Parts of Delhi may face a water crisis today as ammonia levels rise in Yamuna

Parts of Delhi may face a water crisis today as ammonia levels rise in Yamuna.

Parts of the national capital are expected to face a serious water crisis today as ammonia levels have risen in the Yamuna River. The acceptable limit is 0.5 ppm. Ammonia levels frequently rise in the Yamuna.

The high level of ammonia present in the water makes it difficult for aquatic organisms to sufficiently excrete the toxicant, leading to accumulation of toxins in internal tissues and blood, and potentially death.

The increase in ammonia levels in the Yamuna has greatly affected water production at four main water treatment plants: Sonia Vihar, Wazirabad, Chandrawal and Okhla.

“The water supply will be affected in various areas of the national capital on Sunday morning and evening. Increased ammonia pollution and high algae content in the Yamuna has triggered the crisis,” said the Delhi Jal Board (DJB) in a statement.

Water from the Wazirabad pond is drawn for treatment at the Wazirabad, Okhla and Chandrawal treatment plants. The treated water is then supplied to central, south and west Delhi.

Ammonia is an indicator of pollution in the river, and the level on Saturday was around 2.2 parts per million, according to a DJB official.
