The US Environmental Protection Agency has both sponsored several extramural research projects and conducted in-house research on uranium removal treatment. This article summarizes recent information on the effectiveness of various treatment methods to remove uranium from drinking water supplies. Because uranium is found in both surface water and groundwater, a variety of methods have been studied. Most of the information presented here, however, was developed from either laboratory or pilot-plant studies because only limited data exist on full-scale treatment systems. Includes 15 references, tables, figures.
