ABSTRACT:
A method of disposing of toxic (e.g. radioactive) wastes, and related waste containment facilities, allow local long term containment of wastes in a cost-effective manner, while controlling to innocuous levels the release of contaminants. A cavity is provided in the ground below the level of the groundwater table, and a continuous pervious zone of natural, durable material is disposed about the interior of the cavity. A filter zone of natural, durable material is disposed within the pervious zone, and has materials of a grain size and gradation common to conventional graded filter materials. A waste disposal zone is provided within the filter zone, the disposal zone for receiving waste deposits, and a cover is placed over the cavity. The cover is a continuation of the filter zone, and the pervious zone over the cavity, and beneath the level of groundwater table, so that the groundwater level reinstates over the deposited waste.
