Mount Pleasant, Utah Water Hardness & Water Softener Guide
Mount Pleasant does not publish a hardness figure. State lab sampling of the individual wells and springs that feed the city has returned 224-344 mg/L as CaCO3 — a spread, not a single tap number.

Why there is a range and not a number
Mount Pleasant 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: Acid House Well 312 in 2024 and Cemetery Well 232 in 2010 are the only modern results.
Your tap receives a blend, so treat the range as the bracket your water falls inside, not as your number.
What Mount Pleasant’s hardness means in practice
Sizing is arithmetic once you have a number. At 20.1 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 6,035 grains of hardness through its plumbing every day. Over a year that is about 315 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 5.3 days and a 48,000-grain unit about every 8.0 days. Those are first estimates off the figure Mount Pleasant 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 Mount Pleasant
The state samples bracket Mount Pleasant’s sources across a wide range and your tap gets a blend, so we size to your reading rather than to the bracket.
