STATE OF CALIFORNIA GEORGE DEUKMEJIAN, Governor <br />CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD— <br />CENTRAL VALLEY REGION <br />3443 ROUTIER ROAD <br />SACRAMENTO, CA 95827-3098 <br />11 December 1989 <br />Lieutenant Colonel <br />Director, Office of <br />Defense Depot Tracy <br />Tracy, California <br />izr <br />Eddie D. Helton <br />Installation Se u,, C� 15 1989 <br />rAL <br />�'ER/V11-r/S`RViCES STH <br />PROPOSED DRINKING WATER WELL CONSTRUCTION, DEFENSE DEPOT TRACY, <br />SAN JOAQUIN COUNTY <br />Enclosed are our comments on the proposed installation of two new <br />drinking water wells. The proposed design of the wells, <br />specifically the isolation of the Upper Tulare Formation, appears <br />sufficient to ensure good quality water from these wells. The <br />location of the wells do not appear to be within or proximal to <br />known contamination areas, however, we suggest that the wells be <br />located, if at all possible, at the maximal distance from known <br />contamination areas. If this is not possible, we believe that <br />the proposed locations give a reasonable assurance that ground <br />water extractions from these wells will not significantly alter <br />contaminant plume migration patterns in the Upper Tulare <br />Formation. <br />If you would like to discuss these comments please contact John <br />Tomko at (916) 361-5661. <br />Anton K.J.
