o-Dichlorobenzene violations in Michigan

165 active public water systems in Michigan had a o-Dichlorobenzene violation in the past three years, 4 of them in the latest quarter of EPA's data. What o-Dichlorobenzene is and why it matters.

Health effects: Chronic exposure to o-dichlorobenzene is associated with liver, kidney, and blood effects in animal studies. EPA has not classified it as a human carcinogen based on current data. Long-term exposure above the MCL is the primary concern; the general population is at risk from contaminated groundwater sources.

About this data

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