National Pollution Discharge Elimination System (NPDES)

The National Pollution Discharge Elimination System (NPDES) is a U.S. federal program that regulates the release of pollutants into waterways. Established under the Clean Water Act, it requires industries, municipalities, and other entities to obtain permits before discharging wastewater. These permits set specific limits on pollutants and require monitoring to protect water quality. The NPDES aims to reduce water pollution and safeguard public health and the environment, ensuring that the country's rivers, lakes, and streams remain clean and safe for recreation and wildlife.
