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.

Finnish here and the tap water here is one of the cleanest in the world, so yeah, I drink straight from the tap.

Switzerland here,

Yes we absolutely drink tap water here, not only it is well regulated but it may also beat many bottled water in terms of taste..

[–] [email protected] 5 points 2 years ago

Canada here - tap water is just fine, I filter it at home since I prefer the taste but I've never been adverse to drinking it straight

Australia here, yes most people drink it without boiling but it depends a little what region you’re in. Some bits of the fat north or some island towns, you may be better off boiling it. Lots of people in the city use built in filter taps but I kind of write that off as con job.

Bermuda here, straight from the tap!

It actually gets collected from rain water on each individual home's roof. The roofs are lime-washed to kill the really nasty stuff as it runs down in to a holding tank under the house. Some times you get dead critters in there, but nothing larger than a small lizard or bug. They tend to sink to the bottom of the tank, below the outlets.

Most Bermudians swear by a "cup of bleach" thrown down there every couple of years. It's in to a tank that's 10,000gal+ at a minimum (mine's over 40,000), so it's basically homeopathy at that point - but the lime-wash works!

The only place you'll want to avoid it in Bermuda is in the City of Hamilton (mains, not great quality), a house with a dirty roof, or in one near the sole power station on the island. This is an on-going fight to get them to adhere to the emissions safety standards they claim to.

White roofs and smoke stack in the picture!

I live in central Canada. I've always been able to drink from the tap here. (Unless there has been a rare case of a pipe burst or other reasons when notified to boil the water first.)

We've also fluoride to our water since 1956 as a public health measure to prevent tooth decay and promote dental health. The dose is 0.7 mg/L according to my city's website.

[–] [email protected] 5 points 2 years ago

northern USA and we have some of the cleanest tap water in the country. Drink it all day from the tap you will never get sick from it, just tastes like nice water.

[–] [email protected] 4 points 2 years ago

In Finland I drink straight out the shower head, it's fun and wonderfully safe.

I lived in Taiwan and was taught to boil. I'm starting to think you probably don't need to but we just grew up not knowing any better. In Australia you don't. I drink out of any tap that's not a rain water tap. Lots of Asians here still buy bottled water or boil water out regardless. So it seems to be out of uninformed fear or habit.

My belief is unless a local government/health authority tells you you can't drink straight from the tap. I'm inclined to believe it's safe.

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.

[–] [email protected] 4 points 2 years ago

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

[–] [email protected] 4 points 2 years ago

Not at all...where I live tap water isn't clean at all. It comes in a white colour with pression. And mining industry contaminated a lot

[–] [email protected] 4 points 2 years ago (3 children)

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.

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

I do. When I was a child, I was even confused about why people don't drink tap water but buy them instead from shops or why they boil or someway disinfect them.

In switzerland, we can drink the tap water without boiling it first.

[–] [email protected] 4 points 2 years ago

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.

[–] [email protected] 4 points 2 years ago

In England we drink straight from the tap. I live in London which has incredibly hard water so it's not the nicest tasting and it will leave white residue on the glass but it's not bad for you.

[–] [email protected] 4 points 2 years ago

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

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.

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.

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.

[–] [email protected] 4 points 2 years ago

In Canada I don't boil it.

In Vietnam, I do. Although more because I'm always making tea than anything else. Unless it's well water, in which case that's only for doing dishes, I won't drink that.

I did nearly die from cholera some years back, but it was probably not from the tap water specifically. Sanitation and food safety has really improved here in the last decade, I'm happy to say.

[–] [email protected] 4 points 2 years ago

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 wouldn’t be surprised if it tastes amazing.

[–] [email protected] 4 points 2 years ago* (last edited 2 years ago)

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.

[–] [email protected] 4 points 2 years ago* (last edited 2 years ago) (1 children)

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.

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

One thing about tap water in the USA is that, while you can drink it, water taste varies a lot.

For instance, in the Southwest USA, it is very common for bottled water to be sold in gallons. There are even small stores whose main purpose is to filter tap water to remove minerals.

You also have the use of non-potable "grey" water that is treated sewage water that gets used for irrigation. You'll usually see signs to not drink that water.

[–] [email protected] 4 points 2 years ago

nyc us here, only boil water if there is a warning due to a pipe break or something.

[–] [email protected] 4 points 2 years ago

In the Philippines, we don't drink from the tap. At all. It's quite dangerous and there have been a number of internet personalities that got stomach aches from drinking tap water ^cough^ ^haachama^ ^cough^

Instead, there are a lot of establishments here that sell drinkable water at a fraction of a dollar per 5 gallons.
