I'm from Chile and we drink tap water without boiling. Some people buy filtered water because they dont like the taste, not because is unsafe.

It shocked me when I visited Peru and Mexico and realized that tap water is not safe there.

In Canada most people drink water after filtering through a Brita, but it's safe to drink without.

Belgium: yes! We drink tap water. Straight from the tap. Hardness varies from city to city. At my home I have a filter to make the water softer. That helps the taste but also keeps all faucets etc running.

Croatia here,

tap water is completely drinkable and safe without any boiling. Exception are some more remote islands, so if you are going on some island, chekc if the tap water is drinkable.

Fun fact: Croatia actually uses drinkable water for toilets as well, altough i would not drink from a toilet :)

in Brazil de usually dont boil, but use a traditonal ceramic pot filter.

In the UK they had separate taps for hot and cold because the cold was safe to drink and the hot was not.

From Singapore. Tap water here is potable but we boil it first out of habit. (But I use tap water for drinking when boiled water has run out).

We drink straight from the tap here in Scotland. It's great water.

Austria, yes, water is fine like that I would even drink it in the shower without issue. What is an issue is this habit once made for a bad time in Egypt where I didn‘t drink tap water (I was warned), but I mindlessly used it for brushing teeth and that probably ruined my last few days there.

India here. I can drink tap water without boiling, it just has a slight chlorinated taste. That's why we prefer to filter it, rather than boil.

Luxembourg here, i'll drink straight from the tap.

The US varies widely. Some Americans in this thread tell you their tap water is squeaky clean. Meanwhile, there are places like Flint where the tap water not only is deadly but remains deadly even if you do boil it.

German: Yes. Most of the water I consume comes straight from the tap

I never drink water out of the tap because I prefer to filter it first. It’s safe to drink but I want it clean and much colder so into a filter pitcher and put that in the fridge

Generally in the west (US/Canada, and most of Europe) tap water is safe to drink. I've been to Iceland and don't remember tap water being a concern. This is something you should double check before every trip though. A good rule of thumb is just going by how developed/rich the country is that you are visiting, with more developed countries usually having potable tap water but this is not a guarantee. (And some countries are far too large and diverse to apply this rule efficiently)

Also asking the locals is not necessarily a good idea either as there immune system might be accustomed to the different bacteria and pollutants in the water. For example drinking tap water in some places in the Middle-East might not be an issue for the locals but as I haven't grown up there I probably wouldn't risk drinking tap if I can avoid it, not to ruin the trip with getting sick.

TLDR: check with your country's official travel recommendations

Edit: someone mentioned bottleded water just being bottled tap water. While this is not uncommon in Europe (not sure about the rest of the world), the water does go through extra steps of filtering and cleaning meaning it might be a bit safer to foreigners.

Norway = Yes. But the fresh water pipes are in the same trench as the sewer pipes, and being 100 years old, the clean water depends on the pressure. This is in Oslo btw..

Semi-rural American here. Our water comes from a well and is safe to drink. However, it is hard water and we often prefer to either use a purifier or buy purified water for drinking directly.

Venice: we filter it first via some cheal filters. It is very common to own a water mug with a filter embedded here.

Paris: directly from the tap water, though I don't like the taste.

I'm from Denmark, and water is safe to drink straight from the tap here.

Im from Newfoundland Canada. The city I live in has a water treatment facility and the tap water is perfectly fine to drink without any filtering or boiling.

Many smaller towns in my province only have natural water sources (lakes/ponds/streams) or wells for their water supply. The town I grew up in was like that up till about 2005-2006ish. It was pretty rare for us to have to boil water though, maybe 3 weeks out of the whole year, a neighboring town with a different water supply had to boil their water for most of the year so there was alot of variability.

No, I never drank unfiltered tap water. I have always lived in areas with poor-tasting tap water. It's not necessarily dangerous, but has a high calcium content and isn't the cleanest either.

As a kid, we had a carbon filter on our refrigerator, and that was good enough. When I moved out of my parents house, I started getting those 5 gallon bottles and would refill them at the grocery store.

I eventually got my own refrigerator that had a carbon filter, but I couldn't really go back to a carbon filter once I got used to water filtered by a RO system. It just didn't taste very good. So about a month ago I installed a RO filter under my sink, and now I don't need to drag my bottles to the store anymore. Best of both worlds!

Hungarian here. It is safe to drink without boiling. People only boil water for baby formula to be extra safe.

Quebec, Canada. I grew up in a rural area where we had our own artesian well on the plot of land, so not attached to any city infrastructure, and no purification process at all, except what is done naturally from the soil. And guess what? It's the purest water I've ever seen, it taste amazingly fresh and the tap is directly plugged on it.

Moved to a big city and now have to use the city infrastructure, which of course have a huge purification plant and they do tests continuously to make sure it pass a high quality threshold. But even if it's probably cleaner than 90% of the rest if the world, it still have a slight unpleasant taste. I could probably buy a filter, but never bothered.

Buying bottled water is seen as wasteful and also a scam since it's often just tap water they bottled. When my family visited a country where bttled water is common, they were disgusted at how much plastic pollution it creates.

I would hate to have to boil water before every usage, I assume you always keep a few gallons in the fridge to keep some cold? It takes space and energy to prepare, must be annoying. But what I wonder the most is, how to do wash yourselves and your clothes? If the water smells foul, doesn't taking a shower just stink you even more than it cleans?

Even better, I do not boil I run though and store in a Brita pitcher that should have had a filter change six months ago!

Moscow, Russia. You can usually drink tap water in Moscow, but it's something unusually good for Russian bigger cities in general, and it's considered a good thing to boil it. Actually depends on local specifics and where the water comes from.

Yes, living in the US, it's safe to assume that any tap water is safe to drink without boiling. Sometimes it doesn't taste great because of mineral content, but it's safe with very few exceptions.

That's also been the case in any developed country that I have visited, including Iceland, Canada, pretty much all of Europe, Japan, Korea, Taiwan, Singapore, etc. There may be exceptions in all of those places, but in any large city in a developed country you can drink the tap water.

Just ask someone from there on day one. They can obviously tell and i think this is the best strategy. I bet it's safe like in most parts of middle and northern europe.

In Argentina, generally you can drink straight from the tap.

In Malaysia, the water is advertised as safe to drink. Large majority however, either boils it or uses their own water filters.

You can drink the tap water in most places in Iceland without boiling it (especially in Reykjavik), but if you're further into the countryside then I would check first!
