Underground well water. Doesn't go back to the city either, but a sewage pond.
No fluoride
It's almost always chlorinated before run onto tap. Though, have to be careful of runoff's coccidia and giardia.
I drink it sometimes or at least make drinks with it. Good source to stock up from.

Has anyone thought of a solar still water collector, I bought one at a bushcraft exhibition. It was made by an ex SAS soldier.
And here is the website; www.kaktush2o.co.uk...
It's cheap, lightweight and it's good for a bugout bag. Haven't tried it yet but I plan to this summer.
Just a thought.
I also heard today that activated charcoal is suppose to filter radiation from water, do you think that is true?
