Non-point source pollution is the accumulation of pollutants over a broad area that are released into the water by runoff. The pollutants are created by a variety of diffuse sources and activities that occur over the land, rather than at a single, identifiable location.
Types of NPS pollutants include:
Nutrients - Fertilizer and pesticides from lawns or farms
Organic wastes - From manure and sewage
Pathogens - Bacteria and viruses
Salt - From irrigation and acid-mine drainage
Sediment - From erosion of unprotected lands
Toxins - Airborne chemicals, oils, and metals
