Water

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

Background
Water is the driving force behind all wasteland communities; no water means no community. Many industrialized cities have developed systems that scrub radiation from water, making purified or "clean" drinking water, while other smaller towns often have to resort to drinking irradiated or "dirty" water where they can find it.

Dirty water


Dirty water is the most common water in the game, and is drawn from the tainted lakes and rivers. Unlike purified water, this will give you radiation, which can be cured for a fee by a doctor or by using RadAway.

Purified water


Purified water is water that has been purged of any radiation, making it one of the only "clean" sources of water in the wasteland. It is not quite as common in the Capital Wasteland as it is in the Mojave, but the water is still rather common, often being found in first aid boxes and more advanced settlements.

Aqua pura


Aqua pura is purified water that has been bottled from the water being taken in from the Tidal Basin and purified at Project Purity.

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.

Rushing water


Rushing water is a drink created by lacing purified water with Jet, giving an energy rush without any chance of addiction. While under the effects of rushing water, it also heals the same amount as purified water.

Behind the scenes

 * Each bottle of purified water appears featuring the text "'H²O" hand written on the label on the side of the bottle. This format is incorrect (according to IUPAC nomenclature), as chemical formula numbers are written in subscript (Xy) and not in superscript (Xy). If read literally, the chemical formula H²O would mean there is one hydrogen and one oxygen isotope that contains two neutrons (instead of the standard eight). This would leave the oxygen extremely unstable and radioactive with a half life that would be so small that it would not be measurable.
