Simazine violations in Illinois

68 active public water systems in Illinois had a Simazine violation in the past three years, 10 of them in the latest quarter of EPA's data. What Simazine is and why it matters.

Health effects: Chronic exposure to simazine is associated with potential cancer risk; EPA classifies it as a possible human carcinogen (Group C) based on animal studies. Blood and nervous system effects have also been observed in animal studies. Long-term exposure at levels above the MCL is the primary concern for public water system violations.

About this data

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