Water pollution occurs through dumping of industrial waste, sewage, and toxic agricultural substances into bodies of water. It affects agriculture by contaminating crops and soil fertility. Ecosystems are damaged as pollution warms water and forces species to relocate. Human health is impacted through skin problems, cancer, and sickness from swimming in or drinking contaminated water. Animal health suffers as pollution kills dependent wildlife. Treating polluted water for safe use is an expensive economic burden.

3. What is water pollution?
"Water pollution" is defined as the
addition of harmful or
objectionable material to water
bodies causing an alteration of
water quality.

4. How does water pollution occur?
Water pollution can occur via several
mechanisms, here are some common
causes:

5. Dumping of
“Industrial Waste
and Sewage” into
bodies of water.

6. Use of “Toxic
Substances” in
agriculture.

7. Accidental “Spills
from Oil Rigs”.

8. Effects of Water Pollution

9. Agriculture
The waste that we dump on water bodies gets
accumulated on surface water and ground
water, this will contaminate crops and cause
diseases to consumers and farm workers.
Depositions of deleterious chemicals in soil also
leads to loss of soil fertility.

10. Ecosystem
Ecosystems are destroyed by the rising
temperature in the water, as coral reefs are
affected by the bleaching effect due to warmer
temperatures. Additionally, the warm water
forces indigenous water species to seek cooler
water in other areas, causing an ecological
damaging shift of the affected area

11. Human Health
Swimming in and drinking contaminated water
causes skin rashes and health problems like
cancer, reproductive problems, typhoid fever
and stomach sickness in humans. Which is why
it’s very important to make sure that your
water is clean and safe to drink.

12. Animal Health
The main problem caused by water pollution
is that it kills life that depends on these water
bodies. Dead fish, crabs, birds, sea gulls,
dolphins, and many other animals often wind
up on beaches, killed by pollutants in their
habitat.

13. Economy
Improvement of water quality- Removal of
organic matter through aerobic decomposition;
chlorination to remove bacteria and suspended
solids; precipitation of salts, desalination, etc.
during water treatment is expensive for polluted
water
