Answer 1

Answer:

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 kilometres 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 its way.

In addition to sewage and industrial wastes, the pollution of river Ganga is also caused by other human activities like bathing, washing of clothes, immersion of ashes of the dead and dumping of unburnt corpses in its water. The industries also discharge chemical effluents into the river water. The toxicity of these chemical effluents kills the fish in many parts of the river.

The contamination of river water can be usually found from two factors: (i) the presence of coliform bacteria in river water, and (ii) measurement of pH of river water. Coliform is a group of bacteria found in human intestines. The presence of coliform in the river water indicates its contamination by disease-causing micro-organisms.
