Pollution of River in India due to Untreated Waste Water Disposal

The major polluting
industries on the Ganga are the leather industries, especially near Kanpur,
which use large amounts of Chromium and other chemicals, and much of it finds
its way into the meager flow of the Ganga. Also, inadequate cremation
procedures contributes to a large number of partially burnt or unburnt corpses
floating down the Ganga, not to mention livestock corpses. 

The Ganga Basin, the
largest river basin of the country, houses about 40 percent of population of
India. During the course of its journey, municipal sewages from 29 Class-I
cities (cities with population over 1,00,000), 23 Class II cities (cities with
population between 50,000 and 1,00,000) and about 48 towns, effluents from industries
and polluting wastes from several other non-point sources are discharged into
the river Ganga resulting in its pollution. The NRCD records put the estimates
of total sewage generation in towns along river Ganga and its tributaries as
5044 MLD (Million Litres per Day). 

According to the Central Pollution Control
Board Report of 2001, the total wastewater generation on the Ganga basin is
about 6440 MLD.  Urban filth and industrial pollution are scientific
causes, but environmentalists believe that apart from industrial pollution and
sewage, the increase in number of slaughterhouse, dhobi ghats, crematoria and
slums are the major sources of pollution in these rivers. Every year, religious idols
are immersed in rivers which lose a little more of their life as they are
choked yet again.
