The short answer

2 results are 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 2018 to 2025. Copper at 162 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.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.6 ppm, for the period ending Dec. 31, 1993. None since is on file, so it is not counted as a current finding.

Arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate and chromium (total): Ohio’s own results, samples taken from May 20, 2020 to Aug. 14, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

2.1ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 2.1 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.

What handles it

Arsenic

Comes from the source

Above the health goal

0.9ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 0.9 ppb, in 2023: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That was also the latest year on file.

What handles it

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

Below EPA’s limits4

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

46.8ppb

Highest yearly average, 2020 to 2025

2025 average: 32.1 ppb

Averaged by year, the highest was 46.8 ppb, in 2024, below EPA’s legal limit of 80 ppb. Its highest single sample was 48.8 ppb. In 2025, the latest year on file, its two samples averaged 32.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 64.6 ppb, in 2014.

Fluoride

Below EPA’s limits

2.0ppm

Highest yearly average, 2020 to 2023

2023, one sample: 1.7 ppm

Averaged by year, the highest was 2.0 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. In 2023, the latest year on file, its one sample was 1.7 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.7 ppm, in 2014.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

13.7ppb

Highest yearly average, 2020 to 2025

2025 average: 8.3 ppb

Averaged by year, the highest was 13.7 ppb, in 2023, below EPA’s legal limit of 60 ppb. Its highest single sample was 15.5 ppb. In 2025, the latest year on file, its two samples averaged 8.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.0 ppb, in 2012.

Nitrate

Comes from the source

Below EPA’s limits

0.36ppm

Highest sample; found in 4 of 6

2025: not found

The highest sample, in 2023, was 0.36 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 0.95 ppm, in 2012.

What handles it

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

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

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

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

  • NSF/ANSI 58

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

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

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. Arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Baltimore Village 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 May 20, 2020 to Aug. 14, 2025.

Testing your own tap

Baltimore Village 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.
