The short answer

3 results are above the health goal. The worst: Nitrate, 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 702 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.

Nitrate, arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5) and chromium (total): Ohio’s own results, samples taken from Jan. 14, 2020 to Oct. 16, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal3

Nitrate

Comes from the source

Above the health goal

13ppm

Highest sample; found in 18 of 19

2025 average: 0.73 ppm

One sample, in 2021, was above EPA’s legal limit of 10 ppm, at 13 ppm. The next sample at the same point, within 30 days, brought the average back under the limit. 10 ppm is also EPA’s health goal. In 2025, the latest year on file, its two samples averaged 0.73 ppm. EPA recorded no violation for nitrate at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.22 ppm, in 2015.

Arsenic

Comes from the source

Above the health goal

5.9ppb

Highest yearly average, 2020 to 2025

2025 average: 5.2 ppb

Averaged by year, the highest was 5.9 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 11 ppb. In 2025, the latest year on file, its five samples averaged 5.2 ppb. EPA recorded no violation for arsenic at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 7.5 ppb, in 2014.

Lead

Comes from pipes, often your own

Above the health goal

1.4ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 1.4 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

Below EPA’s limits3

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

52.2ppb

Highest yearly average, 2020 to 2025

2025, one sample: 24.8 ppb

Averaged by year, the highest was 52.2 ppb, in 2023, below EPA’s legal limit of 80 ppb. In 2025, the latest year on file, its one sample was 24.8 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 22 ppb, in 2016.

Fluoride

Forms or is added in treatment

Below EPA’s limits

1.5ppm

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 1.5 ppm, in 2025, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.5 ppm, in 2019.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

10.9ppb

Highest yearly average, 2020 to 2025

2025, one sample: 6.7 ppb

Averaged by year, the highest was 10.9 ppb, in 2023, below EPA’s legal limit of 60 ppb. In 2025, the latest year on file, its one sample was 6.7 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 12.2 ppb, in 2017.

What handles it

No certification claim covers this compound yet.

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: Nitrate/Nitrite (30 ppm challenge), Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Nitrate, Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Nitrate, Arsenic, Lead

    Other certifiers’ wording: Nitrate; 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. Nitrate, arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5) and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Village of West Manchester’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. 14, 2020 to Oct. 16, 2025.

Testing your own tap

Village of West Manchester’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.
