I've lived in Milan (Italy) London (UK) and Rethymno (Greece) tap water is safe to drink in all of them, extremely good in Milan just straight up, good in London but with a lot of limescale so we filtered it for taste reasons, and the same as London in Rethymno.

US. The tap water is safe to drink. Occasionally a metro area will have problems and issue a boil order, telling people to boil tap water before drinking, but this is rare. Some areas have problems with lead contamination due to aging infrastructure, but this too is uncommon in the modern day.

Yes of course it's safe. I drink filtered water from our fridge, but tap is perfectly fine too. I'm from Europe btw.

Yep, in the Netherlands we drink tap water all the time. No reason to boil it, except for tea of coffee of course.

No boiling, but I bought a filter after listening to a story about PFAS.

Sweden. Very good water here, people drink from tap.

Austria here, I drink tap water without boiling all the time without thinking twice about it. Pretty much in the entire EU I feel safe doing so.

Australia here, yes most people drink it without boiling but it depends a little what region you’re in. Some bits of the fat north or some island towns, you may be better off boiling it. Lots of people in the city use built in filter taps but I kind of write that off as con job.

Acc. to this site it's fine to drink cold water without boiling in Iceland. However don't drink the tap warm water - it's sulphurous.

But answering your question, in Brazil it varies from city to city. I drink tap water in my city just fine, without boiling or filtering; but I had to do both in another city ~400km from here.

Illinois, US. tap water has always been safe to drink wherever I've lived in this state. I've only been under a boil order a couple times in my life. That being said, I do filter my tap water otherwise it tastes strange to me

I live in a major Italian city, I'm well over fifty, and I've always drunk unfiltered water straight from the tap without boiling. Some Italians apparently don't like the taste of tap water but it's still safe to drink it unfiltered and unboiled in nearly all the country.

Some Spanish cities: In Madrid, people drink tap water without boiling. Some leave it to rest so the slight chlorine smell leaves the water. In Barcelona and Valencia, being coastal cities with desalinators, their water is too "heavy" (has too high a density of minerals), which makes it unhealthy to consume on a regular basis, and boiling it does nothing, so people buy a lot of bottled water.

I'm in Canada and we drink from the tap.

I live in South Florida. The tap water in my area is safe. I drink it without boiling or filtering.

Spainiard here. You can drink tap water everywhere (that's connected to the drinking water network, obviously), but there are better tasting waters than others. Madrid's water is bad, Barcelona's is atrocious (I don't know anyone living there that doesn't buy bottled water, it even gives weird flavours when cooking), but other places are nicer. My town's water is awesome, I just fill up bottles from the tap and put them in the fridge for easy cold water and laugh at the camacus.

Australia- Safe to drink. The water is chlorinated and fluoridated (for dental health).

I'm not 100% sure if the water is fluoridated across the whole country or just in my state

Depends on how acclimated your stomach is. Locals may be able to drink without problem but foreigners may have stomach problems.

In the United States, it is a little bit different.

There are "standards" that water quality has to live up to. Do these standards actually meet the criteria for safe drinkable tap water? Not always. This is evident in places like Flint, Michigan and other poorer urban areas.

Some of the tap water can be so bad that people wouldn't dare to drink it even after boiling.

In some areas, the tap water quality is wonderful.

Here is a relatively decent source about the topic as it pertains to the USA. https://wisevoter.com/state-rankings/best-tap-water-in-the-us/#:~:text=The%20ten%20states%20with%20the,%2C%20South%20Dakota%2C%20and%20Nevada.

The long story short here, is certain places like Hawaii have extremely clean tap. Other places, like Texas, are notorious for having numerous water quality violations.

It falls down to each individual State and City for maintaining the standards that were set. In my opinion, it it just an easy way for them to waive liability at the end of the day.

Finland has all around signs for foreigners that the tap water is not only drinkable, but very high quality. https://yle.fi/a/3-10303369

But for some unfathomable reason, maybe to push more expensive drinks, many restaurants charge for tap water. Except they do not tell it in advance, you just get surprised by it on the bill and swear never to go that place again.

I am in Japan and have no issues with tap water here, used to drink it regularly.

I live closer to Mt. Fuji now and go get spring water from the mountain weekly instead. There's a basin at a shrine nearby that collects it and is free for people to take. No issues with the tap water, but this water tastes a lot better.

Spaniard here. I've been drinking unboiled tap water since I was a kid. It's perfectly safe to do that.

Finnish here and the tap water here is one of the cleanest in the world, so yeah, I drink straight from the tap.

In Brazil we usually haver ceramic filters attached to our faucets, so we drink water from there.

I live in Ecuador. Tap water can be drunk without boiling on the capital and most other cities in the andes. In the Amazon and the pacific is better to boil it first. Guayaquil the second largest city has a reputation of having incredibly dangerous water

Here in Brazil, you better boil everything. Yet it's still dangerous in some places.

France : we drink tap water directly without any issue. People who drink bottled water is because they dislike the taste of tap water where they live.

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.

nyc us here, only boil water if there is a warning due to a pipe break or something.

northern USA and we have some of the cleanest tap water in the country. Drink it all day from the tap you will never get sick from it, just tastes like nice water.

I wouldn't call US a developed country

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!

The thing about living in an undeveloped countries is that you don't have to worry about that sort of thing.. I'm pretty fucking sure a billion things will get me before contaminates water does.

Switzerland here,

Yes we absolutely drink tap water here, not only it is well regulated but it may also beat many bottled water in terms of taste..

Here is Jamaica it is safe to drink the tap water without boiling.

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.

Australian here, I grew up drinking tap water without boiling it but since I married my wife who is Chinese, I must drink it after it was boiled. It's good for the healthy.
