The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. 2 health-based violations since 2016.

What handles it

What was found

Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and nitrate: Minnesota’s yearly summaries per water system, 2023 to 2025.

Uranium, fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from Jan. 19, 2012 to Oct. 22, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Uranium

Highest yearly average, 2012 to 2016

2016: not found

Averaged by year, the highest was 1.6 ppb, in 2012: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2016, the latest year on file, it wasn’t found in its one sample.

2019 average: 0.63 ppm

Averaged by year, the highest was 0.96 ppm, in 2012, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 1.0 ppm. In 2019, the latest year on file, its four samples averaged 0.63 ppm.

Highest yearly average, 2023 to 2025

Averaged by year, the highest was 5.8 ppb, in 2025, below EPA’s legal limit of 80 ppb. That was also the latest year on file.

What handles it

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

Below EPA’s limits

1.2ppb

Highest yearly average, 2023 to 2025

Averaged by year, the highest was 1.2 ppb, in 2025, below EPA’s legal limit of 60 ppb. That was also the latest year on file.

What handles it

No certification claim covers this compound yet.

4 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Chromium (total)
  • Lead
  • Nitrate

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. Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and nitrate results here are Minnesota’s own yearly summaries from 2023 on, with EPA’s national file for 2012 to 2019. Uranium, fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Stacy’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; Minnesota’s yearly summaries cover 2023 to 2025; EPA’s compliance samples are from Jan. 19, 2012 to Oct. 22, 2019.

Testing your own tap

Stacy’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 Minnesota certifies.
