What Homeowners Need to Know

Water Quality in Cedarburg, Wisconsin

If you live in Cedarburg, Wisconsin, understanding your home’s water quality is essential for protecting your health, plumbing, and appliances. Whether your water comes from the City of Cedarburg municipal system or a private well, the region is known for having extremely hard water and naturally occurring contaminants such as iron, arsenic, and manganese.

Cedarburg’s water is sourced from deep underground aquifers, delivering mineral-rich groundwater to both public and private systems. While this water meets basic safety standards, many local homeowners face common issues such as:

  • Limescale and hard water deposits

  • Rust stains and iron in the water

  • Unpleasant odors or metallic taste

  • Contaminants like arsenic, nitrates, and PFAS

Solutions to Common Issues

Choosing the Right Water Treatment for Your Home

Not all water is the same and neither are the solutions. Whether your water comes from a city supply or a private well, it can carry different minerals, chemicals, or contaminants that affect your home and health.

That’s why it’s important to look at all four key options:

Water softeners for hard water problems

Whole house filters for chlorine, odors, and sediment

Reverse osmosis systems for safe, great-tasting drinking water

Iron filters for rust stains and rotten egg smells

Your water source and the issues it brings will help determine which system (or combination) is right for you.

Water Softener

Hard water has minerals like calcium and magnesium that cause issues around your home. A water softener removes them for cleaner, better-feeling water.

Hard water can:

  • Leave spots on dishes
  • Make soap and shampoo less effective
  • Cause buildup on faucets and showerheads
  • Shorten the life of appliances
  • Dry out your skin and hair

A water softener:

  • Removes hard minerals
  • Helps soap work better
  • Protects appliances
  • Makes water feel soft on skin

If you see signs of hard water, a softener is a smart fix.

Drinking Water System

Even if your tap water looks clean, it can still contain dissolved solids, chemicals, or contaminants you don’t want to drink. Reverse osmosis gives you highly purified water, right at the tap.

Unfiltered drinking water can have:

  • Chlorine, lead, or other chemicals
  • Nitrates, fluoride, or heavy metals
  • Cloudiness or bad taste
  • Pollutants from old pipes or plumbing

A reverse osmosis system:

  • Removes up to 99% of contaminants
  • Improves taste, clarity, and odor
  • Gives you bottled-quality water at home
  • Fits neatly under the kitchen sink

If you want cleaner, safer, better-tasting drinking water, RO is the gold standard.

Drinking Water Systems

Need an Iron Filter

If your water leaves orange stains or smells like metal or rotten eggs, iron could be the problem. An iron filter removes it before it damages your home.

Iron in water can:

  • Leave orange or brown stains in sinks, tubs, and toilets
  • Make water smell metallic or like rotten eggs (if sulfur is present)
  • Clog plumbing and damage appliances
  • Affect the taste of your water and food
  • Turn laundry yellow or dingy

An iron filter:

  • Removes iron, manganese, and sulfur odors
  • Protects pipes, water heaters, and fixtures
  • Stops staining and metallic smells
  • Keeps water clear and fresh

If your water looks rusty or smells off, an iron filter can make a big difference.

Whole House Water Filter

Tap water can carry things you don’t want—like chlorine, sediment, rust, or even odd tastes and smells. A whole house filter cleans the water before it reaches any faucet.

Unfiltered water can:

  • Smell or taste bad
  • Leave stains in sinks, tubs, and toilets
  • Carry chlorine or other chemicals
  • Irritate skin or worsen allergies
  • Let sediment build up in pipes and appliances 

A whole house filter:

  • Removes chlorine, rust, dirt, and odors
  • Improves water taste and smell
  • Protects pipes, fixtures, and appliances
  • Provides clean water from every tap
