There are two main types of pollution, point source pollution and nonpoint source pollution. Point source pollution comes from one source (you can easily point to it) like a factory or waste water treatment plant.
Geology, geomorphology, and climate also influence water quality. Pollution can be defined as the fouling or making unclean of air or water to the point where beneficial uses are harmed. Water pollution is generally characterized as originating from either point or non-point sources. Point source pollution is associated with a particular site on a stream and typically involves a known quantity and type of pollutant that can be controlled at the site. An example of point source pollution is effluent from a factory outlet (an end-of-pipe discharge) delivered directly to a stream.
