5.0 FINDINGS AND RESULTS <br /> 5.1 SUBSURFACE CONDITIONS <br /> • Collected soil samples consisted of silty clay and silt at approximate depths of 10 through 20 feet <br /> bgs. <br /> • Groundwater was not encountered during drilling. Depth to groundwater in the vicinity of the Property <br /> is expected to be deeper than 20' bgs (see Section 3.3 of this Report). <br /> 5.2 ANALYTICAL RESULTS OF SOIL SAMPLES <br /> The results of ENCON's subsurface investigation are summarized as follows: <br /> • None of the analyzed soil samples had detectable concentrations of TPH-GROs <br /> • None of the analyzed soil samples contained detectable concentrations of BTEX or MTBE. <br /> • Detectable concentrations of TPH-DRO ranged from 2.44 mg/kg (SB3-20') to 8.28 mg/kg <br /> (SB7-20') <br /> • Detectable concentrations of TPH-ORO ranged from 8.04 mg/kg (SB5-20') to 22.7 mg/kg <br /> (SB7-20') <br /> • Metals concentrations of all samples collected and tested from areas of concerns were within <br /> expected background levels when compared to background levels of soil in Southern <br /> California (Bradford, Chang et al, 1996). <br /> Encon Solutions, Inc. <br /> -12- <br />
