   Abstract:
   To reduce the risk of liner failures, to control cost, and to make landfills acceptable to the public, a design is suggested in which chemical leachate migration is prevented by artificially creating a reversed flow of water. In this design, the landfill is placed above the ground-water table. The liner of this facility is multilayered and consists of a leachate collection system to collect possible leachate moving downward from the waste disposal area as well as supply water moving upward, a compacted clay liner with a low hydraulic conductivity, sand and gravel to distribute supply water in the reverse flow operation, and a liner constructed either of compacted clay or synthetic material, or both, to act as a back-up barrier to the waste and to confine the water supplied for reverse flow.
