INDEXING HYDRO-CHEMICAL QUALITY STATUS OF WATER IN DELHI : A GIS CUM STATISTICAL APPROACH

Abstract

Contamination of drinking water has become a major challenge to environmentalists in rapidly developing countries. As more and more people are exposed to contamination of drinking water, many issues arise that not only involve premeditating the contaminated water, but also preventing similar situations from occurring in future. More effective and integrated water resource management on the regional scale is thus the need of the hour. Any such water resource management strategy must be based on sound, scientific, qualitative and quantitative assessment of the existing resources. Decision makers in environmental fields face the difficult challenges of anticipating the potential biophysical and socioeconomic impacts of managements and policy interventions over regions that may vary dramatically in terms of climates, soils, topography, land use and other factors. However, a water quality index is one of the most effective ways to communicate information on the quality of water t...
