Water pollution refers to the contamination of water bodies due to harmful substances, which can drastically impact ecosystems, animal health, and human health. Key causes include industrial discharges, agricultural runoff, and insufficient waste management, leading to diseases and ecosystem disruption. Preventive measures such as improving sewage treatment, educating the public, and implementing environmental laws are essential to mitigate this growing concern.

1. Presentation on Water Pollution

2. Water pollution is the contamination of Water
bodies(e.g. lakes, rivers, oceans, aquifers and
groundwater). This form of environmental
degradation occurs when pollutants are
directly or indirectly discharged into water
bodies without adequate treatment to remove
harmful compounds.

3. Types
1. Surface water pollution
2. Ground water pollution
3. Microbial pollution
4. Oxygen depletion
pollution
5. Nutrient pollution
6. Suspended matter
pollution
7. Chemical pollution
Sources
1. Direct Sources
2.Indirect Sources
o Direct Sources: Direct sources
include effluent outfalls from
factories, refineries, waste
treatment plants etc..
o Indirect Source: Indirect
sources include contaminants
that enter the water supply
from soils/groundwater
systems and from the
atmosphere via rain water.

4. Water pollutant is a substance that pollutes water. The top
three water pollutants are dirt, bacteria, and nutrients.
Other pollutants are
 Heavy metals
 Acidity caused by
industrial discharges
 Chemical waste
 Fertilizers from
agricultural use
 Silt from construction
sites, burn operation etc.
 Chemical from cosmetics
products

5.  As the world’s population grows, the demand for water mounts and
pressure on finite water resources intensifies.
 Climate change, which is also closely tied to population growth, will
also lead to greater pressures on the availability of water resources.
 We do know that the population will continue growing, and this will
impact water availability.
 Investing in efforts that slow the rates of population growth through
increasing access to voluntary family planning services can help ensure
that ample water is available for global food production, ecosystem
health and social stability.

6. Effects on Ecosystem
-Ecosystems can be severely affected or damaged
by water pollution.
-Contamination of groundwater from pesticides
causes damage to the reproductive system in the
wildlife ecosystem.
-Water pollution kills life that inhabits the water-
based ecosystem, disrupting the natural food
chain.
-The non-biodegradable pesticides and chemicals
cause mass destruction of aquatic life.

7. Effects on Animal Health
 Water pollution kills life that depends on these water
bodies.
 Fishes and the aquatic organisms are poisoned due to
industrial chemicals and agricultural pesticides.
 Oil spills in water causes animals to die as they ingest it
or come across it. Oil cannot be dissolved in water so it
causes suffocation in fish and birds.
 Animals that eat dead fish from contaminated streams
are affected.
 Fish, birds, dolphins and many other animals are killed
by pollutants in their habitat.

8. Effects on Human Health
 Diseases like hepatitis are caused by eating
seafood that is poisoned or contaminated.
 In developing nations, there are frequent outbreaks
of cholera and diseases due to poor drinking water
quality from contaminated waters.
 Polluted drinking water causes cholera or typhoid
infections and also diarrheal.
 Chemicals like fluoride, arsenic, lead, chlorine and
petrochemicals in water can causes adverse effect
on human health.
 Arsenic poisoning cause serious liver and nervous
system damage, vascular disease and skin cancer.

9. • Encourage smart agricultural practices.
• Reduce urban/suburban runoff of lawn fertilizers and
pesticides...
• Prevent further destruction wetlands, and reestablish
them wherever possible..
• Improve sewage treatment.
More specifically, we should..
• Get going on fixing outdated municipal water treatment
plants.
• Fully fund the Clean Water State Revolving Fund.
• Help localities set up programs that ensure system
maintenance and monitoring

10.  Educating the public about its harmful effects to
human and the environment.
 Be careful about what you throw down your sink
or toilet. Do not throw paints, oil or other forms of
litter down the drain.
 Take precaution while using pesticides and
fertilizers. Do not overuse them.
 Do not throw litter into rivers or lakes. Make sure
to collect the litter and put it in a nearby dustbin.
 Implementing strong environmental laws.
 Refuse water pollution, recycle water, and reduce
use of water.

11. In this scenario, Water Pollution has become one of
the biggest concerns in many developing countries all
around the world.
Groundwater contamination, lack of knowledge on
how to use water properly and poor sanitation
systems are causes of water pollution. Moreover
wastes dumped from factories into the sea or river
body when drank or used by many people cause
arsenic damage which is very problematic for us.
There are ways to fix and even get rid of such a huge
problem once and for all. If preventive measures are
not taken, this will continue to be a very life
threatening problem all over the globe.
