About this data
A system is counted once if any of its violations in the past three years involved Gross Alpha, Excl. Radon and U, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Gross Alpha, Excl. Radon and U 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.
