Fig. 1 Lxjcations of the two reprocessing plants (H and F) at the Savannah River Plant. 

 The agricultural study area is near the H area. 



The South Field was 145 m by 30 m, and its long axis was oriented to the northwest 

 away from the point of release, a 62-m stack. The North Field shared the same long axis 

 as the South Field but was smaller ( 105 m by 30 m). The centers of the South and North 

 fields were approximately 230 and 420 m, respectively, from the stack. The A soil 

 horizon and parts of the B soil horizon had been removed from the South Field during 

 construction of the reprocessing facility. In addition, some fill dirt had been deposited on 

 the South Field. The North Field had been disturbed less and had a soil profile that was 

 typical for the area. Before being tilled, both fields supported a herbaceous plant 

 community dominated by Andropogon spp., Lespedeza cuneata (Dumont) G. Don, 

 Panicum spp., and Smilax spp. with scattered loblolly pines {Pinus taeda L.). The plant
