Abstract: Low‐level radioactive waste has been produced since the early 1940's. Most of it has been buried in shallow pits at 11 existing sites. Several of the existing sites have performed poorly. Inability to control flow of surface ...

Abstract: Data are presented from four projects in which rates of leakage from ponds lined with clay significantly exceeded the rates that would have been predicted on the basis of laboratory permeability tests. The actual hydraulic ...

Abstract: This paper summarizes the state of the art for in situ conductivity testing of compacted clay soils. Nine methods of testing are reviewed: (1) The Boutwell permeameter; (2) constant‐head borehole permeameters, e.g., the ...

Abstract: This paper addresses practical applications of the type curve method and modified linear curve fitting method described in a companion paper for evaluating the hydraulic conductivity of a vertical cutoff wall. Sensitivity ...
