Medina vs Delaware Water Quality

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

Hardness comparison

Medina has somewhat harder water at 340 PPM versus Delaware at 320 PPM, a difference of 20 PPM. At 340 PPM, Medina 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. Delaware also has hard water but to a lesser degree.

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

Water sources and why they differ

Water sources differ: Medina draws from Local wells, while Delaware uses Olentangy River + wells. Both use similar source types, but local geology creates the hardness variation.

Contaminant concerns

PFAS contamination is a concern in Medina (15.5 ppt, above the EPA limit of 4 ppt). A reverse osmosis system or NSF P473-certified filter is recommended for drinking water.

What this means for you

If you are moving from Delaware to Medina, you will notice the water difference. Budget for a water softener and expect to use more soap and detergent until you install one.
