The excavation may be enlarged if high concentrations of contaminants are still detected in the soil.' All impacted soil will be stockpiled on site for sampling and later disposed of at an appropriate landfill. All soil -determined to be free of contamination based on field observations and OVM readings will be returned to the excavation pit during' backfilling; additional clean soil will be placed into the excavation as necessary. In the event that ground water is encountered site preparations WMII include submersible pumps and appropriate holding tanks to properly remove :A and treat ground water.GE may determine that it is necessary to trench along the western portion of the property to minimize the influx of ground water to the site.
