The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 2.1 ppm, for the period ending June 30, 2008. None since is on file, so it is not counted as a current finding.

Arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), chromium (total) and nitrate: Wisconsin’s own results, samples taken from April 6, 2020 to Aug. 6, 2026, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from Feb. 8, 2012 to May 8, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

0.77ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 0.77 ppb, in 2026: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 2.3 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.7 ppb, in 2014.

2019, one sample: 0.48 ppb

Averaged by year, the highest was 0.54 ppb, in 2018: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2019, the latest year on file, its one sample was 0.48 ppb.

2026 average: 0.95 ppm

Averaged by year, the highest was 1.0 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 1.3 ppm. In 2026, the latest year on file, its three samples averaged 0.95 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.0 ppm, in 2017.

  • 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.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Uranium

    For: Arsenic, Uranium

    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.

Hardness

Very hard, typically 255 mg/L (14.9 grains per gallon), across 3 sampling points, 2017 to 2026.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

Violations since 2016

No health-based violations on file with EPA since 2016.

What this report can’t tell you

  • Everything else. Arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), chromium (total) and nitrate results here are Wisconsin’s own from 2020 on, with EPA’s national file for 2012 to 2019. Uranium comes from EPA’s file alone, which ends in 2019. Village of Bristol Waterworks’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; Wisconsin’s results run from April 6, 2020 to Aug. 6, 2026; EPA’s compliance samples are from Feb. 8, 2012 to May 8, 2019.

Testing your own tap

Village of Bristol Waterworks’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 Wisconsin certifies.
