Abstract
A thermal method of in-situ soil treatment using a charge of combustible substrate placed within the area to be treated and combusted with the use of oxidizer resulting in solid products and generating no gases. The substrate can be a metal, such as aluminum or iron, and oxygen can be an oxidizer. Alternatively, thermite mixtures can be used. The treatment of soil constituents and pollutants can be achieved by vaporizing, pyrolyzing, incinerating, oxidizing, reducing, or vitrifying the constituents of pollutants and the soil in the zone of influence of the charge of the combustible substrate.
