Water pollution control refers to the methods and practices used to manage and reduce the contamination of water bodies, such as rivers, lakes, and oceans. This involves regulating the discharge of harmful substances, treating wastewater, and implementing policies to protect water quality. Effective control measures help ensure safe drinking water and preserve aquatic ecosystems. Various organizations, including the Environmental Protection Agency (EPA), play a crucial role in enforcing laws and guidelines for water quality. Techniques like bioremediation, which uses microorganisms to break down pollutants, and filtration systems are commonly employed to clean contaminated water.
