Groundwater at a Superfund site in west Texas has been found to contain chromium at concentrations exceeding EPA's drinking water standard of .05 mg/l. Alternative treatment methods for this site were investigated; this article presents the evaluation of a physicochemical treatment system, in which removal of total chromium to levels below the drinking water standard was achieved through reduction of hexavalent chromium and subsequent removal by coprecipitation with iron. Costs for the construction of the pilot and full‐scale systems are also discussed.
