_ 16 March 2000 <br /> AGE-NC Project No. 99-0683 <br /> Page 5 of 5 <br /> detected at concentrations of 0.070 mg/kg and 0.026 mg/kg, respectively (B3-20). Analytical results <br /> of soil samples are summarized in Table 1. The laboratory report (McCambell Analytical Inc. Lab <br /> I.D. 30905, 30907. 30911 through 30913, 30917, and 30919) and chain-of-custody are included in <br /> Appendix B. <br /> 5.0. SUMMARY AND CONCLUSIONS <br /> Based on review of a regional ground water elevation map published by the SJCFCD,the prevailing <br /> ground water flow direction in eastern Stockton is generally toward the east. <br /> Based upon data collected on 09 February 2000, AGE concludes the following: <br /> • Laboratory and field data suggest that the soil enclosed by B 1, B2, and B3 is not significantly <br /> impacted by petroleum hydrocarbons. <br /> 6.0. RECOMMENDATIONS <br /> Based upon data collected from the site, AGE recommends: <br /> • This site be considered for closure due to a minimum volume of hydrocarbon impacted soil <br /> at the site. <br /> • The stockpiled soil be used to backfill the excavated tank pit. <br /> 7.0. LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily exercised by <br /> environmental consultants practicing in this or similar localities. The findings were based mainly <br /> upon analytical results provided by an independent laboratory. Evaluations of the geologic/ <br /> hydrogeologic conditions at the site for the purpose of this investigation are made from a limited <br /> number of available data points (i.e. soil samples) and subsurface conditions may vary away from <br /> these data points. No other warranty, expressed or implied, is made as to the professional <br /> recommendations contained in this report. <br /> — Adrnnced GcuF.mironnrental,Inc. <br />
