water pollution
- 2.
- 3. Water pollution is major problem in global warming context . It has been suggested that it is leading worldwide cause of death and diseases. And that it accounts for the deaths of more than 14000 people daily. An estimated 700 million Indians have no access to proper toilet. 1000 Indian children's are die daily because of diarrheal sickness.
- 5. If the pollution comes from single source is called point source pollution If the pollution come from so many sources is called non point source pollution .
- 6. Examples of point sources :
- 7. Examples of non point source : Excess fertilizers, herbicides, and insecticides from agricultural lands and residential areas; Oil, grease, and toxic chemicals from urban runoff and energy production.
- 8. Sewage and waste water Everyday, we cook, do laundry, flush the toilet, wash our cars, shower and do many things that use water. Think about how we use water in schools, hospitals and public places. Septic Tanks Every domestic (home) toilet is connected to septic tank usually located outside the house. Each time poop is flushed down the toilet, it goes into this tank, where the solid part is separated from the liquid part.
- 9. Ocean and marine dumping Again, think of the rubbish we all make each day. Paper waste, food waste, plastic, rubber, metallic and aluminum waste. In some countries, they are deposited into the sea. All these waste types take time to decompose. Underground storage and tube leakages Many liquid products (petroleum products) are stored in metal and steel tubes underground. Other sewage systems run in underground tubes. Overtime, they rust and begin to leak. If that happens, they contaminate the soils, and the liquids in them end up in many nearby water bodies Atmospheric Atmospheric deposition is the pollution of water bodies caused by air pollution.
- 10. Death of aquatic (water) animals The main problem caused by water pollution is that it kills life that depends on these water bodies. Disruption of food-chains Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels.
- 11. Eventually, humans are affected by this process as well. People can get diseases such as hepatitis by eating seafood that has been poisoned. In many poor nations, there is always outbreak of cholera and diseases as a result of poor drinking water treatment from contaminated waters. Oil drilling, refining and transportation have long been a major issue especially with marine pollution.
- 12. Use Water Wisely By conserving water, the amount of wastewater needing treatment and disposal will be reduced. Overwatering and runoff can carry pollutants into the storm drain system. Use and Dispose of Hazardous Substances Properly Always read the product label and choose the least toxic alternative. Motor oil, paints, solvents and other chemicals should not be poured on the ground or down storm drains, because they can pollute our streams and ocean.
- 13. Improve Housekeeping Report water leaks so that we may any fix water leaks on our campus by replacing faucet washers and toilet flappers as needed. Study Storm Water Management Students may elect to learn more about hazards associated with illicit discharges to our storm drains and streams, then develop steps that can be taken to reduce storm water pollution. Educate Others Offer an individual or class project to inform others about protecting our ocean from pollution.
