When assessing the overall health of a stream there are many different variables that need to be considered and monitored. There are countless factors that can influence the health of a body of water; ranging from activities occurring directly in or next to the water body, to activities that occur throughout the watershed. NCDEQ’s ambient water quality monitoring program collects a wide range of data including temperature, specific conductance, turbidity, total suspended solids, dissolved oxygen, pH, fecal coliform, nutrients, total hardness, chloride, fluoride, sulfate, oil and grease, and dissolved metals. Additional water quality monitoring includes the municipal ambient water quality monitoring programs for illicit discharge detection and elimination, and special studies being performed by others in the watershed. We are dedicated to using water quality data that has been collected in a manner that is consistent with the prescribed quality control and assurance procedures. By doing so, this allows us to be confident in our knowledge of the health and quality of our streams.
