Non-Point Source (NPS) Pollution
Non-point source pollution results from the accumulation of pollutants over a broad area that are transported to receiving waters by stormwater runoff. The pollutants come from 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 bare soils
- Toxins - airborne chemicals, oils, and metals
