Polluted Runoff (NPS) Information

Polluted runoff or Nonpoint Source (NPS) pollution is caused by rainfall or snowmelt moving over and through the ground picking up pollutants along its journey to lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water. Some of these pollutants are natural and others are man-made. With your help, we work toward reducing these pollutants in our waterways.
