The Mojave Wasteland has multiple natural sources of pure, non-radioactive water, and as a result, the Courier encounters clean water more often than in the Capital Wasteland, where most of the water is contaminated and radioactive. When playing in Hardcore mode, purified water is a more "refreshing" drink with respect to Dehydration than alcohol or soda, as they actually worsen Dehydration.

- Cactus water is a crafting recipe which enables the player character to collect purified water from desert plants.
- Mass purified water yields four units and can be distilled from five units of dirty water by using surgical tubing and two glass pitchers.

- ¹ Materials are not consumed and are returned to the player character after use.
- Purified water can be bought from several merchants, including Tapper, the Kings member who guards the water pump in Freeside, Lupe at the Grub n' Gulp rest stop, and William Farber, the NCR chef in Camp McCarran. The player character can also fill most empty bottles at the Sink at Big MT to create purified water.

Behind the scenes
Each bottle of purified water features the text "H²O" handwritten on the label on the side of the bottle. This format is incorrect (at least according to IUPAC nomenclature), as in 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.
