Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include lakes, rivers, oceans, aquifers and groundwater. Water pollution happens when toxic substances enter water bodies such as lakes, rivers, oceans and so on, getting dissolved in them, lying suspended in the water or depositing on the bed. This degrades the quality of water.
