Abstract: Assessing the quality of groundwater is important to ensure sustainable safe use of the resources and to preserve the natural ecosystem. Groundwater monitoring is an effort to obtain qualitative information on changes in the ground water storage and changes in the physical, chemical and biological characteristics of groundwater. Groundwater quality in GPREC campus and its premises has special significance as it is the major source of residential and drinking water supply. The present study monitors the ground water quality, relates it to the land use / land cover and maps such quality using GIS techniques for a part of GPREC premises. In the present study, thematic maps such as 6 locations, overhead tanks, main roads, minor roads, etc were prepared in toposheet. Physico-chemical analysis data of the groundwater samples collected at predetermined locations, which forms the attribute database for the study, based on which spatial distribution maps of major water quality parameters are prepared in ArcGIS software. The database, which is present in the form of attribute tables were queried and data related to different themes were retrieved. Analysis is done to find the suitability of water for drinking purpose by calculating parameters such as pH, TDS, EC, TH, Total alkalinity, Sulphate, Chloride, Nitrate, Calcium, and Magnesium. This project will be useful for groundwater department for better planning and efficient management of the resources.
