Hey here is Your answer Friend,

1. Human dumping: Due to human dumping of waste and other harmful substances in to river water directly. Since most of the towns and cities are beside rivers, the human waste is

2. Industrial waste release: Most industries release their processing waste into the rivers. This is an easy methods for them to get rid of waste. But by release of industrial sewage into river water there is severe pollution to the water.

3. Land water flow: Contamination during rains due to the flow of rainwater from contaminated land into rivers. In case of floods where water from river flows over surrounding lands. This flow collects all the possible waste and dump into river.

4. Air pollution: The air pollution is formed by disposal of harmful gases into air. This pollution from air in-turn returns to ground through rains and contaminate groundwater and river waters. This indicates that the pollution we create finally reaches us in one or other way.

5. Farm pollution: Farming is the industry which relies heavily on river water. The river water is used for irrigation. But pesticides and other toxic chemicals are used by farmers to control diseases. These toxins reach the river canals which supply water the cities and towns ahead.

6. Improper Drainage system: Drainage system pollution, this is the form of water pollution where sewage and regular public water supply mix up. This is seen primarily in cities where water is pumped from distant out places. This occurs when there is leakage of sewage water and mixing with that of pure water supplied by municipal water pipes.


7. Groundwater contamination: Water on the land is absorbed by the soil. Along with water any chemicals or toxin on the land are also absorbed. This happens at places of heavy land pollution. These harmful substances on the land percolate into deep ground layers causing pollution. Thus there are many cases where groundwater from bore-well was found to be harmful.

8. Plastic waste: Plastic is another threat adding to marine water pollution. Plastic pollution occurs due to accumulation of plastic waste for long in the seas beds as it is not decomposed fast. It is thought to be responsible for destruction of aquatic environment.

9. Due to fisheries: Fisheries is a part of agriculture but mainly depend on rivers. Many chemicals and drugs are used to enhance fish growth. But since these are collected with rivers. All the waste is flowed out into rivers.

10. Due to leakage of petroleum and other oils from vehicles etc on to the local roads. Even from mechanic sheds this is released. These petroleum wastes are mixed with ground and other water sources.

PReventive methods!!

1) Avoidance of dumping of human waste directly into the river water. This has to be taken as an individual responsibility by all.

2) Proper treatment of waste by industries before releasing into rivers. The waste must be detoxified and rendered harmless. The enactment of strict rules and laws can help prevent this pollution.

3) Purification of water before using for cooking, drinking and other domestic purposes.

4) Maintenance of proper river banks and repair them when damaged.

Water is a part of our environment. If it is contaminated the whole of life on earth will be in trouble. Since humans are the sole reason for this water pollution, it is we who should care to reduce this pollution.
