Hexachlorocyclopentadiene violations in New Jersey

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

Health effects: Chronic exposure to hexachlorocyclopentadiene is associated with kidney and stomach damage in animal studies. EPA has not classified it as a human carcinogen based on available data. Short-term high-level exposure may cause irritation of mucous membranes. Long-term exposure 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 Hexachlorocyclopentadiene, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Hexachlorocyclopentadiene 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 New Jersey 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.
