Technology development for the design of waste repositories at arid sites: field studies of biointrusion and capillary barriers
The field research program involving the development of technology for arid shallow land burial (SLB) sites is described. Results of field testing of biointrusion barriers installed at an active low-level radioactive waste disposal site (Area G) at Los Alamos are presented. A second experiment was designed to test the ability of a capillary barrier to effectively convey water infiltrating a SLB trench around and away from underlying buried wastes. The performance of the capillary barrier was tested in the field for a barrier of known thickness (2 m), slope (10%), and slope length (2 m), and for one combination of porous materials (a crushed tuff-clay (2% w/w) mixture overlying Ottawa sand) subjected to a known water addition rate. The waste management implications of both studies are also discussed.
