Abstract
A process for removing water-soluble contaminates from soil includes laying a mat over and in contact with the contaminated soil, applying water to the soil, permitting the water to be transferred from the soil to the mat, permitting the contaminants to be carried via the water into the mat, and permitting the water to be evaporated from the mat so that the contaminants precipitate in the mat.
