The Top 5 Most Common Contaminants Found in Water

Clean water is essential for everyday life, from cooking and bathing to drinking and cleaning. But not all water is as pure as it seems. Whether you're using well water in rural Minnesota or city water in a suburban neighborhood, your water may contain invisible contaminants that pose serious risks. At Finken, we’re dedicated to helping homeowners and businesses across Minnesota and western Wisconsin identify and eliminate these threats.

Here are the five most common water contaminants and how to safeguard against them.

1. Lead

What It Is:

A toxic metal often found in older plumbing systems and service lines.

Health Risks:

• Developmental delays in children
• High blood pressure
• Kidney damage
• Neurological issues

How Finken Helps:

With reverse osmosis systems and whole-home filtration, we help remove lead from drinking water and prevent long-term exposure.

2. Nitrates

What They Are:

Compounds commonly found in groundwater, especially in agricultural regions due to fertilizer runoff.

Health Risks:

• “Blue baby syndrome” in infants
• Breathing issues
• Increased cancer risk with prolonged exposure

Finken’s Solution:

We offer advanced filtration systems specifically designed to reduce nitrate levels, protecting your family’s health.

3. Chlorine and Chloramine

What They Are:

Disinfectants added to municipal water to kill bacteria but they can also create harmful byproducts.

Health Risks:

• Skin and eye irritation
• Respiratory issues
• Increased risk of bladder cancer with long-term exposure

Why It Matters:

While chlorination is necessary, residual chemicals can affect taste, smell, and health. Our whole home systems and carbon filters help eliminate these concerns.

4. Bacteria and Microorganisms (e.g., E. coli, Giardia)

Where They Come From:

Found in untreated or poorly treated water, especially from wells or during flooding.

Health Risks:

• Severe gastrointestinal illness
• Vomiting and diarrhea
• Long-term digestive complications

Our Approach:

Finken’s water testing services can detect bacteria, and our UV purification and filtration systems destroy or remove pathogens effectively.

5. Hard Water Minerals (Calcium & Magnesium)

What They Are:

Naturally occurring minerals that aren’t hazardous but can cause other problems.

Side Effects:

• Dry skin and hair
• Scale buildup on appliances
• Reduced soap effectiveness
• Shorter lifespan for water-using appliances

Finken’s Fix:

Our water softeners eliminate these minerals, improving water quality and protecting your plumbing system.
