Point source pollution http://en.wikipedia.org/wiki/Point_source_pollution From Wikipedia, the free encyclopedia A point source of pollution is a single identifiable source of air, water, thermal, noiseor light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries.
