There is no average, it depends where you are. It should be between 6.9-7.5 ideally.

Data about the hardness of polonium don't exist.
The average temperature of well water can vary depending on factors such as the location of the well and the depth of the water table. However, in most cases, well water tends to be around 50-60 degrees Fahrenheit.
Hardness minerals in water, such as calcium and magnesium, can affect water quality by causing scale buildup in pipes and appliances. To manage hardness minerals effectively, water softening methods like ion exchange or reverse osmosis can be used to reduce their concentration in water.
Granite has a Rockwell hardness of 7, making it one of the hardest rocks. Talc scores a 1 on the scale, being extremely soft, whereas a diamond is rated at 10, the hardest known mineral.
Hardness compares the weight of a mineral with the weight of an equal amount of water
Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.
Magnesium sulfate (MgSo4) does not cause hardness of water.
Boiling water does not affect the hardness of water. Hardness in water is caused by minerals like calcium and magnesium, which remain in the water even after boiling.
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
The hardness of bottled water can vary widely depending on the source. Typically, bottled water has a low to moderate level of hardness, with most falling within the range of 20-100 mg/L of calcium carbonate equivalents. It's best to check the specific water quality report provided by the bottling company for accurate hardness levels.
60 -100 ppm is the currently acceptable hardness level for drinking water in US and Canada.60 -100 ppm is the currently acceptable hardness level for drinking water.
The water supplier can provide you the details on hardness level if you are on municipal water systems, If you are using private water then you can get tested in laboratories. You can even measure it with water hardness testing kits which you need to purchase.
Carbonate hardness is the measure of hard ions associated with carbonate and bicarbonate anions contained in the water.Noncarbonate hardness is the portion of total hardness in water that is not produced by carbonates, but primarily by sulfate anions.
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.

To calculate water hardness in parts per million (ppm), you can use the formula: Hardness in ppm (Hardness in mg/L) x 1.0.
There are two ways to help control water hardness: use a packaged water softener or use a mechanical water softening unit. Packaged water softeners are chemicals that help control water hardness.
