The Basics

What Is Hard Water, Exactly?

It Is Mineral-Rich Water

Hard water contains high concentrations of calcium and magnesium ions picked up as groundwater passes through limestone and chalk rock formations.

85% of US Homes Have It

The USGS maps show that nearly all of the Midwest, Southwest, and South have water classified as hard or very hard. Only the Pacific Northwest regularly has soft water.

It Causes Real Damage

Hard water leaves mineral deposits on hair, clogs skin pores, reduces water heater efficiency by up to 29%, and shortens appliance lifespan.

It Is Solvable

From a $30 test kit to a $1,500 whole-house softener, there is a solution for every budget and living situation.
