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.
Water pollution is generally caused by human actives but may also be caused by natural resources. When water is polluted it is usually defined as either being polluted from point sources or non point sources. Point source pollution occurs from a specific location by a single source such as a large factory, oil refinery or hauling ship that contributed a massive amount of pollution within a single area.
