater contamination continues to be evidenced in samples collected from <br /> monitoring wells, MW3 and MW6. PHS/EHD requested in correspondence dated December 13, <br /> 1999 that a work plan be submitted to continue the groundwater investigation and to complete any <br /> feasibility studies necessary for the preparation of a corrective action plan. Please submit by May <br /> 5, 1996 the requested work plan. <br /> Groundwater samples which are collected should now include analysis for methyl tertiary butyl <br /> ether (MTBE) which is used as a fuel oxygenation compound. MTBE can be detected utilizing EPA <br /> methods 5030/8015/8020 with confirmation analysis utilizing EPA method 8260 (GC/MS). <br /> Please note that in the future, summary tables of analytical results must include the reporting limit <br /> of each sample rather than the designation of "ND". Also, PHS/EHD strongly suggests that the <br /> depth to water information be included on the same summary table as the analytical results, so that <br /> changes in groundwater depth and analytical results may be quickly noted. <br /> During the last field inspection on April 2, 1996, PHS/EHD noted the traffic boxes of MW2 and <br /> MW6 require immediate repair. Also, a number of drums containing soil and waste water are being <br /> stored on site that require disposal. Please appropriately dispose of these drums and submit a <br /> waste disposal summary. If you have any questions, please contact me at (209) 468-0337. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> Mary Meays, Senio EHS Margaret agorio, REHS <br /> Site Mitigation Unit Lead Senior <br /> MM\106SEC <br /> cc: Elizabeth Thayer, CVRWQCB <br /> cc: Jeanne Homsey, Smith Environmental <br /> A Division of San Joaquin Countv Health Care Services <br />
