You're thirsty, aren't you America? Not for knowledge or power, no. I'm not speaking metaphorically. You're thirsty for clean, fresh water. Hmm? Water is the foundation of life. But here, in the Capital Wasteland, indeed the entire country, water is polluted. Irradiated. Deadly.— John Henry Eden

Water is a consumable item in Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76 and Fallout: The Board Game.


Dirty water

Dirty water is the most common type of water found in the wasteland. It is drawn from the tainted lakes, rivers, and puddles. Unlike purified water, this will give radiation, which can be cured for a fee by a doctor or through RadAway.

Purified water

Purified water is water that has been purged of any radiation, making it a safe to consume. It is not quite as common in the Capital Wasteland as it is in the Mojave and the Commonwealth, often being found in first aid kits and more advanced settlements.

Aqua Pura

Aqua Cura

Aqua Cura is regular irradiated water disguised in an Aqua Cura bottle that Griffon sells in Underworld to cure a plethora of illnesses that ghouls often suffer from. Griffon also takes the real Aqua Pura and sells it to other wastelanders at an inflated price.

Cactus water

Irradiated water

Irradiated water is a variant of dirty water in Fallout: New Vegas. It has been even exposed to stronger levels of irradiation and thus it irradiates the drinker three times as much as dirty water. A limited amount of bottles can be found and they are mostly located in highly irradiated areas.

Boiled water

Gameplay article: Fallout 76

Boiled water is craftable water in Fallout 76.


  • In Fallout 3 and Fallout: New Vegas, drinking from standing water such as lakes, rivers, and puddles, can restore between 2 and 30 HP.
  • In Fallout 4, drinking such water will restore some HP as well as increase the irradiation level of the player character.

Behind the scenes

Each bottle of purified water features the text "H2O" handwritten on the label instead of "H2O." This format is incorrect (at least according to IUPAC nomenclature), as chemical formula numbers are written in subscript (Xy), not superscript (Xy).
