Aqua Pura

 is literally "Pure Water" that is available once the add-on Broken Steel is installed, and the quest Take it Back! is completed.

Drinking the water after choosing to infect it with the Modified FEV will result in a player debuff (-2 STR and -1 INT) and, if you drink too many, you will die (this is usually any more than two), so be careful. The reason for this danger is the fact that the Lone Wanderer was born in a Vault and thus isn't immune against the Modified FEV.

Appearances

 * Aqua Pura only appears with the Broken Steel add-on.

Behind the scenes

 * Aqua Pura is a brand of mineral water in the United Kingdom as well as a spring water brand offered in the United States.
 * Aqua Pura means "Pure Water" in Latin.

Bugs

 * Giving any amount of Aqua Pura to Water Beggars will result in their death at the next map change, regardless of whether or not the Aqua Pura contains Modified FEV. (confirmed all platforms)


 * Sometimes after drinking Aqua Pura a message will appear saying that "Aqua Pura has worn off". This is like when a chem wears off but there were no effects to begin with. This message may appear at random times, days after drinking Aqua Pura. (Not a bug really, it wears off the debuffs if infected. It just isn't removed from the pure version)(confirmed all platforms)


 * NPCs will use this as an aid item during firefights. It will have the same effects on them if there is Modified FEV added. However, NPC's drinking it will trigger the script that attributes the negative effect to you. In essence, if separate NPC's drink many infected Aqua Puras, the script will kill you instead of them.
