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 118 mg/L (2005) and copper at 164 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.
Haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and total trihalomethanes (TTHM): Ohio’s own results, samples taken from July 14, 2020 to July 7, 2025, with EPA’s 2012 to 2019 file for earlier years.
