What Makes Bellevue's Water Unique?
Local geology and source profile
Bellevue, Wisconsin, in Brown County — an unincorporated Brown County community adjacent to Green Bay and De Pere in the Green Bay metro of northeast Wisconsin — receives its water from the Bellevue Water Division, drawing from the Silurian Dolomite Aquifer (Brown County) through the northeast Wisconsin distribution.
The moderately soft 97.5 mg/L hardness and TDS of 224.9 mg/L reflect the northeast Wisconsin Silurian dolomite aquifer's moderate character — softer than the more dolomitic central Wisconsin communities (Fond du Lac: ~200 mg/L) but consistent with the Green Bay area aquifer zone (Green Bay: ~100 mg/L). The Silurian Dolomite Aquifer at Brown County is developed in Silurian Niagara Dolomite (dolomite — primary hardness and TDS contributor), Silurian Mayville Formation (dolomite), and minor Ordovician Prairie du Chien Group (slightly calcareous). The Silurian Niagara Dolomite produces the moderately soft northeast Wisconsin supply.
At 97.5 mg/L, Bellevue's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 3.1 ppt is low — the Brown County northeast Wisconsin Green Bay industrial corridor has limited major AFFF military sources, and the Lake Michigan Green Bay watershed has a relatively low PFAS background compared to southern Wisconsin.
Geology & Source: Bellevue in Brown County draws from the Bellevue Water Division on the Silurian Dolomite Aquifer (Brown County, northeast Wisconsin) — the Silurian aquifer at Brown County is developed in Silurian Niagara Dolomite (dolomite — slightly calcareous) and Silurian Mayville Formation — Wisconsin Brown County Silurian dolomite aquifer produces moderately soft water at 97.5 mg/L with TDS 224.9 mg/L.
