1. PROJECT

2. The sum of total of all surroundings of a living organism including natural
forces and living things which provide conditions for development and growth
as well as danger.

3. WATER AND ITS POLLUTION

4. 70% total human body wt.
30 – 40% bone mass.
Body functions:
 Absorption of oxygen at alveoli.
 Control of body temperature.
 Blood component.
 Digestion in kidneys and intestine.
Alteration of 10% body content – health problem.
Alteration of 20% body content – death.

6.  Water pollution
 Any physical or chemical change in water that adversely affects the health of humans and other organisms
 Varies in magnitude by location
 Major water pollution issue globally
 Lack of disease-free water
 Eight categories
 Sewage, disease-causing agents, sediment pollution, inorganic plant and algal nutrients, organic
compounds, inorganic chemicals, radioactive substances, and thermal pollution

7. SOURCES OF WATER
POLLUTION
Pollution of clean water resources
Erosion at water catchments areas.
Erosion of rivers.
Effluent from mining site.
Effluent from industry area.
Effluent from farming area.
Effluent from domestic area.

8. WATER POLLUTION
Will cause
Soil contamination.
Air contamination.
Food chain contamination.
Esthetic. Breeding of
diseases vector.
Spreading of water borne
diseases.
Food poisoning.
Skin problem.
Lack of clean water
supply for
Domestic demand.
Industry use.
Agriculture use.

9. Used for bathing
and washing
clothing
Sewage and
industrial waste
discharged into
river
Ganga Action Plan
initiated by
government
Construction of 29
sewage treatment
plants

10. DISEASE-CAUSING AGENTS
 80% of diseases in developing countries are due to
water supply contamination.
 4 – 5 million child died every year due to water
supply contamination.
 More than 1 million died after severe diarrhea.

11. Treated water distributed to
customers
Sewer lines bring sewage to
treatment plant
Sewage treated at sewage
treatment plant

12. Chlorine Dilemma
 Chlorine kills disease causing organisms
 Chlorine byproducts are linked to numerous cancers,
miscarriages and birth defects
 Peru stopped using chlorine
 1991- huge cholera epidemic that infected 300,000 people
Fluoridation
 Prevents tooth decay
 Linked to cancer, kidney disease

13. LAWS CONTROLLING WATER POLLUTION

14. CONCLUSION
SAVE EARTH FROM GETTING POLLUTED
