DUGWAY, UT - AUGUST 15: Workers walk past filtration stacks at the small item decontamination testing chamber facility at the U.S. Army's Dugway Proving Ground on August 15, 2017 in Dugway, Utah. Workers at this facility handle some of the most deadly and dangerous biological and chemical agents on earth. The 800,000-acre base in the middle of the Utah desert is a top secret facility that tests and develops defensive measures to counter the effects of biological and chemical agents that may be used against the United States.
