1,1,2-Trichloroethane violations in North Dakota

1 active public water systems in North Dakota had a 1,1,2-Trichloroethane violation in the past three years, 1 of them in the latest quarter of EPA's data. 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.

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 North Dakota 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.
