【 摘 要 】

Statistical analyses were performed on groundwater monitoring data obtained for gross alpha, radium 226, and 228 from the SRS Sanitary Landfill (SLF). Several inference tests were performed using the prescribed statistical methods of the Resource Conservation and Recovery Act Part B Permit regulations (US EPA 1992). Test results show that the LFW 29R, LFW 57B and LFW 62B wells have significantly elevated concentrations of all three radiological constituents above background. However, isotopic ratios of Ra228 to Ra226 are consistent with naturally occurring concentrations of each. In addition, corresponding pH data for these same three wells suggests that acidic conditions may have effected a mobilization of naturally occurring radium from the soils associated with the SLF. In fact, there is a statistically significant and negative correlation between gross alpha, Ra226, and Ra228 measurements vs pH.
