On Tuesday, August 2, the U.S. Army reported a mustard gas leak at their chemical storage site in Pueblo, Colorado.  They also claim no one has been affected.

Today, August 3, personnel at the site are trying to find out where the leak is coming from.  One official thinks it’s one or two old artillery shells that are leaking.

The Pueblo site is one of five U.S. Army chemical stockpile sites in the United States.  Those sites are in the states of Oregon, Utah, Colorado, Kentucky and Alabama.  A factory designed to destroy the chemical weapons is scheduled for construction in 2013, and it’s hoped it will be ready by 2017.
