英文摘要	To supplement other waste disposal operations on the DOE Oak Ridge Reservation, the soils at a potential site for shallow land burial of low-level radioactive waste have been characterized. Proposed Solid Waste Storage Area (SWSA) 7 is located in Melton Valley, east of the current burial facilities in the valley. Physical, chemical, and hydraulic properties of the soils on the site are documented. The thin veneer of soil on proposed SWSA 7 has been mapped in detail and divided into 11 mappable units. In general, the upland soils are well drained, whereas the soils in the lower parts of the site may be poorly drained. Six soil types that are most likely to be affected by waste disposal operations were studied in detail. The soils examined contain little or no carbonate and exhibit low pH. Laboratory studies were carried out to determine the moisture characteristic functions for the six soil types. The laboratory data were combined with field data to produce functions that are directly accessible by numerical models to be used for site evaluation in the future. A total of eighteen soil and sediment samples were collected for determination of their radionuclide adsorption properties. Radioisotopes of I, Cs, Sr, Co, and Am were studied, and all exhibited high Kd's (greater than 23 L/kg) with the exception of I, which had a consistently lower Kd. The cation exchange capacities of the soils averaged 169 meq/kg. Three soil profiles were examined in detail and the mineralogy of the horizons determined. Generally, the southern half of the site appears to be dominated by vermiculite-rich micaceous minerals, whereas in the northern half of the site, kaolinite and micaceous minerals dominate. A preliminary evaluation of the potential erosion on this hilly site was made. Once the site is grass covered, the erosion will be on the order of 0.4 to 4.5 metric tons ha/sup -1/ year/sup -1/.
