Abstract: As many as 69 different organic compounds and 24 metal species can be found in ground water underlying the 85 acre Bofors-Nobel Superfund site in Muskegon County, Mich., a testimony to a history of industrial chemical manufacturing in which process wastes were routinely discharged into unlined lagoons and settling ponds. Although the owners attempted to treat the ground water with powder-activated carbon treatment, their early efforts were insufficient. In 1987, following owner bankruptcy, the Michigan Department of Natural Resources (MDNR) pressed for federal cleanup. In September 1994, a 1.1 mgd continuous-flow plant based on ultraviolet oxidation officially went on line at Bofors-Nobel. Designed by the U.S. Army Corps of Engineers' Omaha (Neb.) District and built by Sverdrup Corp., St. Louis, the $12.4 million facility is one of the largest government-built ground-water pump-and-treat systems in the nation. The plant's treatment system is unusual in that it combines ultraviolet oxidation with ammonia stripping as well as other processes such as metals precipitation and carbon adsorption.
