Method for removing volatile liquid contaminates from a contaminated volume of earth

摘要

A method is provided to remove volatile liquid contaminates from a contaminated volume of earth, the contaminated volume lying above a non-contaminated layer of earth, the method including the step of heating the non-contaminated layer until the temperature of a substantial portion of the non-contaminated layer that is contiguous with the contaminated layer is at least the boiling point temperature of contaminated liquids so as to prevent vaporised contaminants to move downwards from the contaminated layer of earth.
