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.
Editted: 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.
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.
