National Asbestos Exposure Review (NAER) tracks Libby vermiculite sites

National Asbestos Exposure Review (NAER): Vermiculite was mined and processed in Libby, Montana, from the early 1920s until 1990. We now know that this vermiculite, which was shipped to many locations around the U.S. for processing, contained asbestos.
