Soft Water in Nouvelle-Aquitaine: Should You Still Protect Your Home?
With a hardness of 15–30°f, water in Nouvelle-Aquitaine is soft to moderately hard. Limescale is less problematic than in Île-de-France or the North, but:
- Some municipalities may have harder water than the regional average
- Soft water can be aggressive (negative Langelier index), promoting corrosion
- LIMPEO also protects against micro-deposits that accumulate over the long term
