Summary:The multiple barriers concept is used to evaluate possible sites for disposal of radioactive wastes. A satisfactory site would be a nonpermeable, crystalline rock mass (granite or gneiss) under a covering of sedimentary rocks whose groundwater flow characteristics are well understood. Under favorable circumstances the groundwater flow operates as an active barrier , preventing the pollutants from reaching the biosphere. In addition, the depository may be placed where groundwater is nonpotable or salty, minimizing the possibility of future human intrusion. Other barriers are the waste 's form and encapsulation and a low-permeability, high-adsorption backfill. Sites having characteristics similar to those of the hypothetical situation are the coastal plain of Maryland, the Denver Basin Cretaceous shale sequence (except in areas of oil and gas production), and the Illinois basin.
