Why It Matters

Created in 1970, the U.S. Environmental Protection Agency (EPA), is the country's leading environmental governing body, employing approximately 17,000 people who oversee its programs from the Washington, D.C., headquarters, ten regional offices and laboratories and research centers across the country.

The EPA's mission is straightforward: to protect human health and safeguard the natural environment in the nation's states, territories and tribal lands.

The EPA, the joint creation of Congress and the White House under President Nixon, set up shop in Washington, D.C. on Dec. 2, 1970, when William Ruckelshaus was installed as the EPA's first administrator.

The EPA was established in response to a growing public demand for cleaner water, air and land, precipitated by several landmark environmental events, among them the catching on fire (not for the first time) of the Cuyahoga River in Cleveland in 1969, and the nation's celebration of the first Earth Day in April 1970. As such, the EPA was assigned the task of cleaning up the environment and developing and implementing regulations to protect it, and by extension, safeguarding human health.
