Clean water act-is essential to human health, productive economies, and robust ecosystems. The CWA is a comprehensive and technically rigorous piece of legislation that seeks to protect the nations navigable water ways from pollutions.PA created the concept of a mixing zone to allow a discharge to disseminate and become diluted prior to water quality testing. A mixing zone is the distance extending 100 meters in all directions from the effluent discharge point.
Factors Affecting Water and Sediment Quality: Pollution. Pollutants can be released into the environment as gases, liquids, dissolved substances, or particulates, and can enter aquatic ecosystems by atmospheric deposition, soil erosion, seepage, runoff, or direct discharge. Pollution that can be attributed to a single source, such as a sewage outfall, is known as point source pollution. Pollution that originates from diffuse sources rather than from one discrete locationâfor example, runoff that carries pesticides into the water from agricultural fieldsâis known as non-point source pollution. Pollution can be released into the environment with different frequencies.
