The Hanford site, a 580-square-mile section of semi-arid desert in southeast Washington, was established in 1943 as part of the Manhattan Project to produce plutonium for national defense. Hanford produced nearly two-thirds of the plutonium used in the US nuclear weapons stockpile, including materials for the Trinity Test and atomic bombs used to help end World War II.
