The short answer
1 result is above EPA’s legal limit. The worst: Haloacetic acids (HAA5), above the legal limit. 16 health-based violations since 2016.
What was found
Lead and copper: copper at 160 mg/L (2005) is left out of this report: it is one of the results Ohio sent EPA in 2006, all at µg/L magnitudes though EPA’s file marks them mg/L.
Haloacetic acids (HAA5), total trihalomethanes (TTHM) and nitrate: Ohio’s own results, samples taken from Jan. 7, 2020 to Dec. 3, 2025, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit1
Haloacetic acids (HAA5)
Forms or is added in treatment
56.6ppb
Highest yearly average, 2020 to 2025
2025 average: 45.6 ppb
Averaged by year, the highest was 56.6 ppb, in 2021, below EPA’s legal limit of 60 ppb. Its highest single sample was 84.8 ppb. In 2025, the latest year on file, its 10 samples averaged 45.6 ppb. EPA judges this limit at each sampling point, and recorded violations for haloacetic acids (HAA5) at this utility in 2021, 2022 and 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 52.5 ppb, in 2014.
