Groundwater is one of the crucial natural resources which meets the requirement of drinking as well as for irrigation. Increasing population, erratic distribution of rainfall and their rising demand for water in domestic and irrigation is fulfilled by groundwater resources. Hence, a geo-spatial study was conducted for groundwater sampling for water quality assessment to determine the suitability of water for drinking and irrigation purpose. For this study, five villages around AEC & RI, Kumulur, Trichy, Tamil Nadu were selected as a study area with an aerial extent of 45.1 km2 . For the assessment of groundwater quality, samples from 53 locations were collected from sources like open well, bore well and hand pump. | GIS-based assessment of groundwater quality for drinking and irrigation by water quality index
