I met a German man while touring in Eastern Utah. As he filled up my water bottles in this dry land he quizzed me. “How come when I come close to cities in the United States the water tastes like (here he stumbled trying to find the right word and finally blurted out) . . . a swimming pool?”
How, if at all, do folks treat their water while on tour?
I carry two water filter bottles. A Clear 2 Go for all municipal and biologically safe water, mostly to clean up the chemical taste, and a Katadyn My Bottle for most surface water. Basically, I filter nearly every drop I drink.
