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. No health-based violations on file since 2016.
What was found
Lead and copper: copper at 125 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), nitrate, arsenic, chromium (total), fluoride and haloacetic acids (HAA5): Ohio’s own results, samples taken from Jan. 6, 2020 to Oct. 8, 2025, with EPA’s 2012 to 2019 file for earlier years.

Total trihalomethanes (TTHM)
Forms or is added in treatment
4.3ppb
Highest yearly average, 2020 to 2025
2025, one sample: 3.4 ppb
Averaged by year, the highest was 4.3 ppb, in 2023, below EPA’s legal limit of 80 ppb. Its highest single sample was 4.3 ppb. In 2025, the latest year on file, its one sample was 3.4 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.2 ppb, in 2017.

2025: not found
The highest sample, in 2022, was 0.09 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.14 ppm, in 2018.

- Arsenic
- Chromium (total)
- Fluoride
- Haloacetic acids (HAA5)
- Lead
Hardness
Very hard, 338 mg/L (19.8 grains per gallon), at its one sampling point, in 2021.
Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.
Violations since 2016
No health-based violations on file with EPA since 2016. There are 3 monitoring or reporting violations: a sample missed, late or not reported.
What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), nitrate, arsenic, chromium (total), fluoride and haloacetic acids (HAA5) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Towbridge Development’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. 6, 2020 to Oct. 8, 2025.
