1 <br /> The samples collected at a depth of 12' bgs in PH-4 and PH-5 indicated gasoline levels of 2,700 <br /> tmg/Kg and 1,200 mg/Kg, respectively. The samples collected at 15' bgs indicated a significant <br /> • decrease to 750 mg/Kg and 21 mg/Kg, respectively. <br /> The 15' bgs samples collected in PH-6 and PH-7 showed low levels of gasoline and BTEX <br /> constituents. Gasoline was found at a level of 5.9 mg/Kg at PH-6 and at a level of 320 mg/Kg at <br /> 1 PH-7. Benzene was below the laboratory detection limit for both samples. <br /> ' Table 3 <br /> Additional Soil Investigation <br /> Soil Sample Analytical Data <br /> Analyte <br /> Location Depth Benzene Toluene Ethyl Xylene TPH Gas PID <br /> ' (µg/Kg) (µg/Kg) Benzene (µg/Kg) (mg/Kg) Reading <br /> (Fig/Kg) (ppm) <br /> ' 10' NA NA NA NA NA 1183 <br /> SW-9 12' ND 3,100 30,000 130,000 2,900 904 <br /> (PH-1) 14' NA NA NA NA NA 518 <br /> ' 16' NA NA NA NA NA 598 <br /> 18' NA NA NA NA NA 328 <br /> PH-2 15' ND 3,000 17,000 41,000 1,900 463 <br /> SW-13 12' ND ND 4,000 4,200 510 568 <br /> (PH-3) <br /> 12' 5,800 11,000 77,000 150,000 2,700 468 <br /> PH-4 15' 360 1,900 5,600 2,000 750 653 <br /> 18' ND ND ND ND ND 0.0 <br /> ' 12' ND 3,600 7,500 1,900 1,200 802 <br /> PH-5 15' ND ND 170 350 21 635 <br /> 18' ND ND ND ND ND 0.0 <br /> ' 12' NA NA NA.
