The point he is making is not reduced to that, it is that you should judge things with the same metrics. I.e. how much water is used for bottled water? For running water? How much harmful chemicals can you find in soft drink, bottled water, tap water? (because running water may be very cost-efficient, but it comes with a price, the dizzying quantity of chlorine you can find inside being one).

Just giving one number out of your hat is a dishonest persuasive move (unless everybody already knows the numbers for all the previous questions), precisely because the author knows very well that most people cannot put that number into perspective. This is not a very scientific attitude for something published in a 'scientific' journal.

Despite what you might think water is not a particularly limited resource.

At the municipal level 1 cent ~= 1,000+ gallons of water but this can vary greatly by location. As a customer in many ways you are paying for pipes not water.

PS: California farmers often pay ~70$ on average per acre foot or 325,851 gallons. But, they also get a lot of water for far less than that it's the rare edge cases that are really expensive. http://westernfarmpress.com/water-70-24-million-acre-foot

I agree with you. But what if you want to drink pure/purified water? You can do for little to no cost in certain conditions, but for city people there are either bottled water or some purifying systems that can be costly and of various levels of efficiency. Then, how much water does one liter of water costs?

But then you could argue that people don't need to drink purified water, tap water is good enough, lead levels, chlorine levels (etc) are low enough. But this is another question from the previous one, that should also be discussed taking the whole picture into account.

Distilled water will also osmotically drain you, although not at any level you should be worried about. But it's not at all clear that it's "better for you" than water with stuff in it.
