Weldon Spring Quarry
Location
Weldon Spring, Missouri
In 1958, the U.S. Atomic Energy Commission (AEC) acquired title from the U.S. Department of the Army (Army) to an inactive quarry that had been on the Weldon Springs Ordnance Works land. The quarry was used by the AEC as a dumping ground for chemical and radiological waste products, including the demolished Destrehan Street Plant in St. Louis.
Surface decontamination of the quarry was completed in October 2002.
