The Buriganga River in Bangladesh has become heavily polluted over the past few decades. Once a source of drinking water and important for trade, the river is now close to biological death due to pollution from Dhaka's growing population. Sewage, waste from factories and tanneries, and oil spills have turned the river black and killed all fish. Solutions are needed such as wastewater treatment plants, dredging the riverbed, and controlling pollution from industries. With concerted efforts, it may be possible to restore the river as was done with London's Thames River.

2. INTRODUCTION
 Buriganga river is a stream In Dhaka division,
Bangladesh with the region font code of Asia Pacific.
 In the 20th century the water table and river became
polluted by polythenes and other hazardous substances
from demolished buildings near the river banks.
 The water of the Buriganga is now so polluted that
all fish have died, and increasing filth and human
waste have turned it like a black gel. Even rowing
across the river is now difficult for its smell so bad.

3. INTRODUCTION (CONTD..)
 This vital river however has become extremely polluted
and close to biological death for several reasons.
 For this, the sources and occurrences of river pollution
should be studied carefully and deserves an urgent
adoption and implementation of necessary measures to
recover the natural ecosystem of the river sand to restore
the water quality of the river Buriganga

4. BURIGANGA BEFORE 40-50 YEARS
 During 1610 Buriganga was a prime location for
trade for Mughals, made Dhaka their capital.
 Buriganga was once the main source of drinking
water for Dhaka residents
 The river was crystal clear.
 In the past Buriganga was
economically very important
to Dhaka.

5. POLLUTION
 The Buriganga River in Dhaka has become heavy
polluted from sources such as waste flowing into the
river, oil spills from boats and building structures
appearing on the river banks.
 The Buriganga river is afflicted by the intolerable
problem of pollution. The chemical waste of mills and
factories, household waste, medical waste, sewage, dead
animals, plastics, and oil are some of the Buriganga's
major pollutants.

6. POLLUTION SOURCE
• Pollutants are mainly generated in and around the city
through domestic, commercial and industrial activities
• Wastewater and sewage generated in the city are carried
into the river system through numerous outlets. The river
is affected along its course by both point and nonpoint
sources of pollution.

7. POLLUTION SCENERIO
 Buriganga river extremely polluted and it is close to
biological death for several reasons. The
tremendous increase in population (12 million) of
Dhaka City over the last three decades has created
enormous environmental problems. Human sewage
coupled with municipal garbage, the disposal of
solid waste and drainage problems are the main
reason.
 River depth decreasing due to sludge deposition
hence affecting the navigation.
 Tanneries of Hazaribagh, chemical industry of
Tejgaon and many other factories poisonous
wastes are falling down in the river without any
treatment.

8. POLLUTION SCENARIO (CONT…)
o Human excreta’s and other waste from the floating
vessels are spilled. These wastes contaminate the river
water affecting its aquatic life and ecological health.
 From the launches and engine vessels in Sadarghat and
dockyard areas, there are discharges kerosene and Mobil
oil.

9. REMEDIAL MEASURE
 Environmental degradation is widely observed but the
key issue is to do something for the ecological
restoration of the environment. Early implementation of
efficient management practices will save the Buriganga
River. It has been seen that this river has considerable
pollution assimilation capacity which provides
considerable opportunity for improving water quality.

10. REMEDIAL MEASURE (CONT…)
 It is essential to make provision for protection and
improving water quality of the Buriganga river to
sustain the ecosystem in this river and overall
environment of the Dhaka city.
 Hazaribagh tanneries are responsible for causing
pollution in the Buriganga river by the contribution
of toxic and persistent pollutants, for that an Effluent
Treatment plant (ETP) should be established
without delay.
 Proper dredging of the existing river and removing
non degradable matters from the river bed.

11. CONCLUSION
 River is a vital natural resource which water is essential
for a multiplicity of purposes
 One of our inspiration or ideal could be the famous River
Thames in England. This had a worse scenario than our
Buriganga. No one can imagine how it was during the
20th century. The River Thames was named ‘The Great
Stink’ in 1858 as all the sewage line was connected with
the River Thames. Environmental officials now say the
Thames is the cleanest.
 It took 20 years of double efforts to complete and allow
wildlife back into river. And now the River Thames water
is supplied for drinking water and there was a expansion
of bankside development which resulted in an
economical gain as well.

12. CONCLUSION (CONT…)
 From this we can learn that it is not impossible to
bring back our Buriganga to its life.
 Buriganga River may bring many benefits to us
such as boating, fishing, tourism, transportation,
industry, power stations and makes people enjoy
many popular and interest sports.
 There was a campaign on "Save Buriganga, Save
Lives” by government to have a positive step to
save Buriganga.
