The federal Environmental Protection Agency on Tuesday put the former copper smelter and refinery property in Black Eagle on the federal Superfund list, citing the threat of remaining pollution to public health and the environment.
The 427-acre site contains heavy metals contamination from historic smelting and refining activities, according to the EPA. Operations began in 1893 and ceased in 1980.
Residential soils in Black Eagle and the Missouri River also will be investigated for potential cleanup, the EPA announced.
