A sanitary LANDFILL is a low-lying area that is filled with WASTE REJECTS. It has a liner at the bottom to prevent the groundwater from contaminating with the mix of the liquid that oozes from the waste that is buried called the leachate. Waste is buried in-between layers of soil and is compacted nicely to make it a hard surface. When the landfill is completed, it is capped with a layer of clay or a SYNTHETIC liner in order to prevent water from entering. A final topsoil cover is placed, compacted and graded, and VARIOUS forms of vegetation may be planted in order to reclaim the otherwise useless land.
