07 April 1999 <br /> • AGE-NC Project No. 98-0481 <br /> Page 3 of 3 <br /> samples are below USEPA-recommended PR <br /> Gs for residential soil and may possibly be indicative <br /> of background concentrations. <br /> Based on the laboratory results for the soil samples collected in January 1999, as well as an <br /> estimated depth to ground water of greater than 60 feet below ground surface, the concentrations of <br /> TPH-d and metals in the soil stockpile do not appear to present a significant threat to ground water <br /> or environmental health. <br /> Recommgndations <br /> Based on the reported analytical results for the soil samples collected in January 1999, AGE <br /> recommends that the stockpiled soil be considered for on-site disposal. It is AGE's understanding <br /> that the property owner would like to spread the soil of the adjacent parcel for grading purposes. The <br /> stockpiled sail appears suitable for grading � p g g <br /> process would result <br /> in additional mixing and aeration f thesoilmay pot ntially the grading educe the residual <br /> petroleum hydrocarbon concentrations. <br /> If you have any questions or require further information,please contact our office at(209)467-1006. <br /> Sincerely, <br /> Advanced GeoEnvironmental, Inc. :, �;• <br /> Gary A.
