ME <br /> 1 <br /> KLEINFELDER <br /> I <br /> 1 SOIL PILE ASSESSMENT <br /> Soil excavated during the tank removal at Food and Liquor Store 37 in <br /> Tracy, was stored onsite in approximately a rectangular pattern and <br /> characterized by a portable organic vapor detector on April 3, 1488 (see <br /> . Plate 3). A Photovac TIP photoionization detector (PID) utilizing a 10.6 <br /> eV photoionization lamp was used to measure total ionizable compounds in <br /> parts per million by volume (ppmv) relative to a 100 part per million <br /> isobutylene calibration standard. f <br /> Ten '.survey points were screened with the PID to <br /> provide a qualitative <br /> r assessment . of contaminants. Soil samples were collected in brass tubes � <br /> j <br /> 1`.1from eight of ten survey points. To provide a quantitative assessment of i <br /> T contamination, sax of these soil 'samples were submitted under <br /> (.,. <br /> chain-of-custody to Chemwest Analytical Laboratories, Inc. The six <br /> ' samples were composited' by the laboratory into three samples and analyzed <br /> r.: <br /> y�y for total petroleum hydrocarbons (TPH) extractable by CC--FID and benzene, <br /> - <br /> da. toluene, ethylbenzene, and xylene (BTRXX) by EPA Method 8020.` Table l <br /> }: ti lists the locations, PID readings, and analytical results for the ten <br /> Laboratory - <br /> y . oints.P aboratory data sheets and chain-of-custody a{e enclosed <br /> in Appendix A. <br /> i <br /> 1 <br /> t �s <br /> 102-88-636 1 <br /> bw <br /> � i <br />
