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, this will give you 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 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 without a canteen to find adequate quantities of purified water.
