One minute boil? The truth behind flood water safety
Boiling Water Safety
Learn the exact boil time that makes flood water safe, and the final tip that matters most.
One minute boil
At sea level, a rolling boil for one minute kills the germs that cause typhoid, cholera, hepatitis and everyday diarrhoea.
High altitude rule
If you're above 2,000 metres, keep the rolling boil for three minutes to be safe.
Boiling temperature
Water reaches a full boil at 100 °C at sea level, hot enough to denature proteins in germs instantly.
How to boil safely
Start with the clearest water you have, use a clean pot with a lid, bring it to a full rolling boil, big bubbles that keep breaking the surface even when you stir, and then time one minute, or three minutes up high. Let the water sit a minute after boiling before you pour, to let the biggest bubbles settle.
Steaming not boiling
Remember, steaming isn’t boiling; tiny bubbles at the pan’s bottom don’t count, wait for the big ones.
After the boil
The real risk comes after the boil. Pour water from a container with a spout instead of scooping, keep the storage vessel clean and covered, and never top up old water with fresh without rinsing first. Use a narrow-necked pitcher or a tap-style dispenser; avoid scooping with a cup that touches the water surface.
What boiling can't remove
Boiling kills germs but does nothing for chemicals like pesticides, fuel, or heavy metals. If the water smells oily or looks rainbow-colored, choose bottled or trusted supply instead.
The one key habit
The single most important habit is to keep the water at a full rolling boil for at least one minute, three minutes up high, then store it in a clean, covered container to avoid re-contamination.
