Ganga River Pollution

2. Introduction
• The river Ganga occupies a unique position in the cultural ethos of India.
• Millions of Hindus accept its water as sacred. Even today, people carry treasured
Ganga water all over India and abroad because it is "holy" water and known for
its "curative" properties.
• The Ganga rises on the southern slopes of the Himalayan ranges from the
Gangotri glacier at 4,000 m above mean sea level
• In the Budget document, the government’s allocation to the ‘National Ganga Plan
and Ghat works’ shows only ₹750 crore for 2019-2020

3. Importance of Ganga Basin in India
• Geographical coverage is the largest – 26% of India’s land mass
• Most populated basin – hosts 43% of India’s population
• Annual surface water potential – 28% of India’s total
• 38% of India’s total estimated utilizable water comes from Ganga Basin –
highest amongst all
• Estimated utilizable surface water in Ganga is 48%
• Nearly 40% of India’s total estimated replenishable ground water
resources comes from Ganga Basin

6. Present Situation
2009 2013
Sewage generation(MLD) 2,638 2,723
Treatment Capacity(MLD) 1,174 1,208
Gap(MLD) 1,464 1,514
%gap 55 55
Domestic Sewage: Sewage adds up to 85 percent of the river’s pollution load.
The 2009 and 2013 CPCB estimates are shown in the table:
MLD- Million liters per day
• Along the main river course there are 25 towns with a population of more than 100,000
and about another 23 towns with populations above 50,000. In addition there are 50
smaller towns with populations above 20,000. There are also about 100 identified major
industries located directly on the river, of which 68 are considered as grossly polluting.
• sixth most polluted river in the world.

8.  According to most recent data provided by CPCB, the actual measured discharge of
wastewater is 6,087 MLD which is much higher than the estimated discharge of
wastewater.
 As per the UECPCB study, while the level of coliform present in water should be
below 50 for drinking purposes, less than 500 for bathing and below 5000 for
agricultural use— the present level of coliform in Ganga at Haridwar has reached
5500.
 Industrial Wastewater:
 2013 CPCB estimates show that 764 industries in the mainstream of ganga consume 1,123
MLD of water and discharge 500 MLD of effluent.

9. • According to the study, the main cause of high level of coliform in Ganga is due to
disposal of human faeces, urine and sewage directly into the river from its starting point in
Gaumukh till it reaches Haridwar via Rishikesh.
• Nearly 89 million litres of sewage is daily disposed into Ganga from the 12 municipal
towns that fall along its route till Haridwar in 2013
• Environmental Biology Laboratory, Department pf Zoology, Patna University, showed the
presence of mercury in the Ganga river in Varanasi city. According to the study, annual
mean concentration of mercury in the river water was 0.00023 ppm. The concentration
ranged from NT (not traceable) to 0.00191 ppm. .
• As Ganga enters the Varanasi city, Hinduism’s sacred river contains 60,000 faecal coliform
bacteria per 100 millilitres, 120 times more than is considered safe for bathing.

10. • According to World Wide Fund for Nature (WWF) five rivers in Asia serving over 870
million people are among the most threatened in the world, as dams, water extraction and
climate change all take their toll. The Ganges, Indus, Yangtze, Salween-Nu and Mekong-
Lancang rivers make up half of the WWF’s “top ten” most threatened river basins.
• The Ganga river carries the highest silt load of any river in the world and the deposition of
this material in the delta region results in the largest river delta in the world (400 km from
north to south and 320 km from east to west).
• Spiritual dip in holy Ganga at Kumbh is not clean. The level of the Biochemical Oxygen
Demand (BOD) levels - used to measure of the level of organic pollution in the water - had
increased to 7.4 milligram per litre at the main bathing place, known as Sangam, since the
Kumbh started.

11. Kumbh Mela 2019: What’s happening to all the waste?
• Kumbh Mela 2019 is being organised in Prayagraj, Uttar Pradesh from January 15, 2019 to March
31 2019.
• Around ₹4200 crore will be allotted by the state government for the Ardh Kumbh 2019, over two
times more than it had spent on the last Kumbh held in 2013 and revenue generated is about 1.2
lakh crore
• About 199 projects of 16 government departments are underway under four phases which includes
a six-lane bridge over the river Ganga and a four-lane railway over-bridge worth ₹275 crore.
• Around 1.2 lakh toilets have been installed, 500 sanitation workers and 1,500 Swachhagrahis
(volunteers) have been deployed at the site. The Central Pollution Control Board (CPCB) has been
tasked to continuously monitor the water quality.

12. Contd..
• According to New Delhi-based non-profit Centre for Science and Environment (CSE),
the estimated amount of faecal matter produced during the 50 day-long Kumbh Mela is
around 18 times more than what the district produces daily.
• Based on this, we can estimate that the faecal matter to be produced by around 10 crore
tourists and pilgrims will be around 14,000 tonnes per day (assuming the maximum load
on auspicious days). If we add the current population of Prayagraj to the estimated
number of pilgrims, the amount of faecal matter produced in a day will increase to
15,000 tonnes.

