Stormwater is the number one source of toxic contamination in Puget Sound. Read more here.

Did you know...

The Salish Sea School is studying the types and amounts of contaminants flowing out of local outfalls directly into the Salish Sea.

We are sampling for:
Heavy Metals (Copper, Zinc, and Lead)
Diesel and Heavy Oils in Water
Total Suspended Solids (TSSS)


Example site below: The Anacortes Ferry terminal outfall we are testing can be seen circled in red, below. The other outfalls we are testing (in partnership with Friends of Skagit Beaches) are seen designated by the yellow arrows in the second image.

Local students also helped to create the outreach brochure seen below. This will be passed out to students/families at local high schools and in their communities. This brochure will inform families how they can help reduce the contaminants entering stormwater at their homes. Good work Alan and Aracely!
