26 September 1997 <br /> AGE-NC Project No 97-0330 <br />' Page 5 of 7 <br />' one sample for analysis TPH-d was detected in a soil sample collected from P-4 at 25 feet (P4-25) <br /> at a concentration of 1 2 parts per million (ppm, reported as milligrams per kilogram) and from the <br /> composited stockpiled soil (SP 1-3) at a concentration of 4,700 mg/kg The laboratory analysis did <br /> not detect benzene, toluene, ethylbenzene or xylenes from any soil samples collected from P-4, <br /> however, toluene, ethylbenzene and xylene were detected from the composted stockpiled soil sample <br /> at concentrations as high as 0 12 ppm <br /> Samples P4-25 and SP 1-3 were analyzed for PNAs The laboratory atory analysis did not detect PNAs <br /> from P4-25, however, fluorene, naphthalene and phenanthrene were detected from SP 1-3 at <br /> concentrations of 1400 parts per billion (ppb, reported as micrograms per kilogram), 1600 ppb and <br /> 2400 ppb, respectively <br /> Analytical results of soil samples are summarized in Table 1 -Analytical Results of Soil Samples <br /> Figures 3 depicts the estimated extent of contoured TPH-d concentrations beneath the site in cross <br />' sectional view The laboratory report (MAI Identification No 80395 to 80408) and chain-of-custody <br /> are included in Appendix B <br /> 44 ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> A total of two ground water samples from P-3 (P3-H20) and P-4 (P4-H20) were submitted to MAI <br /> for analysis for TPH-d and BTEX TPH-d was detected in ground water samples collected from P-3 <br /> and P-4 at concentrations of 510 ppb and 70 ppb (reported as micrograms per liter), respectively The <br /> laboratory analysis did not detect benzene, toluene, ethylbenzene or xylenes from ground water <br /> samples collected from P3-H20 or P4-1-120 <br /> Samples P3-1UO and P4-1120 were analyzed for PNAs The laboratory analysis did not detect PNAs <br /> from the two ground water samples <br /> Analytical results of ground water samples are summarized in Table 2 -Analytical Results of Ground <br /> Water Samples The laboratory report (MAI Identification No 80399 and 80400) and chain-of- <br /> custody are included in Appendix B <br /> 5-0. SUMMARY AND CONCLUSIONS <br /> Based upon field data and laboratory analysis of soil and ground water samples collected at the site <br /> on 14 May 1997 and 02 September 1997, AGE concludes the following <br /> Substantial concentrations of TPH-d were detected from soil probe boring P-1 at a depth of <br /> Advanced GeoEnviromnentai,Inc <br />
