Wastewater

A new report from the Puget Sound Institute and the University of Washington School of Aquatic and Fishery Sciences examines a species-level approach to oxygen risks in Puget Sound. Case studies of Dungeness crabs, English sole, and Chinook salmon provide new details on when and where individual species may be most vulnerable.

The Washington State Department of Ecology is responding to new legal rulings and public concerns with changes in planning and potentially future enforcement. We continue our occasional series on water quality and wastewater management in Puget Sound. Funding for the series is provided in part by King County.

Increasing concerns surround PFAS in products from wastewater treatment plants. How great a risk do they pose, and are there feasible approaches to removing them?

Scientists at the Washington Department of Ecology along with many other researchers have spent years studying and debating the problem of low oxygen in Puget Sound. Now, many new developments — technical, scientific and legal — are reaching a critical stage and setting up a framework to make some major decisions. This is part four of a four-part series originally published in the Puget Sound Institute blog.
