Abstract: In the present study, the impact of mining activities on groundwater quality around the Korba coalfields covering an area of 530 sq. km which lies between latitudes 2215 and 2230N and longitudes 8215E and 8215E in the state of Chhattisgarh, India was carried out. In this study water samples were collected during the year 2012. The analytical data collected from the sampling points of the well location were used as input data for Arc GIS 9.3 to prepare various thematic maps showing the spatial distribution of water quality and also for calculating water quality index (WQI). Attribute sensitivity analysis was also performed in this present study. Results indicate that most of the areas are highly affected by parameters such as pH, Turbidity and Iron.
