..J6 21 September 2000 ,'. AGE-NC Project No, 97-0360 Page 6of8 4.3 ANALYTICAL RESULTS OF SOIL SAMPLES w,. A total of thirteen soil samples were submitted to a DHS-certified laboratory (McCampbell Analytical Inc.)for analysis as noted above.TPH-g was detected in the 10-foot soil sample collected from P4 at a concentration of 46 milligrams per kilogram (mg/kg). The only BTEX compound detected in soil was ethylbenzene,which was detected in the 10-foot soil ... sample collected from boring P4 at a concentration of 0.009 mg/kg. TPH-d was detected in soil samples collected from probe borings Pl, P4 and P5 at concentrations as high as 3,400 mg/kg (P4-10). Fuel oxygenated compounds were not detected at or above Iaboratory reporting limits. Analytical results of soil samples are summarized in Table 2. The laboratory report(McCampbell Analytical Inc.Lab I.D.42945 through 42957)and chain-of-custody 16' are included in Appendix B. 4.4 ANALYTICAL RESULTS OF GROUND WATER SAMPLES Grab ground water samples were collected from boring PI through P8, and were submitted to a `'+� DHS-certified laboratory for analysis as noted above. TPH-g was detected in the ground water samples collected from P1,P2,and P4 at concentrations of 3,100 micrograms per liter(µg/1), 1,300 µg11, and 2,100 µg/I,respectively. TPH-d was detected in the ground water samples collected from PI through P8 at concentrations as high as 2,900,000 µg/I (P4). BTEX compounds were detected in the ground water samples collected from PI and P4 at concentrations ranging as high as 5.5 µg/1;dissolved benzene was detected at concentrations as high as 3.7 µg/1 (PI). Dissolved MTBE was detected in the ground water sample from P4 at a ,,.. concentration of 8.2 µg/I utilizing EPA Method 8020 and confirmed at a concentration of 7.6 µg/1 utilizing EPA Method 8260. �. No other fuel oxygenated compounds were detected at or above laboratory reporting limits during the laboratory analysis of the ground water sample. Analytical results of ground water samples are summarized in Table 3. The laboratory report(McCampbell Analytical Inc. Lab ID 42958 through �- 42965) and chain-of-custody forms are included in Appendix B. V 4 Advanced GeoEnvironmentid,Inc. i...
