What Makes Verona's Water Unique?
Local geology and source profile
Verona, Wisconsin, in Dane County — a Dane County city adjacent to Madison and Fitchburg in south-central Wisconsin — receives its water from the City of Verona Water, drawing from the Niagaran Dolomite aquifer (Dane County) through the south-central Wisconsin distribution.
The hard 161 mg/L hardness and TDS of 432.8 mg/L reflect the south-central Wisconsin Dane County Silurian dolomite groundwater supply's hard dolomitic character — the Silurian Niagaran Dolomite and Ordovician Galena Formation produce hard dolomitic water throughout the Dane County aquifer communities (compare Stoughton WI: 178.5/499 in Dane County comparable; Platteville WI: 201/588 in Grant County harder). The Niagaran aquifer at Dane County — Silurian Niagaran Dolomite (dolomitic — primary hardness contributor), Ordovician Galena Formation (calcareous — secondary contributor), and Cambrian Jordan Sandstone (insoluble — dilutant at base).
At 161 mg/L with TDS 433, Verona's water is hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 4.5 ppt warrants a certified drinking water filter — the Dane County south-central Wisconsin urban-industrial corridor contribute to Verona's elevated readings.
Geology & Source: Verona in Dane County draws from the City of Verona Water on the Niagaran Dolomite aquifer (Dane County, south-central Wisconsin) — the Silurian Niagaran aquifer at Dane County is developed in Silurian Niagaran Dolomite (dolomitic) and Ordovician Galena Formation (calcareous) — Wisconsin Dane County Niagaran Dolomite Silurian dolomitic aquifer produces hard water at 161 mg/L with TDS 432.8 mg/L.
