Cleanup of East Helena smelter site in full swing

From atop the black mass of the East Helena slag pile, Environmental Protection Agency project manager Betsy Burns pointed to the features of an engineered floodplain and creek channel where Prickly Pear Creek will one day flow.

Heavy machinery revved and chirped below -- to the east digging the channel, and to the west constructing a cap of rock and topsoil over contaminated material below the surface.
