Water Beggars

 refers to an unmarked and repeatable quest in Fallout 3.

A lot of Wastelanders need Purified Water. Giving them this gives you positive Karma (+50). Denying them water causes them to die at the next map change, even if they were given Purified Water before. They do not die if you do not explicitly tell them to find their own water, however, and their death incurs no Karma loss for you.

Since two of the beggars are outside player houses, they can easily farm good karma using water generated by their Mr. Handy. You can also gather Aqua Pura, which is made available with the Broken Steel DLC pack, and give them this. There are hundreds of bottles lying around the Citadel, and this is a much easier way of farming good karma than getting it off Wadsworth or Godfrey.
