What to do during a boil order:

•   Once the water reaches a rolling boil, let it boil for 1 minute.


•   Turn off the heat source and let the water cool.


•   Pour the water into a clean container with a cover for storage.


Disinfecting water

If you are unable to boil your water, disinfect it instead.


If tap water is clear:


•   Use unscented bleach (bleach that does not have an added scent).


•   Add 1/8 teaspoon (8 drops or about 0.75 milliliters) of unscented household liquid bleach to 1 gallon

(16 cups) of water.


•   Mix well and wait 30 minutes or more before drinking.


•   Store disinfected water in clean container with a cover.


If tap water is cloudy:


•   Filter water using clean cloth.


•   Use unscented bleach (bleach that does not have an added scent).


•   Add 1/4 teaspoon (16 drops or 1.5 milliliters) of unscented household liquid bleach to 1 gallon (16 cups) of water.


•   Mix well and wait 30 minutes or more before drinking.


•   Store disinfected water in clean container with a cover.


Remember that containers may need to be sanitized before using them to store safe water.

To sanitize containers:


•   Use unscented bleach (bleach that does not have an added scent).


•   Make a sanitizing solution by mixing 1 teaspoon (5 milliliters) of unscented household liquid bleach in 1 quart (32 ounces, 4 cups, or about 1 liter) of water.


•   Pour this sanitizing solution into a clean storage container and shake well, making sure that the solution coats the entire inside of the container.


•   Let the clean storage container sit at least 30 seconds, and then pour the solution out of the container.

•   Let empty container air dry OR rinse it with clean water that has already been made safe, if available. Never mix bleach with ammonia or other cleaners. Open windows and doors to get fresh air when you use bleach.


Water filters


Boil tap water even if it is filtered. Most kitchen and other household water filters typically do not remove bacteria or viruses.


Preparing and cooking food


• Wash all fruits and vegetables with boiled water that has cooled or bottled water.

• Bring water to a rolling boil for 1 minute before adding food to cook.

• Use boiled water when preparing drinks, such as coffee, tea, and lemonade

• Wash food preparation surfaces with boiled water.


Feeding babies and using formula


• Breastfeeding is best. Continue to breastfeed. If breastfeeding is not an option:

• Use ready-to-use baby formula, if possible.

• Prepare powdered or concentrated baby formula with bottled water. Use boiled water if you do not have bottled water. Disinfect water for baby formula if you cannot boil your water (see above for directions on how to use bleach to disinfect water).

• Wash and sterilize bottles and nipples before use.

• If you cannot sterilize bottles, try to use single-serve, ready-to-feed bottles.




•   Do not use ice from ice trays, ice dispensers, or ice makers.


•   Throw out all ice made with tap water.


•   Make new ice with boiled or bottled water.


Bathing and showering


Be careful not to swallow any water when bathing or showering.


Use caution when bathing babies and young children. Consider giving them a sponge bath to reduce the chance of them swallowing water.
