Abstract : Metals contaminated soils are a problem at many US Army sites. In an effort to identify options for treatment of heavy metal contaminated soils and residues, the US Army Toxic & Hazardous Materials Agency (USATHAMA) initiated this study which is an evaluation of treatment technologies which may be candidates for further research and development. The first part of study involved the characterization of soil metal concentrations at the various sites and a review of applicable regulations guidelines/criteria for residual soil metal concentrations. These characterizations indicated that several Army installations had elevated total metal concentrations in their soils and Chromium, Cadmium and Lead were the most prevalent. This feasibility screening resulted in the following technologies being selected for further research and development: Microencapsulation, Roasting, Extraction. Keywords: Soil contamination, Heavy metals, Soil treatment technologies, Innovative technologies, Soil decontamination, Thermal treatment, Physical treatment, Chemical detoxification, Roasting/Slag, Microencapsulation, Extraction of metals, Immobilization of metals.
