Water pollution is a major environmental issue in India. The largest source of water pollution in India is untreated sewage.Other sources of pollution include agricultural run off and unregulated small scale industry. Most rivers, lakes and surface water in India are polluted.

A 1992 World Health Organization study reported that out of India's 3,119 towns and cities, just 209 have partial sewage treatment facilities, and only 8 have full wastewater treatment facilities. Downstream, the river water polluted by the untreated water is used for drinking, bathing, and washing. A 1995 report claimed 114 Indian cities were dumping untreated sewage and partially cremated bodies directly into the Ganges River. Lack of toilets and sanitation facilities causes open defecation in rural and urban pill areas of India, like many developing countries. This is a source of surface water pollution.

Case Study :

In recent days i visit the Madhya Pradesh region In India there is a district named as Dindory, the water is very polluted and full of arsenic and mercury. When i taste the water it seems like a crystalline solution of alum. The people reside in the region either they are restrain or they have no option for drinking water. After some time i was assumed that the water is polluted due to mountain and rivers region. The children are daily uses this water for drinking and they use river water for bathing and sanitation. 

How to control water pollution :

Recycling, Renovation, Recharge and Reuse (4R concept) of waste water:

The waste water consisting of domestic sewage industrial effluents, thermal and radioactive pollutants receive some sort of treatment before mixing into water bodies. Urban sewage and sludge etc may be recycled and reused to generate cheaper fuel, gas and electricity.

Household Items

Do not throw household items, such as cloths, dental floss or wrappers, into the toilet when you are done with them. Toilet paper is specifically made in a way that breaks down easily in water pipes, but these other items pollute the system.

Limit the Use of Detergents and Bleaches

While it is okay to use detergents and bleaches in dishwashers and washing machines, it is better to limit your use as much as possible. Do not put two cups of bleach in your washing machine when the instructions only call for half a cup.

Use Environmentally Friendly Detergents

Whenever possible, get environmentally friendly detergents, soaps and dish washing liquids. While these are sometimes more expensive, you are doing the environment a great service by using less harmful substances.

Gardening

While everyone wants a nice garden in their home, it is incredible how much water we waste during that process. Install a water butt in your home, because it can catch rainfall throughout the year and allow you to use that to water your grass and plants.
