> Wrong [...] 45 million [...] 28% of the U.S. population

I don't think it's fair to call the comment "Wrong". If anything, this supposed refutation is saying "Right".

I might be taking words out of context, but 45 million is nowhere near 28% of the US population; this is a little under 15%. I am not arguing for or against the problem of water pollution, but this is just seriously suspect math.

You've essentially proven their point. Outside a few problem areas, water in the US is remarkably safe and clean. The US population minus "nine to 45 million" definitely qualifies as "most places" in America. And that's not even close to 28%, by the way.

Most people in the world have it far worse off than the US. We tend to easily fly into a panic and start drinking bottled water instead, which only pumps ever more plastic and carbon into the biosphere. That exact phenomenon happened in Austin recently. People went into a prepper panic and raided the grocery stores anyway, completely cleaning out all the bottled water in the city. Again. The water was perfectly fine, it turns out.

My travels through the third world have made me more aware of how much we take our highly reliable infrastructure for granted. Of course we still have some problems to work out, but acting like most tap water is unsafe is hyperbolic and just not helpful.
