The short answer
1 result is above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 25 health-based violations since 2016.
What handles itWhat was found
Lead and copper: copper at 520 mg/L (2004) 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.
Total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), arsenic, chromium (total) and nitrate: Ohio’s own results, samples taken from Jan. 14, 2020 to Nov. 6, 2025, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit1
Total trihalomethanes (TTHM)
Forms or is added in treatment
107ppb
Highest yearly average, 2020 to 2025
2025 average: 81.4 ppb
Averaged by year, the highest was 107 ppb, in 2020, above EPA’s legal limit of 80 ppb. Its highest single sample was 157 ppb. In 2025, the latest year on file, its eight samples averaged 81.4 ppb, above the limit. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2021, 2022, 2023, 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 62.7 ppb, in 2019.

- Nitrate
What handles it
A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”
- NSF/ANSI 53
Claim: Trihalomethanes (TTHM) Reduction
For: Total trihalomethanes (TTHM)
Other certifiers’ wording: VOC Reduction
- NSF/ANSI 58
Claim: Trihalomethanes (TTHM) Reduction
For: Total trihalomethanes (TTHM)
At the tap, or for the whole house?
These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), arsenic, chromium (total) and nitrate results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Hamler Village’s own annual report, which it must send you every year, has the contaminants this page does not show.
Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.
What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.
Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Ohio’s results run from Jan. 14, 2020 to Nov. 6, 2025.
