That's more of an indictment against bottled water than it is an endorsement for tap water. Both bottled and tap water are too often full of stuff you don't want to be drinking.

A drip (aka wick) filter is a cheap enough way to remove a lot that.

I guess that depends on where you are.

Yes, of course. That was my point. That the heuristic of "developed country" is not effective just because it's sometimes right.

Also take a look at the number of contaminants in the water for each those cities in your source. It's not zero for any of them.
