Grand Junction Operations Office

In March of 1943, the US Army Corps of Engineers leased space in Grand Junction, CO to enable the construction of a uranium refinery and local recovery sites for the operations of the Manhattan Project. In August of 1943, the land was purchased and the site became the U.S. Department of Energy’s Grand Junction Projects Office, later becoming the Grand Junction Operations Office in the ’50s. Local vanadium mill tailings were sent to the GJOO location where they were refined into uranium oxide for nuclear weapons during the Cold War. Employees of the GJOO were potentially exposed through direct radiation and inhalation during the site’s operations.
