1,2-Dichloropropane violations in Minnesota

7 active public water systems in Minnesota had a 1,2-Dichloropropane violation in the past three years, 1 of them still unresolved. 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.
