"A mining dam failure similar to the one that killed more than 100 people in Brazil could happen in the U.S., according to a mine engineer who consults with the government.
At the root of the risk is a quilt of differing state regulations, sloppy dam construction, lax maintenance, neglect of decades-old dams that are wrongly assumed to be stable, and stronger storms dumping water into dams that weren’t designed to handle the weight, said James Kuipers, who consults with the Environmental Protection Agency and state governments on tailings dams, which hold mining waste.
“It can happen here,” Kuipers told Bloomberg Environment."
