Ah, yes, the IQ benefits of letting machines think for you and blindly trusting what they spit out, while you atrophy your own critical thinking skills and lose the ability to have independent critical thought or produce any kind of useful analysis without said machines, so you develop a need to consume gallons of water and burn square acres of forest every time you need to do any kind of analysis or write anything of substance… yeah, those IQ benefits. Sure.
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)
Why not a fifth or even just an tenth as popular as reddit? I get wanting it to be more active, especially for the niche communities to feel more active, but the last thing I want is to go to the “All” tab here and see anything remotely like /r/all on Reddit.
