The town of Libby in which state became infamous for tremolite asbestos contamination linked to a vermiculite mine?

• A. Washington
• B. Idaho
• C. Minnesota
• D. Montana

Answer: (D)

Libby, Montana is the town famous for tremolite asbestos contamination tied to a vermiculite mine. The vermiculite ore mined near Libby contained tremolite asbestos, and during mining, processing, and sending ore into products like insulation, asbestos fibers spread into the air, soil, and water around the town. People living and working there inhaled these fibers over years, leading to a high incidence of asbestos-related diseases such as asbestosis, mesothelioma, and other cancers. This situation drew national attention and remains one of the most well-known environmental-health disasters linked to asbestos in the United States, with federal cleanup efforts focused on Libby.
