Ofcourse not all is black or white. I am also not a big fan of drinking water from the first creek or river I pass by. There are more save méthodes to do this I believe. I personally don't have a problem with drinking small amounts of water from a small waterfall or something and I eat raw eggs regularly by the way (only from my own chickens). I never got sick from it and I have a great immune system. Buth again, I would never try water that has been standing still in some creek.
The guys who sell that water, in my eyes they are criminals. They are taking advantage of just another hype that can be dangerous if some foul thinks he can earn as much as them selling water from some dirty creek to people who don't know any better.

I feel bad for the Americans that don't have access to clean water. Here in Belgium everyone has acces to clean water and we all just take it for granted.
