The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2019 to 2026.

Arsenic, nitrate, chromium (total) and fluoride: Utah’s own results, samples taken from Oct. 18, 2022 to Oct. 27, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

3.3ppb

Highest yearly average, 2022 to 2025

2025, one sample: 3.2 ppb

Averaged by year, the highest was 3.3 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, its one sample was 3.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.8 ppb, in 2019.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Lead

Comes from pipes, often your own

Above the health goal

3.7ppb

90th percentile, 2024 to 2026

In the latest period, 9 in 10 homes sampled were at or below 3.7 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 limits2

Nitrate

Comes from the source

Below EPA’s limits

0.89ppm

One sample

2025, one sample: 0.89 ppm

The highest sample, in 2025, was 0.89 ppm, below EPA’s legal limit of 10 ppm. That is the only year on file, and its one sample was 0.89 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.7 ppm, in 2019.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Chromium (total)

Comes from the source

Below EPA’s limits

4.2ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 4.2 ppb, in 2025, below EPA’s legal limit of 100 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.3 ppb, in 2019.

What handles it

One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Fluoride

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

    For: Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Arsenic, Lead

    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, nitrate, chromium (total) and fluoride results here are Utah’s own from 2022 on, with EPA’s national file for 2012 to 2019. Harmony Mtn Ranches’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; Utah’s results run from Oct. 18, 2022 to Oct. 27, 2025.

Testing your own tap

Harmony Mtn Ranches’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.
