The Realities of Water in Cottage Grove, MN

Cottage Grove’s water supply—a mix of municipal and private wells—often contains naturally occurring minerals and iron, along with added disinfectants like chlorine. These contribute to hard water, staining, strange tastes, and appliance damage.

Here are the most common water quality issues we see in Cottage Grove homes, and how A.J. Alberts can help:

Hard Water & Mineral Buildup

Hard water is the most frequent complaint among Cottage Grove homeowners. Water hardness comes from calcium and magnesium, which cause scale buildup in pipes and water heaters, cloudy spots on glassware, and dry, itchy skin.

A.J. Alberts can fix this by installing a professional water softener, which removes calcium and magnesium to improve skin feel, extend appliance life, and save you money over time.

Iron in the Water

High iron levels are common in both municipal and private well systems around Cottage Grove. Iron leaves behind reddish-orange stains, a metallic taste in drinking water, clogged filters, and buildup in pipes and appliances.

We recommend a whole-house iron filtration system that’s specifically designed to handle Minnesota’s iron-heavy water. These filters can remove both ferrous (clear water iron) and ferric (red water iron), preventing staining and improving water clarity and taste.

Chlorine Taste and Odor

While the City of Cottage Grove treats water to meet EPA safety standards, chlorine is commonly added as a disinfectant. That can lead to bad-tasting water, unpleasant odors, dry skin and hair, and increased wear on plumbing fixtures.

A.J. Alberts can combat this with a whole-house carbon filtration system. Carbon filters naturally remove chlorine, chloramines, pesticides, and other organic chemicals, leaving you with clean, odor-free water from every faucet.

Contaminants in Drinking Water

Some Cottage Grove residents are concerned about additional contaminants like lead, nitrates, arsenic, and trace pharmaceuticals, which may not be fully removed by municipal treatment.

We can combat this by installing a reverse osmosis system. Reverse osmosis (RO) is one of the most effective methods of purifying drinking water. Our multi-stage RO units remove up to 99% of contaminants, delivering clean, safe, bottle-quality water right from your kitchen tap.

Frequently Asked Questions in Cottage Grove, MN

What’s causing the orange stains in my sinks and toilets?

This is usually due to high iron levels in your water. A properly sized iron filtration system can eliminate this issue completely.

Is Cottage Grove water hard?

Yes. Water in Cottage Grove typically tests between 12–18 grains per gallon (gpg), which is considered hard to very hard. A water softener is highly recommended.

How long does installation take?

Most water softeners, filters, and RO systems can be installed in just a few hours, depending on your plumbing layout.

Yes! We offer affordable financing options with flexible terms to help you invest in your water quality without stress.
