What Makes Little Chute's Water Unique?
Local geology and source profile
Little Chute, Wisconsin, in Outagamie County — an Outagamie County village in the Fox Valley adjacent to Appleton and Kaukauna on the Fox River in east-central Wisconsin — receives its water from the Village of Little Chute Water Department, drawing from the Silurian Dolomite Aquifer through the Fox Valley distribution.
The very hard 253 mg/L hardness and very high TDS of 819.2 mg/L reflect the Outagamie County dolomite aquifer supply's extreme dolomitic character — the Silurian Niagaran Dolomite and Ordovician Prairie du Chien Dolomite are highly dolomitic formations in the Wisconsin Dolomite Plateau, and deep Fox Valley wells penetrate these formations to produce some of the hardest water in the state (compare Appleton WI: 249/808 in Outagamie County comparable; Kaukauna WI: 256/830 in Outagamie County comparable; Little Chute consistent very hard from the same Outagamie County Silurian Niagaran aquifer supply). The Fox Valley dolomite aquifer — Silurian Niagaran Dolomite (highly dolomitic — primary hardness contributor), Ordovician Prairie du Chien Dolomite (highly dolomitic — secondary contributor), and Quaternary Fox River alluvium (calcareous — TDS contributor).
At 253 mg/L with TDS 819, Little Chute's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 6.6 ppt warrants a certified drinking water filter. Review the Village of Little Chute's annual water quality report.
Geology & Source: Little Chute in Outagamie County draws from the Little Chute Water on the Silurian Dolomite Aquifer (Outagamie County, east-central Wisconsin) — the Fox Valley aquifer draws from Silurian Niagaran Dolomite (highly dolomitic) and Ordovician Prairie du Chien Dolomite (highly dolomitic) — Wisconsin Outagamie County Silurian Niagaran aquifer produces very hard water at 253 mg/L with TDS 819.2 mg/L.
