A Guide to Drinking Tap Water in American Samoa
American Samoa relies almost entirely on local groundwater pumped from wells, while rainwater and surface water sourced from stream intakes are also relied on.
Although most of the country's water supply is treated to some extent, it's perhaps not up to the standards that many visitors are used to. So, can you drink the water in American Samoa?
As a rule of thumb, it is not safe to drink tap water in American Samoa. It is possible to catch traveller’s diarrhoea (a common waterborne form of E.coli) from drinking water that hasn't been fully treated.
But there's no need to panic; if you follow the simple tips in this guide, you’ll be able to have a safe trip to American Samoa while staying hydrated!

4 Ways to Make Sure the Water is Safe to Drink in American Samoa
If you have any doubt about drinking water in American Samoa, follow these tips on making sure the water is safe to drink…
- Boil the water first – boiling water for 10 minutes or longer kills bacteria and is the best way to make sure water is safe to drink.
- Use a Lifestraw Bottle – it includes a filtration system that makes your water safe to drink while also avoiding the use of disposable water bottles.
- Use water purifying tablets – This method comes as little sachets or tablets and, when mixed into your water for a certain amount of time, will kill most bacteria and parasites present in it, making it safe to drink.
- Drink bottled water – Although not super for the environment, buying bottled water from a convenience store or a supermarket is a good way to stay safe.
We elaborate further on these points in the "The Best Ways to Make Sure Water is Safe to Drink" section below.

Is it Easy to Access Safe Drinking Water in American Samoa?
Safe drinking water is not as easy to access in American Samoa as it is in more developed countries. There are no filtered drinking water stations to refill water bottles, and accommodations provide drinking water by merely leaving a couple of water bottles in your room on the first night.
If visitors don't take their own precautions, like using purification bottles, boiling the water or using purification tablets, then they tend to only have bottled water to rely on.
Bottled Water in American Samoa
Bottled water is easily accessible at local supermarkets and convenience stores in American Samoa. Convenience stores can be found across Pago Pago and in almost all villages, so buying bottled water is often the only opportunity to access safe drinking water when you're out and about (unless you follow some of the tips below).
Make sure to dispose of your plastic waste responsibly after use and reuse it whenever possible.

Is the Water Treated in American Samoa?
The public water supply, managed by the American Samoa Power Authority (ASPA), relies almost entirely on local groundwater pumped from wells. Basic treatment processes like chlorination and sediment filters are used. However, the system is susceptible to contamination, saltwater intrusion, bacterial growth and fluctuating water quality due to infrastructure issues and storm impacts.
In short, the treatment facilities for water in American Samoa are rather basic compared to those in more developed countries, so visitors to American Samoa should definitely take precautions before drinking tap water.
Drinking Tap Water in American Samoa
Although most locals are generally fine to drink it, there may be higher concentrations or unfamiliar strains of bacteria, like E.coli, present in the water.
It’s unlikely that visitors will have built up an immunity to particular bacterial strains, which can cause traveller’s diarrhoea.
That's why it is generally advised for visitors to treat the tap water in American Samoa before drinking it, even if the locals are drinking it.

The Best Ways to Make Sure Water is Safe to Drink
As we’ve established, treating drinking water in American Samoa is a good idea for travellers. We understand, however, that there are some challenges when it comes to making sure water is safe to drink, like having access to facilities to boil water or even the environmental implications of buying bottled water.
That's why we have prepared a few ways to purify water so you can put that in your knowledge bank for any tropical adventure!
Boil the Water
Bringing the water to a boil for 10 minutes is probably the best-known method of purifying water. It kills parasites, bacteria and even viruses and ensures that it is fully safe to drink. Plus, it is the cheapest water purifying method out there. Note that boiling water in a kettle won't effectively kill bacteria; water must be boiled for several minutes.

Use Water Purification Tablets
Use your own water bottle, drop a water purifying tablet and “voila!” This method has been trialled and tested for years and despite the fact that it gives a bit of a weird taste to the water, it is widely used by travellers around the globe.
If the taste is an issue for you, try a water-purifying solution. Although a bit more expensive, it offers better taste and water clarity than tablets. Price-wise, this is still going to save you tens of dollars compared to buying bottled water all trip long.
Buy a Water-Purifying Water Bottle
Turn this text into bullet point form for easy reading:
By far our favourite solution of them all, water-purifying bottles like the Lifestraw Bottle removes 99.9999% of waterborne bacteria and 99.9% of waterborne protozoan. That means that there is no boiling necessary and that you can fill up your water bottle from any tap in American Samoa and know that you have a filtration system with you.
While they are not the cheapest option, once the initial purchase is done, all you have to do is replace the filtration cartridge when it expires.
Although there are alternative brands to Lifestraw, this is just the one that the AmericanSamoaPocketGuide.com team use when travelling the Pacific, so we can recommend it with confidence. When looking for alternatives, make sure to search for “water-purifying” and not “water-filtration”, as filtration only improves the taste of the water.
