Verona Water Hardness & Quality Report (2026)

The City of Verona Waterworks supplies the municipality of Verona, drawing its water exclusively from groundwater. This supply originates from deep aquifer systems characteristic of south-central Wisconsin, specifically the Cambrian–Ordovician carbonate aquifer. The water passes through treatment processes at the utility's main facility, located at 410 Investment Court, Verona, WI 53593. Annual Consumer Confidence Reports are published by the City of Verona Waterworks, detailing water quality monitoring and treatment practices for residents.

The groundwater originates from the Cambrian–Ordovician aquifer system, which is rich in dolomite and limestone formations. These highly soluble carbonate minerals, primarily calcium and magnesium carbonates, readily dissolve as water moves through the soil and bedrock. This geological characteristic, prevalent in the ancient marine limestone and dolomite deposits of the region, is the main reason for the naturally very hard water supply found in Verona.

Homeowners in Verona will likely notice scale buildup on faucets and showerheads, along with reduced lathering from soaps and detergents. Mineral deposits can also appear on dishes and glassware after washing. Appliances like water heaters, dishwashers, and washing machines are susceptible to scale accumulation, which can decrease their efficiency and shorten their operational life. Many households find that installing a water softener significantly reduces these issues and lowers maintenance expenses. For those without a softener, regular descaling of appliances and the use of chelating agents can help manage scale buildup. Residents can find detailed water quality data, including pH and lead/copper results, in the annual Consumer Confidence Report or by contacting Scott Gunsolus.
