Tyson Valley Powder Farm

State: Missouri
Location: St. Louis
Time Period: 1942-1949
Facility Type: Atomic Weapons Employer

Facility Description: The Tyson Valley Powder Farm was a storage site for radioactive materials in the late 1940s. Records show, for example, that at the end of 1946, 206,110 pounds of uranium metal were stored at this location for the Manhattan Engineer District.

*The Tyson Valley Powder Farm was originally a 2,620 acre facility used from 1945 through 1950, then again in 1951 through 1963 by the Department of Defense. This site was used to support the St. Louis Ordnance Plant, mainly for storage and as a testing facility for ordnance. Tyson has numerous bunkers once used for ordnance storage. Remnants of firing ranges and waste destruction areas also exist at the site.

Likely existing contaminants due to disposal, storage and destruction of ordnance related materials include heavy metals, nitroaromatics, various explosives and solvents. World War II era documents show that radioactive wastes were once transported to the facility for storage. Later documentation suggests that some radioactive wastes were to be shipped off-site. Washington University School of Medicine radiation experts conducted a survey in 1988 and found no evidence of radioactive waste or contamination at the site.

Of the old facility, 1,966 acres are now owned by the Washington University Tyson Research Center and 405 acres are now St. Louis County’s Lone Elk Park. Remaining acreage is under Interstate 44 and railroad easements and in West Tyson County Park.

Tyson Valley Powder Farm is listed as an Atomic Weapons Employer (AWE) site under the EEOICPA.
