They mention having a source of water in 3.
In 1 they drink (water) and eat (people). If you take their chip and don't repair their pump, they die.

Fallout 2 also established ghouls were all going to die inside 20 years. And a lot of other lore, including Star Trek time travel breaking the water chip, the president is called Dickdickson, FEV makes talking plants and animals, wanamingos are aliens from space, there's a rainbow patrol of gay people, and so on and so forth. Half of which is no longer canon, the other half is equally fucking retarded.
I can't remember if it's also the one with LGBTQI+ representation of a dog because a raider says "I think my dog's gay".
There's also Set's son. He was irradiated as a teenager, or a child, a definitive age isn't given unless I'm mistaken, and he's now an old man in an old folk's home... in the same series that has the ageless fridge child.
