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 610 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.

Arsenic, haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride and chromium (total): Ohio’s own results, samples taken from Sept. 8, 2020 to Oct. 14, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

3.4ppb

Highest yearly average, 2021 to 2024

2024: not found

Averaged by year, the highest was 3.4 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2024, 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

7.1ppb

Highest yearly average, 2020 to 2025

Averaged by year, the highest was 7.1 ppb, in 2025, below EPA’s legal limit of 60 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 6.1 ppb, in 2015.

What handles it

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

5.4ppb

Highest yearly average, 2020 to 2025

Averaged by year, the highest was 5.4 ppb, in 2025, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.0 ppb, in 2015.

What handles it

  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Nitrate

Comes from the source

Below EPA’s limits

0.62ppm

Highest sample; found in 5 of 6

2025, one sample: 0.37 ppm

The highest sample, in 2021, was 0.62 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, its one sample was 0.37 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.4 ppm, in 2018.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.12ppm

Highest yearly average, 2021 to 2024

2024: not found

Averaged by year, the highest was 0.12 ppm, in 2021, below EPA’s legal limit of 4.0 ppm. In 2024, 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 0.15 ppm, in 2015.

What handles it

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.

What this report can’t tell you

  • Everything else. Arsenic, haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Brunswick Hills MHP’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 Sept. 8, 2020 to Oct. 14, 2025.

Testing your own tap

Brunswick Hills MHP’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.
