MacDonnell is employed with removing the taint of Scourge upon the Plaguelands; and with the help of an alchemist named Arbington, she meets with a limited amount of success. She discovered that Kel'Thuzad is maintaining the Scourge with massive plague cauldrons placed on each of the farms in the Plaguelands. These cauldrons emit a diseased cloud that contaminates the land; fortunately MacDonnell and Arbington believe this effect can be reversed with an experimental potion, but they haven't had the manpower to try it yet.APG 151DF 126
