■VL1 INC <br /> 4.5.2 Boring T-2 <br /> Results of laboratory analyses for boring T-2 are shown on Appendix II - Table 11 No <br /> VOCs were reported from any of the samples collected from boring T-2 with the <br /> exception of 1,1,1-trichloroethane at a concentration of 001 ppm from the duplicate <br /> sample collected at a depth of 20 feet <br /> Hydrocarbons as diesel were reported in the sample collected from a depth of 5 feet at <br /> a concentration of 260 ppm, the 10 foot sample at a concentration of 3,000 ppm, and the <br /> 35 foot sample at a concentration of 6 ppm Hydrocarbons as gasoline were not <br /> detected in any of the boring T-2 samples with the exception of the sample collected at <br /> ten feet at a concentration of 52 ppm Total petroleum hydrocarbons were reported at <br /> concentrations of 450 ppm and 4,500 ppm from depths of 5 to 10 feet, respectively <br /> Total petroleum hydrocarbons were not detected below a depth of 10 feet <br /> • The sample collected at a depth of 10 feet was analyzed for total manganese The <br /> i <br /> reported concentration was 400 ppm This reported manganese concentration is well <br /> within the range of naturally occurring concentrations in soils in this area (Page, 1986) <br /> 4.5 3 Boring AB-1 <br /> Results of laboratory analyses for boring AB-1 are shown on Appendix I - Table 14 No <br /> targeted chemical species were detected from samples collected from boring AB-1 The <br /> sample collected from a depth of 16 feet (four feet below the tank perimeter) was <br /> analyzed for total manganese resulting in a reported concentration of 760 ppm This <br /> reported manganese concentration is well within the range of naturally occurring <br /> concentration in soils in this area (Page, 1986) <br /> 12270010 013 Page 14 <br />
