Boil Water Advisory in Metro Atlanta: What to Do Right Now
Boil or use bottled water until lifted
Do this now
- Stop drinking straight from the tap. Use bottled water, or boil your tap water first, for drinking, cooking, food prep, making ice, mixing baby formula and brushing your teeth.
- To boil: bring the water to a full rolling boil and keep it there for 1 minute. Let it cool before you use it. If it looks cloudy, let it settle or pour it through a clean cloth, paper towel or coffee filter first. Store it in clean containers with tight covers.
- Skip the water and ice from your refrigerator door. And boil water even if it went through a home filter or a filter pitcher.
- Check that the advisory covers your address. Each utility issues its own, so a City of Atlanta advisory does not cover Gwinnett County water customers. Look at your utility's notice and map. If you lost water or pressure but your address is outside the area described, the City of Atlanta recommended in a 2019 advisory that you follow the same precautions. If your water was off, boil it once service comes back.
- Feeding a baby? Breastfeeding is safest. If you use formula, ready-to-feed formula is the next safest choice. If powdered formula is all you have, mix it with bottled or boiled water, and clean bottles and feeding items with bottled, boiled or treated water and soap before each use.
- Dishes: use disposable plates and cups if you can. A dishwasher is generally fine if it has a sanitizing cycle or a final rinse of at least 150°F. By hand, wash and rinse in hot water as usual, then soak for at least 1 minute in a separate basin with 1 teaspoon of unscented household liquid bleach per gallon of warm water, and let everything air dry completely.
- Showers are fine if nobody swallows the water. For babies and young children, consider a sponge bath so they do not swallow water. Laundry can go on as usual. Give pets bottled water or boiled water that has cooled.
- When your utility lifts the advisory, flush your plumbing before normal use: fully open the sink and shower faucets on each floor, for as long as your utility's notice says. Throw out any ice left in your ice maker, then let it make a new batch and throw that out too. Some agencies say to toss the first two new batches.
Can you fix it yourself?
Your water utility issues the advisory and tests the water, and the Georgia Environmental Protection Division has a role in when it ends. DeKalb's December 2022 advisory was lifted after EPD reviewed microbiological test results and authorized it, and in a 2019 advisory the City of Atlanta said EPD would tell it when the advisory could be lifted. Nothing at your sink fixes the water in the main. What you control is boiling, using bottled water and flushing once it is over. The plumbing job that can follow comes after a freeze: Clayton County's water authority warns that customers who had low pressure or no water may find leaks once service is restored, and should contact a plumber as soon as possible.
When to call a pro
- Your water utility, to confirm your address is in the advisory area. City of Atlanta customers: ATL311 at 404-546-0311. Other counties: the number on your water bill or the advisory notice
- Your utility right away if the water has a bad or chemical smell or an unusual color. Boiling does not make water with fuel or chemicals safe, so use bottled water and ask your health department
- A plumber if you find a leak after a freeze once pressure comes back, and keep that water off until it is repaired
- 911 for extreme flooding or anything else that poses a safety hazard, and report a broken water main to your utility right away (City of Atlanta: 404-546-0311)

What to ask the plumber
- Is my address inside the advisory area, and where is the current map?
- When it is lifted, how long should I run my faucets, and should I flush my water heater too?
- Do I need to change my refrigerator or under-sink filter cartridge afterward?
- Now that pressure is back after the freeze, can you check my lines for leaks, including the ones I cannot see?
Questions we hear
Can I do laundry during a boil water advisory?
Yes. CDC says it is safe to wash clothes as usual. Showers are fine too, as long as nobody swallows the water, and CDC suggests a sponge bath for babies and young children. For handwashing, CDC says tap water and soap is fine in many cases, but follow what your local officials say.
How long does a boil water advisory last?
Until testing shows the water is safe, so there is no set length. Clayton County's water authority explains that Georgia EPD requires an advisory once system pressure drops below 20 psi, and that it lasts until pressure is back to normal and required testing confirms the water is safe. Some recent ones were short: the City of Atlanta lifted a downtown advisory on May 23, 2026, the day after it was issued, and lifted one issued September 29, 2024 on October 1. DeKalb's freeze advisory began December 26, 2022 and was cancelled December 28.
The advisory was lifted. What do I do now?
Flush first. After a 2020 advisory, Gwinnett County told customers to flush the plumbing before normal use by fully opening the sink and shower faucets on each floor. Throw out any ice left in your ice maker and at least the first new batch; some agencies say the first two. If you see air in the lines or discolored water as pressure comes back, Clayton County's water authority says running cold water for a few minutes typically clears it up. If the water is still discolored after the advisory ends, report it to your utility. Agencies give different advice on filters and water heaters, so ask your utility.
Why do freezes cause boil water advisories?
Freezes break pipes and water mains. Clayton County's water authority says the December 2022 freeze caused frozen pipes and main breaks, with low pressure and outages, and DeKalb crews were repairing nine water main breaks while its advisory was in effect. When pressure drops below 20 psi, Georgia EPD requires the utility to issue a boil water advisory as a precaution.
