Groundwater is the most appropriate and widely used source of drinking water, which is increasingly threatened by pollution from industrial and agricultural activities. The natural water deterioration is an emerging environmental issue throughout the world. The problems become acute where natural pollutants are intensified by anthropogenic activities (Ahmad et al., 2004). The groundwater pollution is mainly caused by disposing of industrial effluents directly into the nearby drains, rivers, streams, ponds, ditches and open fields or agricultural lands (Ullah et al., 2009). Metals are discharged to groundwater by untreated wastes from industries, traffic, municipal wastes, hazardous waste sites, agricultural fields and accidental oil spillages from tankers (Igwilo et al., 2006). The metals and metal ions thus discharged into the environment (soil and water) may enter into the food chain and affect the health of plants and animals (Ahmad et al., 2008;Ahmad et al., 2010;Fardous et al., 2010;Ahmad et al., 2011;Rehman et al., 2013). The movement of different metal and ions in soil is under the influence of various soil related properties (Ibrahim et al., 2012). These metals need to be removed from the media (Irfan et al.
