The short answer

1 result is above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 26 health-based violations since 2016.

What handles it

What was found

Lead and copper: copper at 9.5 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.

Total trihalomethanes (TTHM) and haloacetic acids (HAA5): Ohio’s own results, samples taken from Jan. 9, 2020 to Oct. 9, 2025, with EPA’s 2012 to 2019 file for earlier years.

133ppb

Highest yearly average, 2020 to 2025

2025 average: 46.3 ppb

Averaged by year, the highest was 133 ppb, in 2021, above EPA’s legal limit of 80 ppb. Its highest single sample was 159 ppb. In 2025, the latest year on file, its four samples averaged 46.3 ppb. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2020, 2021 and 2022. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 139 ppb, in 2019, and EPA recorded violations in 2014, 2015, 2016, 2017, 2018 and 2019.

  • 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: 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) and haloacetic acids (HAA5) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Brunersburg WD - Evansport PWS’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. 9, 2020 to Oct. 9, 2025.

Testing your own tap

Brunersburg WD - Evansport PWS’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.
