Figure out what Denom did to the crops

Figure out what Denom did to the crops was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios.

Background
Azkee is worried about the crops. They're unnaturally large, and he's concerned that Denom might have done something to "improve" the fields which might ultimately prove detrimental to the Ciphers.

Science Boy
Use a Geiger counter on the container of special fertilizer and determine that it's got a moderate amount of radioactive residue in it.

Charisma Boy
If the player is skilled in both deception and persuasion/intimidation (Persuasion/Average, Deception/Average) he will be able to tell that Denom is withholding information about the situation and get a confession out of him.

Stealth Boy
Break into the storage shed by picking the lock (Lockpick/Average) or by stealing the key from Denom (Steal/Average). Discover the empty barrel of fertilizer with the glowing residue. If you know the soil is radioactive, you can confront Denom with this evidence.
