Heptachlor Epoxide violations in Pennsylvania

201 active public water systems in Pennsylvania had a Heptachlor Epoxide violation in the past three years, 8 of them in the latest quarter of EPA's data. What Heptachlor Epoxide is and why it matters.

Health effects: Heptachlor epoxide is associated with liver damage and is classified by EPA as a probable human carcinogen (Group B2). It bioaccumulates in fatty tissue and can be transferred to infants through breast milk. Chronic low-level exposure is the primary concern in drinking water contexts.

About this data

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