Description This is an addendum to the original project plan. The addendum outlines location specifics for the 2025 monitoring of toxics in freshwater fish. In 2025, the Washington Department of Ecology’s Freshwater Fish Contaminant Monitoring Program focused on Columbia River sites between Stevenson, Washington, and McNary Dam. The toxics of concern at these sites were polychlorinated biphenyls (PCBs), chlorinated pesticides, and Polybrominated diphenyl ethers (PBDEs). Per- and polyfluoroalkyl substances (PFAS) are also being monitored to address data gaps.
