Trichloroethylene (TCE) violations in Oregon

87 active public water systems in Oregon had a Trichloroethylene (TCE) violation in the past three years, 3 of them in the latest quarter of EPA's data. What Trichloroethylene (TCE) is and why it matters.

Health effects: TCE is classified by EPA as a known human carcinogen (Group A), associated primarily with kidney cancer and non-Hodgkin lymphoma. It is also linked to liver cancer and cervical cancer. Prenatal exposure is associated with cardiac defects. Workers at industrial facilities and residents near contaminated groundwater plumes face the greatest risk.

About this data

A system is counted once if any of its violations in the past three years involved Trichloroethylene (TCE), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Trichloroethylene (TCE) 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 Oregon 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.
