Mapleton, Utah Water Hardness & Water Softener Guide
Mapleton does not publish a hardness figure. State lab sampling of the individual wells and springs that feed the city has returned 189-320 mg/L as CaCO3 — a spread, not a single tap number.

Why there is a range and not a number
Mapleton publishes no single figure. What exists is Utah Division of Drinking Water lab results for each well and spring, and they differ from one another. How to read a range.
Worth knowing: Per-source values across 10 wells/springs; city CCR has no hardness.
Your tap receives a blend, so treat the range as the bracket your water falls inside, not as your number.
What Mapleton’s hardness means in practice
Sizing is arithmetic once you have a number. At 18.7 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 5,614 grains of hardness through its plumbing every day. Over a year that is about 293 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 5.7 days and a 48,000-grain unit about every 8.6 days. Those are first estimates off the figure Mapleton 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 Mapleton
The state samples bracket Mapleton’s sources across a wide range and your tap gets a blend, so we size to your reading rather than to the bracket.
