Hardness is a measure of the amount of calcium and magnesium minerals in water. Groundwater typically has a higher mineral content than surface water. A high concentration of minerals in the water can make it hard to lather, hence the term “hard water.” Soft water, on the other hand, has a low concentration of minerals, and requires extra rinsing to remove soap. Our water is moderately soft, with 65 milligrams per liter of hardness.

If you are connected to a municipal supply, call the water Superintendent, or City Hall. They can either provide the answer, or direct you to the proper individual. Remember the conversion factor: it takes 17.1 PPM to equal 1 GPG. In other words, if your water has 171 PPM calcium in it, divide 171 by 17.1 to get the answer in grains. This example would be 10 grains, or GPG.

Hard water is caused by calcium and magnesium minerals that are dissolved in water. Hard water interferes with laundering, dishwashing, bathing, and personal grooming. Soap and hard water form deposits that are difficult to remove. Hard water also affects appliances. For example, scale can build up in water heaters, causing them to malfunction. Water is softened by passing it through a water softener, which removes calcium and magnesium salts.

PW hardness averages 100-140 mg/l or 6 -8 grains of hardness at its Paducah plant. The hardness level at its Reidland plant has a higher average of 120 - 190 mg/l or 7 - 11 grains of hardness. Total hardness is defined as the sum of calcium and magnesium ion concentrations, expressed as mg/l calcium carbonate. It is the measure of the capacity of water to precipitate soap. Water that is hard will make lathering difficult or "hard" to achieve, hence the term.

Nashville tap water usually ranges from soft to medium hard., This is ACCEPTABLE for MOST freshwater fish and plant species. If the water is too hard for your specific application (such as breeding certain species), simply mix it with deionized water until the required hardness is obtained. Most hobbyists will not have need to measure this particular water quality. Submit New F.A.Q.

There is no maximum value for total hardness of water supplies. There are maximum values for two substances, calcium and magnesium, which cause hard water. In England and Wales all water supplies meet the value for calcium and six supplies exceed marginally the value for magnesium, but as there is no risk to health, a relaxation of the magnesium value has been granted by the Inspectorate for these supplies.

Mesquite's water is considered moderately hard. The hardness level can vary from month to month, but averages between 93 and 134 milligrams per liter. For reference when purchasing a new washing machine, the hardness levels calculate from 5.44 to 7.84 grains per gallon.

Our water is considered to be moderately hard and is running approximately 6.5 grains per gallon (or approximately 110 parts per million). More information can be found here.

Water is considered hard if it contains calcium and magnesium. Both are common elements found in water. According to the Water Quality Association, hard water is water that has hardness minerals in excess of 1 grain per gallon (gpg). Most water supplies range from 3 to 50 gpg. Following are relative levels of hardness: If left untreated hard water will form scaling in water heaters, pipes, boilers, air conditioners, etc.

Yes you can. Mineral buildup is a problem where the water is heated, i.e. in the tank. The water is being cooled in the tubing so mineral buildup is not possible in the tubing. Mineral buildup in the tank can be minimized by using a powerful heater so that you can have low operating temperatures. Mineral buildup is not likely at temperatures below 1400 F.
