Abstract
An in situ system for thermally cleansing hazardous and toxic waste disposal sites is disclosed. The system includes a perimeter wall extending into the site which is sealed to a roof structure surrounding the site to encapsulate the site. A plurality of tubes are sunk into the encapsulated site in a geometric pattern and are directly heated to indirectly heat the site. In time, the temperature of the entire site is raised to a level where the waste is volatilized and the volatiles are collected in the roof and subsequently incinerated.
