Anomalously high levels of uranium and
210 Pb have been detected in untreated domestic groundwater wells near Simpsonville/Fountain Inn, South Carolina. Nine wells were sampled from the affected area and analyzed for total uranium,234,235,238 U,226,228 Ra,222 Rn, and210 Pb as well other water quality parameters. These data augment other uranium concentration measurements and limited226,228 Ra and222 Rn concentration measurements collected on private and public wells by the South Carolina Department of Health and Environmental Control. The observed radionuclide data were compared to maximum levels published in several national surveys from the past 30 years. The total uranium concentration in the groundwater ranged from 44.3 to 5,570 µg L-1 , with one well having the second highest published concentration in the U.S. The234 U/238 U activity ratio ranged from 1.1 to 2.5.226 Ra concentrations ranged from less than the minimum detectable concentration (< MDC) to 1,154 mBq L-1 while the228 Ra concentration ranged from < MDC to 532.8 mBq L and the Rn levels ranged from 62 to 1,510 Bq L-1 . The210 Pb concentrations ranged from < MDC to 844 mBq L-1 . [ABSTRACT FROM AUTHOR]- Published
