What Makes Menomonee Falls's Water Unique?
Local geology and source profile
Menomonee Falls, Wisconsin, in Waukesha County — a major north Waukesha County suburban community northwest of Milwaukee (Menomonee Falls is one of the larger Waukesha County suburbs — a primarily residential community in the rapidly growing Waukesha County corridor), home of several major corporate campuses (Kohl's Corporation, one of the largest US department store chains, was headquartered in Menomonee Falls for many years), a diverse Waukesha County community, and a major commercial and residential community along US-41 in the north Milwaukee suburban corridor — draws its municipal water supply from the deep Silurian Niagara Dolomite aquifer via the Village of Menomonee Falls Water Division. Water hardness in Menomonee Falls measures 236.5 mg/L — classified as very hard.
Menomonee Falls's very hard supply reflects the Waukesha County Silurian Niagara Dolomite aquifer's highly calcareous character. The Silurian Niagaran Dolomite (the Lockport Dolomite formation in Waukesha County — a regionally extensive, highly calcareous dolomite of the Lake Michigan basin) is the primary deep aquifer for most Waukesha County communities not connected to Lake Michigan supply. The deep Waukesha County Niagaran Dolomite well supply produces the very hard 236.5 mg/L.
At 236.5 mg/L, Menomonee Falls residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. Village of Menomonee Falls Water Division consistently delivers water meeting all Wisconsin DNR and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Silurian Niagara Dolomite Aquifer via the Village of Menomonee Falls Water Division — the Waukesha County north Milwaukee suburban corridor (Silurian Niagara Dolomite — Lockport Formation — the highly calcareous northeast Wisconsin–Illinois dolomite bedrock; deep Waukesha County calcareous dolomite supply); very hard supply at 236.5 mg/L in Waukesha County.
