How water polluted

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.

1. There are also less common causes of water pollution like accidental oil spills.
2. Many factories dispose of chemical waste by dumping the waste into lakes, rivers or the ground.
3. The pesticides that farmers use to eliminate insects can also reach surface water and groundwater in significant quantities.
4. Underground storage tanks for gasoline and other liquids can directly contaminate groundwater.
5. Salt placed on icy streets during winter also pollutes water, even though salt is not especially dangerous to people’s health.
6. Other sources of water pollutants include sewage and wastewater, septic tanks, and ocean and marine dumping. Soluble waste, or sewage.
