The short answer

1 result is above the health goal. The worst: Lead, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2020 to 2025.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.5 ppm, for the period ending June 30, 2009. None since is on file, so it is not counted as a current finding.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride, chromium (total) and arsenic: Ohio’s own results, samples taken from Jan. 23, 2020 to July 17, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

0.5ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 0.5 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Below EPA’s limits

10.6ppb

Highest yearly average, 2020 to 2025

2025: not found

Averaged by year, the highest was 10.6 ppb, in 2022, below EPA’s legal limit of 60 ppb. Its highest single sample was 10.9 ppb. In 2025, the latest year on file, it wasn’t found in any of its two samples.

Highest yearly average, 2020 to 2025

2025 average: 0.25 ppb

Averaged by year, the highest was 11.8 ppb, in 2022, below EPA’s legal limit of 80 ppb. Its highest single sample was 12.4 ppb. In 2025, the latest year on file, its two samples averaged 0.25 ppb.

Nitrate

Below EPA’s limits

1.2ppm

Highest sample; found in 5 of 5

2025, one sample: 0.62 ppm

The highest sample, in 2020, was 1.2 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, its one sample was 0.62 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.8 ppm, in 2017.

0.06ppm

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 0.06 ppm, in 2023, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file.

What handles it

Chromium (total)

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 1.0 ppb, in 2023, below EPA’s legal limit of 100 ppb. That was also the latest year on file.

What handles it

One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic

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.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride, chromium (total) and arsenic results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Odrc - Southeastern Correctional Institute’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. 23, 2020 to July 17, 2025.

Testing your own tap

Odrc - Southeastern Correctional Institute’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Ohio certifies.
