Understanding Water Hardness
What the grains per gallon number actually means for your home.
Soft (0 to 1 gpg)
Rare in the Twin Cities region. Minimal hardness minerals. No softener needed. Found in some surface-water-supplied homes.
Moderately Hard (1 to 7 gpg)
Found in cities served by SPRWS, the Joint Water Commission, or centrally lime-softened municipalities like Bloomington and Eden Prairie. Generally no softener needed at home.
Hard (7 to 10.5 gpg)
Noticeable scale buildup, dry skin, dishware spotting. A water softener is recommended for comfort and to protect plumbing and appliances.
Very Hard & Extremely Hard (10.5+ gpg)
Severe scale, water heater damage, premature appliance failure. A properly sized water softener is strongly recommended. Consider iron filtration and PFAS-certified RO systems depending on city.
