Abstract
Clay liners are widely used as barriers to arrest the migration of pollutants. These liners are subjected to leaching of various chemicals and hazardous wastes. Migration of heavy metals through the liner material may lead to changes in the soil properties and this, in turn, may affect the performance of liners. In this paper, the change in index and engineering properties of clayey soil due to migration of lead is presented. Pronounced changes in soil properties are noticed when the soil is contaminated with high concentrations of lead. The findings from the present study are important while designing liners in landfills used for containment of pollution due to heavy metals and hazardous wastes.
