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.

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

Here in El Salvador, you can drink tap water safely depending the region you are.

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.

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.

I live in the Netherlands and we drink tap water without boiling.

Australia here - we drink water straight from the tap, but I picked up the habit of drinking boiled water from my frequent trips to Shanghai.

Argentina, drinking filtered tap water rn (not boiled). It's said to be safe but quality may vary throughout the country. Although it's not recommend for small childrens

[–] GNUgit@lemmy.perthchat.org 4 points 1 year ago

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.

Lemmy isn't blocked in Hong Kong? Oh I guess its much more difficult since they'll have to block all lemmy instances.

Anyways, here in the United States of America, tap water is safe to drink, except in certain places like Flint, Michigan, but thats more of a lead pipe issue than a germ issue. I regularly drink water directly out of the tap, I don't have any health issues that result from drinking water.

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.

Straight and fresh from the pipes! Writing from Transilvania, Romania.

Here in the UK we just drink straight from the (cold water only by law due to differring regulations) tap without boiling and that's been the case for decades at the least across the entire nation. There's just no need to boil the water here unless you are cooking.

It's also safe in Iceland, I went there and their water is crystal clear and pure since it's sraight from the glaciers. You could drink out of a random stream there.

Philadelphia, PA, USA. We don't boil it, but I have a filter on the tap. The drinking water here is safe, but it smells funny, and my family filtered the water even back when we lived somewhere with better tasting water.

I live in Sweden. Yeah, the tap water is clean and can be drank straight from the tap without boiling, filtering, or treatment in the whole country.

Scotland here. We don't boil water before use.

I have family down in North West England that do have to do this, though. They live in an area where there is a thin layer of soil and a lot of clay. The water isn't particularly hard but it also doesn't taste very nice if you don't boil it first.

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 grew up on well water and was used to drinking from the garden hose when working out in the yard; but thats southern US for ya.

Now days, jus fill a bottle from the tap and don't really put much thought to it.

[–] plum@lemmy.ca 4 points 1 year ago

Canadian in a major city - yes, safe to drink right from the tap.

However, many remote communities here do not have access to safe drinking water.

[–] valdisnei@lemmy.ca 3 points 1 year ago

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

[–] Solemn@lemmy.dbzer0.com 3 points 1 year ago (1 children)

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.

[–] nigelinux@lemmy.ml 3 points 1 year ago

Yea, now I'm looking forward to Iceland's tap water!

[–] kairo79@lemmy.ml 3 points 1 year ago

German Here, we have really good Tapwater here.

[–] trachemys@iusearchlinux.fyi 3 points 1 year ago (12 children)

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

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.

[–] exohuman@lemmy.dbzer0.com 3 points 1 year ago

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.

[–] whatsinaname@lemmy.world 3 points 1 year ago* (last edited 1 year ago)

I have been to Iceland recently and tap water is absolutely fine to drink directly and preferred. No one there buys water. Just make sure you drink the cold water and not the hot one as the hot is from natural thermal springs so may contain some minerals I belive. Just carry your own bottles and you can fill up the cold water from anywhere, even restaurants will refill free.

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

[–] dandroid@dandroid.app 3 points 1 year ago

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!

I live in the great lakes region of Canada and our tap water is totally safe
