Ammonia in Yamuna up again

In News
  • Water supply was disrupted in parts of Delhi once again when ammonia levels in the Yamuna river remained high according to the Delhi Jal Board (DJB).
  • The concentration of ammonia in the river was 7.4 ppm (parts per million), seven times the level of around 1 ppm that the Delhi Jal Board’s water treatment plants (WTPs) can process. 
Ammonia
  • Ammonia is a colourless gas and is used as an industrial chemical in the production of fertilisers, plastics, synthetic fibres, dyes and other products.
  • It consists of hydrogen and nitrogen. In its aqueous form, it is called ammonium hydroxide.
  • This inorganic compound has a pungent smell.
  • Occurrence: Ammonia occurs naturally in the environment from the breakdown of organic waste matter.
  • It is lighter than air.
Measures needed
  • Stringent implementation of guidelines against dumping harmful waste into the river.
  • Making sure untreated sewage does not enter the water.
  • Maintain a 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.
