Conventional Pollutants

Conventional pollutants are typically those that are the original focus of water pollution control efforts and do not include toxic substances. Examples include bacteria, chlorides, and nutrients.

While dissolved oxygen is not a pollutant, elevated levels of bacteria, chlorides, and nutrients can have a negative effect on dissolved oxygen (DO). Adequate levels of DO are necessary for a functional, healthy ecosystem, and the DRBC has established water quality criteria and monitors DO levels in the Delaware River.
