The U.S. Army says it has finished work containing a leak of mustard agent at the Pueblo Chemical Depot.
The leak was discovered in August by a sensor at one of the "igloos" containing the deadly toxin. The Army then sorted through the stored projectiles and found one leaking liquid mustard and one leaking mustard vapor.
The Army said Monday that the leaky projectiles were moved to a more secure igloo on Nov. 5. No one was hurt.
The Army is currently in talks with Colorado health officials to settle a state lawsuit calling for increased monitoring of how chemical weapons are stored. Congress has set a 2017 deadline to have the weapons destroyed to meet international treaty obligations.
