"> Ecology, EPA now under the gun to adopt new water quality criteria for aquatic creatures
Long delays in updating state water-quality standards to protect orcas, fish and other aquatic species appear to have finally caught up with the Washington Department of Ecology and its federal counterpart, the Environmental Protection Agency. In a court ruling this week, U.S. District Judge Marsha Pechman of Seattle found that Ecology has “abdicated its duties” […]

"> Science during the year of Covid: The Puget Sound Marine Waters Overview
While Covid restrictions remain a part of everyday life, a lot has eased since the global quarantines of spring 2020. During that time, the coronavirus effectively shut down scientific fieldwork in Puget Sound, leaving huge gaps in data for most facets of the ecosystem. Despite the lockdowns, a new report from the Puget Sound Ecosystem […]

"> Washington’s Water Quality Assessment offers insights into status of pollution
More than 2,000 segments of streams, lakes and marine waters have been added to the state’s massive list of water-quality data, allowing more Washington residents to take stock of pollution levels near their homes. The latest Water Quality Assessment for Washington waters, released for public review this week, covers 9,279 miles of streams, 434 lakes […]

"> New sewage-treatment permit would be a step to curbing nitrogen in Puget Sound
In an effort to stem the flow of excess nitrogen into Puget Sound, Washington Department of Ecology has proposed a new type of permit for some 60 sewage-treatment plants operating throughout the region. The flexible permit, called the Puget Sound Nutrient General Permit, aims to hold nitrogen releases close to or below their current levels […]

"> Are some streams in Puget Sound getting cleaner?
Scientists are reporting some potentially good news about the health of Puget Sound’s streams. Ten years of data from 126 stream sites within King County have shown a slight improvement in water quality, according to the county’s Water and Land Resource Division. The study examined the variety of insects and other invertebrates that were collected […]

"> Video: Identifying sources of pollution in the Skagit Valley
A video produced by the University of Washington Center for Urban Waters shows how chemical tracers can identify sources of pollution affecting shellfish growers in Puget Sound’s Skagit Valley. Fecal coliform pollution is a widespread problem in Puget Sound, resulting in costly beach and shellfish bed closures whenever it is detected. Analytical techniques can now […]

"> Puget Sound’s growing nutrient problem
By Jeff Rice, Puget Sound Institute First there was “The Blob” that fed last year’s massive algae bloom in the Pacific Ocean. Now there is another monster getting our attention. You might call it “The slime that ate Lake Erie.” The incredible images of Lake Erie’s expanding blanket of green show the familiar effect of […]
