What Is Hard Water and How Hard Is Tucson Water?
Hard water is water with high levels of dissolved calcium and magnesium. Tucson Water rates its own supply as hard to very hard. On the city’s scale, water from 120 to 180 mg/L is hard and anything above 180 mg/L is very hard. To convert mg/L to grains per gallon, divide by 17.1.
In the homes Desert Water Services tests, Tucson water usually measures 10 to 15 grains per gallon, well above the 7 grain level where water is considered hard. The cause is geology. Tucson’s supply blends Colorado River water delivered by the Central Arizona Project with local groundwater, and as that water moves through desert soil and rock, it picks up calcium and magnesium.
Signs of Hard Water in Tucson Homes
The most common signs of hard water are white crust on faucets, showerheads, and glass doors, cloudy spots and film on dishes, soap and shampoo that do not lather well, stiff laundry, and dry skin or dull hair. Outdoor misters and faucet aerators clog, and water heaters lose efficiency as scale builds up inside. If you notice two or more of these signs, a free water test will confirm your exact hardness level.
Does a Hard Water Filter Remove Hardness?
No, a standard carbon filter does not remove hardness. A carbon hard water filter reduces chlorine, taste, and odor, but calcium and magnesium pass right through it. To remove hardness from the whole house, you need a water softener or a system designed for hard water. Reverse osmosis reduces hardness minerals at one drinking water tap, not throughout the home.
