4. Water Matters : Dilemma & Crisis

5. Water Pollution : Definition

6. Water Pollution : Causes & Sources

7. Water Matters Approach


Water Cycle

• 70% of the earth’s surface – rivers, sea, rivers.

• Water sources :– Surface Water– Groundwater


Water /Hydrological Cycle


Human and water

• Human body : 65 – 75% consists of water• Function:

- Body immmune-cooling, dilution

- Sel metabolisme-water transport

- Neutralize and to remove excess toxics in

body system.


• Status of :– Water resources– Water supply– Water quality

Current condition/ Scenarios


• Colour – Organic and inorganic (mineral and metal)

• Organic – humus/plant – yellowish - chocolate

• Steel/ corrosion – Distribution pipe system)

• Manganese – in soil – chocolate to blackish

Water Matters:


• Development– Environmental Destruction– Water demand– Water system– Water quality

Water Dilemmas


Pollution

• “Undesirable change in the physical,

chemical, or biological characteristics of

the air, water, or land that can harmfully

effect the health, survival, or activities of

human or other living organisms”.


Pollution

?What is Water Pollution


Water Pollution

• “Body of water is adversely affected

due to the addition of large amounts of

materials to the water. When it is unfit

for its intended use, water is

considered polluted”


Pollution sources

• POINT SOURCES

- Known sources e.g. domestic sewage, industrial discharges

• NON-POINT SOURCES

- Unknown sources e.g. urban and agricultural runoff


Pollution

?Water are PollutionSources?


Water Pollutant Sources

3 categories :

• Municipal-residential/domestic or business area

• Industrial-factories: textile, chemicals etc

• Agricultural-fertilizer, insecticide and pesticide


Water Pollutant

1) Oxygen demanding wastes2) Disease causing agents3) Plant nutrients4) Synthetic organic compounds5) Oil6) Inorganic chemicals and mineral substances7) Sediments8) Radioactive materials9) Heat


Pollution

?Why treat Water


Pollution

To prevent the spread of diseases

To protect water resources

To fulfill water demand


Approach

• Prevention

• Control

• Rehabilitation


Approach


• Typhoid Fever

• Itai-Itai

• Cholera

Water Diseases


Read it loud!!!!!

“Water is undoubtedly the most precious natural resource that exists on our

planet. Without the seemingly invaluable compound comprised of hydrogen

and oxygen, life on Earth would be non-existent: it is essential for everything

on our planet to grow and prosper. Although we as humans recognize this

fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently,

we are slowly but surely harming our planet to the point where organisms

are dying at a very alarming rate.

In addition to innocent organisms dying off, our drinking water has become

greatly affected as is our ability to use water for recreational purposes. In

order to combat water pollution, we must understand the problems and

become part of the solution “
