What is hard water?

As we navigate through 2026, understanding the quality of your home's water is more important than ever. In the natural water cycle, water picks up minerals from rocks and soil, including hard minerals like calcium and magnesium. When the concentration of these minerals is high, the water is known as hard water; when the concentration is low, it’s called soft water.

How can I tell if I have hard water?
- Soap Scum: Hard water often leaves a white or gray residue on sinks, showers, and dishes. The minerals in hard water react with soap, reducing its effectiveness and causing scum.
- Lack of Lather: You might have hard water if your shampoo or soap doesn’t lather well.
- Dry Skin and Hair: After washing, you might notice that your skin feels dry, rough, and tangled. This could be a result of mineral buildup from hard water.
