For context, I live in Hong Kong where most people drink tap water after boiling first. Some may install water filter but may still boil the water. Very few drink bottle water unless they're outside and too lazy to bring their own bottles.

Now, I'm researching whether I can drink tap water in Iceland (I'm going there in August), and while it looks like the answer is affirmative, almost no web article mention whether I need to boil the water first. People in Japan (a country I've visited a few times) also seems to be used to drink tap water directly without boiling.

The further I searched, the more it seems to me that in developed countries (like US, Canada and the above examples), tap water is safe to drink directly. Is that true? Do you drink tap water without boiling?

It sounds like a stupid question but I just can't believe what I saw. I think I experienced a cultural shock.

Edit: wow, thanks so much for the responses and sorry if I didnt reply to each one of you but I'll upvote as much as as I can. Never thought so many would reply and Lemmy is a really great community.

2nd Edit: So in conclusion, people from everywhere basically just drink water straight out of tap. And to my surprise, I checked the Water Supplies Department website and notice it asserts that tap water in Hong Kong is potable, like many well-developed countries and regions.

However, as the majority of Hong Kong people are living in high-rise buildings, a small amount of residual chlorine is maintained in the water to keep it free from bacterial infection during its journey in the distribution system. Therefore it is recommended to boil the water so that chlorine dissipates.

So, in short, I actually do not need to boil the water unless I hate chlorine smell and taste. But I guess I'll just continue this old habit/tradition as there's no harm in doing so.

Australian here, no need to boil tap water for us. Some people get filter taps installed but regular tap is fine for most of us plebs

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.

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 :)

New Zealand, we drink it from the tap although some claim to dislike it depending on which part of the country your in, personally I think they're a bit too fussy

[–] [email protected] 5 points 1 year ago

I'm from πŸ‡΅πŸ‡­, particularly Davao City (southern part of the country).

Tap water is drinkable here although there are water bottles available.

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.

[–] pakiyimo 5 points 1 year ago

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

[–] [email protected] 5 points 1 year ago

In NZ, the only time I've boiled water is when we had an earthquake that screwed up a bunch of stuff, including the water & sewage pipes.

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.

I’m located in the US and like others have said it’s safe to drink the tap water, but me personally, I run my water through a filter first.

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.

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

[–] [email protected] 5 points 1 year ago

I’ve never boiled tap. It’s safe where I live. I do have a reverse osmosis filter though. But only for taste, and to remove hardness to protect my glassware.

[–] [email protected] 5 points 1 year ago

In England we drink straight from the tap. I live in London which has incredibly hard water so it's not the nicest tasting and it will leave white residue on the glass but it's not bad for you.

[–] [email protected] 5 points 1 year ago (1 children)

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

[–] [email protected] 4 points 1 year ago (1 children)

you forgot the part where you add an unsafe deathly electrical wire to it to get warm water, lmao.

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

Australia: We don't boil tap water here in Australia.

Rural California here. We are on a well and drink from the tap. It gets a mineral taste and smell in the warmer months. Much better tasting then the chlorinated water when we lived in town though.

[–] [email protected] 5 points 1 year ago

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 it depends on where you live. I grew up and live now in upstate NY and the tap water is great. In between I lived in Arizona and the water was terrible. I have at different times a water cooler or an undersink reverse osmosis. The water wouldn't make you sick though so you can drink it if needed, it was just very hard and tasted bad.

[–] setsneedtofeed 4 points 1 year ago* (last edited 1 year ago)

Reverse osmosis was the right call.

The thing about possible problems with municipal water in the US is that boiling would make the water worse. Boiling kills bacteria, but for things like PFAS contamination all boiling would do is steam off water and increase the concentration of contamination in what’s left.

I’m somewhat paranoid about PFAS contamination since it is tasteless and more of a long term problem rather than something that makes people acutely sick. There are entire counties where I refuse to drink or eat anything prepared within them because of their histories with industrial contamination entering the water supply, which is usually revealed to the public long after the fact.

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

[–] [email protected] 5 points 1 year ago

In France tap water is drinkable and good almost anywhere, the exceptions being in some cities during drought or due to unusual pollution. I actually dislike most mineral bottled water because I find it tastes like something.

I used to live in Thailand, while the authorities say the water is good you'll likely get sick if you drink water straight from the tap. I used to buy my water from a filtering machine near my condo.

[–] [email protected] 5 points 1 year ago

In Finland I drink straight out the shower head, it's fun and wonderfully safe.

[–] [email protected] 5 points 1 year ago

We filter our tap water here in Korea. Most people do, but as I understand, it's safe to drink it just straight from the tap. It's just better through a machine that gets rid of any lingering chlorine and heats it or chills it for you.

[–] [email protected] 5 points 1 year ago

Most first world countries will issue boil warnings when there may be a necessary reason. Ie) water main work or other contamination.

Iceland should be fine. In fact, I think they have some of the cleanest water around.

[–] [email protected] 5 points 1 year ago (1 children)

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.

Toronto tap water is actually very, very good. Tastes better than most bottled water I've tried. Very high standards here - we are extremely fortunate and I hope the high standards stay for a long, long time.

[–] [email protected] 4 points 1 year ago

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

[–] ki77erb 4 points 1 year ago

I'm in the US. When I was kid playing outside we would drink the water straight out of the garden hose. (Yeah I know that's the same as "the tap"). Now days, we have a filter on the water dispenser built into the refrigerator. So water and ice goes through activated charcoal to remove anything that could be in it.

I live in the USA, and we don't have to boil tap water in my city, but after having lived for a spell in a place where tap water is boiled first, I boil mine because I like the way it tastes--it's sweeter. Maybe boiling it helps get rid of the chlorine taste that city water has? I don't know. But I do prefer it.

I lived in Taiwan and was taught to boil. I'm starting to think you probably don't need to but we just grew up not knowing any better. In Australia you don't. I drink out of any tap that's not a rain water tap. Lots of Asians here still buy bottled water or boil water out regardless. So it seems to be out of uninformed fear or habit.

My belief is unless a local government/health authority tells you you can't drink straight from the tap. I'm inclined to believe it's safe.

[–] [email protected] 4 points 1 year ago

Seems like boiling water is a tradition is Asia/Chinese region.

[–] [email protected] 4 points 1 year ago

In Canada I don't boil it.

In Vietnam, I do. Although more because I'm always making tea than anything else. Unless it's well water, in which case that's only for doing dishes, I won't drink that.

I did nearly die from cholera some years back, but it was probably not from the tap water specifically. Sanitation and food safety has really improved here in the last decade, I'm happy to say.
