Question

Conclusion for water pollution

Answer 1

The water in most of our rivers is highly polluted.The pollution of river water is caused by the dumping of untreated sewage and industrial wastes into it.for example,the river ganga which flows for over 2500 kilometers from gangotri in the Himalayas to ganga Sagar in the bay of Bengal is being turned into a dirty water drain by the discharge of untreated sewage and industrial wastes emanating from more than a hundred towns and cities which lie along it's way.

The contamination of water can be usually found from two factors:

1-- the presence of caliform bacteria in river water,and

2-- measurement of pH of river water.

Wells and tube-wells( bore- Wells) are yet another source of water..
