County estimate

Water samples from around Utica put hardness at about 100 mg/L (5.9 gpg), which would be moderately hard on the USGS scale. Treat this as a rough guide: it is the median of 386 samples taken across Oneida County, mostly wells and streams, not a test of Utica's treated tap water.

What 100 mg/L means at home

You may see faint white spots on glasses and shower doors after the water dries.

Scale builds up slowly. A kettle or coffee maker needs descaling now and then, maybe every few months.

Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.

What to do about it

Optional. Plenty of households at this level live with it and descale the kettle now and then.

Water softener

Worth a look if spots on glass bother you, or if your tankless water heater manual asks for softer water.

Carbon filter

Improves taste and removes chlorine. It leaves calcium and magnesium in place.
