But... but... Ralph Cutter proudly boasts that he drinks straight from the source with no filtering - it's a simple pleasure for him - and he's "the man" right?

I'll let Ralph drink all the untreated water he likes.
I used to believe like him, that is until I started doing water quality work in the backcountry.
The thought of drinking * tainted water doesn't really appeal to my tastes, even if it looks perfectly good. As ole Clint used to say, "do you feel lucky"....
And my biggest complaint of the referenced "study" is the author pretty much ignored the threat of all the other pathogens that you can ingest whilst drinking untreated water and the fact that simple filtering of the water removes the threat from most all of them (with the exception of viral pathogens).
