Moab, Utah Water Hardness & Water Softener Guide
Moab has moderately hard water at about 14 grains per gallon — here is what that means for your home and how to fix it.
Where Moab’s water comes from
Moab’s water comes primarily from Colorado River alluvial wells and Ken Lake (Mill Creek). As that water moves through Utah’s mineral-rich geology it picks up calcium and magnesium — the minerals that make water hard and leave scale behind.
Is 14 grains per gallon hard?
Yes. Water above 7 gpg is considered hard, so Moab at 14 gpg is moderately hard — well above the national average. Hard water shortens the life of water heaters and appliances, spots dishes and glass, clogs fixtures, and dries skin and hair.
What CASA recommends in Moab
A water softener is optional here but improves taste and protects fixtures and appliances. For drinking and cooking, pair it with a reverse-osmosis system, and add whole-home carbon filtration to remove chlorine taste and odor at every tap.
