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.
Important:
Despite the overall quality of the water in the region, the water pipes can ruin it. If you got lead pipes you should avoid drinking the water or using it for cooking. Boiling won’t change it.
In Germany, landlords are legally required to tell you if there are lead pipes in your house, don’t know about other countries. Typically, the risk of having lead pipes is higher if the house is older.
TL;DR: lead pipes are very bad
I don’t know if it’s actually true, but some have said that the Roman empire collapsed because the lead in waterworks and aquaducts made people lose their sanity slowly.
Likewise, the crime wave of the 70s in the US has been directly linked to leaded gasoline putting lead in the air, and leaded paint. You can map the crime wave literally block-by-block to correspond with areas that have not done lead mitigation efforts or those that have.
Also makes you think about the pathologically evil governmental policies the older generation have enacted, and how those people have also been influenced by lead in the air.
I’m of the understanding that lead poisoning effects the ability to engage in theory of mind (thinking about what someone else is thinking— also, empathy) and future planning, consideration of consequences, first before influencing other mental faculties. Which is why it can be linked to crime so easily.
Is it legal to rent out an apartment without drinking water in Germany?
Also, just because it’s lead pipes, it doesn’t mean that it leeches into your water, usually there’s a thick coating on the pipes from the inside. You can always test your water for lead.
