Well Construction Information
These links allow you to search electronic databases for well construction reports (a.k.a. well logs). The well construction reports will have the name of the property owner when the well was drilled. If it is an older well (pre-1988) you may not find a well construction report the appears to match since some of those records are missing or incorrectly filed for various reasons. The less information you enter, the better to find the report.

Well Inspection/Compliance Information
Generally, during real estate transactions wells are inspected to determine if they are code compliant. You can read more about property transfer well inspections on our website: http://dnr.wi.gov/topic/Wells/RETransfer.html. If you would like to know if a well is currently code compliant, I recommend that you contact a licensed well driller or pump installer that has indicated they are willing to do inspection work by viewing the list of “Well System Inspectors” on the bottom of this webpage: http://dnr.wi.gov/topic/Wells/contacts.html. The list is sorted by county so that should make it easier to find someone local.
