• 1 I <br />' 05 September 2002 <br /> AGE-NC Project No 02-0927 <br /> Page 5 of 6 <br />' Petroleum hydrocarbon- odor and organic vapor was detected in each of the soil samples <br /> Y _ <br /> collected PID data is included on the boring logs (Appendix A) <br />' 42 ANALYTICAL RESULTS OF SOIL SAMPLES <br /> Soil samples P7-35, P7-45 and P7-50 were analyzed for TPH-g, BTEX and fuel additives TPH-g <br />' was detected in the three soil samples at concentrations of 1,300 mg/kg, 6,700 mg/kg and <br /> 2,300 mg/kg, respectively BTEX compounds were detected in each of the analyzed soil samples at <br /> concentrations as high as 39 mg/kg(benzene), 330 mg/kg(toluene), 130 mg/kg (ethylbenzene) and <br />' 710 mg/kg (xylenes) from sample P7-45 <br /> MTBE and other fuel additives were not detected at or above laboratory reporting limits in the three <br />' analyzed soil samples Analytical results of soil samples are summarized on Tables 1 and 2 The <br /> laboratory report(CTEL Laboratory IDs 0208-033-4,0208-033-6 and 0208-033-7),qualityassurance <br />'• and quality control (QA/QC) report and chain-of-custody forms are included in Appendix B <br />' 4 3 ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> A grab ground water sample was collected from the probe boring and analyzed for TPH-g, BTEX <br />' and fuel additives, including MTBE TPH-g was detected at concentrations as high as <br /> 12,000,000 gg/l BTEX compounds were detected at concentrations of 60,000 µg/1 (benzene), <br />' 490,000 µg/l (toluene), 310,000 µg/l (ethylbenzene) and 1,890,000 µg/l (xylenes) <br /> MTBE and other fuel oxygenates were not detected at or above laboratory reporting limits in the <br /> ground water samples analyzed Analytical results'of grab ground water samples are summarized on <br /> 1 Tables 3 and 4 The laboratory report (CTEL Laboratory IDs 0208-033-8), quality assurance and <br /> quality control(QA/QC) report and cham-of-custody forms are included in Appendix B <br /> 1 - , <br /> 5.0. SUMMARY AND CONCLUSIONS <br /> 1 <br /> Based upon data collected on 06 August 2002, AGE concludes the following' <br />' Generally, light to moderate yellowish brown, damp to saturated, silt and silty sand were <br /> . encountered from approximately 20 feet bsg to 50 feet bsg Moderate yellowish brown, <br /> damp,silty lean clay was encountered at 30 feet bsg A boring log is included in Appendix A <br /> i y <br />' Advanced GeoEnvlronmental,Inc <br />
