In India generally people use a water purifier to filter tap water before consumption.

Irish person here. Yes, I drink my tap water without boiling. My water comes from a well as I live in a rural area, but town/city water is drinkable too.

I'm from Italy, here laws for tap water are very restrictive (more than laws for bottle water). Here in Rome tap water is really good.

Here in Armenia all tap water is drinkable as is

Spanish here. I drink tap water, but I have a filter installed in the faucet, otherwise it tastes a bit funny (it is drinkable though).

In USA yes, we drink tap water without boiling as long as we're in an area with safe tap water (most of the population) and not using our own untreated/untested well water. Every once in a while we get alerted to local unsafe tap water. We have a filter on the tap water but haven't always.

US/Canada here as well as someone that has visited most of western Europe (UK, France, Netherlands, Belgium, Luxembourg, Germany, Switzerland) and stayed in hostels - no boiling necessary in any of these places.

There's actually a pervasive myth I've encountered that hot tap water is dangerous and that one should only drink cold water. As far as I'm aware, this myth is due to an old setup for water systems that many western homes had before modern taps. The tap was separated into separate cold/hot faucets. The cold water came safely from the city, but the hot water came from tanks that were stored in people's attics. The water in these tanks sat stagnant and was therefore prone to rats and other creatures dying in it or bacteria building up. This is why still today, most British homes have separate hot/cold taps - to keep the "safe" water separate from the "dangerous" water. I occasionally encountered such taps in the US and I assume that's why my dad raised me to make sure the water was cold before drinking it. My father's understanding of this was clearly outdated though. I learned all of this from a Tom Scott video.

Your examples, yes, but I also dont know of any European country where you need to boil the water you drink.

Asian that’s moved to the U.K. here.

Back home, when I grew up I’ve never drank tap water. In my college days I was way too lazy and started just drinking it with a cheap filter. Surprisingly I survived for 5 years despite everyone around me telling me otherwise.

Now in the U.K. I’ve always drank straight from the tap. It’s surprisingly refreshing! And the boiled water taste I can’t really get used to again when I visit home.

The water in Iceland is safe to drink from the tap. Although if I recall correctly it’s pretty sulfuric due to the local hot springs.

I’ve visited a few countries around Europe and have always enjoyed sampling their local tap.

Here is Jamaica it is safe to drink the tap water without boiling.

Yes. Here in Portugal, water is drinkable without boiling. Of course, water quality varies from region to region, but as it happens, where I live it's quite good :)

Here is Jamaica it is safe to drink the tap water without boiling.

Even better, I do not boil I run though and store in a Brita pitcher that should have had a filter change six months ago!

You'll be fine in Iceland.

I live in Philadelphia and I always boil and filter my tap water. My mother did it when we grew up in New York, then my brother and I continued the practice.

American from Indiana here. Yep, all the time.

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)
