A major environmental cleanup has been completed at Gruber's Grove Bay, a residential and recreational area of the Wisconsin River located near Badger Army Ammunition Plant (AAP) in Wisconsin. During the cleanup, about 90,000 cu. yds. of sediment were dredged from the bottom of the 25-acre bay. The sediments, deposited prior to 1972 by production at Badger AAP, had shown elevated levels of mercury, lead and copper. Dredging took place during spring, summer and fall 2001. Gruber's Grove Bay was closed throughout the cleanup, an action that demonstrated the strength of the partnership that made the cleanup possible. The partnership consisted of the Army, the Wisconsin Department of Natural Resources, the U.S.
