and ground water.
• 2.4% Glaciers and Ice Caps
• 0.5% Fresh water that is unavailable
• 0.03% Water to drink (also use for
factories/ working)

3. What is water pollution?
Water pollution is the contamination of water
bodies, such as rivers, lakes, oceans and
groundwater by harmful substances that make it
unfit for human or animal use. Water pollution
can occur naturally but it is mostly caused by
human activities, such as industrial discharge,
agricultural runoff, sewage discharges and
improper disposal of waste.

4. Effect On Human Health
Contaminated water can harbor bacteria,
such as those responsible for diarrhea,
cholera, typhoid, hepatitis A, and polio.
• According to the UN, every year,
approximately 297,000 children under
five die from diseases linked to poor
sanitation, poor hygiene, or unsafe
drinking water.
• Increased risk of skin diseases.
• May increase the risk of cancer.

5. Sources of Water Pollution
The two chief sources of water pollution
can be
• Point source
• Non-Point source

6. Point source
Point source water pollution
refers to contaminants that enter
a waterway from a single,
identifiable source such as pipe
or ditch.
Example a factory or a city storm
drain.

7. Non-Point source
Non-Point source water pollution refers
to diffuse contamination that does not
originate from a single discrete source.
Example Fertilizers, pesticides and
manure from farms can contaminate
water bodies.
