Radionuclide contamination of drinking water is a significant, emerging issue. Until now, manmade radioactivity in drinking water has not been a major problem. Natural sources have been the primary cause of contamination. However, the potential for contamination exists throughout the country as releases from medical facilities or nuclear power plants may wind up in drinking water. Because of their potential health effects and widespread occurrence, natural radionuclides—including radon, radium, and uranium—cause much concern.
