Abstract
There is described a process in which a contaminated soil is freed of its contaminants and the solvent used to free and wash the contaminated soil is collected and reused and/or it is combusted and removed from the system in a form which will not contaminate the ambient atmosphere. All portions of this equipment are substantially gas tight and liquid tight and therefore eliminate or markedly reduce any further contamination of the ambient atmosphere with the contaminants found in the soil.
