The Pueblo Chemical Depot is a facility located in Pueblo, Colorado, primarily used for the storage of chemical weapons. Established in the 1940s, it was part of the United States' efforts during the Cold War. The depot has been involved in the safe storage and eventual destruction of these chemical agents, in compliance with international treaties. In recent years, the Pueblo Chemical Depot has focused on the demilitarization process, which includes the destruction of stored chemical munitions. This effort is part of a broader initiative to eliminate chemical weapons globally, ensuring safety and compliance with the Chemical Weapons Convention.
