A Look Back at Weldon Spring
Weldon Spring was officially planned out in 1864. The community got its name from a natural spring nearby. A post office opened in Weldon Spring in 1875 and stayed open until 1957.
Wartime Factories
In 1941, the United States Army bought a large area of land around Weldon Spring. They built a huge factory called the Weldon Spring Ordnance Works. This factory was the biggest explosives plant in the United States. It made materials like TNT for the Allied forces during World War II. The factory closed on August 15, 1945, soon after the war ended. Most of the land was then sold.
After the war, in 1945, there was an idea to put the United Nations Headquarters in this area.
Uranium Plant and Cleanup
In 1955, the United States Atomic Energy Commission built a different kind of factory. This one processed uranium ore. The Weldon Spring Uranium Feed Mill Plant made a material called "yellow cake uranium ore." This plant closed in 1966 and was left empty for 20 years.
The site became contaminated with a lot of materials, including radioactive uranium. The U.S. Department of Energy started a big cleanup project in the late 1980s. They finished the cleanup in 2001. Now, there is a large, safe mound of covered material on the site.
