What Makes Pleasant Prairie's Water Unique?
Local geology and source profile
Pleasant Prairie, Wisconsin, in Kenosha County — a Kenosha County village adjacent to the Illinois-Wisconsin border, a fast-growing suburban community with the LakeView Corporate Park (one of the largest corporate parks in the Midwest) and major Amazon and retail distribution centers — receives its municipal water from the Pleasant Prairie Water Utility, which draws from deep groundwater wells in the Silurian Niagara Dolomite aquifer or the Cambrian-Ordovician sandstone aquifers beneath the Kenosha County lakefront corridor.
The hard 206.5 mg/L hardness and high TDS of 611 mg/L reflect Kenosha County's Silurian dolomite and Cambrian deep aquifer character — consistently hard throughout the southeastern Wisconsin lakeshore corridor. The Silurian Niagara Dolomite — the same Niagara Group that creates Niagara Falls and produces hard water throughout the Great Lakes region — underlies Kenosha County at relatively shallow depths, while deeper Cambrian Mount Simon Sandstone wells access the ancient Precambrian-Cambrian confined aquifer system (which can have elevated dissolved solids from long subsurface residence times). The Kenosha County water table receives limited recharge through thin Wisconsin glacial till over this Silurian dolomite bedrock.
At 206.5 mg/L with TDS 611 mg/L, Pleasant Prairie's water is hard — scale builds in kettles and appliances within weeks, dishwashers require rinse aid or softener salt, and showerheads need periodic descaling. Monthly descaling is practical. A water softener is recommended. The PFAS level of 5.5 ppt warrants a certified drinking water filter — the Kenosha County Illinois border industrial zone (Abbott Laboratories, Amazon distribution), Great Lakes Naval Station (Waukegan-Lake County, Lake Michigan AFFF source), and the Lake Michigan southeastern Wisconsin corridor's industrial PFAS legacy contribute to Pleasant Prairie's reading.
Geology & Source: Pleasant Prairie in Kenosha County draws from Pleasant Prairie Water Utility on the Mount Simon Sandstone or Niagara Dolomite aquifer (Silurian) — the Silurian Niagara Dolomite and Cambrian Mount Simon Sandstone aquifers underlie the Kenosha County bedrock beneath thin Wisconsin glacial till — Silurian dolomite and Cambrian deep sandstone aquifer produces hard water at 206.5 mg/L with high TDS 611 mg/L in this Kenosha County Wisconsin village.
