In a survival situation, there are simple disinfection methods to use, whether you have power or not. This is handy information to know in case you're stuck after a storm without water, and the same techniques will prepare snow for drinking too.
You can usually drink rain straight from the sky, but if you're collecting and storing it, you'll want to disinfect rainwater for drinking and cleaning. Fortunately, there are simple disinfection methods to use, whether you have power or not. This is handy information to know in case you're stuck after a storm without water or you're out camping. The same techniques can be used to prepare snow for drinking, too.
1) Boiling - Reduce pathogens by boiling water for 1 minute at a rolling boil or 3 minutes if you're at an altitude greater than 2,000 meters (6,562 feet). The longer boiling time at high altitude is because water boils at a lower temperature. The recommended duration comes from the Centers for Disease Control (CDC). If you store freshly boiled water in sterile containers (which can be boiled) and seal them, the water will remain safe indefinitely.
2) Bleach - For disinfection, add 2.3 fluid ounces of household bleach (sodium hypochlorite in water) per 1,000 gallons of water (in other words, for a small volume of water, a splash of bleach is more than sufficient). Allow 30 minutes for...Continue reading...
