Picloram violations in Minnesota

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

Health effects: Chronic exposure to picloram is associated with liver damage in animal studies. EPA classifies it as a possible human carcinogen (Group C). The general population faces chronic risk from prolonged exposure above the MCL, particularly in agricultural regions where it is applied to rangeland and rights-of-way.

About this data

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