The short answer

1 result is above EPA’s legal limit. The worst: Lead, above the action level. 8 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2002 to 2023.

Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, arsenic and fluoride: Wisconsin’s own results, samples taken from Sept. 23, 2020 to Sept. 28, 2026, with EPA’s 2012 to 2019 file for earlier years.

Chromium (total): EPA’s compliance monitoring file, samples taken from Sept. 28, 2017 to Sept. 28, 2017. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Lead

Comes from pipes, often your own

Above the action level

31.8ppb

90th percentile, 2023

In the latest period, 9 in 10 homes sampled were at or below 31.8 ppb, above EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

What handles it

Below EPA’s limits3

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

17.5ppb

Highest yearly average, 2020 to 2024

Averaged by year, the highest was 17.5 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 20.3 ppb, in 2014.

What handles it

  • NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

7.8ppb

Highest yearly average, 2020 to 2024

2024, one sample: 3.3 ppb

Averaged by year, the highest was 7.8 ppb, in 2020, below EPA’s legal limit of 60 ppb. In 2024, the latest year on file, its one sample was 3.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.4 ppb, in 2014.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.37ppm

Highest sample; found in 2 of 6

2025: not found

The highest sample, in 2024, was 0.37 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.17 ppm, in 2013.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

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

Very hard, typically 253 mg/L (14.8 grains per gallon), across 2 sampling points, 2017 to 2024.

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. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, arsenic and fluoride results here are Wisconsin’s own from 2020 on, with EPA’s national file for 2012 to 2019. Chromium (total) comes from EPA’s file alone, which ends in 2019. Dodge Sanitary Dist 1’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 Sept. 23, 2020 to Sept. 28, 2026; EPA’s compliance samples are from Sept. 28, 2017 to Sept. 28, 2017.

Testing your own tap

Dodge Sanitary Dist 1’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.
