Long term water purification

[Luci_ferson]

distilling water is unadvisable as it removes the micro nutrients (minerals)
as for the boiling and the 65oc etc. not all germs die at 65oc most will but not all.
milk pasteurisation is different.
milk is technically sterile the moment it comes out. same as breast milk.
I believe the 65oc of pasteurisation is only to remove pathogens that the mother could be carrying.
things like staphlococsaurus or however it is spelled will not die at 65oc neither will many others.
but that's unlikely to be in a cow.
nastys can get into water supplies.
id definitely boil risky water before drinking it, and not just heating it to 65oc for 30 mins.
also without a thermom it is difficult to know it is at 65oc for the whole time.

its easy to see if something is boiling.

Obviously I could be wrong (I often am) but I wouldn't take the risk, and I don't have a thermom, even if I did its likely to get broken.

the pathogen that causes legionaires disease is found in stagnant water. im not sure if 65oc would kill that one either, (maybe it does but im not lucky )
