Abstract
There is described a prefabricated floating raft of low density modules, which are trucked into the polluted land site, and lifted into place over the polluted land area. The surface is sealed with an impervious plastic cover, and a thin layer of gravel and top soil is placed on top, with grass or other suitable vegetation. The center to edge is arranged at a small slope to provide rain runoff. The perimeter of the area is surrounded by a deep concrete wall and gravel-filled moat to catch the runoff water. The runoff water forms a perimeter seal that provides clean ground water to the radial area surrounding the covered area, and seals in the pollution below it.
