I could not tell you - exactly what the US Government has. Surely we must have the capability to do this. But who exactly in the military does this - and how - I am not sure. Using Navy ships might be one smart way to purify water. Especially for Puerto Rico.

I helped at a flooding disaster in Africa (Mozambique disaster, early 2000's). I saw a team in action there - from Austria. They are a military team, but organized more to provide humanitarian assistance. They are especially good at things like purifying water. They have ALL the gear ... big purifying units, hoses, tubes, all the connections. They go right into a polluted area, and start producing pure water for poor people. It's very impressive to watch. These folks would be a HUGE help to Puerto Rico right now.
