LONG-TERM HYDRAULIC CONDUCTIVITY OF A GEOSYNTHETIC CLAY LINER PERMEATED WITH INORGANIC SALT SOLUTIONS

This paper discusses findings from a long term study conducted by the University of Wisconsin-Madison and Colorado State University where nonprehydrated geosynthetic clay liners (GCLs) were permeated with inorganic salt solutions for more than 2.5 years and as many as 686 pore volumes of flow (PVF). The study's objective was to evaluate the long term temporal behavior of the hydraulic conductivity as a function of concentration and cation valence. The paper describes the hydraulic conductivity of the GCL, in the context of the various termination criteria being used for hydraulic conductivity testing and how hydraulic conductivity obtained when satisfying these criteria relate to the long term hydraulic conductivity at chemical equilibrium.
