More flooding from heavy rain caused by climate change will undoubtedly mean that water supplies will be contaminated at times. To purify it:
Add 1/4 tsp of bleach to one gallon of water (8-16 drops)
Double it if the water is cloudy
Shake, let stand 30 minutes
Immediately after treating it should have a slight chlorine smell. If not, repeat
The smell goes away in a few days
Store the water in the dark
