What are the causes of rapid water pollution in rivers and other water bodies? What schemes and measures have been taken to prevent it?

The causes of rapid water pollution in rivers and other water bodies are as follows :

  1. Water in rivers and lakes is being reduced as the requirements of rapid urbanisation, population growth and industrialisation cause more water to be drained out from them.
  2. Huge amounts of untreated sewage and industrial effluents are being emptied into the rivers and other water bodies.
  3. Human ashes (due to cremation near the water bodies), dead animals and leaching out of nitrogen compounds from fertilised agricultural lands also increase the pollution.

The schemes and measures that have been taken to reduce water pollution are as follows :

  1. The steering committee of the National River Conservation Authority reviewed the progress of the Ganga Action Plan (GAP) and necessary correction were made.
  2. These new method applied to the major polluted rivers of the country. The Ganga Action Plan (GAP) Phase-ll, merged with the NRCP.
  3. A total of 215 schemes of pollution abatement have been sanctioned of which 69 schemes have been completed under this action plan.
