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 […]

Identifying chemical suspects in stormwater
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 […]

Where does Seattle coffee go after it’s poured down the drain?
PSI’s Director Joel Baker was quoted in a story by KIRO News on how caffeine and other chemicals like Prozac find their way into Puget Sound. “Scientists like Dr. Baker say caffeine levels in our waters have not reached a crisis level,” KIRO reports, “but the studies point out why in the future, technology must […]

The impacts of rogue chemicals on Puget Sound
In early 2016, scientists at NOAA made headlines when they reported finding 81 different man-made chemicals in the tissues of juvenile chinook salmon in Puget Sound. Among those chemicals were drugs such as cocaine and Prozac. This was the first time scientists had made these findings for the region’s salmon, but it has been well-understood that marine […]

In the news: Radiolab event will feature PSI’s water detectives
There is a nice story in The News Tribune today on the upcoming Radiolab event in Tacoma. The January 22nd show at the Pantages Theater will focus on Northwest water issues and features a panel of environmental leaders, including PSI Director Joel Baker. The paper calls Joel and his lab “the ‘CSI’ of water science” and highlights some of their research into the high […]

New papers look at ‘zombie’ steroids
They are sometimes called ‘zombie’ chemicals. Some compounds thought to be safe and inactive can change into dangerously active forms when they are exposed to the environment. Two recent papers co-authored by PSI collaborator Ed Kolodziej look at some of the ways that regulators may need to account for these transformations. Cole, EA, McBride, SA, Kimbrough, KC, Lee, J, Marchand, […]

UW scientist studies how pharmaceuticals impact the environment
Dr. Ed Kolodziej is one of the Puget Sound Institute’s newest collaborators. Kolodziej began his appointment at the University of Washington Department of Civil and Environmental Engineering last fall with a joint appointment at Interdisciplinary Arts and Sciences at UW Tacoma. His research looks at some of the ways that organic compounds like steroids and […]

From Puget Sound to Everest: water quality studies may aid climbers
By Jeff Rice Scientists at the Puget Sound Institute (PSI) and the Center for Urban Waters have taken their research to the highest place on earth. The same techniques used to analyze water quality in Puget Sound are being applied at Everest base camp. Water samples were collected on the mountain and sent back to […]
