Test. Radon & Well Water.

The vast majority of radon in indoor air comes from the soil gases beneath the home's foundation. However, homes with groundwater supplies can have elevated radon levels in their water.

Radon in well water poses slight risks.

If your home has a well, the radon in your water supply can pose risks from inhalation and ingestion.  According to the EPA, your risk of lung cancer from inhaling radon in the air is significantly higher than your risk of stomach cancer from drinking water containing radon.

Radon readily degasses from water and can cause an additional amount of radon to enter the air beyond that which comes from soil gases. It can be brought into your home via the water supply when you shower, wash dishes, etc.  Generally, 10,000 pCi/L in water adds 1 pCi/L of radon to indoor air.

If you have high indoor radon levels, test your well water.

If you've tested your home's indoor air and the radon levels are elevated, you may want to test your well water. This second test will to determine which source (soil or well water) is the greater contributor, and which method you should pursue to reduce indoor radon levels.

When you purchase a home, your well-water expert may test the water for radon in addition to testing for other water contaminants.  If radon is not within the scope of the water testing, we can test it specifically for radon.

We use a third-party laboratory to analyze the water sample that we collect from your home.  Using an independent third party eliminates any bias in the testing process, which is particularly important in a real estate transaction.
