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.

  • 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
