"This policy seeks to ensure that the Department of Defense has taken adequate measures to plan, prepare and provide for an adequate water supply to meet mission needs," the memo said.

The study will be used to identify which bases are most vulnerable to water shortages, said John Conger, assistant secretary of defense for energy, installations and environment. "What I'm really trying to find is... which [bases] are heading for a train wreck," he said, "and where they are heading for trouble, how we can slow that train down."
