Di(2-ethylhexyl) Adipate violations in Rhode Island

9 active public water systems in Rhode Island had a Di(2-ethylhexyl) Adipate violation in the past three years. 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.

The Rhode Island 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.
