Timeline
The U.S. Environmental Protection Agency was established in 1970 to consolidate in one agency a variety of federal research, monitoring, standard-setting and enforcement activities to ensure environmental protection. EPA's mission is to protect human health and to safeguard the natural environment—air, water, and land—upon which life depends. For more than 30 years, the EPA has been working for a cleaner, healthier environment for the American people.
