CPCB Analysis Claims Yamuna Water Quality Getting ‘Critically Serious’

Share on:

The water quality of the Yamuna river in Delhi was found to be declining due to pollution, according to a recent analysis by the Central Pollution Control Board. The water quality was termed as ‘critically worse’ by the board.

The data collected by the board stated that out of the fourteen monitoring locations set across the river in the city, only two met the criteria of moderate quality. The rest failed to meet the various parameters in the past five years. The analysis was submitted to the National Green Tribunal by the monitoring committee of CPCB.

Suggestions from the CPCB include, “Improvement in the Yamuna’s water quality at Delhi will require stoppage of sewage and industrial waste water discharged, from both Haryana — about 500 million litres per day (MLD) from several townships — and UP — 65 MLD at Ghaziabad. Besides, the flow of sewage through Najafgarh and Shahdara drains… and all other drains in Delhi has to be trapped.”

Numerous studies have stated that water quality has degraded in recent years and the same needs to be treated as soon as possible. The river is a major source for water consumption by residents of Delhi and the NCR region. It was found that more than 22 drainage pipes discharge untreated sewage into the river.

The report states that the length of pollution of the river has increased to 600kms from the previous statistic of 500kms. More than 1500 crore has allegedly been spent by the centre to clean up the river but the CPCB claims to be of no use. Ammonia and Coliform bacteria are found to be the major pollutants in the river.
