Purified water Fallout: New California
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.

Variants[]

Dirty water[]

FO3 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[]

Fo4 purified water

Purified water is water that has been purged of any radiation, making it 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[]

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.

Drugged water[]

Fo4 dirty water
Gameplay article: Fallout 4

Drugged water is a pre-War variant that was drugged with sedatives by HalluciGen, Inc. It was used by HalluciGen as part of their test subject intake, and once it had taken effect the subject was then taken by lab personnel for testing.

Institute bottled water[]

Gameplay article: Fallout 4

Institute bottled water is a purified variant that is bottled and distributed by the Institute. It can be bought from the synth cafeteria worker.

Boiled water[]

Fo4 dirty water
Gameplay article: Fallout 76

Boiled water is craftable water in Fallout 76. It has been strained and heated over a fire. Although safer than dirty water, it is not as clean as purified water and still inflicts some radiation damage. Boiled water is instrumental in the crafting of many recipes, including teas, soups, and medicines.

Toxic water[]

Fo4 dirty water
Gameplay article: Fallout 76

Toxic water is highly irradiated water in Fallout 76. It can be collected from especially unclean water sources, typically ones that are brown and orange in color. It is the most unsafe of any water variant in the game, and cannot be boiled or purified.

Notes[]

  • 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).
