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 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 😜
