How Burnsville Compares
Burnsville's water is 85% harder than the national average of 138 PPM. It ranks #165 out of 1000 cities in our database (harder than 84% of US cities we track). Within Minnesota, it ranks #6 of 16 cities (18% above the state average of 216 PPM). Among cities (50k-100k), Burnsville ranks #52 of 258 for hardness. At this hardness level, water heaters run an estimated 47% less efficiently due to scale insulation, and major water-using appliances typically last 4 years less than the national average lifespan.
What Burnsville's Water Means for Your Home
Hardness: 255 PPM - Treatment Recommended
Burnsville has some extremely hard water. At 255 PPM (14.9 grains per gallon), your tap is loaded with mineral content carried in from the watershed geology. Here's the thing: it's perfectly safe to drink. The minerals won't hurt you. But they will hurt your wallet. That adds up. Hard water at 255 PPM increases household costs through scale-coated water heaters that use more energy, extra soap and detergent, and appliances that wear out faster. Most Burnsville homeowners don't realize it until the plumber shows up. That's 18% harder than the Minnesota average.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Burnsville's water has TTHMs at 23.5 ppb and HAA5 at 5.63 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
Burnsville's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 23.5 ppb (29% of the legal limit, but 157x the EWG guideline) and HAA5 at 5.63 ppb (9% of the legal limit, but 56x the EWG guideline). These are within legal limits, but the EWG sets much tighter thresholds based on cancer-risk research. A whole-house activated carbon filter reduces both chlorine and byproducts.
Chromium-6 was detected at 0.068 ppb, which is 3.4x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
How Hard Water Affects Your Home
At 255 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.

Population Served: 61,747
Hardness: 255 PPM (14.9 grains per gallon)
Burnsville's drinking water comes from surface sources — Local wells & Minnesota River. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. Despite the treatment process, mineral hardness from the watershed carries through. The system serves 62,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Burnsville Water's Consumer Confidence Report (CCR) or test your own tap.

Water Softener Sizing for Burnsville
At 255 PPM (14.9 GPG), here is how to size a softener for your Burnsville home. Multiply hardness in GPG (14.9) by daily water usage (roughly 50 gallons per person). A family of four uses about 200 gallons/day: 14.9 GPG × 200 gal = 2980 grains/day. Over a 7-day regeneration cycle, that is 20,860 grains - a 32,000-grain softener is the right fit for most Burnsville households.
