Benzo(a)pyrene violations in North Carolina

13 active public water systems in North Carolina had a Benzo(a)pyrene violation in the past three years, 1 of them in the latest quarter of EPA's data. What Benzo(a)pyrene is and why it matters.

Health effects: Benzo(a)pyrene is classified by EPA as a probable human carcinogen (Group B2) and is a well-established animal carcinogen. Long-term exposure is associated with increased cancer risk, particularly for reproductive organ cancers. It is also linked to immune system effects and developmental toxicity in animal studies.

About this data

A system is counted once if any of its violations in the past three years involved Benzo(a)pyrene, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Benzo(a)pyrene 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 North Carolina 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.
