Scientists will test drinking water supplies to make sure they are safe. Until those results are available, bottled water is the only water that is free of contamination.

Radiation IconBoiling tap water does not get rid of radioactive material. You should have bottled water in your emergency supplies.

  • You can drink water, juices, or other drinks in sealed containers. Drinks in your refrigerator or freezer are also safe to drink. The package protects the liquid inside from radioactive material.
  • If you think the container or package may have radioactive material on the outside, use a damp cloth or clean towel to wipe it off before opening it. Put the used cloth or towel in a plastic bag or other sealable container and place the bag in an out-of-the-way place, away from other people and pets.
  • Water in other containers in your home, such as a toilet tank or hot water heater will also be free of radioactive material.
    • You can still use tap or well water for cleaning yourself and your food.
      • Even if the tap water is contaminated, public health officials may recommend that you drink bottled water instead of tap water.
      • You can still use tap water for decontamination. Any radioactive material that gets into surface water or ground water sources will be diluted to very low levels by the water and will be safe to use for washing skin, hair, and clothing.
