GAO report calls for strengthening of regulations on nonpoint source pollution

By Sarah DeWeerdt A new report by the nonpartisan Government Accountability Office (GAO) is renewing calls to strengthen Clean Water Act protections against nonpoint source pollution such as stormwater and agricultural runoff.  The recommendation echoes findings made by the GAO in 2013 when it called for Congress to revise “largely voluntary” regulations for nonpoint pollution sources that […]

Could tire discovery go beyond impacts on coho?

Scientists have suspected for several years that chemicals from tire wear particles are to blame for the deaths of thousands of coho salmon that have returned to spawn in Puget Sound’s urban streams. Sometimes referred to as “pre-spawn mortality” or “urban runoff mortality syndrome,” these deaths typically occur in streams near roads, and scientists have […]

New guidance for cleanup of toxics in Puget Sound

An EPA-funded team of scientists and other experts has completed draft recommendations for the future cleanup of toxic chemicals in Puget Sound. The group’s Toxics in Fish Implementation Strategy addresses pollutants such as PCBs and a slew of emerging contaminants that can affect species throughout the waterway. The strategy will be available for public review […]

Orca task force releases recommendations

By Jeff Rice The governor’s Southern Resident Orca Task Force released its final report and recommendations today, focusing on three key threats to Puget Sound’s endangered orcas: Lack of food, disturbance from noise and vessel traffic, and toxic contaminants. In all, the report makes 36 recommendations for recovering the fast-declining orca population, which now stands at […]

Chemicals from automobile tires suspected in coho deaths

Findings authored this month by University of Washington scientists at the Center for Urban Waters and their collaborators provide new insight into “urban runoff mortality syndrome” affecting Puget Sound coho.   By Jeff Rice Chemicals linked to automobile tires have been found in stormwater associated with the widespread deaths of coho salmon in Puget Sound. The […]

PSI collaborator receives NSF grant to study coho deaths

PSI collaborator Ed Kolodziej has received a $330,000 National Science Foundation grant to expand his research on toxic pollutants in Puget Sound. Kolodziej’s project will identify chemicals in stormwater that are killing coho salmon and endangering some spawning runs. The project includes a collaboration with citizen scientists who will alert project members to salmon die-offs […]

New studies on emerging threats to salmon

Chemicals, disease and other stressors can increase a salmon’s chance of being eaten or reduce its ability to catch food. We wrap up our series on the Salish Sea Marine Survival Project with a look at some of the lesser-known, but still significant factors contributing to salmon declines in the Salish Sea. Read the story in […]

Removal of creosote-treated pilings may assist herring recovery

Thousands of abandoned wood pilings — the ghosts of piers and docks past — are located throughout Puget Sound. Most of them are treated with creosote, a toxic chemical used to preserve wood that contains polycyclic aromatic hydrocarbons (PAHs), a class of chemicals that are also associated with oil spills and burning of fossil fuels.
