The short answer

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

What handles it

What was found

Lead and copper: copper at 59.5 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.

Arsenic, haloacetic acids (HAA5), fluoride, total trihalomethanes (TTHM), nitrate and chromium (total): Ohio’s own results, samples taken from Feb. 18, 2020 to July 14, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Arsenic

Above the health goal

1.8ppb

Highest yearly average, 2020 to 2023

2023: not found

Averaged by year, the highest was 1.8 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2023, the latest year on file, it wasn’t found in its one sample.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Below EPA’s limits4

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

15.1ppb

Highest yearly average, 2020 to 2025

2025, one sample: 3.3 ppb

Averaged by year, the highest was 15.1 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2025, the latest year on file, its one sample was 3.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 33.6 ppb, in 2019.

Highest yearly average, 2020 to 2023

2023: not found

Averaged by year, the highest was 0.61 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.66 ppm. In 2023, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.31 ppm, in 2014.

What handles it

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

9.1ppb

Highest yearly average, 2020 to 2025

2025, one sample: 3.2 ppb

Averaged by year, the highest was 9.1 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2025, the latest year on file, its one sample was 3.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 53 ppb, in 2017.

Nitrate

Comes from the source

Below EPA’s limits

0.27ppm

Highest sample; found in 2 of 8

2025: not found

The highest sample, in 2021, was 0.27 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 0.7 ppm, in 2019.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Chromium (total)
  • Lead

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: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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.

Hardness

Very hard, 377 mg/L (22 grains per gallon), at its one sampling point, in 2022.

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 4 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Arsenic, haloacetic acids (HAA5), fluoride, total trihalomethanes (TTHM), nitrate and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Deer Run Mc’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 Feb. 18, 2020 to July 14, 2025.

Testing your own tap

Deer Run Mc’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.
