About this data
A system is counted once if any of its violations in the past three years involved Combined Radium (-226 and -228), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Combined Radium (-226 and -228) alone.

The Michigan records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