13. Case study
Agency /researcher Year Results
Lakshminarayana 1965 most of the parameters decreased during rainy season
while no marked variation was observed during winters
and summers.
Saxena et.al 1966 the biological oxygen demand, i.e. B.O.D. varied from
5.3ppm (minimum) in winter to 16.0ppm (maximum) in
summer. The chloride ranged between 9.2 and 12.7 ppm
and the river was found to be alkaline in nature except in
rainy season.

Control Boards of
Uttar Pradesh, Bihar
and
Bengal
1981 According to this report sewage of 27 class I cities and
towns and effluents from 137 major industries were the
main source of pollution of the river. In addition cremation
of ad human bodies and dumping of carcasses aggrevated
the pollution of the river.

14. Kanpur-Varanasi-Allahabad : A Case Study

16. Kanpur-Varanasi-Allahabad
• Alone Uttar pradesh contribute 90% of ganga water
pollution of which In the Kanpur-Varanasi stretch,
3,000 MLD of domestic wastewater is discharged
into the river which is roughly half of its total load.

21. Cleaning Efforts … So far ..!!
❏ Ganga Action Plan
❏ The National Ganga River Basin Authority
(NRBA)
❏ Save Ganga Movement
❏ Role of Major Activists
❏ Namami Ganga

22. Ganga Action Plan
 launched in April 1986 in order to reduce the pollution load on the river.
 But the efforts to decrease the pollution level in the river became more. Therefore, this
plan was withdrawn on 31 March 2000, after spending Rs 901.71 Crore .
 Million litres of sewage was targeted to be intercepted, diverted and treated. Phase-II
of the program was approved in stages from 1993 onwards, and included the following
tributaries of the Ganges: Yamuna, Gomti, Damodar and Mahananda.

23. MajorActivists
 Acharya Jitendra
- National General Secretary of Ganga Mahasabha
- put a lot of efforts to abandon all state hydro-damprojects.
Nigmanand - fasted unto death, protesting against illegal mining happening in the district
of Haridwar (in Uttarakhand) resulting in pollution.
 Prof. G.D. Agrawal
- protested the building of dams in the Upper course ofGanges
- Manmohan Singh admitted publicly to cease any further hydroelectric damming of
the Ganga in Uttarkhand.

24. Namami Ganga
❏ In July 2014, the Government of India announced an integrated Ganga development project
titled “Namami Gange” launched by NDA Government and a sum of INR 2,037 Cr set
aside for this purpose.
❏ A sum of INR 100 Cr allocated for developments of Ghats and beautification of
River Fronts at Kedarnath, Haridwar, Kanpur, Varanasi, Allahabad, Patna
and Delhi in the current financial year.
❏ The interventions at Ghats and River fronts will facilitate better citizen connect and set
the tone for river centric urban planning process.

27. Meeting the challenge: opportunities
Problem flagged at appropriate
time
• River Ganga is still a living river (Dissolved Oxygen meets
the standard at majority of the segments)
• Rejuvenation efforts initiated with launch of ‘Namami
Gange’
Existing Institutions
• River Ganga declared as ‘National River’
• Prime Minister announced ‘Namami Gange’ Program
Sharing of international
experience
National Commitment and
Priority
• National Ganga River Basin Authority (NGRBA) – an apex
level Authority chaired by Hon’ble PM of India
• National Mission for Clean Ganga (NMCG) – implementing
body of NGRBA
• State Program Management Group (SPMGs) – in all 5 basin
states
• Successful experience of international rivers such as Rhine,
Danube, Thames, Murray-Darling, etc. provides learning for
Ganga Rejuvenation

28. National Ganga River Basin Authority (NGRBA)
• The Central Government has set up the ‘National Ganga River Basin Authority’
(NGRBA) vide gazette notification dated 20.2.2009 as a collaborative institution of
Central and State Governments under the Environment (Protection) Act of 1986 for
abatement of pollution of River Ganga.
• The objective of the authority is to ensure effective abatement of pollution and
conservation of the river Ganga by adopting a holistic approach with the river basin as
the unit of planning.

30. Ganga river water unfit for direct drinking, bathing: CPCB report
• A map released by the Central Pollution Control Board (CPCB) on 30th may,2019 shows high level of
coliform bacteria in the river. Only 18 spots have been found to be fit for bathing
• The six spots which were found fit for consumption under class A- fit for drinking after disinfection- are
Bhagirathi at Gangotri, Rudraprayag, Devprayag, Raiwala- Uttarakhand, Rishikesh, Bijnor and Diamond
Harbour in West Bengal
• On the banks of river Ganga, there are over 1100 industrial units which discharge their waste into the river.
Today, not a single industry is discharging black waste in the river. That is the level to which we have
brought it," Union Environment Secretary C K Mishra said. Mishra also said that the situation was not a
"happy"
• Sewage is a big issue. Work is going on and it will take a little while
