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 2009 to 2024.

Arsenic, nitrate, fluoride and chromium (total): Utah’s own results, samples taken from July 17, 2020 to Nov. 18, 2025, with EPA’s 2012 to 2019 file for earlier years.

Total trihalomethanes (TTHM) and haloacetic acids (HAA5): EPA’s compliance monitoring file, samples taken from Sept. 5, 2012 to July 11, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

2.0ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 2.0 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

0.8ppb

Highest yearly average, 2022 to 2025

2025 average: 0.5 ppb

Averaged by year, the highest was 0.8 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 1.0 ppb. In 2025, the latest year on file, its two samples averaged 0.5 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.7 ppb, in 2019.

8.1ppb

Highest yearly average, 2012 to 2019

Averaged by year, the highest was 8.1 ppb, in 2019, below EPA’s legal limit of 80 ppb. That was also the latest year on file.

Nitrate

Comes from the source

Below EPA’s limits

0.55ppm

Highest sample; found in 6 of 6

2025 average: 0.42 ppm

The highest sample, in 2025, was 0.55 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its two samples averaged 0.42 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.7 ppm, in 2014.

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.15ppm

Highest yearly average, 2022 to 2025

2025: not found

Averaged by year, the highest was 0.15 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. In 2025, the latest year on file, it wasn’t found in any of its two samples. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.2 ppm, in 2012.

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.

Hardness

Very hard, 211 mg/L (12.3 grains per gallon), at its one sampling point, in 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 6 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Arsenic, nitrate, fluoride and chromium (total) results here are Utah’s own from 2020 on, with EPA’s national file for 2012 to 2019. Total trihalomethanes (TTHM) and haloacetic acids (HAA5) come from EPA’s file alone, which ends in 2019. Kamas City Water System’s own annual report, which it must send you every year, has newer results for those and 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; Utah’s results run from July 17, 2020 to Nov. 18, 2025; EPA’s compliance samples are from Sept. 5, 2012 to July 11, 2019.

Testing your own tap

Kamas City Water System’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 Utah certifies.
