| ||For the various forms of water that appear in the Fallout series, see Water.|
The Mojave Wasteland has multiple natural sources of pure, non-radioactive water, and as a result the player encounters clean water more often than in Fallout 3, where most of the water is radioactive.
Purified water can also 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 can also fill most empty bottles at The Sink in the Old World Blues add-on.
- Cactus water is a crafting recipe which enables the player to collect purified water from desert plants,
- Mass purified water yields 4 units and can be distilled from 5 units of dirty water by using surgical tubing and 2 glass pitchers (the two later being reusable as not being consumed in the process).
Cactus water (1)

- Dirty water (same effects, +6 radiation)
- Irradiated water (same effects, +16 radiation)
- Rushing water uses purified water model and has similar effects. Lonesome Road (add-on)
- Drinking from a clean water source, such as the pumps at Goodsprings source or Lake Mead, or water tabs or toilets, (i.e. fixed installations providing running water as opposed to consumables) will remove 200 points from the Dehydration meter.
- The player, after retrieving the Sink personalities' upgrades, has the option to receive purified water from the Sink.
Behind the scenesEdit
Each bottle of purified water appears to feature the text "'H²O" hand written 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.
