Syracuse draws water from Skaneateles Lake, one of the Finger Lakes, which the state allows to be used without filtration, and supplements it with Lake Ontario water when needed. The lakes' carbonate-rich basin gives hard water at 127 mg/L CaCO₃. Expect scale on kettles and in water heaters.
USGS classes: soft 0–60, moderately hard 61–120, hard 121–180, very hard >180 mg/L.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.

How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
