Streamlined RI/FS planning for the groundwater operable unit at the Weldon Spring Site
The U.S. Department of Energy (DOE) is conducting cleanup activities at the chemical plant area of the Weldon Spring Site located in St. Charles County, Missouri, about 48 km (30 mi) west of St. Louis and 22 km (14 mi) southwest of the City of St. Charles. The 88-ha (217-acre) chemical plant area is chemically and radioactively contaminated as a result of uranium processing activities conducted by the U.S. Atomic Energy Commission during the 1950s and 1960s. The Army also used the chemical plant area for the production of explosives in the 1940s. The Weldon Spring Site chemical plant area was listed on the National Priorities List (NPL) in 1989. Adjacent to the chemical plant area is another NPL site known as the Weldon Spring Ordnance Works. The ordnance works area is a former explosive production facility that manufactured trinitrotoluene (TNT) and dinitrotoluene (DNT) during World War II. The ordnance works area covers 7,000 ha (17,232 acres); cleanup of this site is managed by the U.S. Army Corps of Engineers (CE).
