Can you drink the tap water in Mexico?
The US Center for Disease Control's travel advisory recommends avoiding tap water and drinking bottled or disinfected water in Mexico (source). 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 Mexico think about the tap water?
Tap water in Mexico is mostly not safe to drink. Purified water in plastic bottles is sold everywhere and is also available from large dispensers in some accommodations. The most effective means of water purification is vigorous boiling for one minute (three minutes at altitudes over 2000m). Another option is a SteriPen (www.steripen.com), which kills 99.9% of bacteria and viruses with ultraviolet light. Pregnant women and those with a history of thyroid disease should not drink iodinated water.
Non alcoholic beverages:Tap water is potable, but generally not recommended for drinking. Some exaggerated people even claim that tap water is not good for brushing teeth. Hotels usually give guests one (large) bottle of drinking water per room per night. Bottled water is also readily available in supermarkets and at tourist attractions. Another drink is called Chamaica it is Hibisicus juice.
Some parts of Mexico are known for travellers' diarrhea that it is often called "Montezuma's Revenge" (Venganza de Moctezuma). The reason for this is not so much the spicy food but the contamination of the water supply in some of the poorer zones in Mexico. In most of the small towns that are less industrialized, only the poorest Mexicans will drink tap water. The best policy is to only drink bottled or purified water, both of which are readily available. Be sure to specify bottled water in restaurants and avoid ice (which is often not made from purified water) in non-alcohol drinks. Just like in the USA, in most major Mexican cities the water is purified at the cities' water company. In most restaurants in these poor zones, the only water served comes from large jugs of purified water. If you get sick, visit your local clinic as soon as possible. There is medicine available that will counter the bacteria.
What Do People In Mexico Think About The Tap Water?
Travelers and residents of Mexico 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.
