Assessing ground water quality index using GIS

The demand for water in Tamil Nadu is steadily increasing day by day. Groundwater resources are very critical in meeting the rising demand. Accessibility to all ground water sources are not easy and same as challenging areas of accessing ground water is increasing these days all due to the intrusion of pollutants down the earth. Neyveli is an industrial town in Cuddalore district of Tamil Nadu, India where the ground water gets contaminated due to mining of coal. As a result, the quality of ground water reduces and monitoring becomes difficult. Here is an attempt to study the ground water quality at various places in Cuddalore district. The Water Quality Index approach is used to evaluate and analyse the ground water quality utilising a GIS-based technology. The hydrochemical properties in water are assessed. The hydrochemical parameters are mapped and analysed using a Geographic Information System (GIS). The findings will be beneficial in identifying the root causes of water quality decline, which can then be adopted successfully in any place with low water quality.
