How do I obtain a Wisconsin unique well number for several new monitoring well that were recently installed at my facility?

Well drillers have lists of Wisconsin unique well numbers (WUWNs) they are supposed to assign to each monitoring well they install. Check with the well driller or consultant to see if a WUWN has been assigned. If the well driller has not assigned a WUWN, you may obtain one for a given monitoring well by contacting the hydrogeologist assigned to your site. The hydrogeologist obtains the numbers from a list maintained in the Waste and Materials Management Madison office by the GEMS Technician. Contact Jack Connelly or 608-267-7574 if you have questions.
