The site was bought from local ranchers in the 1950s, and in 1955 the Atomic Energy Commission established it as a non-nuclear explosives test facility to support weapons development at the main laboratory. Groundwater contamination was detected in shallow aquifers on site in 1981. The EPA issued a Corrective Action Order in 1989, and the site was added to the Superfund National Priorities List in 1990. A site-wide Record of Decision setting cleanup remedies was signed in 2008.
