Fantastic link. We had the maintenance guy at work telling a few others huddled in the lunch room that our USP grade water was toxic to drink. He had heard this from the Tech Ops head (head of all chemistry). I laughed. I told the guy, "Water is water". He said, "No it will suck the minerals out of you." LOL. As I proceded to explain how and why this was not possible, he said, "So you know more than a doctor now?" I said, "This is basic biology and chemistry". I brought it up to the other members of my team (all chemists) and they laughed. We all agreed DI and RO water isn't necessarily the best water to use as your staple but it ain't gonna kill you to drink.
Just an added bit of info: if your TDS is inline, throw a pinch of aquarium salt into your reservoir to "re-ionize" the water. This slows it from sucking goodies out of the air and container.
Bleeding stomach ... :laughroll
