What is Hard Water?

Water hardness is a measure of the concentration of specific minerals, typically calcium and magnesium, in water. This measure is crucial because the higher the mineral content, the harder the water. The Water Quality Association (WQA) uses the water hardness scale to classify the hardness of water, ranging from soft to very hard

Drinking Hard Water

Can you drink hard water? Yes, hard water is generally safe to drink. In fact, the mineral content found in hard water can even provide essential nutrients for the body. However, it's crucial to understand the effects of hard water on our systems. Drinking very hard water may contribute to specific health concerns, such as the accumulation of certain minerals in the body. It's always a good idea to check your local water quality report and consult with health professionals if you have concerns about your water's mineral content.

Calculating Water Hardness

Not every state mandates reporting water hardness in annual consumer confidence or water quality reports. However, understanding water hardness can be vital for household and industrial uses. To calculate water hardness, you need to determine the concentration of dissolved magnesium and calcium in a water sample. The formula for water hardness calculation is: Water hardness (mg/L) = Ca(mg/L) x 2.497 + Mg(mg/L) x 4.118.
