I'm sure you've asked this when traveling， "Can I drink the tap water？" It is easy to get confused about where it's safe to drink and where it's not， especially if you're planning a multi-destination trip． Some countries like India and Mexico are well known for unsafe tap water but where else is it a health risk？
If you want a quick reference for where on the Earth the water is safe， we've got you covered with this helpful graph（图表）． It was created by Just the Flight． All of the information about water safety is based on data from the CDC． The graph also shows pricing for bottled water and beer for each country as well!
Have plans to travel to a place where the tap water is deemed（认定的） unsafe？ Remember to skip ice in your drinks and avoid uncooked fruit and vegetables unless they've been peeled（削皮）． Make sure to use bottled water when brushing your teeth as well．
Please know that not all of the countries listed on the graph have dirty or polluted water． I know from personal experience： tap water may be safe at different elevations（海拔）and in different areas within a country shown as unsafe on the graph． Finally， further research is required． However， if you fall short of that， you'd better follow the advice on the graph to avoid an uncomfortable case of traveler's illness．
It's definitely better to be safe than sorry!
