Measuring Performance of Clay Containment Barriersby Walter E. Grube, Jr., U.S. Environmental Protection Agency, United States,
Abstract: Clayey soils compacted to engineering specifications are widely used as structures for hydraulic containment. Current applications include landfill liners, landfill covers, pond liners, and containment dikes; groundwater control using slurry trench cut-off walls is a closely related application. Regulatory requirements for performance specify low permeability. Compatibility is most commonly measured by noting changes in laboratory hydraulic conductivity during permeation by selected liquids. Research has provided reliable methods to evaluate the performance of compacted soil liners. Hydraulic performance evaluation of barrier dikes and groundwater cut-off walls is more complex than with broad expanses of relatively flat compacted soils.
