Water is also present in the atmosphere in solid form in the polar icecaps and as groundwater in aquifers water-bearing rocks deep underground.
Water has many remarkable properties. It also acts as a fluid medium facilitating the dispersal of un-dissolved particulate matter.
Water pollution may be defined as any chemical or physical change in water detrimental to living organisms. It can occur through natural processes, for example by sediments produced by natural erosion.
Water bodies are a major recipient of an extensive array of wastes produced by human activity. These may be discharged directly into watercourses by sewers or pipes from factories or be washed down from agricultural or urban areas particularly after heavy rains.
Under rather exceptional circumstances, water bodies may become significantly contaminated by the atmospheric deposition of pollutants. Water pollution is a global problem and one that does not respect national boundaries. Sources of pollution may be domestic, agricultural or industrial. In less-developed countries, human and animal waste and sediments from unsound agricultural and forestry practices are the main pollutants.
In more-developed countries; industrial pollutants, such as toxic metals, organic Chemicals and heat add to the water pollution problem. The effectiveness of treating wastes prior to their release into the environment determines the balance between potential and actual pollution.
Organic oxygen-demanding wastes The release of large quantities of oxygen-demanding organic waste into watercourses often has disastrous effects on the indigenous flora and fauna. The primary source of organic waste released into fresh waters is sewage effluent.
Other sources include run-off from urban areas and farms, and some industrial effluents.
The recent intensification of livestock production, with larger herds concentrated in smaller areas, has exacerbated the problem of organic pollution from farm animal wastes.
Plant nutrients Aquatic primary productivity is often limited by the availability of inorganic plant nutrients. In freshwater lakes and rivers, the limiting nutrient element is usually phosphorus, whilst in marine waters nitrogen is often in short supply.
If small amounts of nutrients enter aquatic ecosystems where they are normally limiting, primary productivity is stimulated. The water body becomes over-enriched by excessive nutrient input and consequently polluted.
Acidification Both acid rain and acid mine drainage contribute significantly to the acidification of natural waters. These two phenomena are dealt with in detail in this section.
However, there are other causes of this particular type of water pollution. For example, the planting of extensive tracts of coniferous forests, usually in upland areas, results in the acidification of the soil and the waters which drain these plantations.
Organochlorines Organochlorines are, as name suggests, organic compounds containing chlorine. Manufactured organochlorines include a number of pesticides, for example DDT, and polychlorinated biphenyls, or PCBs as they are known. These two groups will be considered separately, although they do share a number of important characteristics.
For example, both groups are reported to have endocrine-disrupting properties.Water pollution is the contamination of water bodies, usually as a result of human activities.

Water pollution is the introduction into fresh or ocean waters of chemical, physical, or biological material that degrades the quality of the water and affects the organisms living in it.
3/5(10). The Status of Water Pollution in Canada Water pollution in Canada as well as many parts of the world is becoming more of an issue as more waste leaches into water systems.

Pollution is the process of making land, water, air or other parts of the environment dirty and unsafe or unsuitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn't need to be tangible.
