What is water pollution?
Water pollution can be caused in many ways, the most serious of which is urban sewage and industrial wastewater discharge. Indirect sources of water pollution include pollutants that enter the water supply from soil or groundwater systems and water that enters the atmosphere through rainwater.
Soil and groundwater contain residues from human agricultural practices and do not properly handle industrial waste. When harmful substances enter water bodies such as lakes, rivers, oceans, etc., dissolved in water, suspended in water or deposited on a bed, they exceed the self-purification effect of the water body itself, thereby reducing water quality and forming water pollution.
This will not only cause disasters to aquatic ecosystems, but also infiltrate and penetrate into groundwater, which may eventually become polluted water used in our daily activities, including drinking water, and thus affect people’s lives.
