The short answer

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

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2002 to 2025.

Nitrate, arsenic, fluoride and chromium (total): Utah’s own results, samples taken from Jan. 3, 2020 to Aug. 18, 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 Sept. 25, 2012 to July 31, 2017. Newer results are in the utility’s annual water quality report.

Above the health goal3

Nitrate

Comes from the source

Above the health goal

15.9ppm

Highest sample; found in 72 of 73

2026 average: 5.9 ppm

From 2022 to 2023, four samples were above EPA’s legal limit of 10 ppm, the highest 15.9 ppm in 2023. The next sample at the same point, within 30 days, kept the average above the limit for two; one came back under and one has no follow-up sample on file within 30 days. 10 ppm is also EPA’s health goal. In 2026, the latest year on file, its eight samples averaged 5.9 ppm. EPA recorded no violation for nitrate at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 9.7 ppm, in 2018.

What handles it

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

Arsenic

Comes from the source

Above the health goal

9.4ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 9.4 ppb, in 2026: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 17.1 ppb. That was also the latest year on file. EPA recorded no violation for arsenic at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 10.8 ppb, in 2012, and EPA recorded a violation in 2012. One result, 3,650 ppb on Jan. 3, 2020 in Utah’s results, is left out as a likely entry error: the typical result there is 7.1 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

3.5ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 3.5 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

Below EPA’s limits2

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

32.4ppb

Highest yearly average, 2012 to 2017

2017, one sample: 7.6 ppb

Averaged by year, the highest was 32.4 ppb, in 2014, below EPA’s legal limit of 80 ppb. In 2017, the latest year on file, its one sample was 7.6 ppb.

What handles it

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

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.29ppm

Highest yearly average, 2023

Averaged by year, the highest was 0.29 ppm, in 2023, below EPA’s legal limit of 4.0 ppm. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.4 ppm, in 2014.

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: Nitrate/Nitrite (30 ppm challenge), Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Nitrate, Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Nitrate, Arsenic, Lead

    Other certifiers’ wording: Nitrate; 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. Nitrate, arsenic, 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. Central Culinary Water Co’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 Jan. 3, 2020 to Aug. 18, 2026; EPA’s compliance samples are from Sept. 25, 2012 to July 31, 2017.

Testing your own tap

Central Culinary Water Co’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.
