The main water pollutants are:
- Sewage and other oxygen demanding wastes (mostly organic matter, whose decomposition produces oxygen depletion).
- Infectious agents.
- Plant nutrients that can stimulate the growth of aquatic plants. These, in turn, interfere with the uses to which water is intended and, when decaying, deplete dissolved oxygen and produce unpleasant odors.
- Chemicals, including pesticides, various industrial products, surface-active substances contained in detergents, and products of the decomposition of other organic compounds.
- Petroleum, especially from accidental discharges.
- Minerals and inorganic chemicals.
- Sediments consisting of soil and mineral particles carried by the storms and runoff from farmland, unprotected soils, mining, roads and urban demolition.
- Radioactive substances from the waste produced by mining and refining of uranium and thorium, nuclear power plants and industrial use, medical and radioactive materials scientist.
