Atrazine violations in Minnesota

8 active public water systems in Minnesota had a Atrazine violation in the past three years, 2 of them still unresolved. What Atrazine is and why it matters.

Health effects: Chronic exposure to atrazine is associated with endocrine disruption — particularly effects on reproductive hormones — and cardiovascular and adrenal effects in animal studies. EPA classifies atrazine as not likely to be a human carcinogen under current guidelines, though its endocrine-disrupting properties remain under research scrutiny. Fetuses and infants may be most sensitive to hormonal effects.

About this data

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