Logan, Utah Water Hardness & Water Softener Guide
Logan has hard water at about 18 grains per gallon — here is what that means for your home and how to fix it.
Where Logan’s water comes from
Logan’s water comes primarily from Logan River/Dewitt Spring and wells. 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 18 grains per gallon hard?
Yes. Water above 7 gpg is considered hard, so Logan at 18 gpg is hard — among the hardest water in the country. 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 Logan
A water softener is recommended to cut scale and protect your 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.
