In a recent article for The Casper Star Tribune, senior NOLS instructor Marco Johnson explains the top four methods for water purification in the backcountry and when to use them. Depending on your budget and the type of trip you’re taking, Marco recommends different strategies ranging from simply boiling the water to using chemical or UV treatment.
"No matter where you go, you either need to bring enough water with you (which is often nearly impossible) or figure out how to clean what you find along the way…
