There is distilled water, deionized water, and the purist
distilled-deionized water. Ask a chemist who measures trace elements in
parts per billion (ppb) or parts per trillion (ppt).
This is correct, finally. It was very annoying to listen to all the
other 'correct' opinions for so long.
It doesn't address the corrosive aspects, however. I had a very
interesting conversation with an elderly gentleman at the model railway
about that, but I am not enough up to speed on it to teach it.
I did spend a couple years in a thermal generation facility however, and
all their feedwater was deionized to the eyeballs, as I recall, except
in the lab where it was double deionized - we were instructed not to
drink it. It didn't seem that large parts were rusting off - quite the
reverse. I admit to not knowing much about the topic. I used to stop
and gaze at the attractive red and blue balls.
