Well water hardness scale. Those laundered in hard water ones are rough the result of rock encrustations embedded in the fibers spot dishes faucets sinks toilets cars in fact all surfaces with a microscopic film of limestone. Water systems using groundwater as a source are concerned with water hardness since as water moves through soil and rock it dissolves small amounts of naturally occurring minerals and carries them into the groundwater supply water is a great solvent for calcium and magnesium so if the minerals are present in the soil around a water supply well hard water may be delivered to homes. Water hardness can be measured in gpg or ppm but gpg is the most commonly used measurement. Deposits buildup inside water pipes heaters and bathroom and kitchen fixtures.

It takes 17 1 ppm to equal 1 gpg. Formula to measure no of grains to be removed. This range signifies the grain capacity of most water softeners available on the market. No of persons 75 gallons no of gpg mg lit iron total grains to be removed per day.

If a test for hard water is measured in parts per million or milligrams per liter you can take the total hardness level and divide it by 17 1 to get hardness in grains per gallon. A grain of water hardness is comparable to 1 7000th of a pound.
