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.
Pollution is unwanted, harmful stuff contaminating an environment. The race to develop clean energy is motivated by high levels of pollution that people fear are permanently damaging the earth's environment. When you hear about pollution, youâre most likely hearing about chemical emissions into air or water that come from industrial processing. But pollution isnât just environmental. Anything we think of as pure can be contaminated by pollution polluted, whether that's a lake or an idea.
