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 Manual

This manual includes all the details you’ll need for water quality monitoring (including which bottles to use for sampling, directions for collecting your samples and running the tests, data sheets, site surveys, optimal values and much much, more!)  It’s a big document, so we separated it into sections to make downloading easier:

Section I:  Preparing for Monitoring

Section II:  Tools for Monitoring Day

Section III:  Understanding Your Monitoring Results

Section IV:  Appendix

Section V:  The Mulitiple Intelligences Table

South Sound GREEN Water Quality Monitoring Sites

Each year over forty sites are monitored by about thirty different classrooms around Thurston county.

Water Quality Data

Students in the South Sound GREEN program have collected data on South Sound streams since the mid-1990’s.  Please see below for current and past data:
