Where the water comes fromGround water in Cape Girardeau

A ground water system on this scale is usually pulling from a well field rather than a single bore, and the hardness of what it delivers reflects the aquifer underneath it rather than anything the treatment plant does.

Cape Girardeau PWS serves 17,002 service connections and is one of 4 community systems in the town. The number is self-reported to the EPA and current to 2026 Q2.

What to do with thatGet your hardness figure

Cape Girardeau PWS publishes an annual water quality report and the hardness figure is in it, so this costs you nothing but the time to look. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.

Next, the calculation — people, gallons, grains. It is the difference between a checkable quote and a trusted one. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
