Water pollution

Water pollution refers to the contamination of water bodies—such as rivers, lakes, oceans, and groundwater—by harmful substances or pollutants. These pollutants can include chemicals, toxins, heavy metals, sewage, and plastics. Water pollution can result from various sources, including industrial discharges, agricultural runoff, wastewater, and improper waste disposal. It negatively impacts aquatic ecosystems, harms wildlife, and poses risks to human health by affecting drinking water quality and food sources.
