DETECTION AND DEFINITION
Hardness in water
Hardness in water primarily originates from dissolved minerals such as calcium and magnesium. These minerals dissolve into the water as it passes through rocks and soil. Detection of hardness levels can be accomplished using various methods including testing kits, water analysis conducted by laboratories, or even through visual indicators such as the presence of scale deposits on faucets and appliances. Measurement units for hardness typically include milligrams per liter (mg/L) or parts per million (ppm), indicating the concentration of dissolved minerals in the water.
