Dichloromethane (Methylene Chloride) violations in Pennsylvania

173 active public water systems in Pennsylvania had a Dichloromethane (Methylene Chloride) violation in the past three years, 6 of them in the latest quarter of EPA's data. What Dichloromethane (Methylene Chloride) is and why it matters.

Health effects: Chronic exposure to dichloromethane is associated with liver and kidney damage and neurological effects. EPA classifies it as a probable human carcinogen (Group B2); it is metabolized in the body to carbon monoxide and has been linked to cardiovascular stress. Workers in industrial settings and communities near manufacturing sites face the greatest risk.

About this data

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