Geohydrologic characterization of proposed Solid Waste Storage Area (SWSA) 7

Status report: A hydrologic framework for the Oak Ridge Reservation

“…Tests of regolith developed on the Dismal Gap Formation (Davis et al 1984) showed a range in porosity of 0.3-0.63, a mean porosity of 0.50, and an average composition of 36% sand, 22% silt, and 42% clay. These results are similar to those of Rothschild et al (1984) and probably are typical of most regolith of the Conasauga Group and the Chickamauga Group. The average composition of regolith on the Knox…”

“…Nonetheless, Kds have been estimated for certain radionuclides in shales on the ORR, as shown below. (Rothschild et al 1984;Davis et al 1984;Meyer et al 1987;Jacobs 1989).…”

Management of spent nuclear fuel on the Oak Ridge Reservation, Oak Ridge, Tennessee: Environmental assessment

“…Groundwater movement in the Melton Valley Conasauga Group of rocks has been extensively investigated (McCold et al 1992;Rothschild et al 1984). The current understanding of Melton Valley is that this area is a groundwater discharge area; recharge of the groundwater in the Conasauga Group occurs at Haw Ridge (Figure 2.1).…”
