Water has great importance for
human life and all kinds of animals and
plants. Wherever there is water there is
life and the Earth is the only place on the
planet all countries. But water is heavily
contaminated with significant impact on
the lives of every living thing on earth.


• So we conducted
group learn about
water pollution issues
may apply to this
situation rediscover
life with a source of
fresh water for the
earth


I. Concept
1. Environmental
“Environmental factors including natural
and man-made material factors closely
related to each other, surrounded by
people, affecting life, production and
survival, human development and
natural"


2. Environmental pollution

Environmental pollution is the state of
the environment contaminated by
chemical, biological, radiation, noise, ...
affecting human health and other living
organisms. Environmental pollution is
caused by humans and human
management.


3. Pollution of the water environment.
Water pollution is a phenomenon
waters such as rivers, lakes, sea, ground
water ... is the human activity of
contaminating substances can cause harm
to humans and the creatures living in the
wild.


II. Situations
• Pace of urbanization
and rapid
industrialization and
increasing population
pressure on
increasingly heavy on
water resources in the
territory.


• The water

environment in
many urban areas,
industrial zones
and craft villages
increasingly
contaminated by
waste water,
waste gas and
solid.


• In large cities hundreds of industrial
production facilities are polluting the
environment because there is no
water works and waste treatment
facilities.


• For example, in the city of Taiyuan,
industrial waste water discharged from the
base paper production, iron and steel,
non-ferrous metallurgy, coal mining in the
dry season, the total volume of
wastewater in the region accounts for
about 15% of river flow Bridge,
papermaking wastewater with a pH from
8.4 to 9 and 4 mg NH4 / 1, high levels of
organic matter, brown sewage smell
unpleasant.

• Water pollution caused by industrial
production is very heavy.
• In addition, water pollution in rural
and agricultural areas is also very
serious


• On the status of water pollution in rural
and agricultural areas, Vietnam now has
nearly 76% of the population live in rural
areas where infrastructure is backward,
the majority of waste human and cattle
should not be treated permeable ground
or washed make pollution of surface water
and organic growing microorganisms


• In agricultural
production due to
abuse drugs and
plant protection, the
water in rivers, lakes,
canals contaminated
greatly affect the
water environment
and people's health.


III. Cause

Due to
indiscriminate
discharge of
waste into
rivers , streams,
lakes where
water.

1.


2. Discharge of
wastewater from
manufacturing
plants , industrial
parks and export
processing zones
untreated into
rivers, lakes
polluting surface
water and ground
water .


3. Due to floods

4. Due to population
growth

6. Systems are not
dredged canals
leading to
accumulation of large
amounts of organic
matter from sewage ,
garbage and causing
siltation affect the
drainage of water


7. Landfill does not
meet the technical
requirements ,
leachate from
garbage seep into
groundwater or
runoff into canals on
the ground .


8. The surface water
flow in rivers and
canals also
contaminated by oil
from ship traffic ,
transportation or
other incidents on
the river , the sea .

9. And many other causes also
cause water pollution.


IV . Sequel


1.For people
• Cause many
dangerous
diseases
examples cancer,
mutations.
Especially cancer


• Aaste from the
mining industry,
coal, gas,
plumbing lead.
Anemia, kidney
disease.
neurological
disorders,
environmental
destroyed.


• Harmful bacteria

in contaminated
water from
human wastes
human and
animal causes
cholera, typhoid
and polio.


• lack of clean water for the works

• And many other consequences as ecological
balance, beauty, animals and plants living on the
water environment.
