About this data
A system is counted once if any of its violations in the past three years involved 1,2-Dibromo-3-Chloropropane (DBCP), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not 1,2-Dibromo-3-Chloropropane (DBCP) alone.

The Montana 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.
