The US military has created at least 31,487 toxic sites at 4,624 military facilities or properties. Many of these have been cleaned up to some degree over the past few decades, but 7,056 still haven't had any cleanup, nor is there an accepted cleanup plan in place, according to the Sept. 18, 2008, testimony of Wayne Arny (703-695-2880), Deputy Under Secretary of Defense, before the Senate Environment & Public Works Committee.
