Abstract: A method of feeding a contaminated soil to a remediation apparatus to generate a clean soil and mixing the contaminated soil with an aqueous cleaning solution to generate a soil solution. The method also includes subjecting the soil solution to vortical flow in a first direction and subjecting the soil solution to vortical flow in a second direction in an opposite lateral direction from the first direction. The clean soil can then be separated from a dirty aqueous solution. A remediation apparatus used to clean the contaminated soil that includes a chamber having a soil inlet for receiving a contaminated soil and a soil outlet. The chamber is angled downward from the soil inlet to the soil outlet to facilitate the flow of the soil solution through the chamber.
