WATER PURIFICATION#

Use regular household bleach, which the only active ingredient is ‘sodium hypochlorite’.

Having said that, one best way to purify water for drinking is to boil it for 1 minute.
Once the water has reached a rolling boil, it has become safe to drink.

Note that if the water source had been contaminated with chemicals, boiling it or otherwise treating it will NOT assure that the chemical is removed.

Know your water source as best you can.

UPDATE: For many years, regular bleach contained a concentration of 5.25% – 6% sodium hypochlorite. Newer ‘regular’ liquid bleach may contain a concentration of approximately 8% sodium hypochlorite (about a third more than the original bleach formula).</br></br>
Mix the following amount of bleach with water, and wait 30 minutes for it to work. The water should have just a ‘hint’ of chlorine smell.
WATER – BLEACH RATIO FOR PURIFYING DRINKING WATER

(5-6% Sodium Hypochlorite)
numbers are ’rounded’

1 Quart water, 2 drops bleach
1 Gallon water, 8 drops bleach
5 Gallons water, 1/2 teaspoon bleach
10 Gallons water, 1 teaspoon bleach
50 Gallons water, 5 teaspoons bleach

(8.25% Sodium Hypochlorite)
numbers are ’rounded’

1 Quart water, 1 drop bleach
1 Gallon water, 5 drops bleach
5 Gallons water, 3/8 teaspoon bleach (or three 1/8th teaspoons)
10 Gallons water, 3/4 teaspoon bleach
50 Gallons water, 3.5 teaspoons bleach

HOW TO TELL IF YOUR FOOD IS STILL GOOD AFTER AN EVACUATION#

For those of you that are evacuating from the coast, I just heard a great tip. It's called the one cup tip. You put a cup of water in your freezer. Freeze it solid and then put a quarter on top of it and leave it in your freezer. That way when you come back after you've been evacuated you can tell if your food went completely bad and just refroze or if it stayed Frozen while you were gone. If the quarter has fallen to the bottom of the cup that means all the food defrosted and you should throw it out. But if the quarter is either on the top or in the middle of the cup then your food may still be ok. It would also be a great idea to leave this in your freezer all the time and if you lose power for any reason you will have this tip to fall back on. If you don't feel good about your food, just throw it out.
