The short answer
1 result is above the health goal. The worst: Arsenic, above the health goal. 2 health-based violations since 2016.
What handles itWhat was found
Nitrate: Utah’s own results, samples taken from Aug. 24, 2020 to Feb. 20, 2026, with EPA’s 2012 to 2019 file for earlier years.
Arsenic, fluoride, total trihalomethanes (TTHM), chromium (total) and haloacetic acids (HAA5): EPA’s compliance monitoring file, samples taken from Aug. 11, 2014 to June 10, 2019. Newer results are in the utility’s annual water quality report.
Above the health goal1
Arsenic
Comes from the source
0.75ppb
Highest yearly average, 2019
Averaged by year, the highest was 0.75 ppb, in 2019: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 0.9 ppb. That is the only year on file.
What handles it
- NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
- NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
Below EPA’s limits3
Nitrate
Comes from the source
2.5ppm
Highest sample; found in 14 of 14
2026 average: 1.9 ppm
The highest sample, in 2022, was 2.5 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its two samples averaged 1.9 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 2.6 ppm, in 2016.

Fluoride
Forms or is added in treatment
0.22ppm
Highest yearly average, 2019
Averaged by year, the highest was 0.22 ppm, in 2019, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.29 ppm. That is the only year on file.

Total trihalomethanes (TTHM)
Forms or is added in treatment
1.6ppb
Highest yearly average, 2014 to 2017
2017, one sample: 1.1 ppb
Averaged by year, the highest was 1.6 ppb, in 2014, below EPA’s legal limit of 80 ppb. Its highest single sample was 1.6 ppb. In 2017, the latest year on file, its one sample was 1.1 ppb.

3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
- Chromium (total)
- Haloacetic acids (HAA5)
- Lead
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
Claim: Arsenic (Pentavalent)<=50 ppb Reduction
For: Arsenic
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claim: Arsenic (Pentavalent)<=50 ppb Reduction
For: Arsenic
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
At the tap, or for the whole house?
These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you
Everything else. Nitrate results here are Utah’s own from 2020 on, with EPA’s national file for 2012 to 2019. Arsenic, fluoride, total trihalomethanes (TTHM), chromium (total) and haloacetic acids (HAA5) come from EPA’s file alone, which ends in 2019. Bothwell Town 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 Aug. 24, 2020 to Feb. 20, 2026; EPA’s compliance samples are from Aug. 11, 2014 to June 10, 2019.
