Soil Bentonite Liner to Control Migration of Iron and Lead Ions

Megha Kulkarni, Ramakrishnegowda C, Nanda HS, Sivapullaiah PV

Compacted soil liners amended with bentonite are widely used to minimize migration of ions like iron and lead. The thickness of the liner for a minimum period is arrived based on the rate of migration of contaminants through the liner.
