SC seeks status report on river water quality:


Context:

The Supreme Court has sought a status report from the National Green Tribunal-appointed River Yamuna Monitoring Committee about its recommendations to improve the quality of water and the extent to which the States have implemented their suggestions.

  • The Committee was led by former Delhi Chief Secretary Shailaja Chandra.

Background:

The Supreme Court had, on January 13, taken suo motu cognisance of the contamination of rivers by sewage effluents through lapses committed by municipalities, saying “open surface water resources including rivers are the lifeline of human civilisation”.

Why is Yamuna so polluted?

  1. The sewage treatment plants of Delhi are major contributors of the Pollutants being discharged in the river.
  2. Pollutants discharge from different types of industry is also a major issue.
  3. Agriculture activities along the banks of the river in Delhi contributes to river pollution.
  4. Agricultural waste and pesticide discharge from the Haryana field also contributes to the pollution.
  5. The low volume of water flow in the river causes the pollutants to accumulate and raise the pollution level.
