Local geology and source profile
Fitchburg, Wisconsin, in Dane County — a major south Madison suburban community (Fitchburg is a significant Dane County city — a south Madison suburb adjacent to Madison on the south side; Fitchburg is one of the rapidly growing Dane County suburban communities that has expanded as Madison's technology, university, and government sector economy has grown; Fitchburg is home of the Epic Systems campus area (Epic Systems Corporation — one of the most important healthcare information technology companies in the United States; Epic is headquartered in nearby Verona just to the west, but its presence shapes the economic and residential character of the entire south Dane County suburban belt including Fitchburg)), a diverse Dane County community with a primarily technology professional, University of Wisconsin-affiliated, and growing international population (Fitchburg has seen significant growth in its Indian-American and Chinese-American professional population as Epic and UW research employment has expanded), adjacent to Verona and Madison in the south Dane County corridor — draws its municipal water supply from the Prairie du Chien–Jordan Aquifer via the City of Fitchburg Water Utility. Water hardness in Fitchburg measures 107 mg/L — classified as moderately hard.
Fitchburg's moderate hardness reflects the south Madison Dane County Paleozoic Platform aquifer's calcareous character. The Prairie du Chien–Jordan Aquifer draws from the Ordovician Prairie du Chien Dolomite (calcareous) with effective treatment, producing the moderate 107 mg/L.
At 107 mg/L, Fitchburg residents encounter moderate scale accumulation. Monthly cleaning is recommended. City of Fitchburg Water Utility consistently delivers water meeting all Wisconsin DNR and EPA Safe Drinking Water Act requirements.
