Water Quality Monitoring

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.
