The NSA is suffering from bad PR. When the folks designed the data center they probably thought who cares about the water use. Well the media has picked up the latest published numbers and spread the word riding the wave of negative PR.
Microsoft was evil at one. Google has the issue. Facebook to an extent and even Apple. The NSA with its large data center has taken over the position of who in the data center industry is most hated by outsiders.
I wonder when Greenpeace will start protesting the NSA.
