ABSTRACT:
An advancing freeze front is established in a porous region adjacent to or within contaminated earth. A flow of contaminated liquid phase water migrates toward the freeze front and a concentration of impurities is established in front of the advancing freeze front. When the freeze front reaches a collection zone, at least a portion is melted and the resultant water bearing concentrated impurities is collected and removed. This process may be repetitively performed.
