EPA adds 150-mile Upper Columbia River stretch to Superfund list due to heavy metal contamination.

The Environmental Protection Agency (EPA) has added a 150-mile stretch of the Upper Columbia River in Washington to its Superfund list due to contamination from lead, arsenic, and other heavy metals. The pollution stems from a Canadian smelting facility and a former U.S. smelter. The designation will facilitate cleanup efforts and potentially secure federal funding for the process, addressing risks to human health and the environment.
