Water Quality in Delhi-NCR Remains a Concern: Report Highlights High Pollution in Yamuna

76% of river water found unfit; groundwater depletion worsening crisis

A recent survey by the Central Pollution Control Board (CPCB) has revealed alarming levels of water pollution across Delhi-NCR. According to the report, nearly 76% of Yamuna’s water is classified as unfit for consumption, posing severe health and environmental risks.

 

The findings show that the biological oxygen demand (BOD) level in most stretches of the Yamuna remains between 11 to 15 milligrams per liter, far above the permissible limit, indicating high contamination. Experts warn that untreated sewage, industrial effluents, and solid waste continue to flow into the river despite repeated directives for cleanup.

 

The study also highlights the worsening groundwater crisis in NCR districts. Over-extraction for urban consumption and agriculture has pushed water levels to critical lows, leaving several areas dependent on tanker supply. In some regions, groundwater has dipped to as deep as 50 meters.

 

Environmentalists have urged immediate action, including stricter enforcement of waste treatment norms, expansion of sewage treatment plants, and public awareness drives to curb domestic pollution.

 

Authorities acknowledged the crisis and said that steps under the “Namami Gange” and “Jal Shakti Abhiyan” programs are being accelerated to restore water quality and recharge depleting aquifers.
