Diquat violations in Indiana

27 active public water systems in Indiana had a Diquat violation in the past three years, 2 of them in the latest quarter of EPA's data. What Diquat is and why it matters.

Health effects: Chronic exposure to diquat is associated with cataracts and kidney damage in animal studies. Acute high-level exposure causes gastrointestinal distress. EPA has not classified diquat as a human carcinogen. Individuals with kidney conditions may be at elevated risk from chronic exposure.

About this data

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