Water Quality Test Results
The Thornapple River SAD Committee will be conducting yearly testing on the Thornapple River to see their progress and guide the following year's river treatments. Test results will be published on this page each year, upon receipt of results from the contractors completing the testing and treatment. The
Water Quality Measurment Scale Explanation describes the purpose of each test, the normal range for results, and how residents are affected if the measures are outside of the preferred range.
