(a) whether the ammonia level in Yamuna river has increased to 1.8/2 PPM against the prescribed limit of 0.5 PPM due to discharge of industrial waste into the river;
(b) if so, the details thereof; and
(c) the steps taken by the Government in this regard?
THE MINISTER OF STATE FOR JAL SHAKTI & SOCIAL JUSTICE AND EMPOWERMENT
(SHRI RATTAN LAL KATARIA)
(a) & (b) Based on the water quality monitoring including that for ammonia levels in river Yamuna at Delhi carried out by Central Pollution Control Board (CPCB) and Delhi Pollution Control Committee (DPCC), it has been observed that ammonia levels has increased to 1.8 ppm and ranges from Below Detection Limit (BDL) to 38.8 ppm for the year 2019. Details are Annexed.
Increase in ammonia levels in river Yamuna is due to discharge of untreated wastewater and industrial effluents on account of inadequate sewage and industrial wastewater treatment facilities and inefficient utilisation of existing facilities.
(c) Various steps have been taken towards abatement of pollution in River Yamuna through interventions in form of augmentation of sewerage infrastructure, monitoring of industrial effluents etc. Under Namami Gange programme of Government of India, 24 projects costing Rs.4609 Crore have been sanctioned in State of Himachal Pradesh, Haryana, Delhi and Uttar Pradesh to abate pollution load into river Yamuna. With these projects, 1310.6 Million Litres per Day (MLD) Sewage Treatment Plant (STP) capacity will be created along with rehabilitation of 528.18 MLD STP. In Delhi, these include 13 projects at various stages of implementation costing Rs.2419 Crore aimed at creation of 1384.5 MLD sewage treatment capacity (including 386 MLD STP capacity through upgradation & rehabilitation). Two projects have been completed in Sonipat and Panipat creating STP capacity of total 70 MLD and rehabilitation of 75 MLD STPs.
