This report contains current information on the treatment technologies for wastes and environmental media containing arsenic. It summarizes information on 13 technologies used to treat arsenic, identifies sites and facilities where arsenic treatment has been used, and provides references to more detailed arsenic treatment information. The information can be used to help identify and screen treatment technologies that can meet the lower arsenic maximum contaminant level (MCL). The technologies included in the report to address soil and solids are: solidification/stabilization, vitrification, soil washing/acid extraction, pyrometallurgical treatment, and in situ soil flushing. Technologies for water include: precipitation-coprecipitation, membrane filtration, adsorption, ion exchange, permeable reactive barriers, and biological treatment. Two technologies discussed in the report address soils, other solids, and water: electrokinetics and phytoremediationYou may need a PDF reader to view some of the files on this page.
