The Acid Extraction Treatment System (AETS) reduces the concentrations and/or leachability of heavy metals in contaminated soils so the soil can be returned to the site from which it originated. The objective of the project was to determine the effectiveness and commercial viability of the process. An account of the activities conducted during the project, the experiments performed, results and conclusions, are included in the report. A pilot-scale AETS was used to treat 5 different soils containing different combinations of seven heavy metals. The AETS can, in most cases, treat the entire soil, with no separate disposal or stabilization of the clay fines needed. The estimated treatment costs are between $80 and $180 per cubic yard.
