- 2. What is waterpollution 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.

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 Surface water pollution Ground water pollution Microbial pollution Oxygen depletion pollution Nutrient pollution Suspended matter pollution Chemical pollution 1.

- 4. Water Pollutants • Waterpollutant 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 waterneeds • 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 ofWater 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 onAnimal • 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 onHuman 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 waterPollution 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 ForWater 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.
