The 25 U.S. Cities with the Best Drinking Water

Tap water gets a bum rap. Sure, there are some places where maintenance and government failure or negligence has made drinking water dangerous (see: Flint, Michigan), but the tap water in most cities is perfectly fine. In fact, with exacting quality control and state-of-the-art filtration systems, you'll find that it's just as good as the stuff you'd normally get in a plastic bottle.

That's especially the case with the water in these 25 locales. That's right: we've dug into the data and ranked the 25 cities in America (out of the 200 biggest) with the cleanest drinking water. So read on, and stay hydrated! And for a list containing the flip-side, here are the 25 cities in America where you might want to consider drinking bottled water, after all.

Our Methodology: Our data includes areas with the lowest "pollution potential," provided by the Environmental Protection Agency; the lowest number of contaminants in the local water, according to the Environmental Working Group; and the annual American Water Works Association's "Best of the Best" drinking water taste tests (determined by water experts and industry leaders). Note: A city doesn't have to source its water from a natural spring or pristine river to have great drinking water, but it does have to have to taste good and have low levels of contaminants.
