Water Pollution

Water pollution is one good example of water damge. Generally, when water becomes unsafe either for consumption or use or it becomes uncontrollable, in cases of flooding, we have an occurrence of water damage. A prevalent from of water damge is when water becomes unsafe for drnking orother bodilu usage. This is often caused by several form of pollutants that a water comes in contact with. These pollutants affect the quality and potential use of the water. In this article, we would be looking at water pollution as a whole.

Water is polluted by what is called pollutants. These pollutants come from two basic sources. These sources are point sources or dispersed sources. A point-source pollutant is comes from a single channel such as pipeline, sewage discharge or outfall pipe. While broad, unconfined areas from which pollutants enter a body of water are referred to as the dispersed sources. Examples of dispersed sources include surface runoff from farms, carrying animal wastes, fertilizers, pesticides, and silt into nearby streams are also good examples of dispersed source of pollution. There are different ways that water gets polluted and become unsafe for human consumption. The various ways pollution can occur to a water can be both natural or as a result of man’s exploration activities of nature. For example, a water can gwt polluted naturally through urban storm water drainage, when an urban strom water drainage occurs, it carries sand and other gritty materials into a whole body of water such as the river or stream which makes the body of water get polluted. Such form of water population however, can still be treated easily, but pollution from man’s exploration of his physical environment such as petroleum residues from automobiles, and road deicing chemicals, can also be reffered to as disperse source of pollutant cause heavy pollution and irreversible change to the water affected. Petroleum residues from automobiles, and road deicing chemicals are disperse source of pollutant because there are many points of penetration by which it bodies of water such as the stream or lake. In the control method and curative methods of these water pollutants, point-source pollutants are much easier to control than the dispersed-source pollutants. This is because point-source pollutant flow to only one location where treatment processes can easily remove them from the water. However in the case of disperse sources, such control might not be feasible. A large part of the overall water pollution is mainly caused by the disperse-source pollutants. The only best way to control dispersed-source water pollution is by enforcing proper land-use plans and development standards.

There are other types of water pollution aside the two major types discussed earlier. General ways in which can be polluted include pathogenic organisms, oxygen-demanding wastes, plant nutrients, synthetic organic chemicals, inorganic chemicals, sediments, radioactive substances, oil, and heat. Farms and industrial wastes are also contributors to general water pollutants. Sediment from eroded topsoil can also be regarded as a pollutant because of the damage it can cause to aquatic ecosystem. Heat generated from power-plant cooling water can also be considered a pollutant it has an adverse effect on aquatic life in water bodies (rivers, streams and lakes).
