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.
Pollution that comes from a single source like an oil or chemical spill is known as point source pollution. Often this type of pollution has large impacts but fortunately they occur less often. Discharge from faulty or damaged factories or water treatment systems is also considered point source pollution.
