Benzene violations in Minnesota

7 active public water systems in Minnesota had a Benzene violation in the past three years, 1 of them in the latest quarter of EPA's data. What Benzene is and why it matters.

Health effects: Benzene is classified by EPA as a known human carcinogen (Group A). Long-term exposure causes leukemia, particularly acute myeloid leukemia (AML), and other blood disorders including aplastic anemia. There is no established safe threshold. Children and individuals with compromised immune systems are most vulnerable to hematological effects.

About this data

A system is counted once if any of its violations in the past three years involved Benzene, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Benzene alone.

Source: the U.S. EPA's Enforcement and Compliance History Online system (ECHO), which publishes the federal Safe Drinking Water Information System. EPA's terms and values are shown as published. 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.
