The Culligan of Red Wing difference

What's Really in Your Water?

Water quality isn’t the same from one neighborhood to the next. Homes throughout Red Wing and the surrounding area can experience everything from hard water and iron staining to naturally occurring contaminants in private wells.

The only way to know what’s in your water is to test it. Professional water testing identifies the minerals, contaminants, and water quality issues affecting your home so you can choose the right solution with confidence.

Culligan offers water testing throughout Red Wing, MN, and surrounding areas, including Pepin and Pierce County, WI, and Goodhue and Wabasha County, MN.

Southeastern Minnesota and western Wisconsin sit on a mix of city water and private wells, and water quality can vary block by block. Some private wells in southeastern Minnesota have been found to contain naturally occurring arsenic, depending on local geology.

In agricultural areas, private wells may be more susceptible to nitrate contamination from fertilizer runoff or nearby septic systems. Many homes served by municipal water in the Red Wing and Lake City area experience hard water caused by naturally occurring calcium and magnesium minerals. A water test tells you which of these you’re actually dealing with, instead of guessing.

We offer a free in-home water test or a full analysis through an EPA-certified lab. Whether you want a quick read on water quality or a detailed breakdown of specific contaminants, Culligan of Red Wing has a testing option built for it.

Our testing identifies everything from hard water and pH levels to bacteria, lead, arsenic, nitrates, and PFAS compounds. Based on the results, we’ll recommend treatment that’s matched to your home’s water quality.

When Should You Get Your Water Tested?

A professional test is the only reliable way to confirm a water problem and find the right fix. Here’s when to schedule one:

You just moved. A new home means new water. Testing confirms it meets safety standards before you settle in.
You’ve never had your water tested. Many homeowners assume their water is fine because it looks and tastes normal. A professional water test establishes a baseline and helps identify issues that can’t be seen or tasted.
You’re on a private well. Wells don’t get monitored the way municipal water does. Agricultural runoff, septic systems, and naturally occurring contaminants can all slip through without regular testing.
Your water’s taste or smell changed. Any shift in taste, odor, or appearance is worth investigating right away.
You’re seeing spots, stains, or scale buildup. Mineral deposits on fixtures, appliances, or dishes usually mean hard water, and testing confirms it.
Your household keeps getting sick. Recurring gastrointestinal issues can point to waterborne pathogens. Testing rules it in or out.

Advanced water testing

If you’ve got a more complex concern, just moved, or own a private well, you may need an advanced test through Culligan’s EPA-certified lab in Illinois. Our EPA-certified laboratory can test for contaminants, including:

Arsenic

A naturally occurring element that leaches into groundwater from local geology. Long-term exposure is linked to cancer and cardiovascular disease.

Lead

Usually comes from old plumbing or lead pipes. Exposure affects neurological development, especially in children.

E. Coli

Signals fecal contamination and the likely presence of harmful pathogens. Exposure can cause gastrointestinal illness.

Nitrates

Common in agricultural areas from fertilizer runoff or septic systems. High nitrate levels are especially risky for infants and pregnant women, and can cause methemoglobinemia (blue baby syndrome).

We also test for dozens of additional contaminants, including copper, radon, PFOS/PFAS, microscopic bacteria, and manganese.

Well water testing

Because private wells aren’t regulated like public water systems, the EPA recommends well owners test their water annually for contaminants such as coliform bacteria and nitrates, and periodically for contaminants like arsenic, based on local conditions.

Frequently asked questions

What is the best way to test your water at home?

The most reliable option is a professional water testing service like Culligan's. Home test kits give you a quick read on specific contaminants, but our service includes analysis through EPA-certified labs for a full picture of your water quality.

How much does professional water testing cost?

Our in-home water test is free, with no obligation to buy anything. If you need an advanced lab analysis for specific contaminants, our team will walk you through the cost for your situation before you commit to anything.

How can you tell if water is safe to drink?

You often can't, at least not by taste, smell, or appearance alone. Contaminants like lead, arsenic, and nitrates are invisible and tasteless. Testing is the only way to know what's actually in your water.

Are home water test kits accurate?

They're useful for a quick screen on common issues like hardness or chlorine, but they have limits. For contaminants like lead, arsenic, or bacteria, lab-based testing gives you a far more reliable result.

How do you know if there is lead in your drinking water?

There's no reliable way to detect lead without testing. It has no taste, smell, or color. Homes built before 1986 carry a higher risk due to old plumbing and lead solder, which makes testing especially important if your home falls in that range.

Do water filters remove lead?

Not all of them. Standard carbon filters may reduce some lead, but a filter needs to be certified specifically for lead removal, like an NSF/ANSI 53-certified filter or a reverse osmosis system, to reliably bring levels down.
