| 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. |
