Meays <br /> San Joaquin County Public Health Services <br /> Environmental Health Division <br /> 304 East Weber Avenue <br /> Stockton, California 95202 <br /> f <br /> Subject: JC Trucking Site <br /> Stockton, California i <br /> Dear Ms. Meays: <br /> In confirmation of our earlier meeting, I have attacfied information regarding the status <br /> 1 <br /> of the JC Trucking Site. As you are aware, drilling at the site occurred on January 8; we <br /> proceeded in full belief that-everything was in compliance with P'HSEHD guidelines and that <br /> you were aware of the proposed date. We regret the fact tliLt errors in communication were <br /> made which led to this confusion. <br /> Four soil borings were advanced by TEG. Each boring extended to depths of 42 to 43 { <br /> ft, which coincided with groundwater entering the boringsgro�dwater stabilized at a depth of <br /> approximately 35 ft below surface grade. Bill Welter has told me that he attempted to <br /> communicate with you several times after the drilling to discuss the drilling and sample <br /> selection. He has submitted three samples from each boring to the laboratory, which included <br /> samples from 15 ft, 26 ft, and 3.6 ft below surface grade, except-in the fourth b6rirrg-where two <br /> samples were selected from 25 Rand 31 ft below grade. A. water sample was collected from <br /> the first boring. Additional samples from all intervals are available at my office under <br /> refrigeration. The borings included one near the center of each flank location and two in the <br /> area between the tanks. Since Bili has handled the field work at 1hrs site, he has the boring <br /> logs, map, and other data at his house, where he often telec:ommutes from, while he is on <br /> vacation in the Lake Tahoe area. They are therefore unavailable to me at this time. <br /> Appropriate maps, logs, and field records will be forwarded by fax as soon as they are <br /> available. <br /> i <br /> 3560 BUSINESS DRIVE, SUITE 120 SACRAMENTO, CA 95820 (916) 737-9294 FAX (916) 737-9298 <br />
