The U.S. Environmental Protection Agency on Thursday added Bradford Island and surrounding waters of the Columbia River to its Superfund list of toxic waste sites, beginning the process for the eventual cleanup of the area.
The U.S. Army Corps of Engineers, which operates nearby Bonneville Dam, for years dumped toxic waste on the island, located 40 miles (63 kilometers) east of Portland, Oregon, and into a portion of the river. That waste contaminated fish caught and eaten by humans.
