For Neuffen we use a Eurofins test report published by Stadtwerke Neuffen AG. The sample of 15 January 2024 from the Teis sampling point (Bahnhofstraße 32) gave 135.1 mg/L CaCO₃, about 7.6 °dH. This is a single sample from one point, not an annual mean, so other districts or other times of year may differ. Detergent dosing should follow the hardness range printed on the pack.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

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).
