What Does Water Testing Tell Us about Water Quality?

Students test water from multiple locations on the Potomac River for dissolved oxygen, nitrates, phosphates, pH levels, salinity, and turbidity. What do these tests tell us about the health of the river? Related videos on land use and species diversity allow us to look at the river through different lenses. Students may want to access documents linked on this page for more information about the water tests and Chesapeake Bay watershed.
