You’re on vacation. It’s hot, you’re tired, and your hotel sink looks perfectly clean. So you fill a glass with tap water. But should you drink it?
In many parts of the world, the answer is a resounding no. Drinking tap water while traveling can sometimes lead to serious health issues, even if it looks and smells fine. Not all water is created equal, and what your body is used to back home may not be the same as what flows from the tap abroad. It’s a potential risk that every traveler should be aware of.
Here’s why tap water is not always safe to drink when you travel and how to know when it is. Following local guidelines and recommendations is crucial, as they are designed to keep you safe and healthy during your travels.
Water Quality Isn’t the Same Everywhere
The water from your faucet in New York City is treated very differently from that in a rural village in Southeast Asia or some popular European destinations. It’s important to note that fewer than 100 countries consistently meet the safety standards required for drinking water, highlighting the significant disparity in tap water quality.
In many regions, water may be untreated, poorly filtered, or piped through old, corroded infrastructure that adds contaminants. In some areas, especially where the climate is hot, and water storage systems are outdated, bacteria can easily grow in tanks and pipes.
Even locals in some countries often boil their water before using it or rely entirely on bottled and filtered sources. If that’s what the residents are doing, tourists should take note and follow their lead.
What Are the Risks?
Drinking contaminated tap water abroad can expose you to various harmful microorganisms. These include:
- E. coli
- Giardia
- Salmonella
- Hepatitis A
These pathogens can enter your body through a single glass of unfiltered water and may cause anything from mild stomach discomfort to severe, prolonged illness. One of the most common issues travelers face is “traveler’s diarrhea,” which can be not only unpleasant but also dangerous if untreated. In more serious cases, contaminated water can lead to hospital stays or long-term health problems, underscoring the potential risks of drinking contaminated water.
Even “Safe” Water Can Affect You
Some countries are known for having safe tap water, but that does not guarantee your body will handle it well. Water can contain natural minerals, bacteria, and microbes that local people are used to, but your digestive system is not. That means you might still get sick from drinking water that is technically clean by local standards.
This can happen even if you only brush your teeth with local water, rinse fruit, or drink something with ice made from the tap. These small exposures can still affect travelers with sensitive stomachs.
Red Flags to Watch For
Here are some signs that you should avoid drinking the tap water at your destination:
- Signs near sinks that say “non-potable” or “do not drink.”
- Water that smells bad, tastes strange, or looks cloudy
- Visible rust on pipes or water tanks, especially if they are located on rooftops
- Widespread local use of bottled water, even in hospitals or government buildings
When you see bottled water sold in hotel lobbies, at local clinics, or even by street vendors near public restrooms, it is usually a good sign that the local tap water is unsafe to drink.
Countries Where Tap Water Is Safe
Fortunately, there are many places where tap water is safer and cleaner than bottled water. Countries with some of the best drinking water include:
- Switzerland
- Japan
- Singapore
- Iceland
- New Zealand
- Canada
- Germany
- Norway
- Austria
- Finland
In these countries, you can confidently refill your bottle from public fountains or the bathroom sink without concern. Their water systems are modern, heavily regulated, and well-maintained.
How to Stay Safe
When traveling to a country where water safety is questionable, follow these tips:
- Stick to sealed bottled water
- Use bottled water for brushing your teeth
- Avoid ice unless you are sure it was made from filtered water
- Wash fruits and vegetables with bottled water
- Consider carrying a portable water filter or purification tablets
These precautions might seem excessive initially, but they are worth it if they help you avoid getting sick on your trip.
Conclusion
Water is essential, but not all water is safe to drink worldwide. Tap water quality varies widely depending on infrastructure, regulation, and climate. Just because it looks clean does not mean it is free of bacteria or harmful microbes. Every traveler should be mindful of this.
Before drinking from the tap in another country, always check local guidelines. When in doubt, bottled water is always the safer choice. After all, getting sick on vacation is never part of the itinerary, reinforcing the importance of being cautious about tap water when traveling.
