Di(2-ethylhexyl) Adipate violations in North Carolina

11 active public water systems in North Carolina had a Di(2-ethylhexyl) Adipate violation in the past three years, 1 of them in the latest quarter of EPA's data. What Di(2-ethylhexyl) Adipate is and why it matters.

Health effects: Chronic exposure to DEHA is associated with reproductive effects and decreased body weight in animal studies. EPA classifies it as a possible human carcinogen (Group C). Long-term exposure above the MCL is the primary concern; the general population is at risk, with potential for greater sensitivity in developing fetuses and reproductive-age adults.

About this data

A system is counted once if any of its violations in the past three years involved Di(2-ethylhexyl) Adipate, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Di(2-ethylhexyl) Adipate 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 North Carolina 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.
