Combined Uranium violations in Nebraska

5 active public water systems in Nebraska had a Combined Uranium violation in the past three years, 1 of them in the latest quarter of EPA's data. What Combined Uranium is and why it matters.

Health effects: Uranium poses both radiological and chemical health risks. Chronic exposure is primarily associated with kidney damage due to its chemical toxicity as a heavy metal. The radiological risk — increased cancer probability — is also present but secondary to the nephrotoxic concern at drinking water concentrations. There is no safe threshold for radiation exposure.

About this data

A system is counted once if any of its violations in the past three years involved Combined Uranium, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Combined Uranium alone.

The Nebraska 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.
