Non-point source (NPS) pollution refers to both water and air pollution from diffuse sources. Non-point source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Non-point source air pollution affects air quality from sources such as smokestacks or car tailpipes.
Water pollution is identified in two categories. Point Source Pollution is contamination that comes from a single, clearly identifiable source, such as a pipe which discharges material from a factory into a lake, stream, river, bay or other body of water.Point source pollution is relatively easy to identify. Non-point Source Pollution is more difficult to identify.ater pollution is identified in two categories.
