The short answer
1 result is above EPA’s legal limit. The worst: Nitrate, above the legal limit. 3 health-based violations since 2016.
What handles itWhat was found
Nitrate: Minnesota’s yearly summaries per water system, 2023 to 2025, with EPA’s 2012 to 2019 file for earlier years.
Fluoride, arsenic and chromium (total): EPA’s compliance monitoring file, samples taken from Aug. 28, 2019 to Aug. 28, 2019. Newer results are in the utility’s annual water quality report.
Above the legal limit1
Nitrate
Comes from the source
7.4ppm
Highest yearly average, 2023 to 2025
2025 average: 6.6 ppm
Averaged by year, the highest was 7.4 ppm, in 2023, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, it averaged 6.6 ppm. EPA judges this limit at each sampling point, and recorded violations for nitrate at this utility in 2020 and 2022. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 12 ppm, in 2016, and EPA recorded violations in 2012 and 2018.
What handles it
- NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
- NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
Below EPA’s limits1
Fluoride
Forms or is added in treatment
0.2ppm
Highest yearly average, 2019
Averaged by year, the highest was 0.2 ppm, in 2019, below EPA’s legal limit of 4.0 ppm. That is the only year on file.

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: Nitrate/Nitrite (30 ppm challenge)
For: Nitrate
- NSF/ANSI 58
Claim: Nitrate/Nitrite Reduction
For: Nitrate
Other certifiers’ wording: Nitrate
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 Minnesota’s own yearly summaries from 2023 on, with EPA’s national file for 2012 to 2019. Fluoride, arsenic and chromium (total) come from EPA’s file alone, which ends in 2019. Brookhaven Development’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 Aug. 28, 2019 to Aug. 28, 2019.
