High level of AMMONIA in YAMUNA Water.

Why YAMUNA is highly POLLUTED?

YAMUNA

Yamuna River accounts for more than 70% of Delhi's water supply.

At Hathini Kund Barrage in Haryana, most of the water of Yamuna River is Diverted. 

Delhi - drinking water is extracted from the river at Wazirabad (North East Delhi).

After Wazirabad Barrage, what flows is mostly untreated sewage and refuse from homes, Run off from storm water drains and effluents from unregulated industry.

 AMMONIA

Ammonia is a colourless gas with a pungent smell.

It is used as an industrial chemical in the production of fertilizers, plastics, synthetic fibers, dyes and other products.

Ammonia occurs Naturally in the environment from the breakdown of organic waste matter.

Anthropogenic sources of Ammonia- industrial effluents, sewage.

AMMONIA IN YAMUNA

Effluents from dye units, distilleries and other factories in upstream districts in Haryana.

Raw sewage inflow into Yamuna.

Haryana had opened the gates of drains that had Stagnant water with a high pollutant concentration, following heavy rainfall.

AMMONIA TOXICITY

Concentration of above 1ppm - toxic for fishes.

Ingestion of water having Ammonia level of 1ppm may cause damage to internal organs in Humans.

The acceptable maximum limit of Ammonia in drinking water, as per the Bureau of Indian Standers, is 0.5ppm.

DELHI JAL BOARD

Delhi Jal Board said that the concentration of the Ammonia was 3ppm in raw water of Yamuna.

The DJB presently has the capacity to treat approximately 0.9ppm.

DJB treats Ammonia by mixing non polluted water from other sources.

SOLUTION

Maintain sustainable minimum flow, called the Ecological flow.

This is the minimum amount  of water that should flow throughout the river at all times to sustain underwater and Estuarine Ecosystems and Human Livelihoods and for self regulation.
