Before drinking it you might want to wave a Geiger-counter over it. I was deployed in the arctic of Norway and we were advised not to use the snow for water due to it being contaminated during the Chernobyl incident.
Just the thing to add that extra BUZZ......
theres water bottled at a geyser in Calistoga CA...which is the best stuff Ive ever drunk. First encountered it in 1971 and have never found anything better. It tastes right!
