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.
US here. Yes, can confirm I can, and do drink water from the tap without boiling. The city provides, maintains, and regularly checks the safety of the water. Notices are put out if something damages the pipes and a “water boiling” policy is put out promptly over local radio and/or newspaper.
It depends on where you live in the US for sure. Not everywhere has drinkable water. And even more places have poor-tasting or very hard tap water.
One thing to consider: While tab water in most of the developed world is potable,any water safety guarantees usually end where the house water pipes begin. Depending on the state of the piping, tap water might not be safe, even if the water supplyer says it’s safe.
You can get a water test (especially bacteria is important) for relatively cheap. Last time I did such a test it was ~€60. It’s not wrong to do one.
Also, the definition of potable water is that the water is potable after the tap has been running for 10(!) minutes.
Bacteria contaminated pipes are pretty common and if the water has been sitting in these biofilm-covered pipes over night or even longer, the water can become pretty harmful. Especially after you get home from a vacation, letting the water run for a decent amount of time might be a good thing.
Also: the worst thing that can happen to your water pipe system are blind pipes, so pipes that are connected only on one end. That could be e.g. left-over plumbing after remodeling or pipes that lead to unused taps. If at all possible, these ahould be removed or flushed at best daily.
In this US, yes, we generally trust our tap water (although there have been notable incidents of water infrastructure failures, such as major lead contamination in Flint, MI), to the extent that if you get a drink in a restaurant here, 99% of the time it’s going to be mixed or made using tap water, with ice made from tap water.
Some folks will use a filter (Brita brand filter pitchers used to be popular at one time, with TV ads and everything) but that’s more for filtering out chemicals/toxins/minerals than anything else.
In rural places, every now and then the local government or water company (yes, a lot of places here have privatized water infrastructure which is not super great) will put out a ‘Boil Water Notice’ but this is generally considered outside of the norm, and you usually expect to see that kind of stuff resolve within a couple of days unless it’s a result of a major disaster (we were under a Boil Water notice for 2 weeks after hurricane Katrina in my area, the longest stretch I ever remember). Boil Water notices are usually a result of either a breach of the infrascture (a pipe collapsing and the water supply getting dirty), or a water supply failing its regular quality/safety tests. Our water (can’t speak for everywhere in the US, and don’t really know the specifics of how they do it) is chemically treated and filtered before it goes into the tap, and the supply mechanisms are usually regularly tested to make sure they’re within safe standards.
All of that being said, I know people who refuse to drink tap water, mostly because it tends to have a distinct taste from treatment and from having minerals in it, but also because they’ve heard horror stories like in Flint. Two things: those folks normally drink bottled water, which is usually just bottled-up tap water from some other place; and I usually see those folks gladly drinking fountain drinks/tea/etc at a restaurant, which is made with un-boiled tap water and served on tap-ice.
TL;DR - the tap water in the US is generally considered safe to drink, in most places, with notable exceptions, and for now (our mostly-privatized infrastructure is getting worse and worse, and very public failures have started to appear in not only water infrastructure, but everywhere)
Lol, I was you 10 years ago. For context I’m Malaysian and we only drink water that is first filtered and then boiled. When eating outside we generally avoid iced drinks unless it’s a reputable shop.
Then I moved to Australia and reacted with utter horror to see my then-bf drink straight from the tap. I was like wtf you’re going to get parasites! Spit it out!
Now I drink water like Aussies and my kid refills her bottle from the tap too. My parents, when they visit, still boil water to drink but they’ve at least stopped thinking we’re trying to murder their grandchild.
Tap water in Brazil is supposed to be drinkable, but I use a filter anyways because I don’t trust the companies.
México. NO. Do not drink the tap water. Boiling does not help. It has a bunch of heavy metals and other contaminants in it. It sucks because mechanical filtering is incapable of removing them effectively. Reverse osmosis does but it is a challenging and expensive process to properly keep in your house. We always buy bottled water. Trucks deliver twice a week.
yep, i’ll drink straight from the tap. i live in california, united states. it is even common to have drinking fountains in public spaces: special button activated taps that spurt cool tap water into the air for you to drink from.
I live in Melbourne Australia and we drink water straight out of the tap. Even restaurants give you tap water
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?
Yes. It’s a bit of a scandal when that’s not true. (Canada here)
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.
Boiling it has to be “force of habit”, then. I wonder how long it’s been potable. I’m guessing mainland China is mostly boil-first.
At home I exclusively drink tap water. I only boil it for tea sometimes :) I‘m from Germany.
In Germany tap water is considered “one of the most strictly controlled food products”
good quality water is an underappreciated factor in quality cuisine.
Yes. And i’m always stunned by how many people buy loads of bottled water at the Getränkemarkt. Just drink it from the tap or get one of those machines that make sparkling water if you like that?! There is no chlorine in ordinary german water and it tastes just fine.
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.
Australia here, yes most people drink it without boiling but it depends a little what region you’re in. Some bits of the fat north or some island towns, you may be better off boiling it. Lots of people in the city use built in filter taps but I kind of write that off as con job.
