Laboratory Study on Effectiveness of Clay Liners to Contain Trichloroethylene (TCE) Contaminated Soils Sharpe Army Depot, California

摘要

Laboratory investigations were conducted to evaluate the effectiveness of compacted clays as liner material to contain trichloroethylene (TCE) contaminated soils. Three types of clays were evaluated: Tests were conducted with water and a concentrated solution of TCE and the permeabilities were compared. The results indicated a significant decrease in permeability when the water saturated clays were exposed to TCE. Several potential factors that can cause the permeability decrease were identified and further investigations were recommended.
