How Long to Boil Water So It's Safe to Drink - It's a critical issue when hiking in the wilderness or traveling in some foreign lands. Filters and purifiers can work well, HOWEVER:
The ONLY 100% reliable method for killing waterborne pathogens is boiling.
According to the Wilderness Medical Society...
- water temperatures above 160° F (70° C) kill all pathogens within 30 minutes and
- water temperatures above 185° F (85° C) kill all pathogens within a few minutes.
So by the time water temperature goes from 160° F (70° C) to the boiling point (212° F or 100° C), , even at high altitude.
One of the funniest things I've ever received by email. Truly wish I knew who wrote it.
Dear Mom & Dad,
We are having a great time here at Lake Typhoid. Scoutmaster Webb is making us all write to our parents in case you saw the flood on TV and worried. We are OK. Only 1 of our tents and 2 sleeping bags got washed away. Luckily, none of us got drowned because we were all up on the mountain looking for Chad when it happened. Oh yes, please call Chad's mother and tell her he is OK. He can't write because of the cast. I got to ride in one of the search & rescue jeeps. It was neat. We never would have found him in the dark if it hadn't been for the lightning. Scoutmaster Webb got mad at Chad for going on a hike alone without telling anyone. Chad said he did tell him, but it was during the fire so he probably didn't hear him...
