Abstract

The objectives of the investigation described herein are; 1. To determine the effects of adsorbed cations on the efficiency of chemical dispersing agents as related to soil permeability reduction. 2. To determine the effects of introducing high concentra-tions of calcium ions in solution into a chemically dispersed soil mass. Tests were conducted in support of the Tennessee Agricultural Experiment Station Project No. H-219 entitled "Pond Sealing." The over-all objective of H-219 is to develop effective and economical treatments for sealing farm ponds under Tennessee conditions. In an attempt to achieve the above objectives, a series of laboratory tests was conducted by mixing various soils with different chemical dispersants. Constant-head permeability values were determined on compacted and treated soil samples in permeameters.
