Endrin violations in Wisconsin

18 active public water systems in Wisconsin had a Endrin violation in the past three years. What Endrin is and why it matters.

Health effects: Endrin is acutely toxic to the nervous system and can cause seizures, headache, dizziness, and liver damage at high doses. Chronic low-level exposure is associated with liver and nervous system effects. EPA classifies it as a possible human carcinogen (Group C). Children and the elderly are most vulnerable to acute neurological effects.

About this data

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