Libby Asbestos

What's New?

After rigorous scientific review, EPA has completed the final toxicological review of Libby Amphibole asbestos (LA). This includes the potential cancer and non-cancer human health effects from inhalation exposure to LA. Using these values and exposure data collected in Libby and Troy, EPA has also completed a draft Site-wide Human Health Risk Assessment.

Are You New to Libby?

Libby Asbestos site location map

Since November 1999, EPA has cleaned up the major source areas of contamination around town. EPA is now cleaning up smaller sources found in a variety of places such as around homes and businesses. EPA conducts stringent clearance sampling after cleanup and has begun some targeted sampling to measure the effectiveness of cleanup several months later. EPA is also working on long-term plans to ensure that the cleanup remains protective and human health risks continue to be reduced over time. EPA's ongoing cleanup efforts continue to make Libby a safer place to live, work, and visit.

Until the cleanup is finished, disturbance of vermiculite is the most likely source of exposures to asbestos. So, learn what it looks like and where it is likely to be found—then leave it alone!
