Wisconsin well rules in brief

The DNR says protecting and maintaining a private well is largely the owner's job. (Source: Owners are responsible) Read the Wisconsin well rules.

A Wisconsin pump installer license requires passing a DNR exam with a score of 75% or higher. (Source: Pump installer license by exam) How well contractors are licensed in Wisconsin.

Testing your well water in Wisconsin

The Wisconsin State Laboratory of Hygiene tests private well water for homeowners. Its total coliform and E. coli test costs $35 with about 2 business days of testing time. (Source: State Lab of Hygiene bacteria test)

We have not yet collected published test fees for Wisconsin. Published fees in other states show what labs charge. Which tests fit your home.

How deep wells are in Wisconsin

The Wisconsin Department of Natural Resources has 485,513 logs for new and replacement private drinking water wells. The median well among them is 120 feet deep, and the middle 80% run from 46 to 259 feet. The median static water level is 32 feet below the ground. Well depth and water level for every Wisconsin county, with the method, limits and a CSV.

Well logs cover drilled wells reported to the state, not every well. Source: Wisconsin Department of Natural Resources, read October 10, 2026.

  • 1,353 entries on the list, covering 1,588 licensed people, 89 of them based outside Wisconsin.

Questions

How do I check that a well pump installer is licensed in Wisconsin?

The Wisconsin Department of Natural Resources publishes the list of licensed drillers and pump installers. We read it on October 7, 2026; every name in the table below comes from it, with the license classes the state gives. Ask any business for its license number before work starts.

How many licensed well pump businesses are there in Wisconsin?

The Wisconsin Department of Natural Resources list we read shows 1,232 businesses or licensees based in Wisconsin whose license covers well pump work, and 262 that hold a water well drilling license or class. Firms licensed only for monitoring, geotechnical or geothermal work are left out.

Does Wisconsin require private well owners to test their water?

Not when a home is sold: Wisconsin law does not require well water testing at a property sale. The DNR recommends testing for bacteria and nitrate once a year and for arsenic once every five years.
