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’ve been to Iceland a few years ago. The tap water often had a strong smell of sulfur, especially in the capital, Reykjavik.

Maybe it’s still safe to drink, but the taste was not great. Even showering was not awesome.

In Germany, Luxembourg and Norway I was drinking it straight from the tap. In Germany specifically, tap water is more regulated than bottled water you buy from the shop, making it safer to drink.

When I was living in Africa (Liberia, Nigeria, Tanzania, Madagascar, Kenya) as well as now in China, tap water is generally considered unsafe for consumption, no matter if you boil it or not, due to the possibilities of heavy metal poisoning. At home I tested my water through a lab (twice with ~24 months in between) and it's free of any dangerous metals or chemicals so I use it for cooking and for my coffee machine, but even though it's supposedly drinkable I wouldn't do so - neither boiled nor fresh.

Same applies for HK by the way, even though you don't have as much heavy industry poisoning the water supplies, the proximity to Shenzhen alone means that there's gotta be a ton of toxic fumes washing down that ends up in your freshwater supply. And while boiling gets rid of bacteria and stuff, many carcinogens are largely unaffected.

Yes I'm drinking untreated tap water in Germany, got a SodaStream to add bubbles sometimes. When we were recently visiting the US (NYC) I drank tap water, too, but my wife didn't like it because of a distinct chlorine smell and taste but I didn't mind

Chinese person in Canada: I just drink cold tap water, but my parents and grandparents drink boiled water. Not really for safety concerns over here, but they, my grandparents especially, subscribe to that traditional Chinese medicine thing of don't put anything cold into your body ever.

[–] dan@upvote.au 9 points 1 year ago

I'm from Melbourne Australia but currently live in the San Francisco Bay Area. Both areas have drinkable tap water without having to boil it.

[–] Flashback956@beehaw.org 9 points 1 year ago (1 children)

Tapwater in Iceland is safe to drink. Went there a couple of years ago and spoke to the locals regarding bottled water. They told me that the bottled water is the 'same' water I get from the tap.

In France I once went to a water museum, yes those exist. They told us that tapwater is safe to drink and that we should stop buying bottled water.

I live in The Netherlands myself and I don't know better then drinken water from the tap. I would go as far as saying that we are among the countries with the best tapwater in the world.

Murican here: I only boil if there's a boil alert, but I always run tap water through a carbon or ceramic filter even though tap water is supposed to be regulated and safe to drink. I think it just tastes better and I am a little mistrustful given disasters like Flint Michigan.

[–] VonVoelksen@discuss.tchncs.de 8 points 1 year ago* (last edited 1 year ago)

Germany here. My family and I drink tap-water all the time. No problems. Sometimes the Water could be contaminated with certain bacteria, but thats rare and the local government will warn you.

[–] jakwithoutac@feddit.uk 8 points 1 year ago

UK checking in here - straight from the tap is perfectly safe. I still put it through a filter though because I like the taste and it makes me feel fancy.

Joining the choir from Italy - we too drink without boiling.

[–] lurkinggizmo@lemmy.ml 8 points 1 year ago

In NL, the public water company pulls their water literally from the exact same springs as the expensive bottled waters (no joke). So our water is exactly the same.

[–] RagingNerdoholic@lemmy.ca 8 points 1 year ago

Canadian here. Municipal water supply is highly filtered and treated. I drink it straight out of the tap.

[–] meteorswarm@beehaw.org 8 points 1 year ago (6 children)

In the US, tap water is regulated to higher standards than bottled! In the rare cases where there is a problem with it, everyone gets notified, for example http://www.msdh.state.ms.us/msdhsite/_static/23,0,148.html.

NYC prides itself on having really good water, both for local food production, and just for taste. NYC did this by buying up land around its reservoirs further inland and building a large aqueduct system. The water isn't even filtered!

That said, some locations have unpalatable water, such as towns near the ocean that get their water from nearby wells.

It's super strange for me to only drink bottled water/filtered abroad.

I've visited Peru and when I said to locals that we drink tap water directly they just didn't believe. It was unthinkable to them. And the bottled water was not cheap there...

I'm Portuguese

Seattle, United States - we drink without boiling although a water district in the area has semi-annual boil water orders for e. Coli and stuff. I've lived in water districts where the tap water tastes funny and lots of people put it through a cheap filter, but I've never minded the flavor.

Basically, the default here is that you don't need to boil or filter your water.... But sometimes contamination happens and then everyone freaks out for a week or so.

I live in the pretty rural u.s. and my water is pumped up from an underground water table, a well that may or may not contain high traces of any number of metals, minerals, or toxic substances, and it's important to have it tested.

I get my drinking water in refillable 5 gal jugs, 2 at a time, from a machine that has pretty intense filters, iirc. So it's pretty much filtered tap water.

A filtration system would be pretty expensive outside of a basic sediment filter, which I have. Showering is fine with my tap water. Drinking it is probably fine too tbh, and I do it once in a while. Though I try to be conscious about my water usage, cause digging a deeper well is out of my power, money wise.

In some cities, there is lead in the water due to infrastructure incompetence, and straight malicious bad actors.

That's not a problem in my home city, and the tap is largely fine to drink.

Eastern US here. Definitely can drink without boiling. I do filter it, though. I'm more concerned about metals and particulates than pathogens.

[–] RandomLemming@lemmy.ml 7 points 1 year ago

I am from Singapore, so I am used to drinking straight from the tap without boiling. In school, we just drink from the taps, or water cooler (which probably have gone through a particulate filter).

