Tap Water Safety in Asia
Asia spans the full spectrum of tap water safety. Japan, South Korea, Singapore, and Hong Kong treat water to among the highest standards on Earth, while in most of South and Southeast Asia — India, Thailand, Vietnam, Indonesia — even locals rely on boiled, filtered, or bottled water due to distribution infrastructure that recontaminates treated water before it reaches the tap.
