Presentation on Water Pollution

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.

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.

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

As the world’s population grows, the demand for water mounts andpressure on finite water resources intensifies.

Climate change, which is also closely tied to population growth, willalso lead to greater pressures on the availability of water resources.

We do know that the population will continue growing, and this willimpact water availability.

Investing in efforts that slow the rates of population growth throughincreasing access to voluntary family planning services can help ensurethat ample water is available for global food production, ecosystemhealth and social stability.

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.

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.

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.

• 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

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.

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.
