How often should well water be tested for radon?

Answer: For a private well, testing for radionuclides, including radon, about every three years is a reasonable guideline. In North Carolina, homeowners should also test the home’s air for radon first; if indoor radon is elevated, testing the well water can help determine whether the water is contributing to the indoor level.

Answer: Same as the air. At least every 2 years
