1,2-Dichloropropane violations in Massachusetts

12 active public water systems in Massachusetts had a 1,2-Dichloropropane violation in the past three years. What 1,2-Dichloropropane is and why it matters.

Health effects: Chronic exposure to 1,2-dichloropropane is associated with liver and kidney damage. EPA classifies it as a probable human carcinogen (Group B2) based on animal evidence of liver and mammary gland tumors. Long-term exposure above the MCL is the primary concern; communities near Superfund sites and former agricultural fumigation areas face elevated exposure risk.

About this data

A system is counted once if any of its violations in the past three years involved 1,2-Dichloropropane, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not 1,2-Dichloropropane 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 Massachusetts 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.
