The short answer

2 results are 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

Lead and copper: EPA SDWIS monitoring periods ending 2005 to 2025.

Arsenic, nitrate, fluoride and chromium (total): Utah’s own results, samples taken from Sept. 3, 2020 to July 28, 2026, 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 Aug. 12, 2014 to Aug. 12, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

5.2ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 5.2 ppb, in 2025: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.7 ppb, in 2016.

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

1.8ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 1.8 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 limits4

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

29.6ppb

Highest yearly average, 2014 to 2019

2019, one sample: 15.4 ppb

Averaged by year, the highest was 29.6 ppb, in 2017, below EPA’s legal limit of 80 ppb. In 2019, the latest year on file, its one sample was 15.4 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

1.7ppm

Highest sample; found in 6 of 7

2026, one sample: 0.28 ppm

The highest sample, in 2022, was 1.7 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 0.28 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.7 ppm, in 2017.

What handles it

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

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

7.2ppb

Highest yearly average, 2014 to 2019

2019: not found

Averaged by year, the highest was 7.2 ppb, in 2017, below EPA’s legal limit of 60 ppb. In 2019, the latest year on file, it wasn’t found in its one sample.

What handles it

No certification claim covers this compound yet.

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.44ppm

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 0.44 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 0.7 ppm, in 2016.

What handles it

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: 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, 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. Minersville 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 Sept. 3, 2020 to July 28, 2026; EPA’s compliance samples are from Aug. 12, 2014 to Aug. 12, 2019.

Testing your own tap

Minersville 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.
