$668 million settlement agreement advances cleanup of Seattle’s Lower Duwamish Waterway

U.S. federal and state authorities have reached a $668 million settlement agreement to support the long-term cleanup of the Lower Duwamish Waterway Superfund site in Seattle, marking a major step toward addressing decades of industrial contamination in the river system.

The agreement between the U.S. Environmental Protection Agency (EPA), the U.S. Department of Justice, and the state of Washington involves more than 100 potentially responsible parties. The cleanup effort is expected to take at least 10 years to complete.
