In the small town of Libby, Montana, more than a thousand people have been diagnosed with lung disease and over 200 have died from exposure to vermiculite, a type of asbestos used for insulation in homes. The contaminated town became a Superfund site and executives from W.R. Grace, the company that owned the vermiculite mine, will soon go to trial on charges they covered up the extent of asbestos contamination in Libby and obstructed regulators from investigating. Host Steve Curwood talks with Drury Gunn Carr who co-directed a documentary on Libby, Montana, which will soon air on PBS’ POV series.
