The regional groundwater flow is to the south or south southeast in the site vicinity Existing <br /> site water elevation data (from two wells) suggest that groundwater flow is likely to the east or <br /> southeast <br /> Because of the single elevated TPH-G soil concentration found, a prudent measure would be to <br /> excavate and remove the soils in the SB-2 area The upper 15 or greater feet of soils are fill <br /> over a ramp into the former excavation, which could be removed and stockpiled for use as <br /> backfill Contaminated soils could be identified visually and by using an Organic Vapor <br /> Analyzer for screening Contaminated soils would be placed on plastic sheeting or in soil <br /> rolloffs pending disposal Confirmation samples would be collected to verify that cleanup <br /> objectives have been met, and then the excavation would be backfilled <br /> 1 <br /> i <br /> I ' <br /> I <br /> sn.utPrSWCMVCDI WP 7 08129'94 <br />