When I moved to the UK, I was also drinking from the tap. But I did noticed that there is a lot of scummy residue in the kettle after I boiled water for making tea. That was probably from the hard water in London area. So, if I am making tea, I would use filter water for the kettle. But i won't think twice about drinking straight from the tap still.

[–] CoolBeance@lemmy.world 7 points 1 year ago

Philippines here. You cannot trust the tap water in this country anywhere, even after boiling. You really have to use a good water filter or just buy jugs of purified water from a water station.

[–] Badkid@lemmy.world 7 points 1 year ago

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

[–] anewage0fsewage@sopuli.xyz 7 points 1 year ago

Drank tap water from the faucet for 35 years. Broke down and bought a Breta filter just for the heck of it and never looked back. US citizen btw

[–] milo@lemm.ee 7 points 1 year ago

Dublin, Ireland here. Always drank water straight from the tap. Unless there is some kind of issue with the water system in your area, then a notice will be put out to tell people to boil water before drinking.

[–] TheHerno@sh.itjust.works 7 points 1 year ago (1 children)

Argentinian here, depends on the region of the country, in most places it's safe to drink tap water although it usually has too much chlorine or in small rural cities like mine sometimes there's a bacteria leak on the water so we prefer to buy bottled water

In Lithuania we do not need to boil tap water to drink it and usually it tastes nice unless your plumbing is fucked

[–] supermurs@suppo.fi 7 points 1 year ago

Finland: We drink tap water without boiling.

[–] ARNiM@lemmy.world 7 points 1 year ago (1 children)

In Indonesia, the tap water is not drinkable. Some gets their water from a nation-owned Drinking Water Company (PAM; Perusahaan Air Minum).

The situation is similar, they contain plenty of Chlorine to prevent bacteria from growing. But the distribution system might not be the cleanest. So usually people buy gallons of mineral water and put them into a dispenser.

Some others, takes their tap water from groundwater, pump it into a water tank, and use them. It is not drinkable either.

At home I use Reverse Osmosis dispenser from the groundwater, and it goes through a reminalisation process after the filtration process. I’ve been drinking with this setup for over 15 years now.

Spain here, tap water is safe for drinking everywhere, though you might have some issues in small old towns. But generally you will not contract any illnesses nor have any health issues, 100% guarranteed

I live in America (Minnesota), and tap water has always been safe to drink in my lifetime. There are other places in the US where it’s discovered that the tap water has been unsafe, but that’s generally seen as a huge scandal and a public health emergency, and culprits are tracked down.

It’s my impression that people nowadays drink a lot of filtered water, either through a water tap on their refrigerator that has built-in filtration, or through a pitcher with a built-in filter. I believe people mostly do this for flavor reasons, or out of an abundance of caution rather than any real, concrete concern over the safety of the tap water.

In Minneapolis, every spring there’s typically an algae bloom that makes the tap water taste like vegetation for a few weeks, and that’s gross, but I believe it’s safe. That’s the worst tap water experience I’ve had. When I was a kid, I remember being told that the tap water up at the family cabin was so hard (rich with minerals) that it could make someone constipated, but that sounds like nonsense to me now.

Interestingly, there are places in the US where there’s more lithium in the water than in other places, and studies have been done that show that people in those areas are a little happier (less incidence of self harm, crime, etc.)! So sometimes, the tap water is even beneficial 😜

[–] Fabrik872@apollo.town 7 points 1 year ago

Europe, slovakia tap water is drinkable but the taste differs from city to city i think usualy vilages and tiny towns have better tasting water

[–] colonial@lemmy.world 7 points 1 year ago

Here in the US, tap water is safe to drink, but its "hardness" (that is, mineral content) can vary even between adjacent municipalities. Harder tap might taste "bad" or "off," especially if you're not used to it, but it's actually healthier because of all the magnesium/calcium/whatever.

A lot of people use filtration devices (such as Brita pitchers) to improve the taste, but I don't know anyone who would refuse to drink tap.

[–] smartwater0897@lemmy.ml 7 points 1 year ago (1 children)

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

[–] laxsill@infosec.pub 6 points 1 year ago

Agree. I almost exclusively drink from tap. Bottled water is a waste of money. Boiled water is for tea.

[–] fugepe@lemmy.ml 7 points 1 year ago

Yes. Canada

[–] Anticorp@lemmy.world 7 points 1 year ago (3 children)

Absolutely. We have outstanding tap water here in the PNW. It tastes better than bottled water and is crystal clear.

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.

[–] Hotchillipotato 6 points 1 year ago

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.

[–] Lemminary@lemmy.ml 6 points 1 year ago* (last edited 1 year ago) (1 children)

Hell to do the no. The heavy metals alone would either kill me from anemia or make me go insane. It's bottled water for us in Mexico, unfortunately. :/ Those saying you can safely drink water from the tap in certain countries.. are you sure? Have you measured it yourself? Even some of the bottled water I ran some tests on back in the day were iffy.

[–] average650@lemmy.world 6 points 1 year ago (2 children)

Our water is tested yearly and the reports provided to us with the specific locations reports. There's a handful throughout our town.

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

[–] Wrrzag@lemmy.ml 6 points 1 year ago (6 children)

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

[–] variouslegumes@reddthat.com 6 points 1 year ago* (last edited 1 year ago) (1 children)

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

[–] LimitedBrain@beehaw.org 7 points 1 year ago (1 children)

You'd likely need a really good filter to filter those out, so I hope yours works. And even then, those chemicals are in everyone and everything so they're very hard to avoid.
