Compared to radon entering the home through soil, radon entering the home through tap water will in most cases be a small source of radon in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may also cause increased risk of stomach cancer. If you are concerned about radon in your home, test the air in your home.
Testing is inexpensive and easy.
Radon testing was not required by the regulatory agencies for the City of Salina Water System in 1999. Radon has not been detected on previous tests. Certified laboratories analyze water samples on a daily basis at various points in the treatment process. Samples are also obtained on a regular basis to insure the water quality is maintained throughout the distribution system. Approximately 80,000 samples are taken and analyzed each year to provide this quality assurance.
