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

4. Water Pollutants
• Water pollutant is a substance that pollutes
water. The top threewater pollutants are dirt,
bacteria,and nutrients.
• 1. Other pollutants are
• 2. Heavy metals
• 3. Acidity caused by industrial discharges
• 4. Chemical waste Fertilizers from
• 5. agricultural use
• 6. Silt from construction sites, burn operation etc.
• 7. Chemical from cosmetics products
5. Population and water needs
• As the world's population grows,the demand for
water mounts and pressure on finite water
resourcesintensifies.Climate change, which is also
closely tied to population growth, will also lead to
greater pressureson the availability of water
resources.We do know that the population will
continue growing,and this will
impact water availability.Investing in effortsthat
slowthe rates of population growth through
increasing access to voluntary family planning
services can help ensure that ample water is
available for global foodproduction, ecosystem
health and social stability.
6. The Effect of Water
Pollution
• Effects on ecosysrem
• -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
poisoneddue to industrial chemicals and
agricultural pesticides.
• Oil spilis in water causes animals to die as
they ingest it or
• come across it. Oil cannot be dissolved
in water so it causes
• suffocationin fish and birds.
• Animals that eat dead fish fromcontaminated
streams are affected.
8. • Effects on Human Health
• Diseases like hepatitis are caused by
eating seafoodthat is poisonedor
contaminated.
• In developing nations, there are
frequent outbreaks of cholera and
diseases due to poor drinking water
quality from contaminatedwaters.
• Polluteddrinking water causes
cholera or typhoid infections and
also diarrheal.
9. Solution to water Pollution
Encourage smart agricultural practices.
Reduce urban/suburbanrunoff of lawn fertilizers and pesticides...
Prevent further destructionwetlands, and reestablish
them wherever possible..
Improve sewage treatment.
More specifically,we should..
Get going on fixingoutdated municipal water treatment plants.
Fully fund the Clean Water State RevolvingFund. Help localities set up
programs that ensure system maintenanceand monitoring
10. Preventive Measures For Water Pollution
+ Educatingthe 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 environmentallaws.
> Refuse water pollution, recycle water, and reduce
use of water.
