Well, Well, Well… What’s Really in Your Water?
Turn on your tap and out comes water—clear, familiar, seemingly simple. But what’s actually in that water depends on where it comes from, how it’s treated, and what it picks up along the way to your faucet.
Whether you’re on a private well or connected to a municipal system, your water quality affects more than just taste. It influences how your skin feels after a shower, whether your dishes come out spotless or spotted, how long your water heater lasts, and yes—what you and your family are drinking.
Understanding the difference between well water and city water is the first step toward making sure what flows through your pipes is as clean and safe as it looks.
Well Water vs. City Water: The Basics
Where Does City Water Come From?
If you’re connected to a municipal water system in the Twin Cities, your water typically originates from either surface water sources (like the Mississippi River) or underground aquifers. Before it reaches your home, it goes through a treatment facility where it’s filtered, disinfected, and tested to meet EPA drinking water standards.
That treatment process often includes adding chlorine or chloramine to kill bacteria, and in many areas, fluoride is also added for dental health. The water is monitored regularly, and your utility is required to provide annual water quality reports.
Where Does Well Water Come From?
Private wells draw water directly from underground aquifers. There’s no treatment plant, no municipal testing, and no required monitoring—the water quality is entirely the homeowner’s responsibility.
Well water skips the chemicals added during municipal treatment, which some homeowners prefer. But it also means any contaminants in the groundwater come straight into your home unless you have filtration in place.
Common Water Issues in Minnesota
Hard water is extremely common throughout Minnesota, whether you’re on a well or city water. The upper Midwest sits on limestone and other mineral-rich geology, which means calcium and magnesium dissolve into groundwater and work their way into municipal supplies.
Well water in Minnesota can also contain iron (causing orange staining), manganese, sulfur (that rotten egg smell), and, in some areas, naturally occurring arsenic or nitrates from agricultural runoff. City water, while treated, may still contain a chlorine taste and odor, sediment from aging pipes, or trace contaminants that meet federal standards but still affect taste and quality.
Why Water Quality Matters
For Your Home
Hard water and mineral buildup take a real toll on your plumbing system and appliances. Scale accumulates inside water heaters, reducing efficiency and shortening lifespan. It clogs showerheads, leaves a film on glass shower doors, and causes water-using appliances to work harder than they should.
Over time, mineral deposits can narrow pipes and reduce water pressure throughout your home. The appliances that suffer most—water heaters, dishwashers, washing machines—are also some of the most expensive to replace.
For Your Family
Water quality affects daily comfort in ways you might not immediately connect. Hard water makes soap and shampoo harder to rinse, leaving skin feeling dry and hair looking dull. Some contaminants affect taste, making tap water unpleasant to drink even when it’s technically safe.
For families with specific health concerns, certain contaminants in well water—like nitrates, arsenic, or bacteria—require attention beyond comfort. And while city water meets federal safety standards, some homeowners prefer additional filtration for peace of mind, especially for drinking water.
Signs Your Water Might Have a Problem
You don’t need a lab test to notice some water quality issues. Watch for:
- Dry skin and dull hair after showering, even with quality products.
- Spots and film on dishes that won’t wipe clean.
- Metallic taste or smell when drinking from the tap.
- Rotten egg odor—a telltale sign of hydrogen sulfide, common in well water.
- Scale buildup on faucets and showerheads.
- Cloudy or discolored water, especially after the water sits unused.
- Rust-colored staining in sinks, tubs, or toilet bowls.
- Soap that won’t lather properly.
These signs don’t necessarily mean your water is unsafe—but they do suggest your water quality could be affecting your home, your comfort, or both.
Why a Professional Water Quality Test Makes Sense
Home test strips can provide some information, but they don’t give you the complete picture. They typically measure only a handful of parameters and can’t detect many of the contaminants that matter most.
A professional water quality test examines your water more comprehensively, identifying exactly what’s present and at what levels. That information matters because the proper treatment depends entirely on what’s really in your water—there’s no one-size-fits-all solution.
For city water, one of our water quality experts performs an in-home test right at your tap. For well water, we collect a sample during a home visit and send it to our Bloomington lab for thorough analysis. Either way, you get clear answers about what’s in your water and what (if anything) you should do about it.
Bonfe’s Water Quality Solutions
Once you know what’s in your water, we can recommend the right treatment. Options include:
Water Softeners remove calcium and magnesium—the minerals responsible for hard water—protecting your plumbing, extending appliance life, and making soap work the way it should.
Reverse Osmosis Systems provide highly filtered drinking water by removing dissolved solids, contaminants, and impurities at the molecular level.
UV Water Treatment uses ultraviolet light to neutralize bacteria and viruses without adding chemicals—particularly valuable for well water systems.
Specialty Filters address specific issues: carbon filters for chlorine taste and odor, iron filters for rust-colored staining, and tannin filters for discoloration common in some well water.
Not every home needs every solution. We’ll help you match the right equipment to your actual water quality and your family’s priorities.
