The company responsible for cleanup at the Columbia Falls Aluminum Company Superfund site released results of their site evaluation on Thursday. 

The evaluation confirms that groundwater beneath the former aluminum smelter facility has elevated levels of cyanide, fluoride and other contaminants, leached from legacy landfills used from 1955 until 1980. The studies also indicate that the contamination is not moving toward wells used for drinking water in nearby neighborhoods.
