Pentachlorophenol violations in New York
119 active public water systems in New York had a Pentachlorophenol violation in the past three years, 1 of them in the latest quarter of EPA's data. What Pentachlorophenol is and why it matters.
Health effects: Chronic exposure to pentachlorophenol is associated with liver and kidney damage and immune system effects. EPA classifies it as a probable human carcinogen (Group B2). Acute high-level exposure can cause fever, profuse sweating, and cardiovascular collapse. Workers and communities near wood treatment facilities face the greatest exposure risk.

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