Methoxychlor violations in Illinois

59 active public water systems in Illinois had a Methoxychlor violation in the past three years, 12 of them in the latest quarter of EPA's data. What Methoxychlor is and why it matters.

Health effects: Chronic exposure to methoxychlor is associated with reproductive and endocrine disruption — it acts as an estrogen mimic and can interfere with hormone signaling. Liver and kidney effects have been observed in animal studies. Developing fetuses, infants, and individuals with hormonal conditions may be most susceptible.

About this data

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