Explanation:

In India, river pollution has crossed the mark of crisis. Three important river systems of the north like Indus, Ganga and Brahmaputra are suffering from pollution .  Fresh water is only 2.7 per cent out of total water available in nature. The remaining 97.3 per cent is saline water. Out of the total fresh water (2.7%), 0.003 per cent water exists in rivers, whose total volume is 108 cubic km while the volume of water existing in lakes is 1, 26,070 cubic km. Thus, the water deposit in lakes is more than the water deposit in rivers.River water is used to a maximum extent because of its common reach to the biotic community. Maximum economic activities concentrate around rivers. At present, 50 per cent population of the world resides in 250 river basins, where they use river water for different activities including agriculture and industry. In India, dense population is settled near the banks of rivers Ganga, Yamuna, Damodar, Hooghly, Cauvery, Godavari and Chambal. This has polluted these rivers to a large extent. Rhine river of Europe, literal meaning of which is pure (Rhine=Pure), is polluted to a great extent.In India, river pollution has crossed the mark of crisis. Three important river systems of the north like Indus, Ganga and Brahmaputra are suffering from pollution. Maximum populated areas of the world are settled in all the three basins. These river systems originating from snow peaks of Himalayas are the basis of prosperity of India in different forms.In southern India, river Godavari, Cauvery, Krishna and Mahanadi are highly polluted. Rivers of India are no more rivers but have been converted into filthy drains. The Comptroller and Auditor General (GAG) of India has entrusted the responsibility of examination of quality of water to the Environ­mental Research Laboratory (ERL), Lucknow.
