Where the water comes fromGround water in Dayton

Ground water has spent time in contact with rock, and that contact is what puts calcium and magnesium into it. How much depends on what the rock is made of — limestone country produces the hardest water in the country.

Dayton, City of serves 904 service connections. The system reports that figure to the EPA itself; this is the 2026 Q2 data.

What to do with thatGet your hardness figure

Dayton, City of publishes an annual water quality report and the hardness figure is in it, so this costs you nothing but the time to look. The units differ on purpose-built confusion: mg/L on the report, grains per gallon on the equipment.

Then run the arithmetic: it tells you the capacity you need rather than the capacity you are offered. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
