An in situ waste treatment system for contaminated soil employs a high temperature energy probe which is lowered into a borehole casing that has been inserted into the contaminated soil. The energy probe is activated and then melts surrounding region of the contaminated soil. The probe is raised and continues to melt a cylindrical column of soil that surrounds the borehole casing. Oxygen is introduced into the molten material so that organic and metallic components thereof are oxidized. In basaltic soils superheating and nucleation materials are introduced to enhance formation of a crystalline structure in the contaminated soil as it solidifies. Increased crystallinity makes the resultant solidified basaltic materials more resistant to leaching by ground water. Other types of contaminated soils are treated with waste modifiers to produce optimum leach resistance of the resultant resolidified soil.

Apparatus for in situ treatment and oxidation of waste materials in contaminated soil comprising: a movable energy probe capable of melting the contaminated soil; means for introducing the energy probe into the contaminated soil to a predetermined depth; means for activating the energy probe after the probe is inserted to the predetermined depth; means for maintaining the energy probe at a predetermined location for a period of time sufficient to permit at least about one cubic foot of adjacent contaminated soil to become molten; means for introducing oxygen rich substances to the molten soil; and means for controlling the amount of introduced oxygen to (a) preclude a reducing reaction between any carbon bearing components and any metallic components of the waste materials and to (b) produce metallic oxides from the metallic components which oxides dissolve into the molten waste material.
