. results are summarized in Table 1. Laboratory data sheets -w and chain-of--custody documentation are included in Appendix I. Soil boring MW-1 was converted to a grounawater monitoring well. On January 30, 1990, the well was monitored and developed in accordance with WaterWork's Well Monitoring and Development Protocols (Appendix III) . A water sample was "rt collected the same day in accordance with WaterWork' s Groundwater Sampling Protocol (Appendix III ) . The sample was analyzed by B.C. Laboratories for BTX and TPH as diesel „�. by EPA 8020 and DOHS methods, respectively. Analytical results are summarized in Table 2.

J. Heinz Inc. ` 757 E. 11th Street Tracy, CA 95376 Tank Owner and Contact Person BJJ Company Inc.. Mr. Bill Newman P.O. Box 3001 Stockton, CA 95213 ' 2.2 Map showing site location relative to nearby landmarks: The site location is shown on Figure 1. 2.3 Map showing general site features: M The site plan is presented in Figure 3. 2.4 Estimates of liquid quantity and composition leaked: No estimate of the liquid quantity leaked can be made with M- existing information. The constituents detected in the i initial soil samples appear to be derived from diesel. 2.5 Topography, geology, surface water, depth to groundwater: The site is situated on level terrain underlain by flood basin deposits of Pleistocene and Holocene age that are composed of sediments similar to and probably conformable on underlying deposits of alluvium and Tulare formation. The flood-basin deposits are light-to dark brown and grey clay, -- silt sand and organic materials with locally high t 2
