Private Well Testing Day

Why Participate in Calumet County Private Well Testing Day?

A private well should be sampled annually for bacteria at a minimum. This event provides the annual opportunity (and reminder) to "check up" on your homes drinking water supply. Benefits of participating include bottle pick up & drop off convenience, reduced pricing for group testing participants and an education night held about 5 weeks after the event. The education night is an opportunity to learn how to read your results, as well as how to resolve any problems with your water, including plumbing, proper well maintenance and at home-practices to improve your drinking water.
