The Health Department operates a State of Wisconsin Certified Water Lab for the bacterial analysis of both public and private well water supply. 

How can I tell if my well water is safe to drink?
You’ll only know by having it tested at a Certified Lab. Wells are generally a safe and dependable source of drinking water – but the best way is to have your well water tested annually for bacteria. For more information see our well water test brochure
