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.
In Germany, Luxembourg and Norway I was drinking it straight from the tap. In Germany specifically, tap water is more regulated than bottled water you buy from the shop, making it safer to drink.
When I was living in Africa (Liberia, Nigeria, Tanzania, Madagascar, Kenya) as well as now in China, tap water is generally considered unsafe for consumption, no matter if you boil it or not, due to the possibilities of heavy metal poisoning. At home I tested my water through a lab (twice with ~24 months in between) and it’s free of any dangerous metals or chemicals so I use it for cooking and for my coffee machine, but even though it’s supposedly drinkable I wouldn’t do so - neither boiled nor fresh.
Same applies for HK by the way, even though you don’t have as much heavy industry poisoning the water supplies, the proximity to Shenzhen alone means that there’s gotta be a ton of toxic fumes washing down that ends up in your freshwater supply. And while boiling gets rid of bacteria and stuff, many carcinogens are largely unaffected.
