Gemeindewerke Ainring reports 19.7 °dH (3.51 mmol/l, about 351.6 mg/L CaCO₃) from a network sample taken on 6 May 2026, which the analysis places in the hard band. The same report lists calcium at 109 mg/l and magnesium at 19.3 mg/l. This is a single network sample with no zone breakdown, so it is one data point rather than a long-term average.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
