Water is one of the most important elements of our environment. It is next to air. Water pollution means contamination of surface and drinking water that makes the water harmful to use.

Water is polluted in various ways. Farmers use chemical fertilizers in their fields to get better crops. Again they use insecticides to kill harmful insects that damage crops. These elements are washed away into rivers, canals and ponds. They get mixed with water and pollute it. Sometimes mills and factories throw their waste products containing poisonous chemicals into rivers, canals and ponds and thus pollute water. Leaking of oil from water vehicles, dead bodies, and rotten debrises of animals and plants, germs of diseases and insanitary latrines are other factors that pollute water. As a result, all the species living in water will no longer be in existence. So, it is high time we stopped water pollution.

To fight against the pollution of water, sewage treatment plants must be built. We must not allow any kind of poisonous chemicals and wastes to get mixed with water so that it can be kept clean and pure. Above all, laws should be made and properly executed for dumping of industrial waste. It is time to find out the right way to control water pollution.
