We screened the stockpiled soils which separated cobbles from the screened soils which was contaminated and exported to Wenatchee Landfill. All screened cobbles were used for backfill in the water table and sand was imported for backfill materials. We treated the groundwater by using baker tanks and carbon filters to treat and pump back into the ground
