Description:

The Acid Extraction Treatment System (AETS) is intended to reduce the concentrations and/or teachability 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. The report summarized here is an account of the activities conducted during the project, the experiments performed, results and conclusions. A pilot-scale AETS system was used to treat 5 different soils containing different combinations of seven heavy metals. The study showed that AETS is capable of treating a wide range of soils, and reducing the TCLP metals to below the RCRA limits. 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 $240/yd3.
