Finnish waterworks use lake water, often treated or recharged through glacial esker deposits, or natural groundwater. Hardness here is above what the mostly granite bedrock would suggest, so local deposits or the supplier's source are likely to play a role. The figure shown, 62.5 mg/L CaCO₃, is the median across 2 supply zones, which range from 35.7 to 89.2 mg/L, so it depends on which zone your street is in. Kettles and shower screens collect some limescale over time, and regular descaling is usually enough.
Finnish waterworks report hardness in °dH; most supplies are soft.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
