My little boy drinks bottled water. First of all, at least where I live, tap water has chlorine. Which seems to carry some risks (see, e.g. https://pubmed.ncbi.nlm.nih.gov/12594192/ https://pubmed.ncbi.nlm.nih.gov/12594192/). Secondly, my building has copper and PVC pipes, which are also suspected of having some adverse health effects. Thirdly, where I live, sometimes (about once per month) tap water comes out brown. Authorities typically say that it's fine to drink, and I suppose they analyze it and it conforms to some official standard, but I'm not going to drink or give anyone brown water. And that also makes me think that maybe the days it doesn't look brown to me, it might be also somewhat brown, just maybe not brown enough for me to notice. Maybe I'm wrong and plastic from bottles is much worse than these things, but I don't think you should be so amazed that people can prefer bottled water. At the end of the day, it's a matter of picking your poison... with incomplete information.
