Tri-Valley, Growers November 9, 1987 <br /> Project No. 1582G page 5-g <br /> -- information, it is our opinion that the site hydrogeologic conditic is range <br /> from semi-confined to unconfined. Static water elevations were measured <br /> on September 9, 1987 with stabilized groundwater level. measured at 10 to <br /> 11 feet. A groundwater elevation countour map is presented in Figure 6. The <br /> groundwater flow direction is toward the northeast with a relatively flat <br /> gradient. <br /> T" 5.7 LBEMICAL ANALYSIS <br /> A total of nine soil samples from the three borings were analyzed for total <br /> volatile hydrocarbons (TVH), benzene, toluene and xylenes (BTX), total <br /> hydrocarbons as diesel and total lead using EPA methods 5020, 8015, 8020 <br /> and 3550. Sail sample analysis results are shown in cross sections A-A' and <br /> B-B' and are presented in Table 3 in parts-per-million (ppm). Four <br /> w groundwater samples were analyzed for TVH BTX, total hydrocarbons as <br /> diesel and total lead. The results of the laboratory analysis are presented in <br /> .�. Table 4 with the results in parts-per-billion (ppb). <br /> 'F <br />
