Although calcium and magnesium are the biggest contributors to water hardness, there are many other deposits in the earth that can contribute to making water hard, such as aluminum, iron, and zinc. Even though these and other minerals will add hardness to water, the amount of hardness that they will add to the overall hardness of water is minimal c...
The amount of hardness that is contained in any given sample of the water will vary depending on the amount of hardness contributing deposits that it has come in contact with and its ability to dissolve and absorb the minerals that make water hard. Water is often called the ultimate natural solvent. It has the ability to dissolve multiple substance...
Temporary hardness is the presents os high concentrations of dissolved calcium and magnesium hydrogen carbonate. These hydrogen carbonates can be removed from the water through the process of boiling the water. Boiling the water will dissipate these hydrogen carbonates and remove them from the water. This water hardness is considered temporary beca...
Permanent hardness is the presence of hard minerals in the water that cannot be removed through the process of boiling the water. Permanent hardness is most often water containing calcium or magnesium sulfates. These sulfates will not precipitate from the water due to an increase in water temperature. The calcium or magnesium sulfates in water that...
Actually, the two primary minerals that make water hard are essential for our health. Both calcium and magnesium are highly beneficial to our overall well being. Many people prefer the taste of hard water because they believe that it is more flavorful than softened water and contains less salt. But this usually depends on the number of hard mineral...
Absolutely! Just because water has had the minerals that it make it hard removed from it does not mean that it is no longer ok to drink. Some people think that softened water is not healthy to drink because the process of softening water adds lots of salt to the water. This is not at all the case. The salt that the water softener uses is only to re...
Have you ever heard of soap scum? No, not the bad guys on daytime television. I’m talking about that sticky ring around the bathtub after you have taken a bath in hard water. That yucky ring of soap scum is not there just because you used soap while taking a bath. It’s there because the hard minerals in your water combine with the soap that you use...
Water hardness can build-up inside your pipes and hot water heater. If you have hard water running through your home’s plumbing, the hardness can collect in any tiny scratch or dimple that may be in your pipes. A simple elbow in the plumbing will have a small ridge where the two pieces of pipe come together. This is a perfect spot for hardness to a...
Hardness build-up in your home’s plumbing can be cleared by running a mild acid through the pipes to dissolve away the build-up. The problem with doing this is that the acid will attack any non-affected areas of your plumbing as well. Most of the time, hardness deposits form in certain areas of your plumbing. Common areas include sharp turns in you...
Absolutely! Changes in rainfall, heavy or light periods of rainfall, any type of construction going on nearby or even miles away can change the route of the water you use. Anytime a water source comes into contact with a new series of minerals, the amount of hardness that it will dissolve will change. Even if just a few new homes are built on your ...

Hard water causes scaling in hot water systems, kettles, electric irons and domestic appliances. Scaling is defined as deposits of calcium and magnesium that build up on...
Measures of water hardness. Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals. General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.
If this occurs, it is usually caused by the presence of calcium sulfate / calcium chloride and/or magnesium sulfate / magnesium chloride in the water, which do not precipitate out as the temperature increases. Ions causing the permanent hardness of water can be removed using a water softener, or ion-exchange column.
May 20, 2024 · The more dissolved minerals, the “harder” your water. But is hard water actually good or bad for you? As engineering researchers who study water quality, we have seen the effects – both...
Jun 30, 2023 · Hard water contains high amounts of minerals in the form of ions, especially the metals calcium and magnesium, which can precipitate out and cause problems in water cconducting or storing vessels like pipes.
