Just read this on another forum and with the source listed I was surpised...

"According to the Wilderness Medical Society, water temperatures above 160° F (70° C) kill all pathogens within 30 minutes and above 185° F (85° C) within a few minutes. So in the time it takes for the water to reach the boiling point (212° F or 100° C) from 160° F (70° C), all pathogens will be killed, even at high altitude."

Source: OA Guide to Water Purification

Good to know in case the zombies attack and drinking water is needed after skull exploting fun is on standby.

That's actually a major point in survival manuals and courses. Don't waste fuel (And water) by boiling water for 10 minutes, it's pathogen free as soon as it reaches a boil.

On the other hand, no amount of boiling will rid water of chemicals and waste. For that you need a filter.

(Of course, FEMA, disaster geniuses that they are, recommend 1 full minute at a boil.)

I've boiled water to drink. No matter how clear it looks it still tastes gross. At least it won't give you the trots though.

I have a nice pump filter, and I bring lots of Propel powder, because the water tastes flat after being filtered. (Ah, who am I kidding, I don't like water without flavoring. Yucky!)

I believe the opposite would be true as well - cold water not being able to support pathogens, though I suppose they could just be dormant...

I asked my dad, he froze some skanky dishwater and said "drink it, it's safe." I think his point would be the freezing just makes the particles not swim as fast. And that he has been looking for subtle ways to kill me for years.

It'd have to be really cold to kill off all the bacteria. As in, a lot colder than just being frozen. The kind of cold you wouldn't be able to achieve in a survival situation.

more thinking that bacteria can't grow in cold water so it is more safe than the puddle sitting in the sun ;)
