Leachate migrations from waste sites or landfills and the release of pollutants from sediment (under certain condi- tions) pose a high risk to groundwater resource if not adequately managed. Their impact on groundwater con- tinues to raise concern and have become the subject of recent and past investigations (Ahmed and Sulaiman 2001; Fatta et al. 1999; Kjelsen et al. 1998; Bjerg et al. 1995; Robinson and Gronow 1992; Cariera and Masciopinto 1998; Loizidou and Kapetanios 1993; Gallorini et al. 1993; Khan et al. 1990; Kunkle and Shade 1976).
Empirical investigations as well as modeling techniques (McCreanor and Reinhart 2000; Lee et al. 1997; Syriopoulou and Koussis 1987; Koussis et al. 1989; Ostendorf et al. 1984) have been used to assess the pollution of groundwater by leachate from a landfill. Groundwater is an important source of drinking water for humankind. It contains over 90 % of the fresh water resources and is an important reserve of good quality water. Groundwater, like any other water resource, is not just of public health and economic value; it also has an important ecological function (Armon and Kitty 1994).
The chemical composition of groundwater is a measure of its suitability as a source of water for human and animal consumption, irrigation, and for industrial and other purposes (Babiker et al. 2007). Therefore, monitoring the quality of water is important because clean water is necessary for human health and the reliability of aquatic ecosystems. This study aims to develop an understanding of the natural
