The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Copper, above the action level. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1997 to 2024.

Arsenic, nitrate, fluoride and chromium (total): Utah’s own results, samples taken from April 10, 2020 to Aug. 18, 2026, with EPA’s 2012 to 2019 file for earlier years.

Haloacetic acids (HAA5) and total trihalomethanes (TTHM): EPA’s compliance monitoring file, samples taken from Aug. 6, 2012 to July 29, 2019. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Copper

Comes from pipes, often your own

Above the action level

1.6ppm

90th percentile, 2024

In the latest period, 9 in 10 homes sampled were at or below 1.6 ppm, above EPA’s action level of 1.3 ppm.

What handles it

Above the health goal2

Arsenic

Comes from the source

Above the health goal

1.2ppb

Highest yearly average, 2020 to 2026

2026, one sample: 1.0 ppb

Averaged by year, the highest was 1.2 ppb, in 2020: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2026, the latest year on file, its one sample was 1.0 ppb.

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

1.5ppb

90th percentile, 2026

In the latest period, 9 in 10 homes sampled were at or below 1.5 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

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

13.3ppb

Highest yearly average, 2012 to 2019

2019, one sample: 6.7 ppb

Averaged by year, the highest was 13.3 ppb, in 2017, below EPA’s legal limit of 60 ppb. In 2019, the latest year on file, its one sample was 6.7 ppb.

16.1ppb

Highest yearly average, 2012 to 2019

2019, one sample: 15.3 ppb

Averaged by year, the highest was 16.1 ppb, in 2014, below EPA’s legal limit of 80 ppb. In 2019, the latest year on file, its one sample was 15.3 ppb.

What handles it

  • NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Nitrate

Comes from the source

Below EPA’s limits

1.6ppm

Highest sample; found in 13 of 13

2026 average: 1.0 ppm

The highest sample, in 2020, was 1.6 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its three samples averaged 1.0 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)”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.19ppm

Highest yearly average, 2020 to 2026

2026, one sample: 0.11 ppm

Averaged by year, the highest was 0.19 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. In 2026, the latest year on file, its one sample was 0.11 ppm.

What handles it

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

    For: Copper, Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Copper, 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.

Hardness

Soft to very hard depending on the source, 18 to 265 mg/L (1.1 to 15.5 grains per gallon), across 2 sampling points, 2021 to 2026.

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.

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. Haloacetic acids (HAA5) and total trihalomethanes (TTHM) come from EPA’s file alone, which ends in 2019. Highlands Water Company Inc’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 April 10, 2020 to Aug. 18, 2026; EPA’s compliance samples are from Aug. 6, 2012 to July 29, 2019.

Testing your own tap

Highlands Water Company Inc’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.
