The U.S. Environment Protection Agency has proposed a drinking water standard for {sup 222}Rn in public water supplies. When promulgated, operators of public water supplies will be required to determine water {sup 222}Rn concentrations. Most likely, water samples will be collected and mailed to laboratories for analyses. Additionally it is probable that homeowners will test private well water in a similar manner by collecting water samples and mailing them to a laboratory for {sup 222}Rn analyses. In anticipation of these actions, this study was conducted to evaluate two methods of water sample collection and to evaluate the potential losses of {sup 222}Rn from water samples mailed to a laboratory. Thirdly, temporal variations in {sup 222}Rn concentrations in several groundwater supplies in North Carolina were examined. Water supplies at four sites in eastern North Carolina and five sites in western North Carolina were sampled over a 7-mo period beginning in the fall of 1993 and continuing through the spring of 1994. Temporal variations in water {sup 222}Rn concentrations was the striking influence that inconstant water usage and inadequate well purging prior to sample collection had on {sup 222}Rn loss from the water. 5 refs., 10 figs., 4 tabs.
