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

Arsenic, haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, chromium (total) and nitrate: Kansas’s own results, samples taken from Jan. 6, 2020 to July 6, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

1.4ppb

Highest yearly average, 2022 to 2025

2025: not found

Averaged by year, the highest was 1.4 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. 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 yearly average of 1.9 ppb, in 2013.

Below EPA’s limits3

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

35.3ppb

Highest yearly average, 2020 to 2026

2026 average: 21.7 ppb

Averaged by year, the highest was 35.3 ppb, in 2020, below EPA’s legal limit of 60 ppb. Its highest single sample was 56 ppb. In 2026, the latest year on file, its three samples averaged 21.7 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 31 ppb, in 2015.

Total trihalomethanes (TTHM)

Below EPA’s limits

44.7ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 44.7 ppb, in 2026, below EPA’s legal limit of 80 ppb. Its highest single sample was 90 ppb. That was also the latest year on file. EPA recorded no violation for total trihalomethanes (TTHM) at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 38 ppb, in 2015.

Fluoride

Below EPA’s limits

0.72ppm

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 0.72 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 0.48 ppm, in 2013.

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, 190 mg/L (11.1 grains per gallon), at its one sampling point, 2016 to 2025.

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

What this report can’t tell you

  • Everything else. Arsenic, haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, chromium (total) and nitrate results here are Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Arma’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; Kansas’s results run from Jan. 6, 2020 to July 6, 2026.

Testing your own tap

City of Arma’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 Kansas certifies.

The lab Kansas certifies closest to the area City of Arma serves, in a straight line. Call first: certification is test by test, and not every lab takes samples from homeowners.
