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.

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.

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.

I live in the US in a location where the tap water is safe to drink (not always the case, e.g., Flint Michigan) but I still filter it for the taste (chlorine in the water).

Most municipal water is safe to drink in the US. Ground water depends entirely on where you live and many situational factors (City pollution, water level, etc.).

We will get boil notices from time to time when a contaminant is detected in the water supply. But that's been rare in my experience, after living in several regions in the US.

No one should ever use tap water for netty potting without boiling it though! You can contract a brain-eating amoeba if you don't boil, which has over 97% death rate.

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..

[–] mokosai@lemmy.world 3 points 2 years ago

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.

US, tap water is perfectly good to drink.

Having visited Iceland a few years ago, Iceland's tap water is the best tasting water I've ever had anywhere. Please take this opportunity to try it while you're there.

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

[–] YellowmanfromMoon@lemmy.ml 3 points 2 years ago

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

[–] mintyfrog@lemmy.ml 2 points 2 years ago (2 children)

In USA yes, we drink tap water without boiling as long as we're in an area with safe tap water (most of the population) and not using our own untreated/untested well water. Every once in a while we get alerted to local unsafe tap water. We have a filter on the tap water but haven't always.

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 didnβ€˜t drink tap water (I was warned), but I mindlessly used it for brushing teeth and that probably ruined my last few days there.

[–] computerfan0@beehaw.org 2 points 2 years ago

Irish person here. Yes, I drink my tap water without boiling. My water comes from a well as I live in a rural area, but town/city water is drinkable too.

[–] BendyLemmy@lemmy.ml 2 points 2 years ago* (last edited 2 years ago)

This is crazy - for sure, in many countries it can be taken straight from the tap depending on the reliability of infrastructure... but to waste energy boiling it??? No thanks.

In England, I moved a few times - some places have great tasting water - others not so great - meaning it's always safe (and ok for brewing or cooking) but not so good for drinking from the tap.

In Scotland (a couple of places I stayed and worked) it's a toss up whether you should drink the tapwater, or go to your local and take another dram from the top row.. those Single Malt Whiskeys made with water from Scotland are amazing... but both are safe in moderation.

In Bangkok, if I don't clean my shower out monthly, it ends up with brown gunge building up, so I certainly don't drink the stuff... and it's hard to know how clean it is (though we're told it's certainly drinkable at source, it has a long way to come to my house - and the pressure of the system is low... another red flag). Visiting tropical islands, you see some resorts are connected via long plastic pipes which are often on the surface (in the sun) and so definitely not the best candidate for anything more than a shower.

In Bangkok too, unless you can test it yourself you shouldn't drink it - but I fail to see why you'd decide to boil dirty water and drink it, seeing as most countries with inadequate tap water have drinking water.

I wouldn't use 'boiled tap water' to make my pasta either.

I have six large bottles which gets topped up each week, to make sure I have plenty of water to cook and drink with... If I didn't, then I'd invest in a good water filtration system.

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.

[–] SomethingClever@lemmy.ml 2 points 2 years ago

Your examples, yes, but I also dont know of any European country where you need to boil the water you drink.

Asian that’s moved to the U.K. here.

Back home, when I grew up I’ve never drank tap water. In my college days I was way too lazy and started just drinking it with a cheap filter. Surprisingly I survived for 5 years despite everyone around me telling me otherwise.

Now in the U.K. I’ve always drank straight from the tap. It’s surprisingly refreshing! And the boiled water taste I can’t really get used to again when I visit home.

The water in Iceland is safe to drink from the tap. Although if I recall correctly it’s pretty sulfuric due to the local hot springs.

I’ve visited a few countries around Europe and have always enjoyed sampling their local tap.

Australian here, never met anyone who boils tap water before drinking it. Some people have filtered water taps installed but our tap water is usually pretty great, I drink probably 2-3 litres of it a day

[–] tmpod@lemmy.pt 2 points 2 years ago

Yes. Here in Portugal, water is drinkable without boiling. Of course, water quality varies from region to region, but as it happens, where I live it's quite good :)

[–] llama@midwest.social 2 points 2 years ago

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!

[–] eggnog@sopuli.xyz 2 points 2 years ago

In the US you can typically drink from the tap but I would advise not, some areas are really bad to drink from the tap, but you should always have a filter at the very least. boiling isn't so necessary.

I once visted Austria (Innsbruck to be precise) and the water there was so incredible straight from the tap. It would be ice cold, so fresh and clean. I think they have the best water in the world there.

[–] boopdepop@lemmy.fmhy.ml 2 points 2 years ago

I visited australia and we had to drink from the tap.

[–] Mishmash2000@lemmy.nz 2 points 2 years ago

New Zealand, Christchurch. We can drink straight out of the tap BUT it was chlorinated while our crappy infrastructure was being upgraded in recent years. Still is in some parts of the city I think? The actual water is from deep aquifers and was pristine and then it went through our dodgy wellheads which have since been upgraded.

[–] degrix@hqueue.dev 2 points 2 years ago

US, Colorado - no need to filter or boil the tap water here. One of the benefits of living at the base of the mountains I suppose
