21 May 2002 AGE-NC Project No. 02-0930 Page 3 of 4 ANALYTICAL RESULTS OF SOIL SAMPLES - - detected in soil samples B2-10, B2-15, B5-10, B5-15 and B�-20 at concentrations of TPH-g was 120 mg/kg, 220 mg/kg and 5.7 mg/kg, t 130 milligrams per kilogram (mg/kg), 170 mg/kg, -mo were detected in each of the samplesectiveel,and borings respectively.TPH-d and TPH o was res B-2 and B-5 at concentrations as high as 970 mg/kg and 1,300 mg/kg, p . None of the target TPH analytes were detected in the soil detected in sample B 1-10 at 7.0 mg/kc,,, samples collected from probe borings B-3 and B-4. VOCs and SVOCs were not detected at or above laboratory reporting limits in soil sample B5-15 IDs 0205159- 5159- A copy of the laboratory report(MAI Laboratory 17 gh0205159-020) 05 through59-0 0)is included5159-007, 010,0205159-011,0205159-014,020515.9-015 and 0205159 O1 in Appendix B. DISCUSSION release of petroleum The detected concentrations of TPH-g, TPH-d and TPH-moi s indicate ettanalytes were detected hydrocarbons occurred at the site. The highest concentrations g between depths of 10 and 15 feet bsg and decreased significantly in the soil samples collected from 20 feet bsg. The lateral extent of hydrocarbon-impacted soil is defined to the west and east;the lateral extent to the north and south and the vertical extent are not well defined. RECOMMENDATIONS AGE recommends preparation of a work plan to delineatewater has been lateral and n dvertical extent of hydrocarbon-impacted soil and to determine If ground LIMITATIONS Our professional services were performed using that degree of care and skill ordinarily exercised by environmental consultants practicing in this or similar localities. The findings were based mainly upon analytical results provided by an independent laboratory.Evaluation of the geologic conditions at the site for the purpose of this investigation was made from a limited number of available data points(i.e. soil samples) and subsurface conditions may vary away from these data points.No other Advanced GeoEnvironmental,Inc.
