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 never drink water out of the tap because I prefer to filter it first. It’s safe to drink but I want it clean and much colder so into a filter pitcher and put that in the fridge
I remember reading once (perhaps from UFC Que Choisir, a French consumer association), that filtering decreased the quality of water (in France), because the tap water quality was very good and controlled, your filter not so much, and it may develop bacteria.
To answer the original question, I always drink tap water in France, and have never once boiled it. I know people who filter it. I sometimes put it in the fridge if I want it colder. I’ve also drank tap water directly in the UK and in Germany. I would in any European country.
