Resources:
Mark discovered that thousands of homes built between 1980-2017 in Western Massachusetts and Northern Connecticut have concrete foundations with pyrrhotite in the aggregate. These foundations will, after a period of 20 years or so, begin to crumble until they are no longer structurally sound.

For more information, check the Connecticut Coalition Against Crumbling Basements (http://www.ccacb.org/).

Additional assistance with this segment was provided by Michelle Loglisci, Russ Dupere, and Mark Violette.
