NGT directs Centre to state E-flow level of Ganga
The National Green Tribunal on Monday asked the Centre to clarify what should be the minimum environmental flow (E-flow) in the Ganga, in a bid to ensure uninterrupted water supply in the river.
The apex environment watchdog also said that unless the excessive extraction of water and discharge of high pollutants are controlled, it would be difficult to restore Ganga to its original pristine condition.
The E-flow defines the quantity, timing and quality of water flow required to sustain freshwater and the estuarine ecosystems, besides human livelihood.
A bench headed by NGT Chairperson Justice Swatanter Kumar directed the Environment Ministry, Ministry of Water Resources and the Central Pollution Control Board to provide complete information on e-flow to be maintained in the river.
It asked them to apprise the green panel about extraction of groundwater in the stretch of 543 km between Haridwar and Unnao, and state whether the water being diverted into the various canals should be regulated so as to help maintenance of minimum flow of the river.
"Ministry of Environment and Forests, Ministry of Water Resources and CPCB will take a clear stand as to what should be the minimum environmental flow of river Ganga in Segment-B (Haridwar and Unnao)," the bench said. The NGT fixed the matter for hearing on April 19.
