The short answer
Nothing in EPA’s and Ohio’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 1 health-based violation since 2016.
What was found
Lead and copper: copper at 122 mg/L (2005) and copper at 106 mg/L (2004) are left out of this report: they are among the results Ohio sent EPA in 2006, all at µg/L magnitudes though EPA’s file marks them mg/L.
Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic and chromium (total): Ohio’s own results, samples taken from Jan. 9, 2020 to Sept. 10, 2025, with EPA’s 2012 to 2019 file for earlier years.

What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Addyston Village PWS’s own annual report, which it must send you every year, has the contaminants this page does not show.
