The short answer

1 result is above the limit’s level with no violation recorded, and 1 more is above the health goal. The worst: Haloacetic acids (HAA5), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2011 to 2023.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.8 ppm, for the period ending Dec. 31, 1999. None since is on file, so it is not counted as a current finding.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, arsenic, chromium (total) and fluoride: Wisconsin’s own results, samples taken from March 18, 2020 to July 20, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the limit’s level, no violation

66.8ppb

Highest yearly average, 2022 to 2026

2026 average: 34.5 ppb

Averaged by year, the highest was 66.8 ppb, in 2025, above EPA’s legal limit of 60 ppb. In 2026, the latest year on file, its two samples averaged 34.5 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for haloacetic acids (HAA5) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.1 ppb, in 2019.

Above the health goal1

Above the health goal

6.3ppb

90th percentile, 2023

In the latest period, 9 in 10 homes sampled were at or below 6.3 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

32.8ppb

Highest yearly average, 2021 to 2026

2026 average: 16.2 ppb

Averaged by year, the highest was 32.8 ppb, in 2025, below EPA’s legal limit of 80 ppb. In 2026, the latest year on file, its two samples averaged 16.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 10.7 ppb, in 2016.

The highest sample, in 2025, was 2.9 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its two samples averaged 1.3 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 2.9 ppm, in 2014.

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?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

Hardness

Soft, typically 20 mg/L (1.2 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. There are 5 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, arsenic, chromium (total) and fluoride results here are Wisconsin’s own from 2020 on, with EPA’s national file for 2012 to 2019. WI Air National Guard Volk Field’s own annual report, which it must send you every year, has 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 March 18, 2020 to July 20, 2026.

Testing your own tap

WI Air National Guard Volk Field’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.

No lab Wisconsin certifies is within 75 miles of the area WI Air National Guard Volk Field serves on the state’s list. Some take samples by mail; the state’s page lists them all.

Wisconsin State Laboratory of Hygiene: Well water test kits ordered by phone and shipped free; you pay to mail the sample back, and the lab bills you after testing. Tests run from bacteria alone to a homeowner package covering bacteria, nitrate, fluoride, metals, hardness, volatile organic compounds and atrazine. Bacteria is $35, nitrate $35, lead $38, and the homeowner package $450, as of July 1, 2026. Public Environmental and Water Testing Prices, Wisconsin State Laboratory of Hygiene.
