We drink it, cook our food with it, bathe in it, and wash our body and things with it. The farmers need water for growing crops or plants. With water, the soil becomes wet.

Then it becomes fit for sowing seeds there, the new plants can grow well only in the wet soil. The water comes from the rain. If not, the soil is then made wet by irrigation or otherwise. Pure water should be used for drinking.

Impure water carries germs and spreads diseases. Impure water can be purified by distillation or filtration process. Man cannot live without water.

Our earth is covered with water (almost 70% of total) so a little change in it could affect lives worldwide.

The highest level of water pollution is caused by the pollutants come from agriculture field because of the high use of fertilizers, insecticides, and pesticides to enhance the production of crops.

Other hydrocarbon particles get settled down through rain water from air to ocean or sea water. Other toxic wastes through leakage of landfills, old mines, dumps, sewage, industrial wastes, and farms get mixed to the water.

The level of fresh drinking water is becoming less day by day on the earth. There is a limited availability of drinking water on the earth however that too is getting polluted because of human activities. It is tough to estimate the possibility of life on the earth in the absence of fresh drinking water. Water pollution is the mixing of foreign substances by means of organic, inorganic, biological and radiological in the water degrading the quality and usefulness of water.

Hazardous pollutants may contain various types of impurities including harmful chemicals, dissolved gases, suspended matters, dissolved minerals, and even microbes.

However biochemical oxygen is the demanded oxygen by the aerobic micro-organisms to oxidize organic matters of wastes. Water pollution is caused by two means, one is natural water pollution (due to the leaching of rocks, decay of organic matters, decay of dead matters, silting, soil erosion, etc) and another one is man-made water pollution (due to the deforestation, set up of industries near large water bodies, high level emission of industrial wastes, domestic sewage, synthetic chemicals, radio-active wastes, fertilizers, insecticides, pesticides etc).

Fresh water is the most important source of life on the earth. Any living thing may survive without food for days however it is impossible to imagine life without water and oxygen. The ever increasing human population enhances the demand of more water for purposes like drinking, washing, performing industrial processes, irrigating crops, arranging swimming pools and other water-sports centres.

It makes possible the possibility of any forms of life here and their existence. It maintains the ecological balance in the biosphere. Clean water is very necessary for fulfilling the purpose of drinking, bathing, washing, power generation, irrigation of crops, disposal of sewage, manufacturing processes and many more. Increasing human population causes rapid industrialization and unplanned urbanization which are releasing lots wastes into the small and large water bodies which ultimately degrades the quality of water. The mixing of such pollutants directly and continuously into the water bodies decreases the self purifying capacity of the water by declining the ozone (which kills harmful microorganisms) available in the water.

Contamination of water deteriorates the chemical, physical, and biological characteristics of the water which is very harmful to the human beings, animals and plants all over the world.

There are many sources of the water pollution (point source and nonpoint or diffused source) depending on the specificity of waste materials discharged from various sources. Point sources includes pipelines, ditches, sewers, etc from industries, sewage treatment plants, landfills, hazardous waste sites, leakage from oil storage tanks which discharges wastes directly into the water bodies. Diffused sources of the water pollution are agricultural fields, live-stock feed lots, parking lot and streets into surface water, storm runoff from urban streets, etc which pours their discharged pollutants over the larger areas water bodies. Non-point source pollution contributes highly to the water pollution which is very difficult and expensive to control.

People generally used to take early morning bath and use Ganga Jal as an offering to the God and Goddess during any festival and fast occasion. They also discharge all the wastes of puja ceremony in the Ganga in the myth of completing their puja.

Discharging of wastes in the rivers causes water pollution by decreasing the self recycling capacity of the water so it should be banned by the government in all countries especially India in order to keep the river water clean and fresh. The condition of water pollution is much worse in the India than other countries having high level of industrialization.
