the boring logs The FID measures the concentration of volatile organic compounds <br /> (VOC) in the atmosphere (headspace) within the sealed plastic bag This measurement <br /> is an indication of the concentration of VOC's in the soils Concentrations of VOC's <br /> encountered in the field screening process at B1 indicate approximately 15 ppm, 65 ppm, <br /> and 15 ppm at depths of 10 feet, 15 feet and 20 feet bgs, respectively A concentration <br /> of 15 ppm was observed at a depth of 15 feet bgs at boring B3. There was no FID <br /> response to headspace samples obtained at other soil sample locations Please refer to <br /> Appendix B for results of FID field screening results <br /> 3.0 LABORATORY RESULTS <br /> Soil samples were submitted to Sequoia Analytical (a state certified laboratory), located <br /> in Sacramento, California, for laboratory analyses Laboratory analyses included EPA <br /> Method 8020 for benzene, toluene, ethyl benzene, and xylenes (BTEX), EPA Method <br /> 8015 Modified for total extractable petroleum hydrocarbons (TPH) as diesel, EPA <br /> Method 8010 for halogenated volatile organics (HVO's), and DOHS/LUFT Method for <br /> organic lead Table 1 is a Summary of Laboratory Analyses Results <br /> Laboratory analysis results for BTEX was "not detected" above the method detection <br /> limit (ND) for samples B1-15', BI-25', B3-15', and B4-5' The method detection limit is <br /> 0 005 milligram per kilogram (mg/kg) for each analyte. <br /> K084023 RPT <br />
