National Pollutant Discharge Elimination System

The National Pollutant Discharge Elimination System (NPDES) is a program that regulates how industrial facilities, wastewater treatment plants, and other sources release pollutants into rivers, lakes, and streams. Its goal is to protect water quality and public health by setting limits on the amount and types of pollutants that can be discharged. Facilities must obtain permits and follow specific treatment and monitoring requirements to prevent contamination and environmental harm. Essentially, NPDES helps ensure that water pollution is controlled and kept at safe levels for ecosystems and communities.
