My wife has a love of bottled water.
She will use ice from the ice maker in the freezer, but the water that makes it isn't fit to drink.
I will drink bottled water, but that is a last resort. I have drank from puddles, and a dirty river that I grew up near. Fishing gear was far more important to lug than water, plus the river had plenty of water to drink. I don't know how I never got sick from it, must have been cleaner than people thought!
