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.

In Sweden, yes tap water is safe without boiling. Might want to filter for taste reasons.

I would drink the water in Iceland without boiling it, probably without a second thought. In fact, I wouldnโ€™t be surprised if it tastes amazing.

We filter our tap water here in Korea. Most people do, but as I understand, it's safe to drink it just straight from the tap. It's just better through a machine that gets rid of any lingering chlorine and heats it or chills it for you.

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.

Croatia here,

tap water is completely drinkable and safe without any boiling. Exception are some more remote islands, so if you are going on some island, chekc if the tap water is drinkable.

Fun fact: Croatia actually uses drinkable water for toilets as well, altough i would not drink from a toilet :)

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.

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

[โ€“] [email protected] 3 points 1 year ago

One thing to consider: While tab water in most of the developed world is potable,any water safety guarantees usually end where the house water pipes begin. Depending on the state of the piping, tap water might not be safe, even if the water supplyer says it's safe.

You can get a water test (especially bacteria is important) for relatively cheap. Last time I did such a test it was ~โ‚ฌ60. It's not wrong to do one.

Also, the definition of potable water is that the water is potable after the tap has been running for 10(!) minutes.

Bacteria contaminated pipes are pretty common and if the water has been sitting in these biofilm-covered pipes over night or even longer, the water can become pretty harmful. Especially after you get home from a vacation, letting the water run for a decent amount of time might be a good thing.

Also: the worst thing that can happen to your water pipe system are blind pipes, so pipes that are connected only on one end. That could be e.g. left-over plumbing after remodeling or pipes that lead to unused taps. If at all possible, these ahould be removed or flushed at best daily.

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.

German Here, we have really good Tapwater here.

[โ€“] [email protected] 3 points 1 year ago (1 children)

The US varies widely. Some Americans in this thread tell you their tap water is squeaky clean. Meanwhile, there are places like Flint where the tap water not only is deadly but remains deadly even if you do boil it.

Depends on how acclimated your stomach is. Locals may be able to drink without problem but foreigners may have stomach problems.

Luxembourg here, i'll drink straight from the tap.

[โ€“] [email protected] 3 points 1 year 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.

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.

[โ€“] [email protected] 3 points 1 year ago

Just ask someone from there on day one. They can obviously tell and i think this is the best strategy. I bet it's safe like in most parts of middle and northern europe.

[โ€“] [email protected] 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.

From Singapore. Tap water here is potable but we boil it first out of habit. (But I use tap water for drinking when boiled water has run out).

[โ€“] [email protected] 3 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.

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

I'm from Denmark, and water is safe to drink straight from the tap here.

[โ€“] [email protected] 3 points 1 year ago (1 children)

I am in Japan and have no issues with tap water here, used to drink it regularly.

I live closer to Mt. Fuji now and go get spring water from the mountain weekly instead. There's a basin at a shrine nearby that collects it and is free for people to take. No issues with the tap water, but this water tastes a lot better.

Poland here, tap water is pretty drinkable in cities, not sure about rural areas though, also I personally use Brita filter just to be sure

[โ€“] [email protected] 3 points 1 year 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.

[โ€“] [email protected] 3 points 1 year 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!

[โ€“] [email protected] 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!

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