The highest PID value was observed in boring B6 at <br /> 55 feet bsg. <br /> In all the borings, first ground waterwas encountered between approximately 20 to 25 feet <br /> bsg. Boring logs are provided in Appendix A. Boring logs for B6 through B8 were uploaded <br /> to the State Water Board GeoTracker site; confirmation numbers are 1254989564, <br /> 4782254815, 2278195977, respectively. <br /> 3.2. HYDROCARBON-IMPACTED SOIL <br /> A total of 15 soil samples from the five soil borings and were analyzed for the constituents <br /> listed in Section 2.2. The following target analytes were detected: <br /> • TPH-g and TPH-d were detected in three soil samples analyzed from boring B6 with <br /> maximum concentration of 190 milligrams per kilogram (mg/kg; 136-35 TPH-d); <br /> lesser concentrations were detected in samples 66-55 and 66-60 at 2.0 mg/kg and <br /> 1.6 mg/kg, respectively. TPH-d were not detected in the remaining soil samples <br /> analyzed from borings. <br /> • Total xylenes was detected in samples 66-55 and 66-60 at concentrations of <br /> 0.029 mg/kg and 0.022 mg/kg total xylenes, respectively. <br /> • 1,2 -DCA was not detected in soil samples analyzed from borings. <br /> • VOCs were detected in the soil samples from boring B6 at low concentrations. <br /> • No other target analytes were detected at or above laboratory detection limits in any <br /> of the soil samples analyzed from borings B7 and B8. <br /> Analytical results of soil samples are summarized on Table 1. Laboratory reports (CTEL <br /> Project No. CT214-1202005 and 1202046), quality assurance/quality control (QA/QC) <br /> reports, and chain-of-custody forms are included in Appendix B. Laboratory electronic <br /> deliverable format (EDF) files were QA/QC checked and uploaded to the State Water <br /> Board GeoTracker site; confirmation numbers are (4797057390 and 7486098527) <br /> 3.3. HYDROCARBON-IMPACTED GROUNDWATER <br /> A total of six grab ground water samples collected from soil borings and analyzed for the <br /> constituents listed in Section 2.2. The following target analytes were detected: <br /> Advanced Geo Environmental,Inc. <br />
