See <br /> figure 3 for cross section locations. <br /> 3.2 Analytical Results <br /> Soil samples were collected from each of the borings and submitted for laboratory analyses <br /> with,the following results: <br /> �a <br /> SB-1 <br /> • The soil sample collected at 12 feet bgs contained trace,xylene (0.0062 mg/kg) and 'a low <br /> level of diesel (1.2 mg/kg). s <br /> • The-soil samples collected at 20 and 30 feet bgs did not contain petroleum contaminants <br /> above the laboratory reporting limits. <br /> 'SB-2 <br /> • The soil sample collected.at 12 feet bgs contained trace xylene(0.0068 mg/kg). <br /> • The soil sample collected at 20 feet bgs contained trace toluene (0.0056 mg/kg) and <br /> xylene (0.024 mg/kg). ,; <br /> • The soil sample collected at 30 feet bgs did not contain petroleum contaminants above the <br /> laboratory reporting limits. <br /> SB-3 <br /> • The.soil sample collected at 20 feet bgs contained a low level'of diesel (110 mg/kg). <br /> • The soil sample collected at 30 feet bgs contained trace xylene (0.0051 mg/kg). <br /> � <br /> 9 . The soil sample collected at 35 feet bgs contained trace'xyletie(0.0057 mg/kg). <br /> • The soil sample collected at 52 feet bgs did not contain,petrol�eum contaminants above the'. laboratory reporting limits. " <br /> • The water sample collected at 60 feet bgs did not contain petroleum contaminants above <br /> the laboratory reporting limits. (See Appendix B, Laboratory Reports) <br /> t. SB-4 <br /> • The soil sample collected at 12 feet bgs did not contain petroleum contaminants above the <br /> laboratory reporting limits. <br /> • The soil sample collected at 20 feet bgs contained trace'xylene (0.0070 mg/kg). <br /> • The soil sample collected at 30 feet bgs did not contain''petroleum contaminants above the <br /> laboratory reporting limits. <br /> SB-5 <br /> • The soil sample collected at 17 feet depth contained trace.toluene (0.014 mg/kg), xylene <br /> (0.044 mg/kg), and a low level of diesel (12 mg/kg). This sample corresponds to 12 feet <br /> bgs due to the 45° drill angle. i <br />
