Troy water is pumped from deep wells and comes out VERY hard - about 19 grains per gallon, nearly double the "very hard" line. You feel it everywhere: soap that won't lather, filmy skin and stiff, dull hair after every shower, chalky spots on glasses, and a crust of scale building inside faucets, shower heads and your water heater that quietly kills appliances years early. On top of the hardness it carries naturally high fluoride (2.59 ppm - over the state's dental warning level for kids), dissolved minerals 34% above the EPA's taste limit, high sodium, and radium sitting right at 96% of the federal safety cap. It legally passes, but "passes" is not the same as clean, soft, or great-tasting.

Very hard water (~19 gpg)
High naturally-occurring fluoride (2.59 ppm, above 2.0 dental-fluorosis warning)
TDS 668 ppm (34% over EPA aesthetic limit)
Elevated sodium (124 ppm)

On a private well in Troy: Private wells across rural Lincoln County are not regulated or tested under the Safe Drinking Water Act. Typical problems for this limestone/dolomite and river-alluvium geology: very hard water, iron and manganese (orange/brown staining, metallic taste), hydrogen sulfide "rotten-egg" smell, coliform/E. coli bacteria (the top health risk - UV pitch), nitrates in shallow/ag-area wells (infant blue-baby risk), and the same deep-bedrock radium that shows up in city water - which well owners almost never test for.

How hard is Troy's water?+
Troy tests at 19.2 grains per gallon (gpg) - graded F, or "Extremely hard." Very hard water (~19 gpg)
What else is in Troy's water besides hardness?+
Troy's own city report carries a state-required warning: fluoride is high enough (2.59 ppm) that children under 9 should drink an alternative water source to avoid permanent tooth staining - and the same deep bedrock pushes radium to 96% of the federal limit. Parents of young kids do not have to accept that.
