What is Hard Water?

Hard water contains high levels of dissolved minerals, primarily calcium and magnesium. These minerals are picked up as water travels through the ground, dissolving rocks like limestone and chalk. While hard water is not harmful to health, it can cause numerous problems in a household, affecting everything from plumbing to personal care.

The Origins of Hard Water

The minerals in hard water originate from the natural geological processes of the earth. As rainwater travels through soil and rock, it dissolves small amounts of naturally occurring minerals, which then become part of the groundwater supply. Areas with significant limestone, chalk, or gypsum deposits are more likely to have hard water.
