The landfill is a hollowed-out mound with entrances from the east, west, and south. Approaching one of these entrances will trigger a spawn of 12 or more mole rats coming in waves of two or three at a time. Inside the mound to the east is a toolbox and a steamer trunk.
To the northeast, on top of the mound, there are two containers (a desk and a cooler) with randomized loot. To the southwest are a small shack with some junk inside, Nuka-Cola machine by the door and a dumpster behind.
- A leveled set of power armor at the bottom of the lake, southeast from the landfill, near the vertibird that can be seen from the surface.
- Usually a settler spawns at the landfill and fights the mole rats. If spoken to, they will reward the Sole Survivor with 50 caps for helping them fight off the rats, then walk away towards Covenant. It is also possible to find the settler already dead.
- Unlike most mole rat infestations, the initial wave of this one generally starts above ground, clustered near the building, and vulnerable to explosive attack.
- There is a shack due west of the landfill with some radioactive barrels and a radscorpion that could prove challenging to low level characters.
- Placing a mine on the spot where the radscorpion would spawn will cause it to detonate immediately and damage the player even if the enemy has not spawned yet.
- Companions will make remarks about the smell while in the area:
- If Strong is traveling with the player character, he may comment on the smell stating it "smells like home."
- If Nick Valentine is traveling with the player character, he will comment on the rotten smell.
- If Hancock is traveling with the player character, he will comment "some places, you just wish they'd nuked them harder."
- If Preston Garvey is traveling with the player character, he will comment "Wish I had brought a gas mask."
- If Piper is traveling with the player character, she will comment "it smells rank in here."
- If Cait is traveling with the player character, she will comment that "it smells like the bathroom after Salisbury Steak night."
- If Ada is traveling with the player character, she will comment "Now stored in my data banks. This must be the meaning of the term known as 'thoroughly disgusting.'"
- If Codsworth is traveling with the player character, he will remark "What a stench this place must generate!" and/or "I dare say my sensors are picking up quite the smell, I, I can't imagine it must be very pleasant for you sir/ma'am!"
- If Curie is traveling with the player character, she will remark "this offends my sensibilities."
- If Danse is traveling with the player character, he will remark that "these noxious fumes are quite revolting."
The rotten landfill appears only in Fallout 4.
- The rotten landfill will respawn all loot found within containers located there, immediately upon exiting and re-entering the cell it is located in. [verified]
- Sometimes not all of the mole rats seem to spawn, preventing the location from being cleared and the settler from giving the player a reward and walking away. [verified]
- Sometimes two settlers spawn at this location, but only one of them has the special dialogue and gives the reward. The other settler only has generic dialogue. [verified]
