EEEr <br /> f <br /> Problem Assessment Report December 5, 1989 <br /> USA Petroleum Station No. 65, Lodi, 0.1ifornia AGS 87050-3 <br /> The groundu <br /> water flow directio , was evaluated to be to the sotheast at the time of <br /> measurement. <br /> ff <br /> i <br /> Laboratory analyses are summarized on Table 2. The field procedures and laboratory ' <br /> results of soil and water samples and gradient map were presented in Applied GeoSystems <br /> Report 87050'2 (Qctobe 13, 19H7). Copies of these boc ing logs and laboratory analyses <br /> for soil and water samples are in Appendix B. The till. Bogy of the Barings is discussed <br /> under Stratigraphy in this Problem Assessment Report. <br /> Soil and grnutnd-water samples collected were sent to the l3.awn and Caldwell analytical 3 <br /> � l <br /> laboratory in Emeryville, California, (Hazardous Waste Testing Laboratory No. 104). <br /> t Analyses for total fuel hydrocarbons(TFH), total volatile hydrocarbons (TVH), and BTEX <br /> constituents were conducted on the soil and water samples. Ethylene dibromide, and <br /> tetraethyl Iead analyses were also performed on soil samples from boring B-1 and water . <br /> samples from well MW-1. <br /> Chemical analyses of soil samples.collected from water wells h.lW-1 through MW-3 indicate <br /> TFH, TVH, and BTEX concentrations were below the detection limits for the tests used <br /> in the soil samples. Chemical analyses of the soil sample from boring 13-1 and the water <br /> ---sample-collected from well-IMV-1-indicate-.ethylene-dibrcrmide,_and tetraethyl lead were r <br /> also below the detection levels for the tests used. <br /> E <br /> i 1 <br /> j. <br /> i <br /> , <br /> t <br />
