Help! Broken Steel Project Purity water irradiated.

[tsxylis]

You know at the end of the quest Take it Back! right? How after that the water in the Project Purity water turns all nice and clean? Well part of that nice clean water has turned nasty and irradiated again. The contrast is easily seen and it ticks me the hell off. Its the area where the BOS guy flames the mirelurks-I would take a screenie but i have no idea how to :(. Is there anyway of fixing this? I'm using the PC version of FO3 and I have all 5 DLCs and bucketload of mods, waaay too many to list all of them. Some of the main ones are-

Unofficial Fallout 3 Patch(+all the DLC versions)

Cube Experimental (EN)

Enclave Commander

CALIBR

Enhanced Weather-Rain and Snow

Weapon Mod Kits

MMM-Increased Increased Spawns

MMM-Zones Respawn

Fellout(all DLC versions too)

Darkness

Malos Arena (EV)

 

Cheers for any help.
