This infographic, which cites research from the Centers for Disease Control and Prevention (CDC), indicates only the U.S. and Canada along with western Europe, Japan, and Australia have tap water that’s considered safe for drinking.

According to the organization WaterAid, more than 650 million people around the world have no access to safe drinking water, and 900 children die every day because of digestive issues from unclean water and poor sanitation.

While it’s true that things could be much worse for Americans, we must continue to be vigilant about water quality.
