Water pollution is the contamination of water bodies such as rivers, lakes, oceans, and groundwater by harmful substances and pollutants. These pollutants can include chemicals, waste products, plastics, and biological agents, which degrade water quality and pose risks to human health, aquatic ecosystems, and the environment. Water pollution can result from various sources, including industrial discharges, agricultural runoff, sewage spills, and improper waste disposal. The adverse effects of water pollution are wide-ranging, affecting drinking water supplies, disrupting natural habitats, harming wildlife, and reducing the usability of water for recreational and commercial purposes. Effective management and regulatory measures are essential to prevent and mitigate water pollution and protect water resources for future generations.
