Washington vs Bolingbrook Water Quality
Side-by-side water quality comparison for two Illinois cities.
If you are comparing Washington and Bolingbrook water quality - whether moving, choosing between the two, or curious about a relative's water - here is what the data shows.
Hardness comparison
Washington has somewhat harder water at 380 PPM versus Bolingbrook at 350 PPM, a difference of 30 PPM. At 380 PPM, Washington 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. Bolingbrook also has hard water but to a lesser degree.
Both cities have hard water, but Washington's higher hardness means more aggressive scale buildup and higher household impact.
Water sources and why they differ
Water sources differ: Washington draws from Deep wells, while Bolingbrook uses Lake Michigan via DuPage Water. Both use similar source types, but local geology creates the hardness variation.
What this means for you
If you are moving from Bolingbrook to Washington, you will notice the water difference. Budget for a water softener and expect to use more soap and detergent until you install one.
