Landfill Cap Soil   Pump-and-treat system pulls TCE from ground water below landfill

Landfill Cap Soil   The method developed involved contouring the top surface of each waste area into a berm shape. Two feet of clay was highly compacted to a permeability of 1x10-7cm/s. The clay was then covered with 30-mil polyvinyl chloride (PVC) welded into one piece. A drain net with a filter on top was then placed on top of the PVC in lieu of the normal 1 ft of sand to allow the water to drain as much as possible before reaching the PVC. Two feet of earth was placed on top to provide for green cover growth (engineered caps).

John Kornuc, NFESC, (805) 982-1615

Water Harvesting Vegetative Cover Soil (landfill)   All plots are equipped with instruments to monitor daily precipitation, percolation, runoff and sediment yield, and soil moisture in order to compute a water balance for each design. Evapotranspiration is estimated. Automated data acquisition systems are used for most of the measurement variables. Periodic measurements of species composition, biomass, canopy cover, ground cover, and leaf area index will also be taken of the vegetation cover on each plot.   In FY94.
