New Delhi, Jul 27 (PTI) A spike in ammonia levels in raw water discharged from Haryana hit water supply in parts of the national capital on Monday, Delhi Jal Board Vice Chairman Raghav Chadha said.
'Due to increase in pollutants (ammonia levels) in raw water discharged from Haryana, the water supply will be affected in parts of West Delhi, North Delhi, Central Delhi and South Delhi. We endeavour to restore normal water supply ASAP. Please use water judiciously,” Chadha posted on Twitter.
On Friday, too, the DJB curtailed supply at Wazirabad, Chandrawal and Okhla water treatment plants due to high levels of pollutants in the Yamuna.
A DJB official said Haryana had opened the gates of drains that had stagnant water with a high pollutant concentration, following heavy rainfall.
Effluent from industrial units upstream of the Wazirabad barrage might also have increased the pollutant levels in the river, the official said.
An official from the Haryana Pollution Control Board (HPCB) said they discussed the matter with the Delhi Pollution Control Committee and sought to know 'what issues are they facing'. 'Joint teams of the HPCB and the state's irrigation department have been deployed to take samples from crucial inspection points along the river and drains in Sonipat and Panipat districts to check water quality,' he said.
Meanwhile, the NGT-appointed Yamuna Monitoring Committee (YMC) has also sought a report from the Central Pollution Control Board (CPCB), Delhi Pollution Control Committee (DPCC) and industries commissioner on the reasons behind a 'sudden froth' in the river.
The two-member committee, comprising retired National Green Tribunal expert-member B S Sajawan and former Delhi chief secretary Shailaja Chandra, has asked the CPCB, DPCC Chairman Sanjeev Khirwar and Industries Commissioner Vikas Anand to take prompt action to detect the source of the froth in the river and act against those responsible.
The panel has asked the anti-pollution bodies to keep it informed of the matter.
In November last year, the YMC had asked the CPCB, DPCC and industries commissioner to take necessary action to close down the industries causing such environmental hazards.
The directions had come after 'shocking pictures of froth in the river got extensive media coverage' and 'very damaging comments' on the toxicity in the river during the Chhath festival.
The CPCB, in its report, had said a high phosphate concentration, mostly from household waste water, was the major reason behind frothing in the Yamuna. PTI GVS SMN SMN
