• DC Water issues Boil Water Advisories to protect public health when there is a water quality risk.
• Should a loss in pressure occur, DC Water will issue a Boil Water Advisory for the impacted area until water quality testing can confirm the water is safe.
• DC Water staff would sample and test the water while crews flush the distribution system with clean water to get rid of any potentially contaminated water.
• An advisory would remain in effect until two rounds of sampling and testing confirm the water is safe.

• A pressure change increases the potential for contaminants to enter the water system.
• Although the chance of contamination is slim, we err on the side of caution and issue the advisory until we can confirm that water quality is not compromised.

• The impact area is based on elevation, so if customers were below the elevation that we established as safe, they were not at risk for any water quality impact.
• Elevation varies significantly throughout the city and DC Water used conservative elevation boundaries to determine the area of impact.

As always, if you experience unexpected illness, please consult your healthcare provider.

Consumer Information: EPA provides information and guidance about drinking water quality, emergencies, contaminants, public health issues, and treatment and storage.

• Fill a pot or kettle with water.
• Heat the water until bubbles come from the bottom of the pot to the top.
• Once the water reaches a rolling boil, let it boil for 1 minute.
• Turn off the heat source and let the water cool.
• Pour water into a clean container with a cover for storage.

If tap water is clear:

• Use bleach that does not have an added scent (like lemon).
• Add 1/8 teaspoon (8 drops or about 0.75 milliliters) of household liquid bleach to 1 gallon (16 cups) of water.
• Mix well and wait 30 minutes or more before drinking.
• Store disinfected water in a clean contain with a cover.

If tap water is cloudy:

• Filter through a clean cloth
• Use bleach that does not have an added scent (like lemon).
• Add 1/4 teaspoon (16 drops or 1.5 milliliters) of household liquid bleach to 1 gallon (16 cups) of water.
• Mix well and wait 30 minutes or more before drinking.
• Store disinfected water in a clean container with a cover.

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

• Use bleach that does not have an added scent (like lemon).
• Add 1 teaspoon (64 drops or 5 milliliters) of household liquid bleach to 1 quart (32 ounces, 4 cups, or about 1 liter) of water.
• Pour this into a clean storage container and shake well, making sure that the solution coats the entire inside of the container.
• Let sit at least 30 seconds, and then pour out solution.
• Let air dry OR rinse 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.

• You may choose to use bottled water if it is available.

To improve the taste you can:

• Pour cooled water back and forth from one clean glass into another to add air to the water.
• Let the water stand for a few hours.
• Add a pinch of salt to each quart of boiled water.

Do not use water from any appliance connected to your water lines. This includes water and ice dispensers in your refrigerator/freezer.

• Use boiled or bottled water to make coffee and ice.
• Filters do not remove or kill bacteria or viruses.
• When the boil water advisory is lifted, consult the owner’s manual and sanitize appliances.

• 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.

• Wash fruits and vegetables with cooled, boiled water or bottled water.
• Bring water to a rolling boil for one 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.

• Breastfeeding is best. Continue to breastfeed. If breastfeeding is not an option:
• Use ready-to-use formula, if possible.
• Prepare powdered or concentrated formula with bottled water. Use boiled water if you do not have bottled water. Disinfect water for 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.

• Dishwashers are safe to use if the water reaches a temperature of at least 160°F or if the dishwasher has a sanitizing cycle.

To wash dishes by hand:

• Wash and rinse the dishes as normal using hot water.
• In a separate basin, add 1 teaspoon of unscented household bleach for each gallon of warm water.
• Soak the rinsed dishes in the water for at least 1 minute.
• Let the dishes air dry completely.

• Contamination has not yet been confirmed. Most people who drink this water will not get sick. If you do get sick, the symptoms are similar to food poisoning: nausea, diarrhea, cramps, and possibly a mild fever.
• These symptoms can be caused by unrelated illness; they are not only caused by microbes in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice.
• People at increased risk should seek advice about drinking water from their health care providers. 

• The most important thing to do is avoid dehydration. Drink plenty of fluids and avoid drinks with caffeine, such as soda, coffee, and tea.
• Again, these symptoms can be caused by unrelated illness; they are not only caused by microbes in drinking water.
• If you are concerned about your health or the health of a family member, contact your health care provider.

Pets can get some of the same diseases as people. It is a good idea to give them boiled water that has been cooled.

Most germs that infect people do not infect reptiles or fish. If your water system is using more chlorine or changing disinfection, be cautious about changing the water in your fish tank or aquarium. Contact your local pet store or veterinarian for more advice.

You can use tap water for household plants and gardens.

No. Do not use tap water to brush your teeth. Use boiled or bottled water.

Yes, it is safe to take a bath or shower, but be careful not to swallow any water. Use caution when bathing infants and young children. Consider giving them a sponge bath to reduce the chance of them swallowing water.

Yes, you can shave as usual.

Yes, it is safe to do laundry as usual.

• Review the interactive map on dcwater.com, or calling the 24-Hour Command Center at (202) 612-3400.
• Run your cold water taps for 10 minutes if you did not use water during the advisory to replace water sitting in pipes with fresh water from the main. Water quality can decline when it sits for extended periods of time in pipes. If you used water consistently to flush the toilet, shower, or wash your hands, this action is precautionary, not necessary.
• Consult the owner’s manual to find out how to sanitize appliances and home filtration systems if used during the advisory.
