CA 2111279

A process for the in-situ remediation of contaminated soil comprising: (a) forming at least one liquid permeable region within a contaminated soil region, (b) introducing material for treating contaminants in the contaminated soil region into the liquid permeable regions to form at least one treating zone within the contaminated soil region, and (c) transmitting direct electric current through the contaminated soil region between a first electrode and a second electrode having opposite charge, wherein the first electrode is located at a first end of the contaminated soil region and the second electrode is located at the opposite end of the contaminated soil region to cause an electroosmotic flow from the second to the first electrode.
