DIFFUSION IN SATURATED SOIL. II: RESULTS FOR COMPACTED CLAY

This is the second of two papers describing the process of diffusion in soils. The first paper described the background and some methods for measuring the effective diffusion coefficients of inorganic contaminants diffusing in compacted clay soil. This paper presents test data aimed at investigating the efffects of molding water content and method of compaction on measured effective diffusion coefficient values for inorganic species diffusing in comapcted clay soil. Two soils were used in this study: kaolinte and Lufkin clay. Details are described of the soils, and the difussion test program. It is noted that considerable care is required to measure accurate effective diffusion coefficients of inorganic chemicals diffusing in compacted clay soils under laboratory conditions approximating those in the field. These and other study results are presented and discussed.
