Coho Salmon have been dying off in urban areas of the Pacific Northwest for years. Scientists have been working hard to figure out why, but have thousands of chemicals to sort through that enter creeks through storm runoff.

Edward P. Kolodziej is an Associate Professor at the University of Washington with a Civil and Environmental Engineering background and currently working at the Center for Urban Waters. He was part of a study that isolated the preservative compound 6PPD found in tires as the culprit responsible for killing coho salmon.
Edward joins the Zero Waste Countdown from Tacoma to tell us all about the study, why salmon are so important to the health of our ecosystems, how the culprit was found, and what we can do going forward to prevent salmon die-offs.
