Abstract: The study includes spatiotemporal changes in the groundwater quality in Mysuru City Local Planning Area (LPA) using Geographic Information System (GIS). The secondary groundwater data of 9 stations for 22 years (from 1994 to 2016) was used to analyse the variations. Inverse distance weighted method as well as kriging method of the interpolation are used to prepare the distribution map of physico-chemical parameters of groundwater while overlay method is used to assess temporal changes and prepare groundwater quality zones of Mysuru city LPA. The results of the study show that the quality of groundwater varies both spatially and temporally in Mysuru city. The groundwater quality showed a decreasing trend in all the directional zones due to rapid urban sprawl.

Keywords: Physico-chemical parameters, groundwater, Geographic Information System GIS, kriging, interpolation, Water Quality Index WQI, transect profile
