The treatment and filtering of water is usually just precautionary. Nobody is going to start slurping cow piss out of a muddy hole if there is a better alternative around. You might not know if a bear crapped in the creek or if some dead animal is a few yards away in the lake.i have a creek a few hundred yards from me .. been drinking it since i was a teen while swimming in it ... big lake a few miles away and drank a lot of that water too while tubing and water skiing ... i know of a open well at where i hunt , was drinking that from the bucket on the rope since in was 6 .. never had a issue ..
If there are no medical facilities available, I'd prefer to dribble some bleach in my drinking water that I'm pretty sure is already clean (or boil, or filter, etc.), rather than take a chance of bleeding out of my ass until I died.
