A study was undertaken in the north-eastern Jharia coalfield of Jharkhand to access the quality of surface water around the mines. In this study, eleven water samples were collected from seepages from coalmine and streams around the coal deposit. These samples were used for analysing the physico-chemical parameters by using a geographical information system GIS (spatial analysis) and raster maps are created. In addition to this Water Quality Index (WQI) was calculated to analyze the overall water quality of various sampling locations. Results show that surface water at mine sites is contaminated and many parameters like Total Hardness, Total Dissolved Solids and Total Suspended Solids exceed the limit prescribed by IS: 10500, 1991 which make the water unfit for use in cooling and various other domestic purposes. This need an immediate attention of the concerned authorities to restore the water quality in the area.
