' 26 July 1999 • AGE-NC Project No 97-0301 Page 6 of 9 Analytical Inc) for analysis as noted above TPH-g was detected in soil samples collected from ' probe boring P-1 at concentrations ranging as high as 330 mgikg, however, the laboratory reported that unmodified or weakly modified gasoline and heavier gasoline range compounds were significant TPH-d was detected in soil samples collected from P-1 at concentrations ranging as high as 190 mg/kg, however, the laboratory reported that gasoline range compounds were significant BTEX compounds were detected in soil samples collected from P-1 and P-4 at concentrations ranging as high as 9 5 mg/kg,MTBE was not detected during by laboratory analysis of soil samples 1 Fuel oxygenated compounds were not detected during the laboratory analysis of selected soil samples Analytical results of soil samples are summarized in Table 2 The laboratory report (McCampbell Analytical Inc Lab ID 12647 through 12675) and chain-of-custody are included in ' Appendix B The estimated extent of petroleum hydrocarbon-impacted soil is depicted in cross sectional view A -A'in Figure 4 44 ANALYTICAL RESULTS OF GROUND WATER SAMPLES A total of four ground water samples were submitted to McCampbell Analytical Inc for laboratory ' analysis TPH-g was detected in ground water samples collected from P-1, P-2 and P-4 at concentrations ranging as high as 23,000 micrograms per liter (µg/l), however, the laboratory ' reported that unmodified or weakly modified gasoline was a significant component in the TPH-g ground water samples TPH-d was detected in ground water samples collected from P-1,P-2 and P4 at concentrations ranging as high as 350,000, g/1, however, the laboratory either reported that the diesel chromatograms for the samples did not have typical diesel characteristics,that gasoline range compounds were significant or that the medium boiling point patterns did not match diesel,but were more typical of kerosene during the TPH-d ground water sample analysis BTE&X compounds were detected in round water samples collected from P-1 though P-4 at p g concentrations ranging as high as 3,300 Azgll,the greatest benzene concentration was detected in P-1 1 at a concentration of 1,900 µg/l MTBE was not detected by laboratory analysis of ground water samples ' TBA was detected in ground water samples collected from P-1, P-2 and P-4 at concentrations ranging as high as 140 µg11, DIPE was detected in a sample collected from P-2 at a concentration of 1 2 µg/l No other fuel oxygenated compounds were detected by laboratory analysis of ground water samples Analytical results of ground water samples are summarized in Table 3 The • laboratory report(McCampbell Analytical Inc Lab ID 12676 through 12679) and chain-of-custody Advanced GeoEn.ironmentai,Inc
