Gross Alpha, Excl. Radon and U violations in Pennsylvania

175 active public water systems in Pennsylvania had a Gross Alpha, Excl. Radon and U violation in the past three years, 5 of them in the latest quarter of EPA's data. What Gross Alpha, Excl. Radon and U is and why it matters.

Health effects: Alpha-emitting radionuclides accumulate in bone and soft tissue, delivering sustained internal radiation doses that increase lifetime cancer risk. There is no established safe threshold for ionizing radiation. Individual contributors such as radium-226 and polonium-210 have their own MCLs; gross alpha serves as a cost-effective screening tool that triggers more specific radionuclide analysis when exceeded.

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 Pennsylvania 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.
