' 9.0 RECOMMENDATIONS AND PROPOSED REMEDIATION <br /> STRATEGY <br /> ' It is proposed that the most feasible strategy for remediation of the Tracy Cold Storage <br /> site would be as follows <br /> 1 Excavate the high level soil contamination in the vicinity ty of the old UST <br /> ' Uncontaminated soil will be stripped and set aside for backfill and <br /> Contaminated soil will be excavated and stockpiled on site <br /> 2 Excavation will proceed outward from the source area until soil <br /> contamination is confined to the smear zone of the water table <br /> 3 Remediation of excavated soils will be carried out either by ex-situ soil <br /> vapor extraction or bioremediation <br /> 4 Monitoring of ground water will continue on a semiannual basis It is <br /> recommended that sampling of only four wells be carried out--MW-1, <br /> MW-4, MW-6, and MW-8 Wells MW-2 and MW-3 should be destroyed <br /> i 10.0 REMARKS AND SIGNATURES <br /> This report has been prepared by American Geological Services, Inc for the Tracy Cold <br /> Storage site The data and information used in the preparation of this report was believed <br /> to be complete and accurate at the time of writing, however, AGS makes no warranty as <br /> to the completeness or accuracy of the data obtained from outside sources As such, any <br /> recommendations or conclusions based upon such data are subject to revision as deemed <br /> necessary <br /> All aspects of this investigation were performed by AGS in accordance with applicable <br /> laws, regulations, geologic and hydrologic standards in effect at the time of this writing <br /> At no time is any warranty, either express or implied, made with respect to the geologic <br /> or hydrologic conditions beneath the Tracy Cold Storage site <br /> i <br /> ' American Geological Services, Inc <br /> CA95DE-029 <br /> 18 <br />
