Evaluation of isotope migration - land burial. Water chemistry at commercially operated low-level radioactive waste disposal sites. Status report, October 1979-September 1980. [Maxey Flats, KY and Barnwell, SC]
A field and laboratory program was initiated to study the existing commercial low-level radioactive waste disposal sites. This investigation will provide source term data for radionuclides and other solutes in trench waters at the sites and will describe the physical, chemical, and biological properties of the geochemical system that control the movement of radionuclides. In the past year, the disposal sites at Maxey Flats, Kentucky, and Barnwell, South Carolina, were sampled, Maxey Flats for the fourth time, Barnwell for the second. Results of trench water inorganic, organic, and radiochemical analyses are similar to those reported for previous samplings. No overall systematic changes in any disposal trenches were observed during the relatively brief sampling interval. However, changes in some radionuclide and inorganic components were observed in several trenches. Tritium was the most abundant of the radionuclides and was found in all the trench waters. Analyses of water collected from a series of experimental interceptor trenches at Maxey Flats showed them to have a chemical composition intermediate between disposal trench water and local groundwater. Preliminary results of batch sorption tests using site-specific materials from the Barnwell disposal site are reported. Tritium content as a function of depth has been determined in four sediment cores collected from beneath the disposal trenches at the Barnwell facility. Gel filtration chromatography experiments using trench waters from the West Valley, New York, disposal site showed an association between /sup 137/Cs and a portion of the trench water dissolved organic content (DOC). Experiments with spiked trench water (/sup 137/Cs and EDTA) indicated that the organic fraction referred to above was not EDTA.
