Portage, MI City Water

What's in Your Portage Tap Water?

Portage runs its own water system, drawing from 19 wells inside the city and treating the water to meet every federal and state standard. The city operates its own arsenic removal plant, and its service line inventory turned up no lead pipes at all. It doesn't soften the water. Here's what's in Portage's water, and what you can do about it.

The source

Where Portage's Water Comes From

Portage pumps groundwater from 19 wells scattered across the city, drawing on the Kalamazoo-Portage and Schoolcraft aquifers. The city is fully independent: it does not buy water from Kalamazoo or anyone else, and it treats everything it delivers at its own facilities.

Treatment covers chlorine for disinfection, fluoride for dental health, and phosphate for corrosion control and to hold iron in solution. The Garden Lane facility removes arsenic from the groundwater before it goes out to the system, which is a meaningful step and not one every Michigan city has to take.

The state's source water assessment rated the susceptibility of Portage's well sites as high, which is why the city maintains a wellhead protection program. Portage reports no contaminant level violations in 2025, and says the water is tested daily. Treatment doesn't include softening, so your water reaches the house as hard as it was in the aquifer.

Water Hardness

Is Portage's Water Hard?

Yes. Groundwater across Kalamazoo County carries a heavy mineral load, and Portage's is no exception.

The city doesn't publish a hardness figure in its annual water quality report, which is common for Michigan utilities since the state doesn't ask for one. Regional groundwater estimates for the county put it somewhere from the mid teens into the low 20s grains per gallon, well into the "very hard" range, but none of those is a measurement of Portage's finished water. Neighboring Kalamazoo, drawing from similar ground, has been described by its own staff as averaging around 20 grains.

What is certain is that Portage doesn't soften. That mineral load is what leaves spots on your glasses, scale on your faucets and showerheads, and a film that keeps soap from lathering. Over time it dries out skin and hair and wears on water heaters and appliances. Since no published number exists for Portage, a free water test at your address is the only way to find out what you're working with.

Beyond hardness

What Else Is in Portage's Water?

Portage reports that its water meets or exceeds all federal and state quality standards, with no contaminant level violations in 2025. A few things are still worth understanding:

19city wells, plus a dedicated arsenic removal facility

Arsenic

Portage is one of the Michigan cities that has to treat for it. The Garden Lane facility removes arsenic before the water enters the distribution system, and 2025 results came in at 3 parts per billion against a limit of 10. That's compliant, and it is also the reason the treatment plant exists.

Reverse osmosis reduces arsenic further at the tap if you want another layer.

Iron and manganese

The city adds phosphate to keep iron dissolved rather than staining fixtures, which tells you there's enough in the raw groundwater to need it. Portage doesn't publish iron or manganese levels.

A whole-home filter handles staining and metallic taste where the water enters your house.

Sodium

Portage measured between 11 and 75 parts per million in 2025. There's no federal limit, but the EPA advises 20 ppm for people on sodium-restricted diets, so the high end matters if your doctor has you watching it.

Reverse osmosis reduces sodium at the drinking tap.

Chlorine and disinfection byproducts

Chlorine keeps water safe as it travels through the pipes, but it affects taste and smell, and it forms trace byproducts. Total trihalomethanes measured 42 parts per billion in 2025 against a limit of 80.

A carbon or reverse osmosis filter reduces both at your tap.

PFAS

Michigan adopted some of the strictest PFAS limits in the country in 2020. Portage's 2025 testing found PFBS at 7.7 parts per trillion against a limit of 420 and PFHxS at 5.0 against a limit of 51, with the other five regulated compounds non-detect. The city has a separate PFAS investigation underway at its former landfill and firefighter training site, and testing of the municipal supply has not exceeded health advisory levels.

If you want added assurance, we offer a third-party PFAS test and treatment rated to reduce PFAS.

Lead from home plumbing

Good news here: Portage inventoried all 15,000 service lines in its system and found no lead ones. Older homes can still pick up trace lead from interior pipes and fixtures, and the city's 2023 testing put the 90th percentile at 2 parts per billion.

A reverse osmosis system at the kitchen sink covers that at the point you drink from.

Questions

Frequently Asked Questions

Do I need a water treatment system if I'm on Portage city water?
Most Portage homes get something out of it. The city delivers safe water that meets every federal and state standard, but it arrives very hard, carries iron, and holds trace arsenic and sodium along with the chlorine used to keep it safe in the pipes. A softener handles the hardness, and a drinking water system handles the rest at the tap. A free water test shows you exactly what your home is working with so you can decide.
Is Portage tap water safe to drink?
Yes. The city reports that Portage water meets or exceeds all federal and state quality standards, with no contaminant level violations in 2025, and says the water is tested daily. Treatment at home is about hardness, taste, and an added layer of filtration at the tap, not because the city water is unsafe.
How hard is Portage water?
Hard enough that most homes notice. Portage doesn't publish a hardness number in its annual report, and no measurement of the city's finished water is publicly available. Groundwater across Kalamazoo County generally tests from the mid teens into the low 20s grains per gallon, and neighboring Kalamazoo's own staff have described their water as averaging around 20 grains. Portage doesn't soften, so a free test at your address is the only way to get your real number.
Does Portage water have arsenic?
Portage's groundwater does carry arsenic, which is why the city operates a dedicated removal facility at Garden Lane that treats the water before it enters the distribution system. The 2025 result was 3 parts per billion against a federal limit of 10. If you want the level lower still, a reverse osmosis system at the kitchen sink reduces arsenic at the tap you drink from.
Does Portage water have PFAS?
Portage's 2025 testing found PFBS at 7.7 parts per trillion against a Michigan limit of 420, and PFHxS at 5.0 against a limit of 51. The other five regulated compounds were non-detect. The city has a PFAS investigation underway at its former landfill and firefighter training site, and testing of the municipal supply has not exceeded health advisory levels. If you'd like added assurance for your own home, we offer a third-party PFAS test and treatment rated to reduce PFAS.
How much does a water treatment system cost?
It depends on your water and which system fits best. We provide free in-home water tests and lay out options at different price points, so you can choose what works for your home and budget.
