ABSTRACT:
A method for removing contaminants from soil site regions in which at least one source electrode is positioned in the soil site and is surrounded by a plurality of sink electrodes so that voltage gradients are established between the source electrode and the sink electrodes. A purging liquid is supplied to the source electrode and is permitted to flow therefrom into the soil site. The voltage gradients cause the purging liquid to move by electroosmosis through the soil site toward the sink electrodes to displace the contaminant material therein and to cause a substantial portion of the contaminant to be moved into the sink electrodes from which the contaminant can be removed.
