The River Ganga is believed to be the longest
and one of the most sacred rivers in India. It
originates from the Gangotri glacier in the
Himalayas and empties into the Bay of Bengal in
eastern India. During its course it travels a
distance of about 2,525 km and covers around
8,61,404 sq km area of its basin. The river is
regarded as a goddess by the people. In spite of
its sacredness, the people of India have never
ever hesitated in polluting the river by their
reckless and selfish activities. Today, Ganga
pollution is one of the major issues that have
in certain ways affected our country, both
directly and indirectly.
Industrial effluents are the chief source of
pollution in the Ganga. Several factories, such
as leather, textile, rubber, plastic, etc. which
have evolved along the banks of the river,
discharge their poisonous effluents in the river
water without treating them properly. The second
major contributor of pollution of Ganga River is
the untreated sewage discharged from drains of
the cities into the river. According to a recent
survey, around 1 billion litres of untreated,
raw sewage are dumped in the river on a daily
basis. If not checked immediately, this figure
is going to increase by 100% in the coming 20
years.
The third major source of Ganga pollution is the
dumping of carcasses of humans and animals into
the river. Many of the human dead bodies that
are cremated on the ghats of the river are
immersed into the river with religious belief
that their souls will have a direct path to
heaven. Human excreta and washing of dirty
things along the river banks have also immensely
contributed to river pollution. Crowded fairs
along the river banks are another reason for the
contamination too. The bacterial count of the
water sharply increases with the arrival of
pilgrims during these fairs.
As per the recent studies conducted by the
Central Pollution Control Board, it is estimated
that there are six major points on the 2,525 km
course of the river Ganga where the water gets
polluted. Kanpur and Calcutta are the most
heavily contaminated spots. Varanasi and Kannauj
are somewhat lesser polluted spots. Allahabad
and Patna are further less polluted spots.
Studies by West Bengal Water Pollution Control
Board have revealed that bacteria counts in the
river water between Diamond Harbour and Uluberia
in Howrah district are alarmingly high. At
present chemical toxics and other bacteria found
in the Ganga water are 3000 times above the safe
limit prescribed by World Health Organization
(WHO). The level of Coliform bacteria is around
2800 times more than the limit suggested by the
WHO as safe.
Various measures have been introduced by the
government to tackle Ganga pollution. Ganga
Action Plan (GAP) in 1985 and Namami Ganga
programme are two such initiatives. Besides
these, the government has taken up the task of
redevelopment of river ghats and setting up R&D
projects and Waste and Disposal Treatment plants
for cleaning the river water.
Ganga pollution, if not checked immediately can
pose serious threat to our health and economy in
the coming years. The task of purifying the
water of our most important river not only lies
with our government but also with us. The best
way we can help the government in this work is
by refraining from polluting the Ganga in any
manner. Only intense public awareness can save
Ganga pollution.
