How To Treat and Store Water For An Emergency
Treating potentially contaminated water in an emergency
Quantities of bleach used to treat water for emergencies
Amount of Water | Amount of bleach to add to clear water | Amount of bleach to add to cloudy water |
---|---|---|
1 gallon | 8 drops | 16 drops |
5 gallons | � teaspoon | 1 teaspoon |
55 gallons | 2 tablespoons | � cup |
After you add the bleach, thoroughly mix by stirring or shaking the container. Let the water stand for 30 minutes before using. A slight chlorine odor should be noticeable in the water, if not, add another dosage of bleach and allow the water to stand another 15 minutes before using.
The water can also be treated with the use of water purification tablets which can be purchased at most outdoors or sporting goods stores. Follow the directions for use on the package you purchase.
Treat only enough water to meet your needs for 48 hours at a time. There is an increased chance of recontamination if the treated water sits for more than 48 hours. Refrigeration will also help avoid recontamination.
Note: Most home water filters are meant for water that is already microbiologically safe. Using these filters during a "boil water notice" will not guarantee the safety of the water. Replace any filter cartridges after the boil water notice has been lifted to insure your filter is not contaminated.
