NPDES (National Pollutant Discharge Elimination System)

The National Pollutant Discharge Elimination System (NPDES) is a U.S. government program that regulates how industrial facilities, farms, and municipalities discharge pollutants into waterways like rivers, lakes, and streams. Its goal is to protect water quality by setting limits on pollutants and requiring permits for discharges. Facilities must monitor and report their discharges to ensure they do not harm the environment or public health. Essentially, NPDES helps control pollution entering water bodies, promoting cleaner and healthier water resources for everyone.
