Water Pollution

 

Water is essential for life. Without water life would have been impossible. The slogan, ‘Save Water, Water will save you’ tell us the importance of water. Such slogans tell us to save water. Apart from saving water, maintaining its quality is also equally important.


Now a days water is getting polluted due to human activities and the availability of potable water in nature is becoming rare day by day.Water pollution is defined as“The addition of foreign substances or factors like heat which degrades the quality of water, so that it becomes health hazard or unfit to use.”

The water pollutants originate from both natural and human activities. The source of water pollution is classified as Point and Non-point source.

Easily identified source of place of pollution is called as point source. Example: municipal and industrial discharge pipes.

Non- point source cannot be identified easily, example: agricultural runoff, mining wastes, acid rain, and storm-water drainage and construction sediments.
