The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Nitrate, above the legal limit. 1 health-based violation since 2016.

What handles it

What was found

Nitrate, arsenic, haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride and chromium (total): Wisconsin’s own results, samples taken from Jan. 22, 2020 to June 9, 2026, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from April 25, 2017 to April 25, 2017. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Nitrate

Comes from the source

Above the legal limit

13ppm

Highest sample; found in 32 of 32

2026 average: 1.5 ppm

In 2020, three samples were above EPA’s legal limit of 10 ppm, the highest 13 ppm. The next sample at the same point, within 30 days, kept the average above the limit for two; one has no follow-up sample on file within 30 days. In 2026, the latest year on file, its four samples averaged 1.5 ppm. EPA recorded a violation for nitrate at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 10 ppm, in 2019.

Above the health goal2

Arsenic

Above the health goal

0.8ppb

Highest yearly average, 2020 to 2026

2026 average: 0.2 ppb

Averaged by year, the highest was 0.8 ppb, in 2024: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2026, the latest year on file, its four samples averaged 0.2 ppb.

Uranium

Comes from the source

Above the health goal

0.025ppb

Highest yearly average, 2017

Averaged by year, the highest was 0.025 ppb, in 2017: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 0.03 ppb. That is the only year on file.

Haloacetic acids (HAA5)

10.4ppb

Highest yearly average, 2020 to 2024

Averaged by year, the highest was 10.4 ppb, in 2024, below EPA’s legal limit of 60 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 23.6 ppb, in 2016.

12.3ppb

Highest yearly average, 2020 to 2024

Averaged by year, the highest was 12.3 ppb, in 2024, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.2 ppb, in 2016.

Fluoride

Below EPA’s limits

0.11ppm

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 0.11 ppm, in 2026, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.14 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.12 ppm, in 2017.

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

    Claims: Nitrate/Nitrite (30 ppm challenge), Arsenic (Pentavalent)<=50 ppb Reduction

    For: Nitrate, Arsenic

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

  • NSF/ANSI 58

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

    For: Nitrate, Arsenic, Uranium

    Other certifiers’ wording: Nitrate; 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

Soft to moderately hard depending on the source, 35 to 82 mg/L (2 to 4.8 grains per gallon), across 5 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.

What this report can’t tell you

  • Everything else. Nitrate, arsenic, haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride and chromium (total) 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. Augusta 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 Jan. 22, 2020 to June 9, 2026; EPA’s compliance samples are from April 25, 2017 to April 25, 2017.

Testing your own tap

Augusta 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.
