Industrial effluents and sewage water are being diverted to the river Ganga by the cities and towns through which it passes. Nestled on the banks of Ganga, Kanpur, a highly urbanized and industrial city is polluting it most. Apart from the Government of India’s recently constituted National Ganga River Basin Authority, civil societies and NGOs too are putting rigorous efforts to make Ganga pollution free.
