1 Landfill an Livermore, CA after having been profiled to that facility. CONCLUSIONS ' The December investigation revealed detectable concentrations of fuel hydrocarbons in soil borings EB-5 and EB-6 . Levels ' of TPH-G ranged between 40 and 150 parts per million (ppm) at 21 and 22. 3 feet bgs in EB-5. Less than 2 .0 ppm TPH-G was present at 36 and 41 feet bgs in EB-5. TPH-D was also detected at 21 and 22. 3 feet in E13-5 (at 29 and 200 ppm, respectively) . ' EB-6 was free of detectable concentrations of TPH-G and TPH-D with the exception of 1 .1 ppm TPH-G detected at 41 feet bgs. Low levels of BTEX were detected in EB-5 at 22 . 3, 26, 31 , 36, ' 41 , and 46 feet bgs and an EB-6 at 36 and 41 feet bgs. Total lead was present in all samples, ranging from 1 . 4 to 4 .4 ppm (well below 16 ppm, the average for the Earth ' s crust) . The levels of BTEX and total lead are below those which Uriah has ' found to be typically of concern to regulatory agencies . while potentially significant ( 69-350 ppm total TPH) soil ' contamination was detected at 21 and 22.3 feet bgs in EB-5, this interval is bracketed by soil samples virtually free of detectable concentrations of TPH and BTEX ( i .e. the sample acquired from 16 feet was N.D. for all analytes and the sample from 26 feet contained only . 007 ppm ethylbenzene) . Thus, the vertical distribution of contaminants appears limited to an interval as small as 1 .3 feet (between 21 and 22 .3 feet bgs) ' and no larger than 9 feet (between 16 . 5 and 25 . 5 feet bgs) . The presence of contaminants at the referenced depths is ' consistent with adsorption of TPH onto the soil from contaminated groundwater during periods when the water table was at a lesser depth. . .such as during 1988 , when the depth to groundwater for the area was reported to be approximately 30 feet (telephone communication with DHS/EHD, February 5, 1992 ) . Analyses of grab water samples collected from the soil borings ' revealed 170-200 parts per billion (ppb) TPH-G and 82-98 ppb TPH-D in water samples from borings EB-4 and EB-5. Chromato- graphic patterns atypical of fuel hydrocarbons in water samples ' from EB-4 and EB-5 prompted further analyses of these samples using EPA Method 601 . As a result, the chlorinated compounds 1 ,2 Dichloroethane (1 , 2 DCA) and Perchloroethene ( PCE) were detected at 33-100 ppb and <0.5-11 ppb, respectively. The grab ' water sample from EB-6 was free of detectable concentrations of TPH and, although the chromatographic pattern was reported by the laboratory as consistent with the presence of Halogenated Volatile Organics (HVOs) , no HVOs were present above detection limits. Lead was detected in the water samples acquired from 4 . ■
