How Stevens Point Compares
Stevens Point's water is 27% harder than the national average of 138 PPM. It ranks #392 out of 1000 cities in our database (harder than 61% of US cities we track). Within Wisconsin, it ranks #10 of 17 cities (17% below the state average of 210 PPM). Among smaller cities, Stevens Point ranks #97 of 288 for hardness. At this hardness level, water heaters run an estimated 32% less efficiently due to scale insulation, and major water-using appliances typically last 2 years less than the national average lifespan.
What Stevens Point's Water Means for Your Home
Hardness: 175 PPM - Treatment Recommended
Stevens Point's water is solidly hard at 175 PPM (10.2 GPG). That's enough to notice every day: gradual scale on fixtures, spots on dishes, soap that doesn't lather the way it should. That's 17% softer than the Wisconsin average. Homeowners who install a water softener or salt-free conditioner notice the difference fast: better lathering, cleaner dishes, and appliances that last longer. That adds up. Hard water at 175 PPM increases household costs through scale-coated water heaters that use more energy, extra soap and detergent, and appliances that wear out faster. Most Stevens Point homeowners don't realize it until the plumber shows up.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Stevens Point's water has TTHMs at 22.8 ppb and HAA5 at 6.19 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
Even though Stevens Point draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 22.8 ppb and HAA5 at 6.19 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines.
Chromium-6 is naturally present in Stevens Point's aquifer geology at 0.175 ppb — 8.8x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
How Hard Water Affects Your Home
At 175 PPM, untreated hard water has measurable effects on household costs and appliance life:
- Water heater inefficiency: Scale insulation forces the heater to work harder (DOE estimates up to 22% more energy for heavily scaled units)
- Soap and detergent: Hard water reduces lathering, requiring significantly more product
- Appliance replacement: Water heaters, dishwashers, and washing machines fail 2-4 years earlier due to scale buildup
- Plumbing maintenance: Scale buildup in pipes reduces flow and requires more frequent service
Note: Impact varies by household size, water usage, and local energy costs. A home water test provides the most accurate assessment for your specific situation.

About Stevens Point's Water Supply
Water Utility: Stevens Point Water Department
Water Source: Local wells (Groundwater)
Population Served: 26,717
Hardness: 175 PPM (10.2 grains per gallon)
Stevens Point draws its drinking water from groundwater sources — Local wells. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why hardness is elevated here. Calcium and magnesium dissolve into the water as it moves through limestone and dolomite. The system serves 27,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Stevens Point Water Department's Consumer Confidence Report (CCR) or test your own tap.

Water Softener Sizing for Stevens Point
At 175 PPM (10.2 GPG), here is how to size a softener for your Stevens Point home. Multiply hardness in GPG (10.2) by daily water usage (roughly 50 gallons per person). A family of four uses about 200 gallons/day: 10.2 GPG × 200 gal = 2040 grains/day. Over a 7-day regeneration cycle, that is 14,280 grains - a 32,000-grain softener is the right fit for most Stevens Point households.
