High Radium-226 Concentrations in Public Water Supplies

Abstract

To identify population groups in the United States having relatively high chronic intakes of radium from drinking water, samples of approximately 900 public ground water supplies serving 3.8 million people in 20 States were analyzed in 1966-67. After the National Center for Radiological Health, Public Health Service, had arranged for the water sampling with the health departments of the 20 States, personnel of these departments or of community water departments collected 1-liter samples of the selected water supplies and mailed them to the laboratory performing the radium analyses. The response to the request for water samples was more than 94 percent. Forty-one water supplies, serving 144,000 people in 10 States, were found to have 3 or more pCi (picocuries) of radium-226 per liter. Four supplies, serving 3,000 people, contained 10 or more pCi per liter. The highest concentration observed was 24.1 pCi per liter, in a supply serving 360 people.
