Libby, Montana


Episode Info

"Libby, Montana" examines the impact of 70 years of mining the mineral vermiculite on the town, where about a quarter of the population was found to have lung abnormalities from asbestos exposure. The documentary also details claims that W.R. Grace & Co., which owned the mine, concealed the dangers faced by workers, even as the company and a number of executives faced criminal charges; and questions why the government permitted the mine to operate until its 1990 closure.
