The New York Times recently published an article about the latest health craze for "raw water", unfiltered, untreated, unsterilized spring water. Apparently people are rushing to get off the grid and drink water that hasn't been treated.
Luckily the Washington Post came to the rescue and published another article describing the risks and folly of this latest water craze, quoting our CDC collaborator Vince Hill. The comments on the NYT piece are also worth a read.
Every time I get off an airplane from a trip to a lower-income country the first thing I do is head to the drinking fountain and enjoy the incredible luxury of having clean water come directly out of the tap. Increases in life expectancy in the U.S. can largely be attributed to provision of clean water-- read a great popular article about it here, or an academic article here. Of course there are many issues with our nation's water systems, but having systems designed to remove pathogens is not one of them.
