Di(2-ethylhexyl) Phthalate violations in Arizona

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

Health effects: Chronic exposure to DEHP is associated with reproductive and developmental toxicity — it acts as an endocrine disruptor and can interfere with hormone signaling. EPA classifies it as a probable human carcinogen (Group B2) based on animal liver tumor data. Developing fetuses, infants, and reproductive-age adults are most susceptible to its hormonal effects.

About this data

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