What is in news : The National Green Tribunal (NGT) has directed Punjab and Rajasthan governments to submit quarterly compliance reports to Jal Shakti ministry about remedial action being taken to curb the inflow of effluent discharge into the Satluj and Beas.

Sources of Pollution :

  • Buddha Nallah (Tributary) is a major source of pollution in the river Sutlej
  • Untreated sewage waste from Ludhiana city sewage treatment plants is polluting Buddha Nallah
  • Another seasonal rivulet, Chitti Bein and its sub-drain, Kala Sanghian drain, in the Jalandhar district are equally responsible for high pollution in the Sutlej river. The untreated discharge from Jalandhar’s leather goods industry is one of the major reasons behind Chitti Bein’s pollution.

Impact on Indira Gandhi Canal:

  • The Indira Gandhi Canal is the longest canal in the country.
  • It starts from Harike Barrage, a few kilometres below the confluence of the Satluj and Beas rivers in Punjab, flows through Ludhiana and terminates in the Thar Desert in northwest Rajasthan.
