Effects of Organic Solvents on the Permeability of Clay Soils

摘要

Traditionally, water has been used as the fluid with which to measure permeability of compacted clay soils to assess their suitability for lining hazardous waste landfill and surface impoundments. To determine if permeability of the liner is sufficiently characterized by its being tested with water alone, permeability studies were conducted using both water and a spectrum of organic fluids commonly placed in hazardous waste disposal facilities. Four clay soils, including kaolinitic, illitic, and smectitic clay soils, were evaluated. Results of this study indicate a need to test the permeability of clay liners with whatever organic fluids the liner may be exposed.
