Hanford Washington is adjacent to the Hanford Site — the most contaminated nuclear site in the Western Hemisphere and the largest environmental cleanup project in US history. The site produced plutonium for nuclear weapons from World War II through the Cold War, leaving 56 million gallons of radioactive and chemical waste in underground storage tanks. Tank leaks have been documented, and the Columbia River — a regional drinking water source — flows along the site boundary. The Hanford Vit Plant under construction is designed to immobilize the waste but faces decades of additional work. Residents in Benton County should know their emergency notification systems and evacuation routes.
