1,1,2-Trichloroethane violations in Minnesota

7 active public water systems in Minnesota had a 1,1,2-Trichloroethane violation in the past three years, 1 of them still unresolved. What 1,1,2-Trichloroethane is and why it matters.

Health effects: Chronic exposure to 1,1,2-trichloroethane is associated with liver and kidney damage. EPA classifies it as a probable human carcinogen (Group B2) based on animal tumor data. Long-term exposure above the MCL is the primary concern; the general population near contaminated groundwater sources faces the greatest risk.

About this data

A system is counted once if any of its violations in the past three years involved 1,1,2-Trichloroethane, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not 1,1,2-Trichloroethane 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.
