• LANDFILL
  
  A landfill is an enormous hole, either excavated for the purpose of waste disposal or left over from a surface mining operation. The hole is lined with clay or a synthetic lining to prevent leakage of waste into the surrounding water supply. Waste is laid on the liner at the bottom of the landfill and a layer of topsoil is then compacted into the waste. The layering is repeated again and again until the landfill reaches its full capacity.
