The U.S. Environmental Protection Agency (EPA) is a federal agency established in 1970 to protect human health and the environment. It develops and enforces regulations based on laws passed by Congress, focusing on air and water quality, hazardous waste management, and chemical safety. The EPA also conducts research and provides education to promote environmental awareness. The agency works with state and local governments, as well as businesses and communities, to implement environmental policies. Key programs include the Clean Air Act, Clean Water Act, and the Superfund program, which addresses contaminated sites. The EPA plays a crucial role in ensuring a sustainable environment for future generations.
