Fairbanks is served by Golden Heart Utilities. Its annual consumer confidence report gives hardness of 143 mg/L as CaCO₃, in the hard band. The report lists one value, so seasonal swings are not documented here. Scale in kettles and water heaters is likely to build up over time, and descaling now and then helps.
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.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
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).
