What are the risks of drinking tap water?

Dr. Michael Roizen, MD
Internal Medicine
While your tap water may be potable, that doesn't mean it's pure or healthy. A lot of people can get low-grade infections from bacteria in local water supply-and that can lead to such symptoms as feeling bloated, itchy eyes, stomach cramping, and fatigue. And you'd have no idea what even caused the problems.

You don't need to blow your 401(k) on bottled water, but it's a smart idea to use a water filter for any drinking water you use out of the faucet.
