Abstract
Lead is a heavy metal, which has adverse effect on our health & on the environment also. If lead comes in contact with ground water, the later gets contaminated. Lead builds up in the body over many years and can cause damage to the brain, red blood cells and kidneys. The greatest risk is to young children and pregnant women. Clay particle has porosity of 40 – 70% and permeability (K) value of clay is less than 10-7 cm/s and so the rate of advection transport through clay is very low. Clay has the property of swelling, plasticity, cohesion and adhesion. Low porosity, slow diffusive transport, high adsorption of cations, and plasticity / swelling is among the interesting property of clays. Some clay soils have the ability to act as membrane that restricts the passage of charged solutes. An experimental attempt has been taken in laboratory scale using clay as liner materials to protect groundwater from contamination of Lead.
