Box 2009 <br /> Stockton CA 95201 <br /> CITY OF STOCKTON, POLICE FACILITY, 22 EAST MARKET STREET, STOCKTON <br /> PROBLEM ASSESSMENT REPORT <br /> We have reviewed the 15 January 1990 Problem Assessment Report prepared <br /> for this site by WaterWork. The investigation -included installation and <br /> sampling of one ground water monitoring well in the vicinity of a leaking <br /> underground fuel pipeline on-site. <br /> Although no petroleum hydrocarbons were- detected in a sample from the <br /> monitoring well , the results cannot be considered conclusive because the <br /> maximum allowable laboratory holding time was exceeded . for the sample. <br /> In addition, the gradient of ground water flow at the' site may be <br /> influenced by extraction of ground water from a production well located <br /> within the building adjacent to the -release area <br /> At a minimum, the monitoring well and Ahe production ,well within the <br /> building should be sampled to establish current water quality conditions. <br /> If pollutants are detected, it may be necessary to 'conduct a more detailed <br /> investigation to determine the gradient and the extent of impacts to water <br /> quality. <br /> If you have any questions, please call"me at (916) 361-5731 . <br /> THOMAS D.
