Appleton vs Fond du Lac Water Quality

Side-by-side water quality comparison for two Wisconsin cities.

If you are comparing Appleton and Fond du Lac water quality - whether moving, choosing between the two, or curious about a relative's water - here is what the data shows.

Hardness comparison

Appleton has somewhat harder water at 304 PPM versus Fond du Lac at 290 PPM, a difference of 14 PPM. At 304 PPM, Appleton residents should budget for a water softener ($600-$1,500 installed). Without one, expect scale buildup on fixtures, reduced water heater efficiency, and $800-$1,200/year in hidden costs. Fond du Lac also has hard water but to a lesser degree.

Both cities have hard water, but Appleton's higher hardness means more aggressive scale buildup and higher household impact.

Water sources and why they differ

Water sources differ: Appleton draws from Lake Winnebago, while Fond du Lac uses Lake Winnebago & wells. Both use similar source types, but local geology creates the hardness variation.

Contaminant concerns

PFAS contamination is a concern in Appleton (5.9 ppt, above the EPA limit of 4 ppt). A reverse osmosis system or NSF P473-certified filter is recommended for drinking water.
