Hard Water in Minnesota: A Guide to Choosing a Water Softener
How to measure hardness, evaluate scale concerns, and choose a softener for your own water and household.
Hardness varies by utility, private well, and existing treatment. A softener can reduce calcium and magnesium when measured hardness and scale concerns justify it. There is no automatic requirement for every Twin Cities home to install one.
Measure before comparing equipment
Ask your utility about delivered-water hardness or test the water at home. Check whether the sample is taken before or after an existing softener. Keep the units with the result so a plumber can interpret it correctly.
The USGS classifies water using milligrams per liter as calcium carbonate: up to 60 is soft, 61 to 120 moderately hard, 121 to 180 hard, and above 180 very hard. Those categories describe mineral content; they are not health-risk ratings or instructions to buy equipment.
What a softener changes
Ion-exchange softeners reduce calcium and magnesium. This can address scale and soap-lather problems. The unit periodically regenerates its resin using salt or potassium chloride according to its design.
A softener does not provide a complete contaminant assessment or make every water supply safe to drink. PFAS concerns require a separate testing and treatment decision.
Compare the right details
Ask the installer to explain the capacity at the proposed operating settings, rated service flow, regeneration method, space and drainage requirements, and upkeep. Household demand and measured water chemistry matter together. A city average does not establish the correct size for your home.
Request the exact model’s performance information and warranty. There is no reliable sitewide promise that a softener will add a fixed number of years to every appliance or save a fixed percentage on energy.
Consider salt and household preferences
Sodium-based softening adds sodium to water. Ask a healthcare professional about drinking softened water if sodium is a medical concern. An unsoftened drinking-water tap or appropriate separate treatment may be relevant.
Softener discharge also contributes chloride to wastewater. Follow the manufacturer’s settings and avoid unnecessary softening. If your utility already supplies softened water, additional treatment may offer little benefit.

Start with the right test
The free basic in-home test checks hardness, iron, chlorine, pH, total dissolved solids, and alkalinity, plus nitrate for well-water customers. It does not measure PFAS or establish drinking-water safety.
A.J. Alberts offers separate paid PFAS testing for municipal-water and private-well customers. We collect and submit the sample and explain the laboratory report. Ask about the scope and price when booking.
Schedule a free basic water test or call 651-738-0580. For PFAS testing, identify that request when you contact us.
