**Stay tuned for updates regarding Water Quality Monitoring for the 2023-2024 school year! If you are interested in participating for the first time, please reach out to Sam Nadell at email@example.com**
Within our popular Water Quality Monitoring program, Thurston County students and their teachers monitor water quality in their local streams or river twice annually, once in October and once in February. They use kits to test for dissolved oxygen, pH, nitrates and turbidity. Students measure both the air and water temperature and many classes collect sterile samples for bacterial analysis. Students at local high school filter these samples, incubate them and count the fecal coliform colonies after 24 hours. These water quality parameters are important for aquatic organisms and/or have implications for human health.

Water Quality Monitoring Curriculum Overview (6th-8th Grade)
*Curriculum overviews for other grade bands coming soon!*
Our Water Quality Manual has been updated for the 2023-2024 school year. Inside you will find a bit of history for each water quality testing program, some background information about each of the tests, updated instruction and data sheets, and additional activities to assist you on monitoring day!
WQ Presentation- SS GREEN Watersheds: This slide show highlights South Sound GREEN’s watersheds, how water is affected by point and non-point source pollution, and some details about the specific parameters we use to measure water quality.
To adapt to a virtual learning environment, we created a Water Quality Monitoring Story Map for students to experience water quality testing from home with historical data dating back to the 1990s. This includes overviews of all of the Water Quality Parameters we test for, as well as instructional videos on how to do each of the WQ tests. Watch our Story Map Overview to understand how to best use the resource!

Water Quality Monitoring Videos
In 2020 we worked with our friends at the Nisqually River Education Project to create a series of videos to introduce students to Water Quality Monitoring. You can find all four videos (Watershed Overview, Introduction to Water Quality, Water Quality Parameters, and Influences on Water Quality) in this shared Google Drive folder.
