EVERETT — The Edmonds City Council unanimously approved a moratorium on development near Deer Creek on Tuesday following code changes that have raised difficulties for processing permits.
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? 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.
Ecology’s current work to address 6PPD and 6PPD-quinone (6PPDQ) is highlighted below. This update includes current agency actions. Contact us at 6PPD@ecy.wa.gov.
Momentum Builds for Solutions to Tire Wear Pollution: Last month, Ecology hosted a virtual 6PPD State of the Science Forum, connecting researchers, policy practitioners, and partners from across the globe to share knowledge and accelerate progress.
Since 2015, Puget Soundkeeper has monitored coho salmon health in Seattle’s Longfellow Creek, producing data on the impacts of urban pollution on salmon survival. For years, Longfellow Creek has been the epicenter of research studying the effects of 6PPD-quinone — a toxic tire chemical lethal to coho salmon.
According to a Puget Soundkeeper news release, exposure to 6PPD-quinone causes a condition called Urban Runoff Mortality Syndrome (URMS), a disease characterized by symptoms such as disorientation and gasping for air, often killing coho within 24 hours. Furthermore, this chemical has been strongly linked to Pre-Spawn Mortality (PSM), where adult salmon die before successfully reproducing, the news release said.
Puget Soundkeeper’s annual Pre-Spawn Mortality Surveyanalyzes the spawning success of coho salmon in Longfellow Creek to better understand the impacts of 6PPD-quinone. From October through December, trained volunteers count and dissect returning coho salmon, particularly assessing the presence of eggs and milt to determine whether spawning was successful.
Results from the 2025 study show that 55.5% of coho salmon died before spawning. This aligns with data collected since 2015, which shows that 49-90% of returning salmon die before reproducing each year.
“This level of pre-spawn mortality is devastating,” said Ewan Henderson, clean water program specialist at Puget Soundkeeper. “The dramatic reduction in successful spawning opportunities is a huge blow to our ecosystems, particularly for our resident orcas who already face major challenges as their food sources dwindle.”
According to the press release, Green Stormwater Infrastructure (GSI) projects, such as rain gardens or bioswales, can effectively remove toxins from runoff and prevent harmful chemicals from entering local waters. In addition to GSI projects, a bill (HB 2421) aimed at removing 6PPD from tires was introduced to the Washington State House and Senate Environment Committees last week.
Puget Soundkeeper will be recruiting the next cohort of salmon surveyors in August. More information will be made available on their website.
Councilmember Susan Paine, center, makes a point about the critical areas ordinance during a Q&A with staff Tuesday night.
Key takeaways:
Michelle Dotsch elected council president, Jenna Nand selected president pro tem.
Numerous residents testify in support of a measure they say would better protect the Deer Creek critical aquifer recharge area (CARA) — and council approves it 4-3.
Councilmembers sworn in and last year’s council president gets a sendoff.
Council votes to increase the city’s transportation impact fees.
We have a serious human health issue brewing in Edmonds at the Deer Creek CARA (Critical Aquifer Recharge Area), which provides drinking water to south Edmonds, Woodway, and Esperance. The issue is accommodating potential development instead of avoiding contaminating our drinking water with PFAS – a pervasive, forever chemical known to have serious human health effects.
Believe it or not, the City actually wants to allow new development to inject potentially toxic stormwater (containing forever chemicals, PFAS, carcinogenic pollutants, etc.) into the Deer Creek drinking water Aquifer.
On Oct. 16, a group of Edmonds-Woodway High School students with the Students Saving Salmon Club were performing routine water quality testing in Shellabarger Creek when they saw something disturbing: a young coho smolt swimming weakly on its side. On the shore nearby was another dead coho smolt.

EDMONDS — The Washington Department of Fish and Wildlife issued a new permit to the city of Edmonds on Friday, allowing flood-prevention work to commence at a controversial flow diversion structure on Perrinville Creek.

There’s a new development in the decades-long tug-of-war between the City of Edmonds, the State Department of Fish and Wildlife (DFW), environmental groups and adjacent property owners to balance flood control and fish passage on lower Perrinville Creek. The DFW has issued a limited temporary permit to allow the City of Edmonds to clear accumulated debris from the city’s existing sediment trap/overflow structures, with the aim of mitigating potential flooding during the upcoming rainy season. The permit expires on Jan. 13, 2026, and work must be completed by that time.
The Edmonds Waterfront Center welcomes Edward P. Kolodziej, internationally recognized environmental chemist and the Allan and Inger Osberg Professor at the University of Washington (Tacoma/Seattle) as the featured speaker in Annie Crawley’s Environmental Speaker Series. The event takes place at 6 p.m. on Thursday, Sept. 11, the latest installment in a community-based science and conservation initiative focused on Puget Sound.
