The fact is, with a water temperature of 160 to 165 degrees F (74 C) it takes just half an hour for all disease causing organisms to be inactivated. At 185 degrees this is cut to just a few minutes. By the time water hits its boiling point of 212 F (100 C) - plus or minus depending upon pressure or altitude - the water is safe. Even at high altitudes the time it takes for the water to reach a rolling boil and then cool means you can safely drink it.
Lacking a thermometer to measure water temperature, you only need to get your water to a rolling boil. By that point you know the water is hot enough and that the disease organisms in your water were destroyed quite some time earlier. End of story, turn off the heat. Stop wasting fuel. Let the water cool down. Your water is safe to drink!

Certainly good advice.

I like that website, and I use it for a lot of purposes.
On Best Defense: Survival Michael Janich gave the information that bringing water to a boil is enough to kill all organisms. No boiling time needed, just get it to a boil.

I have utilized these guys for a few items. Safecastle is a another resource.

Water boils at 212 F.
I believe it is not coincidental that protein coagulates at that same temperature. Think of the difference between a raw egg and a hard boiled one.
But I seem to remember something that could form a "cyst" or whatever and protect it self...but can't find a reference for it.

You might be thinking of Cryptosporidium.
Fecal/oral disease - resists chlorine. UV sensitive though and boiling water for 1 minute kills it.

Yeah..I found a couple of things that were resistant to boiling water for 1 minute.
And others that were even more resistant but were not waterborne or were not dangerous.

Here is a place for food, canned ammo, and other tools and items.
