You misread what I wrote. Water is the same solvent as both regular water and ultrapure, I was replying to the ultrapure part.
Also: I appreciate you found a source, unfortunately it's not true what they said. It's not possible to "leech nutrients through the hair to the scalp", the wrench story is not true either - there is zero chance a lab with the standards they have would just leave a wrench at the bottom of the pool - it would contaminate the water. Not to mention the bottom is filled with more of those light tubes, so there is no place for a wrench to sit. (And if someone dropped one it would break a tube.)
I don't know why someone would tell businessinsider such stories, but they are not true.
It's hard when a supposedly reliable news place writes things that are not true, but that's the world we live in. I guess technically they are just quoting stories they were told.
(My personal pet peeve is a news source that made everyone think you can't leave eggs outside the fridge if they were washed, (as they are in the US). This is not true, but "there's a news source".)
I think people might be confusing ultra-pure water with "DI water" (deionized water).
DI water is AN AMAZING SOLVENT. Waaay more powerful at dissolving low-solubility solids than tap water, or even distilled water. It's stunning IRL to see how much better it cleans optical surfaces, where single-molecule layers can visibly change the appearance.
But if left open to the atmosphere, as in these pools, it would soon be just plain old (pure) water. Ultra-clean, but not an ultra-solvent.
