Aqua Cura

 is a fake version of Aqua Pura in the Fallout 3 add-on Broken Steel.

It is produced by the ghoul Griffon by switching Aqua Pura with irradiated water to sell to the ghouls in Underworld. He would then sell the real Aqua Pura to people the Brotherhood of Steel won't give it to, such as the Raiders and Brotherhood Outcasts, to increase his profits.

Griffon also tries to increase his profits on the water by telling the ghouls it has effects that will benefit them (which it does because it heals them with the radiation, but it also furthers their "ghoulification".)

Location

 * Several are found in boxes on/right of the table next to Griffon.
 * It can be bought from Griffon (which costs 10 caps)
 * 30 can be found in Griffon's bottling operation (which is in the Museum Authority Building).
 * In the Holy Light Monastery.
 * Dozens can be found in the Citadel.

Behind the scenes

 * Selling quack cures with latin-sounding names and accompanied by a sense of showmanship is an American tradition.
