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.

Here in Armenia all tap water is drinkable as is

[–] JASN_DE@feddit.de 2 points 1 year ago

German here. Yes, constantly. The only reason to not do it would be taste (personal preference) or sometimes due to pollutants entering the system, which is explicitly communicated by the city.

Hello Mr Hong Kongnese. I'm a Brit. We don't boil water here and I've visisted Iceland - they don't boil it either.

Diu gau lan tsat hai - Merry Christmas. Enjoy your holiday.

Where I live in the US, I don't have a need to boil water unless I'm cooking or making tea, and am safe drinking the tap water. I consider myself lucky.

[–] PetrusHyde@lemmy.ml 2 points 1 year ago (1 children)

Spanish here. I drink tap water, but I have a filter installed in the faucet, otherwise it tastes a bit funny (it is drinkable though).

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

[–] ikidd@lemmy.world 2 points 1 year ago* (last edited 1 year ago)

Modern treatment plants don't use chlorine anymore, they use cloramines that have little scent or taste. This is most likely the case in HK as well.

Boiling water that doesn't need to be boiled is a waste of energy and GHG.

[–] JaneDoe@lemmy.ml 2 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.

[–] nick@campfyre.nickwebster.dev 2 points 1 year ago (1 children)

New Zealand and yes it's safe to drink without boiling here. I do run the tap for a few seconds to clear out any standing water before drinking anything though.

[–] Aaron@lemmy.nz 2 points 1 year ago (1 children)

Also NZ, South island, only time I boil water to drink is for tea β˜•

Tastes great right from the tap.

[–] nick@campfyre.nickwebster.dev 2 points 1 year ago (1 children)

Haha true, although I'm more of a coffee person myself.

I didn't know there was a NZ lemmy instance, I've got some new communities to subscribe to.

[–] wildeaboutoskar@beehaw.org 2 points 1 year ago (2 children)

UK- we don't boil water here unless there's an issue with the pipes. I got told not to drink the water in places like Spain and Italy as it could make me unwell, but not sure if that's as big a deal now.

I live in Vietnam and tap water is always boiled before drinking. Our tap water sucks.

[–] thelittlea@lemmy.ml 2 points 1 year ago

US here. Although we have a water municipality, I still drink bottled water or water through a filter. I had my water tested by third party lab and found out they over chlorinate which leaves a lot of disinfectant byproducts in the water. I’m looking to get a whole home water filter installed to remedy that.

[–] jg1i@lemmy.world 2 points 1 year ago (1 children)

I'm in the US. I don't know too many people that drink directly from the tap. Almost everyone I know passes the water through a filter first.

Although, technically, I think the water is safe to drink. My city sends little informational cards saying how they've tested the water and it should be good to drink straight from the tap.

I think we in the US scare easy, so I'm guessing Big Water Bottle and Big Filter have brainwashed us into being scared to drink straight from the tap.

[–] imPastaSyndrome@lemm.ee 2 points 1 year ago (2 children)

Ehhhh I've been on one well or another for most of my life and the times in between when I was on city water it was not good, My parents ran the water association for the neighborhood that we were in and I know how much work they had to put into to make it viable and tested well... And not taste like bleach. Yuck

In India generally people use a water purifier to filter tap water before consumption.

[–] zakiuem@lemmy.ml 2 points 1 year ago

When I was in Cainta, Rizal, Philippines, my uncle always boils tap water before drinking. This is indeed a safety measure. He doesn't buy gallon bottles of drinking water.

[–] TONKAHANAH@lemmy.world 2 points 1 year ago

no and no. The tap where I live taste nasy, i think its safe to drink but its not very good so I dont use it.

[–] flexcyness@lemmy.ml 2 points 1 year ago

I am from the Philippines, and in my city, there are districts that have unpotable water and they resort in using purified water for drinking and cooking. In my district though, water is very potable and we drank it until switching to purified water last year because our water provider got their system contaminated.

US/Canada here as well as someone that has visited most of western Europe (UK, France, Netherlands, Belgium, Luxembourg, Germany, Switzerland) and stayed in hostels - no boiling necessary in any of these places.

There's actually a pervasive myth I've encountered that hot tap water is dangerous and that one should only drink cold water. As far as I'm aware, this myth is due to an old setup for water systems that many western homes had before modern taps. The tap was separated into separate cold/hot faucets. The cold water came safely from the city, but the hot water came from tanks that were stored in people's attics. The water in these tanks sat stagnant and was therefore prone to rats and other creatures dying in it or bacteria building up. This is why still today, most British homes have separate hot/cold taps - to keep the "safe" water separate from the "dangerous" water. I occasionally encountered such taps in the US and I assume that's why my dad raised me to make sure the water was cold before drinking it. My father's understanding of this was clearly outdated though. I learned all of this from a Tom Scott video.

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.

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.

[–] SomethingClever@lemmy.ml 2 points 1 year ago

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

[–] sajran@lemmy.ml 2 points 1 year ago

You can safely drink unboiled tapwater in most places in Poland.

[–] Schooner@lemmy.ml 2 points 1 year ago

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.

[–] degrix@hqueue.dev 2 points 1 year 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

[–] computerfan0@beehaw.org 2 points 1 year 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.
