For the various forms of water that appear in the Fallout series, see Water.

Dirty water is a consumable item in Fallout: New Vegas.


Dirty water is the most common water in the game, and is drawn from the tainted lakes and rivers of the Mojave Wasteland. Unlike purified water, drinking dirty water will induce moderate radiation, which can be cured for a fee by a doctor, or by using RadAway.

Consuming contaminated water is much more irksome than in Fallout 3, because of the lack of the My First Infirmary. However, with Hardcore mode enabled, it may be a necessary consumable, as it can be difficult for players early in the game to find adequate quantities of purified water.

  • Dirty water differs in appearance from purified water. Dirty water is labeled "WATER," while purified water is labeled "H²O"; the bottle is also grimier. The Pip-Boy 3000 icon for both is the same, however.
  • Dirty water can be purified in bulk at a campfire.
