(Delta), as authorized by Ultramar Inc., destroyed a ground <br /> water monitoring well MW-20 at the above referenced site on October 10, 1994. Monitoring well <br /> MW-20 was located in an area where a new station building is to be constructed. The work was <br /> approved by the San Joaquin County Environmental Health Department under Well Permit <br /> No. 004389. The location of the site is shown in Figure 1 and the previous location of monitoring <br /> • well MW-20 is shown in Figure 2. <br /> Measurements of the total depth and depth to ground water of monitoring well MW-20 were taken <br /> on October 10, 1994, with values of 68.4 feet and 56.15 feet, respectively. The well was destroyed <br /> by pumping grout from the bottom up through a tremie pipe into the 4-inch casing. The well was <br /> grouted to within 1.5 feet of the ground surface. <br /> The calculated volume of the well was approximately 0.25 cubic yards. The actual volume of grout <br /> used was approximately 0.33 cubic yards, indicating that the well and void spaces in the adjacent <br /> formation were adequately sealed. <br /> We recommend that you forward copies of this report to: <br /> Mr. Harlin Knoll Mr. James Maughan <br /> Environmental-Health Division California Regional Water Quality <br /> Public Health Services Control Board, Central Valley Region <br /> San Joaquin County 3443 Routier Road <br /> '1601 East Hazelton Avenue Sacramento, California 95827 <br /> Stockton, California, 95201 <br /> If you have any questions regarding this letter report, please call me at (916) 638-2085. <br /> Sincerely, <br /> DELTA ENVIRONMENTAL CONSULTANTS, INC. <br /> Richard E.
