This project is funded through a Public Participation Grant from the Washington State Department of Ecology. The content was reviewed for grant consistency but is not necessarily endorsed by the agency.​

The Salish Sea School is studying the types and amounts of contaminants flowing out of local outfalls on (or near) Fidalgo Island, Washington.

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


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.

Two students (Aracely Cortes-Garcia and Alan Santiago) are helping to record rain amounts seen here and contaminant data seen here. These same students will also be helping with an outreach brochure to pass out to students/families at local high schools. They will be translating this information into both English and Spanish. This brochure will inform families how they can help reduce the contaminants entering stormwater at their homes. Good work Alan and Aracely!
