A new air sensor is live in South Seattle! Our monitoring team recently installed a "SensWA" sensor, which measures fine particulate matter (PM2.5), at the Duwamish River Community Hub in South Park. Check out data from the new sensor: airqualitymap.ecology.wa.gov/site-info/543

There are about 6,500 contaminated sites in WA that need cleanup or are being cleaned up. Rating these sites gives us a better idea of the contamination and can help direct our work. Learn more about cleanup sites in your community on our new SHARP dashboard: ecology.wa.gov/blog/februar...

See ya later, pollution. 👋 Hello, cleaner water. 😎
Communities across Washington are preparing to improve wastewater facilities, install stormwater treatment, and fund new septic systems, thanks to $156.8 million in grants and loans from Ecology.

Did you know that WA has 3,026 miles of coastal shoreline? Our Coastal Zone Management Program has been protecting the state’s coastal beaches, habitats, and communities for 50 years. We are celebrating this awesome milestone for our work: ecology.wa.gov/blog/january...

For snowpack, we are sitting at 53% of normal statewide—but averages can be deceiving. In the N Cascades it varies between 26% at Beaver Pass and 109% at Rainy Pass.
We've had 115% of normal precipitation so far this water year, but lot of that has been rain. We need snowpack to get out of drought.

Let’s check in on our water supply: a thread 🧵
It looks like WA has been participating in “dry January” this year. The last 30 days have been dry across most of the state. On top of that, the past week has been warmer than normal in the Cascades and Olympics, which isn’t helping our snowpack.

Baby steps! The Cascades saw a lot more snow this week – enough to wash out the red on the NRCS basin snowpack map. We need consistent snowstorms to catch up to normal, and need that snowpack to hold on through spring to avoid drought this summer. But we’re slowly moving in the right direction ❄️

Today is World Ocean Acidification Day of Action 🌊 When we burn fossil fuels like coal, oil, and gas, excess carbon dioxide gets produced. As the ocean absorbs that carbon dioxide from the atmosphere, our waters become more corrosive, threatening coastal economies and ways of life.

Did record rainfall end Washington’s drought? Unfortunately, no. We got rain when we really needed snow, leaving snowpack at about 31% of normal. We'll need winter weather ahead to build up our "snow bank". Read more about what this means for our water supply in WA: ecology.wa.gov/blog/january...

In 2023, we eliminated 2M tons of greenhouse gases – that’s like taking 450,000 cars off the road 🚗 The program also reduces harmful air pollution & drives local investment. And our next rulemaking will boost clean fuel production through 2038! Learn more: ecology.wa.gov/about-us/who...

Can you guess what December’s Critter of the Month is? It’s a decorator crab on a decorated lab, of course! 🦀 Self-decoration camouflage is a defense strategy that allows the crabs to blend into the backdrop of their ecosystem to avoid predators.

More air quality data on the way! We’re planning a one-year mobile monitoring study to collect detailed air pollution data in overburdened communities and participating Tribal communities.
Stay tuned for more info about the routes, how we handle the data, and vehicle capabilities in late 2026.

Today we saw light sheening near Richland. We placed absorbent materials to capture oil upriver and around several water intakes in the Tri-City area. No reports of oiled wildlife. Over the next few days, please stay out of the water between the dam and Pasco while we continue cleanup.
