Boiling is the superstar of natural water purification. Bring water to a rolling boil for just one minute. That’s it. The heat literally fries E. coli cells into oblivion. Think of it as a tiny sauna they can’t escape.
Fun twist: Boiling also kills 99.9% of other nasties. But don’t let it boil dry. You’ll end up with a scorched pot and no water. That’s just sad.
