C-SHADSOFS91.1/1.40 <br /> 12/12/91 <br /> boring just downgradient (northwest) from the slab. All soil samples were found <br /> to be free of TCE. Possible paint and solvent contamination of soil adjacent to <br /> Bldg. S-119 was investigated by collecting two surficial soil samples from depths <br /> of 0 to 0.5 ft in the immediate area of the building. Sample S3-Sl was collected <br /> approximately 15 ft west of the building; Sample S3-S2 was collected near a <br /> drainage grate located approximately 15 ft south of the building (Fig. 1.5-1). In <br /> addition, a sediment sample (S3-SED1), a water sample (S3-SWI), and a <br /> duplicate of the water sample were collected from the sump. The sediment on <br /> ithe bottom of the 4- to 5-ft deep sump consisted mostly of sand and gravel; some <br /> pipes and other obstacles also were encountered on the bottom. Sediment <br /> thicknesses varied from approximately 0 to 0.5 ft, and the water depth was <br /> approximately 1 ft. Soil, sediment, and water samples were analyzed for metals <br /> and VOCs. No VOC contamination above detection limits was observed at this <br /> J <br /> site. Elevated lead concentrations were detected in all three samples, with the <br /> sump sample the highest at 4,110 µg/g. Chromium and zinc concentrations were <br /> also high, ranging from 724 to 1,200 µg/g for chromium and 1,190 to <br /> 1,890 µg/g for zinc. <br /> Additional field testing was performed in 1991 to delineate the extent of lead <br /> contamination at Bldg. 119. The approach to the field testing, methods used; <br /> and conclusions are presented in a supplemental report to the RI (not published <br /> as of yet). The results of the study indicated the highest levels of lead <br /> contamination were found in the surface soil samples collected south, southwest, <br /> and immediately west of former Bldg. S-119. The highest lead concentration <br /> reported was 5,115 ppm. None of the split-spoon samples collected at depths <br /> between 0.5 and 4.0 ft-bls in areas with high surface soil contamination <br /> contained any measurable concentrations of lead. Also, the two samples <br /> collected at one location indicated that the contamination (4,493 ppm) was in <br /> t 1-84 <br />
