<p>The method essentially creates a lake (16), if one does not already exist, and uses this lake as a 'moving' biological treating pond for contaminated soil sites (6). Contaminated soil (14) from one side of the lake is dragged into the lake, the water of which is infested with contaminant-consuming micro-organisms, then is tilled at the bottom of the lake to fully expose the soil to biological treatment, and then is raked upwardly along an opposite side of the lake to form a shoreline of cleaned soil material (14b). The earthmoving process is repeated until the lake has passed through and treated all of the contaminated soil site. The method performs all decontamination on-site and avoids the requirement for any backfilling of the site after decontamination of the site.</p> |
