Mexico's Water Supply

When it comes to tap water in Mexico, it's generally not recommended for you to drink. The quality and safety standards for tap water may not be as stringent as those in your home country or other developed nations. 

Keep in mind that even though some areas may have better-quality tap water due to different treatment methods or water sources, there is still a risk of contamination by harmful bacteria or chemicals. Like the water near Guadalajara (in Zapopan) is considered safe to consume.

Furthermore, it's important to note that you may experience digestive issues due to differences in mineral content or contaminants present in Mexican tap water compared to what you're accustomed to. You can read more here about my go-to medications for stomach sensitivities. 

To ensure your well-being, it's crucial for you to take precautions and be mindful of the water you consume while traveling throughout Mexico. Opting for bottled water or using water purification methods can help you stay safe and healthy during your trip.

Risks Associated with Drinking Tap Water in Mexico

The Danger of Drinking Tap Water in Mexico

When it comes to drinking tap water in Mexico, one of the most significant risks you need to be aware of is the potential for getting sick. 

It's important to remember that even if the water looks clear and tastes fine, it doesn't guarantee that it's free from contaminants. The risk of contamination is present, and consuming tap water without proper treatment or precautions can put your health at stake. 

Common Contaminants Found in Mexican Tap Water

Mexican tap water can contain common contaminants like bacteria (E.coli, salmonella), viruses (hepatitis A, rotavirus), parasites (Giardia, Cryptosporidium), and chemicals (lead, arsenic, fluoride). This is not to say that all water in Mexico contains these.

These contaminants can cause gastrointestinal issues (aka montezuma’s revenge), diarrhea, abdominal cramps, and other health problems. Thus, I suggest avoiding tap water and opting for bottled water or water purification methods during your stay in Mexico.

Avoiding Risks by Drinking Safe Water

To avoid the risks of drinking tap water in Mexico, it's best to stick to bottled or filtered water. Bottled water is easily accessible, but make sure to check for tampering before purchasing. 

Many hotels provide free or affordable filtered or purified drinking water for guests.

Alternatives to Tap Water in Mexico

Overview of Bottled Water Options

If you're traveling in Mexico, you'll want to be sure to have access to clean, safe water. One of the easiest ways to do this is by drinking bottled water. There are a number of different brands and types of bottled water available throughout the country, so it's important to know what you're looking for.

Some popular brands include Bonafont, Ciel, and Electropura. You'll also find mineral water and sparkling water options at most stores such as Oxxo, Kiosko or Seven-11.

How to Ensure Bottled Water is Safe to Drink

As you rely on bottled water for safe drinking in Mexico, it's essential to take a few precautions to ensure its quality. Before opening a bottle, always check the seal and avoid drinking from bottles with broken or tampered seals.

Additionally, be cautious with reusing plastic bottles that may have been exposed to prolonged heat or sunlight, as they can release chemicals into the water. 

Tips for Staying Safe While Drinking Water in Mexico

How to Stay Hydrated While Traveling

Staying hydrated while traveling in Mexico is essential, especially if you plan on spending time outdoors or doing physical activities like hiking or swimming. To ensure you have access to clean drinking water throughout your trip, consider purchasing larger bottles of water and also bringing a portable hydration like a Camelbak backpack.

Another great way to stay hydrated while avoiding questionable tap or bottled water is by consuming fresh fruits and vegetables that have high water content like cucumbers, tomatoes, and melons. Just make sure they are thoroughly washed with clean water before eating.

Overall, taking precautions when it comes to drinking water while traveling in Mexico can go a long way in keeping you healthy. 


To stay healthy while drinking water in Mexico, it's essential for you to take necessary precautions. Be aware of the potential risks linked to tap water and choose bottled water or properly filtered/boiled tap water. 

Just like at home, check the bottle seal to ensure it hasn't been tampered with and avoid purchasing from street vendors or untrusted sources.

By staying informed and prepared, you can fully enjoy your time in Mexico without concerns about falling ill from contaminated water.
