Just takes one round with the beaver fever to get a guy filtering...(grin)
This^^^^^
As a professional hydrologist, I never drink raw unfiltered/untreated water. I've tested alot of pristine water and it all has varying amounts of bacteria, mostly coliform bacteria of some sort and concentration. Had a dose of Giardia a few years back. I never drank any raw water but did gut an elk on that trip. One round of Giardia is usually enough to 'encourage' filtering.
