Falu Energi och Vatten lists hardness for each of its waterworks, and the plant serving Falun town is Lennheden/Tjärna, at 131.7 mg/L CaCO₃. The utility labels it medium-hard. The same plant appears in Borlänge's figures, which differ slightly because the sampling is different. The page gives no year or sample count, so we date it to its February 2026 update.
Swedish municipalities report °dH; most surface-water supplies are soft.

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).
