Explanation: Point sources are for example,
water discharging from an industrial plant of
some kind or a waste water treatment plant. Non-point sources include run-off from agricultural lands that may wash fertilizer or other chemicals into lakes or rivers – this may occur over thousands of square kilometres.
What are 3 examples that are considered point source pollution?
- Industrial plants/factories (e.g., oil refineries, pulp and paper mills, chemical manufacturers, automobile manufacturers, food processors, pharmaceutical manufacturers) Pollutants: oil, thermal pollution, toxic chemicals, heavy metals, pharmaceuticals.

What are some examples of point source and nonpoint source pollution?
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example,
