Understanding Radon in Water in Georgia: A Complete Guide - Image 1

Radon is commonly known as a threat to indoor air quality—but did you know it can also enter your home through your water supply? If you rely on a private well in Georgia, radon in water may be an unseen risk. This guide from Georgia Radon Defense helps you understand the presence of radon in water, how it affects your health, and what you can do to protect your home and family.

The Significance of Radon in Georgia’s Water Supply

In Georgia, certain geological conditions make radon in water more prevalent, particularly for homeowners using private well systems. While public water supplies are regularly tested and treated, private wells are not, which means radon can go undetected unless you test for it.

Understanding Radon: A Naturally Occurring Element

Radon is a colorless, odorless radioactive gas that forms naturally when uranium in soil and rock breaks down. It can enter your home through air and water, with groundwater being a key pathway—especially in areas with granite bedrock, like much of Georgia.

Why Radon Is a Concern in Georgia

Regions across Georgia, including Athens, Winder, and Gainesville, sit on granite-rich soil that releases radon into groundwater. Homes using private wells in these areas may unknowingly have elevated radon levels in their water supply.

Sources of Radon in Water: Exploring the Origins

Groundwater: How Geology Influences Radon Levels

Radon dissolves into groundwater as it moves through uranium-bearing rocks. Because groundwater remains in contact with these rocks for long periods, radon concentrations can be higher in well water than in surface water sources.

The Impact of Well and Surface Water on Radon Concentrations

Private wells drawing from deep underground aquifers are most likely to have elevated radon levels. Surface water, such as lakes or rivers, tends to have lower radon due to natural aeration, which allows radon to escape before reaching your home.

Health Risks: The Dangers of Radon Exposure

Radon and Its Connection to Lung Cancer

Radon exposure is the second leading cause of lung cancer in the U.S. While the primary risk comes from inhaling radon gas, radon in water contributes to indoor air radon when it’s released during activities like showering or washing dishes.

Other Health Risks Associated with Radon in Drinking Water

Drinking water with radon can slightly increase the risk of stomach cancer, but the greater concern remains inhaled radon, which can accumulate in your home and increase lung cancer risk over time.

Testing for Radon in Water: Your Essential Guide

How to Conduct a Radon Water Test at Home

You can use a home radon water test kit, which includes detailed instructions for sample collection. The sample must be sent to a certified lab quickly for accurate results.

Choosing Professional Testing Services in Georgia

Georgia Radon Defense offers professional radon water testing, ensuring accurate results and expert recommendations for next steps. We handle everything from sampling to interpreting results and advising on mitigation.

Interpreting Test Results: What Do They Mean?

Below 4,000 pCi/L: Low risk, but continue monitoring if airborne radon is detected.
Above 4,000 pCi/L: Action is recommended. Consider mitigation for both water and indoor air.

Mitigation Strategies for Radon in Water Supplies

Effective Removal Techniques for Homeowners

Two common solutions for radon in water are:

Aeration Systems – Mix air with water to release radon, then safely vent the gas outdoors.
Granular Activated Carbon (GAC) Filters – Trap radon particles, ideal for lower radon levels.

Long-Term Solutions for Radon Reduction

Aeration systems are highly effective and suitable for higher radon concentrations. GAC filters offer a simpler option but require routine maintenance.

DIY vs. Professional Mitigation: Pros and Cons

DIY: Lower cost but may not offer reliable results.
Professional: Expert installation, higher efficiency, and long-term peace of mind.

Georgia Radon Defense provides proven, professional radon mitigation solutions tailored to Georgia homes.

Frequently Asked Questions About Radon in Water and Health

Can radon in water make you sick right away?

No, radon exposure does not cause immediate illness. It’s a long-term risk, with serious health issues like lung cancer developing after years of inhalation or ingestion. Most people won’t notice symptoms early on.

What are possible symptoms of radon-related health issues?

Symptoms typically appear after prolonged exposure and may include:

A persistent cough
Chest discomfort or pain
Shortness of breath or wheezing
Unexplained weight loss
In advanced stages, coughing up blood

How can I test my water for radon?

You can use a certified radon water test kit or schedule professional testing with Georgia Radon Defense. We ensure accurate sampling and provide clear recommendations based on your results.

Is radon-related health damage reversible?

Unfortunately, no. Once radon enters the body and damages lung tissue, the effects are permanent. This is why early detection and mitigation are so important.

Does private well water have more radon than city water?

Yes. Private wells, which draw from underground sources, are more likely to contain radon. In contrast, municipal water systems are regularly tested and treated, making them less susceptible to radon contamination.

Protect Your Home: Test for Radon in Water Today

If you use a private well, now is the time to test your water for radon. Georgia Radon Defense offers accurate testing and expert solutions to help you reduce radon levels and protect your family.
