Much thanks. I have a decent collection on construction, gardening, livestock, and practical trades, but lean on surveying and ground water. Also have the Foxfire series which is great.
'Living on 5 acres' is good, too, but leaves out important details.

You don't want to know the details of what kind of water I cooked with in Alaska, while with the military. It was good and safe, when we finished, but I tried not to think of where it came from.
Boiling surface or sub-surface water is always an option, if you can't drill 160-400 ft and run a well.
Always pour boiled drinking water between two containers for a few minutes to re-oxygenate it and make it more palatable.
