2,3,7,8-TCDD (Dioxin) violations in Pennsylvania

233 active public water systems in Pennsylvania had a 2,3,7,8-TCDD (Dioxin) violation in the past three years, 13 of them in the latest quarter of EPA's data. What 2,3,7,8-TCDD (Dioxin) is and why it matters.

Health effects: TCDD is classified as a known human carcinogen (Group A) by EPA. Even at extremely low concentrations it is associated with increased cancer risk, particularly soft tissue sarcoma and lymphoma. It also causes chloracne, liver damage, immune suppression, and reproductive and developmental toxicity. The MCL is set at a vanishingly low level reflecting its extreme potency.

About this data

A system is counted once if any of its violations in the past three years involved 2,3,7,8-TCDD (Dioxin), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not 2,3,7,8-TCDD (Dioxin) 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 Pennsylvania 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.
