Observing that the counsel representing the State appeared to be clueless as to the measures to be adopted, Chief Justice Banerjee said, “At the end of the day, the pollution level in the flowing water has to be reduced to the extent possible. That is the duty of the State, and appropriate checks and balances should be introduced to ensure that the dumping of effluents into any flowing waterbody, whether by any industry or by local inhabitants, is completely prohibited if only to preserve the quality of water for downstream users.”
