Water Treatment in Minneapolis, MN

Minneapolis treats Mississippi River water, lime-softens it and disinfects with chlorine, so it reaches your tap already softened — a home softener is usually redundant. What the plant leaves behind is chlorination byproducts and chromium-6, which reverse osmosis and whole-home carbon reduce. Edina Plumbing quotes only what your water needs, upfront and with no pressure.

Your Minneapolis water

Softened Mississippi River Water

Surface water, softened and chlorinated. Unlike its well-water suburbs, Minneapolis treats Mississippi River surface water, lime-softens it and disinfects with chlorine. It reaches your tap already softened, so a home softener is usually redundant here.
So we won’t sell you a softener. Because the city softens the water centrally, a home softener would be largely redundant, and we won’t pitch one you don’t need. The honest question in Minneapolis is drinking-water quality — the byproducts that come with treating river water — not hardness.
The water your neighbors drink, too. Minneapolis wholesales its finished water to several suburbs, including Edina’s Morningside neighborhood and part of Bloomington — so this same softened river water reaches well beyond the city line. Every address here is on municipal water, not a private well.

What softening doesn’t remove

River Byproducts & Chromium-6 — Where RO Comes In

Disinfection byproducts run high. Treating river water with chlorine produces disinfection byproducts. EWG flags haloacetic acids at about 340× and trihalomethanes at about 112× its health guidelines in Minneapolis — the family reduced by whole-home carbon and reverse osmosis. These are above EWG’s health guidelines, not legal limits.
Chromium-6 and nitrate. EWG also lists chromium-6 and nitrate above its health guidelines here. An under-sink reverse-osmosis system reduces both, along with byproducts and PFAS, at the drinking tap — giving residents the choice to minimize exposure.

What actually helps in Minneapolis

Reverse Osmosis & Whole-Home Carbon

Reverse osmosis for the river byproducts. An under-sink reverse-osmosis system is the main recommendation here — it reduces the chlorination byproducts, chromium-6 and nitrate that come with treating and chlorinating river water.
Whole-home carbon for chlorine taste. Whole-home carbon filtration takes the chlorine taste and odor out at every tap and cuts disinfection byproducts house-wide — the honest pairing for softened river water.
Honest pricing, no softener. RO and whole-home carbon at an honest, upfront price — the same NSF-certified equipment big dealers push in high-pressure in-home demos, without the markup or a softener you don’t need. If your water is fine as-is, we say so.

What's Actually in Minneapolis's Water

Even after Minneapolis softens it, the water still carries PFAS and other contaminants the EWG Tap Water Database flags above its health guidelines. Here's what's in it, what each is linked to, and what removes it at home.

Water Treatment in Minneapolis — Common Questions

Do I need a water softener in Minneapolis?

Usually not. Minneapolis treats Mississippi River water and lime-softens it centrally, so it reaches your tap already softened — a home softener is typically redundant. We would rather point you to what actually helps here: drinking-water treatment for the chlorination byproducts that come with treating river water, which softening does not remove.

Where does Minneapolis water come from?

From the Mississippi River. Minneapolis draws surface water, softens it with lime and disinfects it with chlorine at its treatment plant, then distributes it across the city and wholesales it to several suburbs. Because it is treated river water rather than groundwater, its profile — softened, but higher in chlorination byproducts — is different from the well-water suburbs nearby.

What does Minneapolis use to disinfect the water?

Minneapolis disinfects its water with chlorine. Chlorine treatment of river water produces disinfection byproducts such as trihalomethanes and haloacetic acids, which EWG lists above its stricter health guidelines here. Whole-home carbon filtration and reverse osmosis reduce both the chlorine taste and those byproducts. The water is in full federal compliance; this is about the choice to reduce them at home.

If the water is softened, why treat it at all?

Because softening removes hardness minerals, not chlorination byproducts, chromium-6, nitrate or PFAS. EWG lists byproducts especially high in Minneapolis because the source is treated river water. A whole-home carbon filter and an under-sink reverse-osmosis system reduce them at home. The water meets all federal limits; this is about giving you the choice to reduce exposure at the drinking tap.
