Chlorine in tap water will kill your gut microflora with long term use. Some more sensitive bacteria (reuteri) are most important for immune system! At least leave tap water stand still for couple of hours, so the chlorine gets out!

That doesn't appear to be the case[0], but I'm no expert on these things.

What I do know is that water chlorination can provide safe drinking water for millions who don't (or didn't, until their water was chlorinated) have safe drinking water.

That was my first thought and it's a good one, if such things concern you.

For leaving water out to sit, I've heard from fish owners that you have to be careful that it is a chlorine system and not chloramine which doesn't so simply evaporate out:

I grew up basically expecting clean drinkable water every single time I turned the tap.

It's pretty sad to see that isn't the case anymore, assuming it ever was in the first place. Nobody in a nation with as much wealth as we have in the US should have to plan a glass of water hours in advance to make sure they aren't being harmed or have to buy and maintain expensive filters for their home.

We really need to start demanding better.
