What Makes Richfield's Water Unique?
Local geology and source profile
Richfield, Wisconsin, in Washington County — a Washington County town adjacent to Germantown and Hartford in the Kettle Moraine region of southeast Wisconsin — receives its water from the Richfield Utilities or Washington County Water, drawing from the Kettle Moraine groundwater aquifer through the southeast Wisconsin distribution.
The moderately hard 117.5 mg/L hardness and TDS of 285.1 mg/L reflect the Washington County Kettle Moraine supply's moderate dolomitic character — the Silurian Niagaran Dolomite and Ordovician Prairie du Chien Dolomite are both dolomitic formations that produce slightly less hard water in some Kettle Moraine zones compared to the deeper southeast Wisconsin aquifer (compare Germantown WI: 115/279 in Washington County comparable; Hartford WI: 120/291 in Washington County comparable; Richfield consistent moderate from the same Washington County Kettle Moraine Silurian dolomitic supply). The Kettle Moraine aquifer — Silurian Niagaran Dolomite (highly dolomitic — primary hardness contributor), Ordovician Prairie du Chien Dolomite (dolomitic — secondary contributor), and Quaternary glacial outwash (calcareous — TDS contributor).
At 117.5 mg/L with TDS 285, Richfield's water is moderately hard — mild scale buildup in appliances. Semi-annual descaling is appropriate. The PFAS level of 3.5 ppt is moderate and well-managed. Review the Richfield utilities' annual water quality report for the latest monitoring data.
Geology & Source: Richfield in Washington County draws from the Richfield Water on the Kettle Moraine aquifer (Washington County, southeast Wisconsin) — the Kettle Moraine drains Silurian Niagaran Dolomite (highly dolomitic) and Ordovician Prairie du Chien Dolomite (dolomitic) — Wisconsin Washington County Kettle Moraine Silurian dolomitic supply produces moderately hard water at 117.5 mg/L with TDS 285.1 mg/L.
