Box 2009 <br /> Stockton, California 95201 <br /> SUBJECT: 3535 E. CHEROKEE ROAD, STOCKTON, CALIFORNIA <br /> SITE CODE 1800 <br /> Dear Mr. Infurna, <br /> Environmental Science & Engineering, Inc. (ESE) on behalf of Cecchini, Cecchini, and <br /> Giovannoni notify you of quarterly monitoring at the subject site on July 28, 1993 <br /> commencing at 9 a.m.. <br /> ESE will measure water levels in well UST-1 at the fueling island and wells SI-1, SI-2, and <br /> SI-3. Well UST-1 will be purged and sampled in accordance with standard procedures. <br /> Analysis of ground water from UST-1 will include Total Petroleum Hydrocarbons (TPH) <br /> as gasoline and diesel and Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) by EPA <br /> Methods 8015 modified and 8020 respectively. <br /> Mr. Robert Cecchini has sampled the two domestic water wells at the site and has arranged <br /> for analysis of those samples in accordance with your letter of June 1, 1993 and <br /> requirements of Mr. Ray Borges of San Joaquin County Public Health. <br /> Sampling and analysis of wells SI-1, SI-2, and SI-3 will be deferred pending your review of <br /> the enclosed document. These wells surround the former surface impoundment and have <br /> been sampled twice in the past. The former surface impoundment project is under the <br /> jurisdiction of the Central Valley Regional Water Quality Control Board and no monitoring <br /> of these wells has been required since the initial sampling (enclosed documents). ESE will <br /> request that the RWQCB coordinate their requirements with yours in order that they are <br /> in agreement. <br /> 4090 Nelson Avenue,Suite J Concord,CA 94520 Phone(510)685-4053 Fax(510)685-5323 <br />
