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.

Poland: I drink tap water everyday, it's safe to drink, it's tasty and it's cheap :)

[–] [email protected] 10 points 2 years ago

Correct me if I'm wrong, but I think the EU has regulations that say tap water should be drinkable as-is.

That said, in some places it may taste a bit weird - and by place I mean even in the same city. I live in a city in Hungary, lived in four different buildings on different parts of the city. 3/4 the water was fine 99% of the time, though the fourth one was absolutely nasty. Didn't live there long luckily.

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.

Hong Kong: safe to drink from the tap. I filter it for taste and do not boil it.

Here is a recent government test, which I think is a good complement to asking what people do or do not do.

I believe in Canada we have high standards for our potable water, unlike the UK for example our water heaters need to be up to par (UK typically has seperate taps AFAIK).

So no need to boil, also if you're trying to get rid of chlorine you can just use Brita filters, carbon filters that restaurants use do the same AFAIK. Also even cities like mine which (at least at some point before now) had way more houses than apartments still chlorinated the entire city's supply.

Filters are insanely good these days. I was thinking about getting a life straw, but there's a slightly more expensive alternative that can do like 500x more filtering before it needs to be replaced, and comes with a pouch you can fill and then pour into a regular water bottle. Life straws are meant to be drank from directly, and the alternatives that company offers are just water bottles with life straws built in - so you put unfiltered water in the bottle itself... Probably gets gross or requires constant cleaning

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

[–] RagingNerdoholic 9 points 2 years ago

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

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.

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.

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

[–] [email protected] 9 points 2 years ago

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.

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.

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.

Portugal πŸ‡΅πŸ‡Ή, we drink tap water here it should be fine unless you're in an old building and the pipes haven't had any maintenance. Been in old buildings in Lisbon that had brownish/tan water and I had to let it run for a good 30secs until it came out clean.

Never drank water from there unless I was desperate, always used bottled water. However, where I was raised the tap water there is sooooo good.

Also I'm absolutely biased and conditioned by living here my whole life, but I've visited a lot of countries. And no tap water is even close to Portuguese tap water.

P.S. Been to HK just about a month and I really found it charming. The way "western" culture is applied there. Mostly on buildings and lamps etc. While on the other side you have traditional temples. Very cool

Shame for the past couple of events there (cough CCP cough)

Finland: We drink tap water without boiling.

[–] [email protected] 8 points 2 years 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.

[–] [email protected] 8 points 2 years ago

In the United States, it is a little bit different.

There are "standards" that water quality has to live up to. Do these standards actually meet the criteria for safe drinkable tap water? Not always. This is evident in places like Flint, Michigan and other poorer urban areas.

Some of the tap water can be so bad that people wouldn't dare to drink it even after boiling.

In some areas, the tap water quality is wonderful.

Here is a relatively decent source about the topic as it pertains to the USA. https://wisevoter.com/state-rankings/best-tap-water-in-the-us/#:~:text=The%20ten%20states%20with%20the,%2C%20South%20Dakota%2C%20and%20Nevada.

The long story short here, is certain places like Hawaii have extremely clean tap. Other places, like Texas, are notorious for having numerous water quality violations.

It falls down to each individual State and City for maintaining the standards that were set. In my opinion, it it just an easy way for them to waive liability at the end of the day.

Canada here - I drink water straight from the tap.

Although Canadian tap water is some of the highest quality tap water in the world.

I live in a major Italian city, I'm well over fifty, and I've always drunk unfiltered water straight from the tap without boiling. Some Italians apparently don't like the taste of tap water but it's still safe to drink it unfiltered and unboiled in nearly all the country.

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

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.

[–] [email protected] 7 points 2 years ago

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

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

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

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.

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

[–] [email protected] 7 points 2 years 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.

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.

[–] [email protected] 7 points 2 years ago (3 children)

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

Here in Austria we drink our tap water as it is. It comes basically straight from the mountains, you can't get any better.

In our biggest city, Vienna we even have the best water in the country (in my opinion) if you live on the West side of the Danube river. I miss the Viennese water, no joke!

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 😜

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 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.

[–] [email protected] 7 points 2 years 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.

[–] [email protected] 7 points 2 years 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

[–] [email protected] 6 points 2 years ago* (last edited 2 years ago)

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
