(Pacific),to describe the findings of their soil investigation that was performed <br /> at the subject site during September, 1995. <br /> The scope of Pacific's investigation involved the drilling and sampling of five soil borings in the vicinity <br /> of the former pump islands and upgradient of monitoring well MW-2. The soil sampling protocol was <br /> designed to investigate areas beneath the former product piping that were not previously investigated and <br /> to investigate potential sources of groundwater contamination in soils upgradient from well MW-2. <br /> The source of groundwater contamination at well MW-2 was not identified by Pacific's investigation. <br /> There were detections of weathered gasoline in shallow soil at the location of boring B-3. The vertical <br /> extent of this contamination was not defined due to the presence of metallic objects below surface. Since <br /> boring B-3 was located in the vicinity of former product piping, it is suspected that the metallic objects <br /> encountered are product piping left in place from the 1986 service station reconstruction work. <br /> The results obtained from Pacific's investigation do not appreciably change the conceptual site model <br /> described by Pacific in their Corrective Action Plan dated,April 4, 1995. As such, Chevron will continue <br /> to support and recommend the acceptance of Pacific's intrinsic bioremediation proposal. <br /> If you have any questions or comments,I can be reached at(510)842-8695. <br /> Sincerely, <br /> Brett L.
