Coverage zones:
- Connecticut — confirmed hot spots with case counts
- Massachusetts — confirmed, no public count available
- Rhode Island & New Hampshire — watch zones
Data note: Connecticut case counts are from the CRCOG crumbling foundations data set. Massachusetts has confirmed cases but no centralized public count. Rhode Island and New Hampshire are designated watch zones due to shared geological formations; as of this writing, neither state has confirmed residential pyrrhotite hot spots. All data is subject to change. Verify critical information with your state's geological survey or CRCOG.
