The Truth About Drinking Water Abroad: A Guide to Staying Safe on Your Next Vacation
The Hidden Dangers of Tap Water and Ice
Imagine sipping a refreshing margarita on a Mexican beach, only to realize the ice might have been made with tap water. Or brushing your teeth in Bali, accidentally swallowing a drop of water that could be contaminated. These scenarios are more common than you think, and they can turn your dream vacation into a nightmare.
According to the Centers for Disease Control and Prevention, up to 70% of international travelers suffer from diarrhea, with contaminated water being the leading cause. Yet, fear often overshadows the facts, leaving tourists paralyzed by anxiety. So, what's the real deal with drinking water abroad?
The Fear Factor
Many travelers are afraid of drinking tainted water, and it's not hard to understand why. When Jane Angelich checks into luxury resorts, she interrogates staff about filtration systems, brushes her teeth with bottled water, and skips ice and salads. Her caution is not paranoia but a pattern recognition of the risks.
For instance, Mexico City loses 40% of its piped water to leaks, inviting bacteria, viruses, heavy metals, and chemicals into the supply. As Paul Conolly, managing director of Water-to-Go North America, notes, even locals don't drink tap water.
The Bottled Water Conundrum
Buying bottled water is a popular fix, but experts warn that it's not a foolproof solution. Counterfeit seals, made with glue or wax, are rampant in destinations like Bali and the Dominican Republic. Shanina Knighton, a nurse, regularly inspects each cap carefully and avoids drinking if the seal looks suspicious.
However, using bottled water creates ecological nightmares. Producing one liter of bottled water requires three liters of water and emits 600 times more carbon dioxide than tap water, according to the Pacific Institute.
The Filter Factor
Travelers like Cynthia O'Leary swear by water filters, even packing pitchers in their checked luggage. Filters can help remove some impurities, but they're not perfect. As O'Leary notes, filters sometimes only remove chemical contaminants, leaving travelers vulnerable to viruses that require boiling or UV sterilization.
Expert-Approved Resources
To navigate the murky waters of water safety, travelers now have clearer options. Here are four vetted resources that deliver life-saving clarity:
CDC Travel Health Notices
- The government's health notices are the gold standard for U.S. travelers. Updated weekly, they detail pathogen risks, chemical hazards, and region-specific precautions.
- Use it for quick, government-vetted 'do/don't' drinking rules.
UN SDG Water Data Portal
- The United Nations' online portal offers real-time national water safety grades, tracking progress on clean water access, treatment infrastructure, and contamination risks.
- Use it to gauge a country's overall water security credibility.
Yale Environmental Performance Index
- The university scores 180 countries on ecosystem health, ranking nations on drinking water quality, sanitation, and heavy metal pollution.
- Use it to compare destinations' environmental stewardship, including water.
Local Utility Reports
- Hyperlocal, granular water testing data. Search for city-specific reports to find neighborhood-level contaminants often overlooked by national averages.
- Use it to check lead levels or treatment disruptions in your area.
Know Before You Go
The best water quality advice involves timing. Experts say you should think about water quality well in advance of your trip. If you're at risk, make arrangements to have access to plenty of clean water at your destination.
As David Dyjack, CEO of the National Environmental Health Association, says, 'Knowing your risk gives you an advantage before heading to the airport.'
My Bali Experience
I checked into a vacation rental in Canggu, Bali, where drinking the water was a no-no. Our host provided drinking water, but old habits die hard. One evening, I brushed my teeth with tap water and swallowed some, waiting for stomach cramps and the urgent call of nature.
It never came. I didn't end up with Bali Belly, but I could have. It was a lesson learned: water safety requires round-the-clock vigilance. Let your guard down even once, and you could end up in the hospital.
The Controversy and Your Voice
Water safety anxiety is a constant companion for international travelers. But is the fear justified, or are we overreacting?
- Do you trust bottled water abroad, or have you encountered 'resealed' bottles that made you suspicious?
- What's your go-to strategy for water safety: filters, UV lights, or sticking to beer and wine?
- Have you ever let your guard down and paid the price?
The Hidden Risks
- The Ice Cube Trap: Freezing does not kill bacteria. That frozen margarita or iced soda can transmit the same pathogens as tap water.
- Counterfeit Bottles: Vendors refill bottles with tap water and reseal them with glue or wax. A sealed bottle isn't always safe.
- The Toothbrush Reflex: Muscle memory is dangerous. Rinsing your mouth with tap water out of habit puts you at risk of ingesting pathogens.
Stay Informed, Stay Safe
By using the vetted resources and adopting safe habits, you can stay informed and safe while traveling. Remember, knowledge is power, and staying vigilant is crucial to avoiding water-related health issues.
