This project will provide information about the fate of mercury in synthetic gypsum produced by wet FGD systems on coal-fired power plants, when used as feedstock for wallboard production. Wet FGD systems play a key role in current and future efforts to limit the air emissions of mercury control from coal-fired plants.
