Box 2009 <br /> Stockton CA 95201 <br /> CHEVRON SERVICE STATION,' 2905 BENJAMIN HOLT DRIVE, STOCKTON, SITE <br /> INVESTIGATION REPORT <br /> We have reviewed the investigation report for this site, dated 13 April 1989, <br /> prepared by Western Geologic Resources, .Inc. The investigation included <br /> installation and sampling of five ground water monitoring wells. Hydrocarbon <br /> contamination was detected in soil and ground water with the most significant <br /> levels of contamination occurring in the southern part of the site. Chevron <br /> proposes-to,c-ondduct-qu-arterl,yry-moni tori-ng-and--conti nued, invest:i gat:i on-, of-thi s. <br /> site. - <br /> At this `'time it is not possible to determine whether the contaminants have <br /> migrated from the site. Additional investigation .will be necessary prior to <br /> developing a remedial action plan. <br /> Chevron should coordinate their future work at the site with activities <br /> conducted by Arco for their service station located on the south side of <br /> Benjamin Holt Drive. To be able to compare the data from the two sites, it is <br /> important that all the wells be sampled and analyzed in a uniform manner. <br /> Coordinating the ground water sampling program for these, two sites will <br /> provide the information necessary .to gain a better understanding of the <br /> distribution of contaminants. <br /> If you should have any questions, please call me at (916) 361-5731. <br /> THOMAS D.
