Hard water, which is water with a high mineral content, is also known as calcareous water. This term comes from the fact that the most common minerals found in hard water are calcium and magnesium, which are derived from limestone, chalk, or gypsum.
Hard water can also be referred to as:
- Limescale water: This term specifically refers to the calcium carbonate deposits that form when hard water is heated.
- Scale water: This is a general term for any mineral deposits that form on surfaces exposed to hard water.
