1,2-Dibromo-3-Chloropropane (DBCP) violations in Minnesota

5 active public water systems in Minnesota had a 1,2-Dibromo-3-Chloropropane (DBCP) violation in the past three years, 2 of them in the latest quarter of EPA's data. What 1,2-Dibromo-3-Chloropropane (DBCP) is and why it matters.

Health effects: DBCP is classified by EPA as a probable human carcinogen (Group B2). It causes male reproductive toxicity — including reduced sperm count and sterility — at relatively low exposure levels. Chronic exposure is also associated with kidney damage. Men of reproductive age and developing fetuses are most at risk.

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 Minnesota 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.
