Radon: What Homebuyers Need to Know Before Closing the Deal

April 16, 2025      

When purchasing a home, many buyers overlook the potential risks of radon in water, yet it’s a crucial consideration. At The Radon Guys, we’re here to guide you through the importance of understanding radon and how to ensure your new home remains safe.

What Is Radon in Water?

Radon is a naturally occurring radioactive gas that can enter a home's water supply, particularly in properties with private wells or located in radon-prone areas. While radon in water doesn’t get as much attention as radon in the air, it still poses health risks, especially when released into the air during everyday activities like drinking, cooking, or showering.

Why Should Homebuyers Be Concerned?

Exposure to radon in the air is a well-known cause of lung cancer, but the long-term effects of radon in water are less understood. Even so, the inhalation of radon during common household activities remains a potential concern.

How to Test for Radon in Water

If you’re in the process of buying a home, especially one with a private well, testing for radon should be a priority. Radon levels in water are measured in picocuries per liter (pCi/L), with the EPA’s threshold set at 4,000 pCi/L. Testing is essential to evaluate the risk to your health.

What to Do if Radon Is Detected

If radon is found in the water, don’t panic. Several reliable radon mitigation methods can help. The most common solutions include:

Aeration Systems: These systems release radon from the water by bubbling air through it.

Granular Activated Carbon (GAC) Filters: These filters capture and remove radon from the water.

Both solutions are highly effective in reducing radon levels to safe limits.

Should You Consider Walking Away?

Discovering radon in the water doesn’t mean you have to abandon your dream home. Mitigation systems can be installed to address the issue, but it’s important to factor in the cost of these systems when making your decision.
