Isotopic-Chemical Framework of Groundwater Aquifer to Study the Pollution Dynamics at Delhi, India

摘要

Introduction Indiscriminate disposal of anthropogenic wastes and leaching of pollutants from these resulted in an ever-increasing threat to the quality of ground water resource base. Large-scale groundwater withdrawal for domestic, commercial, and industrial purposes leads to widespread decline of ground water table. For protection of groundwater from pollution (Singhal et al., 2003 and Singh et al., 1997), it is a matter of concern for the planners and decision makers to clearly characterize the groundwater renewal, quality of water and causes of its deterioration, sources of pollution, trace the movement of pollutants and containment of spreading from known sources. The characteristics of pollutants level and transport in groundwater are associated with variations in one or two parameters at one scale and several parameters at another scale. In order to understand the groundwater system (Glynn et al., 2005) and its hydro chemical and pollutant transport study for the Najafgarh drain basin area, a detailed study has been undertaken about the major ions and isotopic signatures of groundwater of the Najafgarh drain basin area of Delhi (Shivanna et al., 1998).
