Although many and varied, all sources of water pollution are classified as either point or nonpoint. Pollution comes from a point source if its origins are distinct and identifiable; hence, point source is also called an end-of-the-pipe source. Pollution from point sources can usually be quantified, often by direct measurement. Point sources can often be regulated effectively with federal and state permits.
