4004 IcaI Teawcs 14t. �.✓ � � Site Characterization Report Page 5 j Project No. 1218.2 February 9,2006 Geologic cross section interpretations of the site's soils are presented in Figures 4 and 5. See figure 3 for cross section locations. 3.2 Analytical Results Soil samples were collected from each of the borings and submitted for Iaboratory analyses with the following results: SB-1 The soil sample collected at 12 feet bgs contained trace xylene (0,0062 mg/kg) and a low level of diesel (1.2 mg/kg). • The soil samples collected at 20 and 30 feet bgs did not contain petroleum contaminants above the laboratory reporting limits. SB-2 • The soil sample collected at 12 feet bgs contained trace'kylene (0.0068 mg/kg). • The soil sample collected at 20 feet bgs contained trace toluene (0.0056 mg/kg) and xylene (0.024 mg/kg). • The soil sample collected at 30 feet bgs did not contain"petroleum contaminants above the laboratory reporting re ortin limits. � SB-3 • The soil sample collected at 20 feet bgs contained a low level of diesel (I 10 mg/kg). • The soil sample collected at 30 feet bgs contained trace xylene (0,0051 mg/kg). • The soil sample collected at 35 feet bgs contained trace Ixylene (0.0057 mg/kg). The soil sample collected at 52 feet bgs did not contain'petroleum contaminants above the laboratory reporting limits. 5 • The water sample collected at 60 feet bgs did not contain petroleum contaminants above the laboratory reporting limits. (See Appendix B,Laboratory Reports) SB-4 ` • The soil sample collected at 12 feet bgs did not contain" etroleum contaminants above the laboratory reporting limits. The soil sample collected at 20 feet bgs contained trace';xylene (0.0070 mg/kg). • The soil sample collected at 30 feet bgs did not contain�petroleum contaminants above the laboratory reporting limits. SB-5 t • The soil sample collected at 17 feet depth contained trace toluene (0.014 mg/kg), xylene (0.044 mg/kg), and a low level of diesel (12 mg/kg). This sainple corresponds to 12 feet bgs due to the 45drill angle.
