The problem of the pollution of river Ganga by the inaction of the municipalities was brought to light…

The pollution of the Ganga caused by the failure of municipal bodies to treat sewage was dealt with in "M.C. Mehta v. Union of India (1988)", the Ganga Pollution (Municipalities) case, in which the Supreme Court directed the Kanpur Nagar Mahapalika and other municipalities along the river to perform their statutory duties. The earlier "M.C. Mehta v. Union of India (1987)" decision concerned the discharge of trade effluents by the Kanpur tanneries.
