1 active public water systems in North Dakota had a 1,2-Dichloroethane violation in the past three years, 1 of them still unresolved. What 1,2-Dichloroethane is and why it matters.

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