what are two examples of nonpoint pollution
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.Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a non-point source of pollution.on-point source pollution can be contrasted with point source pollution, where discharges occur to a body of water or into the atmosphere at a single location.
