Can you drink the tap water in South Korea?

The US Center for Disease Control’s travel advisory confirms the safety of the tap water in South Korea (source). However, it would be best if you take special precautions toward the unregulated water sources in some areas. Like all countries though, water accessibility, sanitation, and treatment vary widely from location to location, so we encourage looking for specific city information.

What do people in South Korea think about the tap water?

South Korea has some of the cleanest tap water in the world, though most locals and visitors drink filtered or purified water from bottles or dispensers. The practice comes from a belief that bottled water is healthier, and the fear that old pipes can contain heavy metals. Filtered or bottled water is served free in most restaurants and machines with free purified hot and cold water are available in most motels, guesthouses and shopping plaza entrances.

What Do People In South Korea Think About The Tap Water?

Travelers and residents of South Korea have rated the water quality and pollution as follows, according to subjective survey data. A score of 100% is considered very high, and a score of 0% is very low. Please be cautious that "moderate to very high" water pollution is bad and the higher the rate of water quality the better.


Always take extra precautions, the water may be safe to drink when it leaves the sewage treatment plant but it may pick up pollutants during its way to your tap. We advise that you ask locals or hotel staff about the water quality. Also, note that different cities have different water mineral contents.
