We are pleased to welcome Audrey Rhodes as a summer research assistant at the Center for Urban Waters. Audrey will be working in cooperation with the Stormwater Equipment Manufacturer’s Association (SWEMA) to analyze the effectiveness of new stormwater treatment technologies through literature reviews of published research. As part of her internship, she will work closely with experienced stormwater professionals to provide content for the SWEMA website such as social media, white papers, and short videos. Audrey was born and raised in Eastern Washington and received her Bachelor of Environmental Science degree from the University of Washington […]
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 until October 16th after which it may be revised and submitted to the Puget Sound Partnership’s Leadership Council for approval. The Washington State Department of Ecology is co-developing the strategy with the Department of Commerce […]
Few cities in the world can rival Seattle’s combination of money and brain power. It’s a town where the world’s two richest men live within walking distance. Amazon and Microsoft and hundreds of other leading tech companies call this region home, driving the economy and influencing the way we live. Could this same corporate culture also find a way to clean up Puget Sound? That’s the question behind The Nature Conservancy’s Water 100 Project. The project, with the input of scientists and policymakers and support from Boeing, is curating a […]
This is a guest blog from Partners in Puget Sound Recovery, an inter-agency group focused on strategies for stormwater mitigation, habitat protection and shellfish recovery in Puget Sound. Project Spotlight: Replicable Model for Depave and LID Retrofits Overview: This project will conduct three depave and retrofit activities providing direct stormwater benefit to three communities resulting in the removal of up to 15,000 square feet of excess pavement and the infiltration of up to 360,000 gallons of stormwater annually. What we are doing: These activities will provide case studies for the development […]
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 findings were presented this month in the journal Environmental Science & Technology and elevate tires as a prime suspect in “urban runoff mortality syndrome,” a condition that has been endangering coho salmon runs in the region. For […]
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 as they are happening. Kolodziej’s team will then collect water and tissue samples from these sites that they will analyze at the labs of PSI’s parent group the Center for Urban Waters. Project summary In […]
Stormwater may be Puget Sound’s most well-known pollutant, and at the same time its least known. While the state has called stormwater Puget Sound’s largest source of toxic contaminants, scientists are still having a tough time answering two basic questions about it: What is stormwater, exactly, and what does it do? Our magazine Salish Sea Currents looks at efforts by researchers to identify toxic chemicals in stormwater that may be killing large numbers of coho salmon in Puget Sound.
This much we know: Stormwater is nasty stuff. The state of Washington has called it one of the leading threats to the Puget Sound ecosystem. It can kill salmon within hours and it contributes to all kinds of health problems for species ranging from orcas to humans. What we don’t know, however, is exactly what’s in it. Rain and snowmelt wash an untold number of toxic chemicals from our streets and other impervious surfaces directly into our waterways, but there is no such thing as typical stormwater. It simply includes […]

Scientists know this much about stormwater: It can be extremely toxic. It can kill exposed fish such as coho salmon within hours. But figuring out exactly what is in stormwater has been a complex puzzle that has so far confounded scientists. Many of the chemical compounds in it remain unidentified. Is there such a thing as typical stormwater, or is it so variable that patterns can’t be detected? That has been the subject of research by Center for Urban Waters research scientist and PSI collaborator Ed Kolodziej, who will be presenting some […]
Many groups have been formed around the goal of saving salmon, but few people talk about a concerted effort to save microscopic creatures. Whether or not a pro-bug movement catches on, future strategies to save salmon are likely to incorporate ideas for restoring streambound creatures known as benthic invertebrates.
