Yes, Paris has water that is considered to be on the borderline of hard water.
Water Hardness in Paris Explained
The water hardness in Paris falls between 20 and 30 degrees French. This converts to 80-120 mg/L of calcium. According to the provided reference, this level is "just on the limit to hard water" and is expected to cause some limescale buildup.
Here's a breakdown:
- Hardness Level: 20-30°f (French degrees) / 80-120 mg/L Calcium
- Limescale: Expected to occur.
In conclusion, while not extremely hard, Parisian water does have enough mineral content to be considered slightly hard and can lead to limescale deposits.
