The Porgera Gold Mine, run by Barrick Gold, is a mine near Strickland, which is the source of environmental concerns in the area. Since 1992, Barrick Gold has dumped mine waste, particularly metal particulates or tailings, directly into the river. This process of riverine disposal by the mine has led to much controversy, with numerous deaths and environmental problems being blamed on the metal particulates.
