This is the necropolis Vault section of the map of the wasteland presented by:
When in the Nec Vault you will come across glowing ghouls. Becareful, they can radiate you. There is really no place to go but the command center unless you want to kill all of the glowing ghouls. In the command center you will find a working computer, use it and you will get the water-chip! And a level. Then go straight to Vault-13 and your done with that quest.
