Dissolved oxygen (DO) The term 'Dissolved oxygen (DO) ' as it applies to the area of agriculture can be defined as ' The oxygen freely available in water, vital to fish and other aquatic life and necessary for the prevention of odors in water. DO levels are a critical indicator of a waterbody’s ability to support desirable aquatic life. Secondary and advanced wastewater treatments are generally designed to ensure adequate DO in waste-receiving waters by removing, digesting, or oxidizing oxygen-demanding wastes (see biological oxygen demand)'.
