The short answer

Nothing in EPA’s and Wisconsin’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 2 health-based violations since 2016.

What was found

Fluoride, arsenic, chromium (total) and nitrate: Wisconsin’s own results, samples taken from Sept. 23, 2020 to Sept. 25, 2024, with EPA’s 2012 to 2019 file for earlier years.

Hardness

Hard, typically 150 mg/L (8.8 grains per gallon), across 3 sampling points, in 2018.

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. Fluoride, arsenic, chromium (total) and nitrate results here are Wisconsin’s own from 2020 on, with EPA’s national file for 2012 to 2019. 52nd Ave Water Group’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 Sept. 23, 2020 to Sept. 25, 2024.

Testing your own tap

52nd Ave Water Group’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 52nd Ave Water Group 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.
