At first glance this map doesn’t look all too accurate since in many of these countries (or at least certain cities within them) tap water is considered drinkable. But as the Centers for Disease Control and Prevention points out, although water may be compliant as drinkable by law, that doesn’t necessarily mean it’s good for you. Water that is legal might still have pollutants at higher than healthy levels plus local governments don’t take into consideration visitors who don’t have immunity to regional bacteria and microbes. It might take more than a few glasses resulting in frequent toilet trips before you get used to the H2O so if you’re on a shorter trip, it’s best to avoid the tap water in any country not colored blue on the maps above.
