The Link Between Radon in Water and Cancer: What Research Says

July 31, 2025      

When people think of radon, they often picture a silent, invisible gas seeping into basements. But radon doesn’t just enter your home through the air—it can also be present in your water supply, especially if your home uses a private well.

So, what’s the risk?

According to the Environmental Protection Agency (EPA) and numerous health studies, long-term exposure to radon in water has been linked to stomach cancer and may contribute to lung cancer when radon gas is released into the air during activities like showering, cooking, and washing dishes.

While the risk from radon in water is generally lower than that from radon in air, it's not something to ignore—especially if you're relying on groundwater. Ingesting radon over time can allow radioactive particles to build up in the lining of the stomach, potentially damaging cells and increasing cancer risk.

The good news? Radon in water is detectable and treatable.
