Kamas, Utah Water Hardness & Water Softener Guide
Kamas does not publish a hardness figure. State lab sampling of the individual wells and springs that feed the city has returned 211-257 mg/L as CaCO3 — a spread, not a single tap number.

Why there is a range and not a number
There is no citywide number for Kamas — only per-source state lab results, which vary by well. Your tap gets a blend. How to read a range.
Worth knowing: 211 is Left Hand Fork Spring 2025; the two wells date to 1991 and 1996.
Your tap receives a blend, so treat the range as the bracket your water falls inside, not as your number.
What Kamas’s hardness means in practice
Sizing is arithmetic once you have a number. At 15.0 grains per gallon — the top of that range, because a softener sized for the soft months lets hardness through in the hard ones — a household using the EPA average of more than 300 gallons a day sends roughly 4,509 grains of hardness through its plumbing every day. Over a year that is about 235 pounds of scale-forming calcium and magnesium passing through the water heater and the fixtures.
Against that load a 32,000-grain softener would regenerate roughly every 7.1 days and a 48,000-grain unit about every 10.6 days. Those are first estimates off the figure Kamas publishes, not a quote: your own use, any iron in the water, and whether you want softened water at the kitchen tap all move the answer, which is why we measure at your tap before sizing anything.
What CASA recommends in Kamas
Kamas’s sources test differently from one another, which makes a single figure meaningless for your address. We measure, then size.
