You need drinking water no matter where you go, but not all parts of the world can always guarantee clean, safe tap water. This handy guide shows you where drinking from the tap is OK, and where you're better off doing further research on the subject.
The guide from Danny Ashton at NeoMam Studios uses information gathered from theUnited States Centres for Disease Control and Prevention. You can see each continent with guaranteed safe countries in blue and potentially unsafe countries in brown, along with some tips for how you can avoid unsafe water. Keep in mind, potentially unsafe means that it could be harmful to drink if your system is not used to that environment, not necessarily that the water is polluted and dirty.
