...And Not a Drop to Drink

 is a challenge in Fallout: New Vegas.

Requirements
To complete this challenge, the player must consume 100 water items. Water items include bottled water, either purified or dirty. Unlike what the perk description suggests, drinking from an environmental water source does not count (Sink, River, Etc).

Effects
Adds the Camel of the Mojave Perk, granting +15% hydration from bottled water items.

Bugs
The game may give notification that the player has hit a milestone in the challenge, regardless of every drinking water or not.
 * Sometimes the challenge progress notification will not appear until the next load, it does appear to keep track however.
 * The number of times water drunk shows as zero on the Pip-Boy 3000, no matter how many times the character drinks. This is true in both regular and hardcore modes.

Behind the scenes
The name of this challenge is based on the ending of a quote from the poem, "Rime of the Ancient Mariner," written by the romantic poet Coleridge: "Water, water, everywhere, and all the boards did shrink; Water, water, everywhere, nor any drop to drink."
