The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. 3 health-based violations since 2016.

What handles it

What was found

Uranium and nitrate: Arizona’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Fluoride, chromium (total) and arsenic: EPA’s compliance monitoring file, samples taken from Nov. 16, 2015 to Nov. 16, 2015. Newer results are in the utility’s annual water quality report.

Above the health goal1

Uranium

Comes from the source

Above the health goal

16ppb

Highest yearly average, 2021

Averaged by year, the highest was 16 ppb, in 2021: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.

What handles it

Below EPA’s limits3

Nitrate

Comes from the source

Below EPA’s limits

4.4ppm

Highest yearly average, 2020 to 2023

2023 average: 3.0 ppm

Averaged by year, the highest was 4.4 ppm, in 2020, below EPA’s legal limit of 10 ppm. In 2023, the latest year on file, it averaged 3.0 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 4.7 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

0.27ppm

Highest yearly average, 2015

Averaged by year, the highest was 0.27 ppm, in 2015, below EPA’s legal limit of 4.0 ppm. That is the only year on file.

What handles it

Below EPA’s limits

3.2ppb

Highest yearly average, 2015

Averaged by year, the highest was 3.2 ppb, in 2015, below EPA’s legal limit of 100 ppb. That is the only year on file.

What handles it

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • 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.”

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.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

What this report can’t tell you

  • Everything else. Uranium and nitrate results here are Arizona’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride, chromium (total) and arsenic come from EPA’s file alone, which ends in 2019. Bidegain Water Company’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; CDC’s yearly averages for Arizona cover 2020 to 2023; EPA’s compliance samples are from Nov. 16, 2015 to Nov. 16, 2015.

Testing your own tap

Bidegain Water Company’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 Arizona certifies.
