Ethylbenzene violations in Pennsylvania

171 active public water systems in Pennsylvania had a Ethylbenzene violation in the past three years, 6 of them in the latest quarter of EPA's data. What Ethylbenzene is and why it matters.

Health effects: Chronic exposure to ethylbenzene is associated with liver and kidney effects. EPA classifies it as a possible human carcinogen (Group D — inadequate evidence) based on limited animal data. Short-term high-level exposure can cause eye and throat irritation and dizziness. 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 Ethylbenzene, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Ethylbenzene 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.
