Ammonia in Yamuna water
The National Green Tribunal on 16 February 2018 directed the Delhi and Haryana governments to hold a meeting to resolve the issue of high ammonia content in the water being provided to the national capital.
- The tribunal directed them to submit the result of the meeting by February 21 and posted the matter for hearing on February 22.
- The NGT also noted that the Supreme Court had passed an order where Haryana was directed to supply sufficient water and keep reservoirs of Wazirabad and Haiderpur to their optimum capacity.
- During the proceedings, the Central Pollution Control Board (CPCB) submitted its analysis report of ammonia at Tajewala in Haryana, Wazirabad water treatment plant, Okhla and ITO barrage in Delhi.
- According to the report, ammonia level at Hathnikund Barrage 0.6 mg per litre, 1.9 mg per litre at Wazirabad, 24.9 at ITO barrage on February 14 while at Okhla water treatment plant it was 0.8 mg per litre on February 15.
- Acting on concerns over the health of the people of Delhi, the tribunal had directed the CPCB to analyse samples of Yamuna water at four points on DJB’s plea alleging high ammonia content in the water being provided by Haryana to Delhi.
- DJB, which supplies water to the city, had approached the tribunal demanding that Haryana be asked to take urgent steps to check the “dangerous level of ammonia” in river Yamuna.
- The petition claimed that the water being released by the state was so polluted that it cannot be treated for drinking. It may cause “a huge and irreparable loss to the citizens of Delhi and has a potential for a grave health crisis and water crisis in the National Capital Region (NCR).
- The petition also claimed that when the water enters Haryana, the ammonia level is nil and very much treatable, whereas when the water enters Delhi, the level is very high.
