Abstract


 Spatial variations in groundwater quality in the Dosalavanka watershed area of Chittoor District it is located in the northern part of Andhra Pradesh State, India, have been studied using geographic information system (GIS) techniques. GIS, a tool which is used for storing, analyzing and displaying spatial data is also used for investigating groundwater quality information. For this study, water samples were collected from 20 of the bore wells representing the entire Watershed area. The water samples were analyzed for physicochemical parameters like pH, TDS, TH, Cl, So4, F,TA, and NO3-, using standard techniques in the laboratory and compared with the standards. The groundwater quality information maps of the entire study area have been prepared using GIS spatial interpolation technique for all the above parameters. The results obtained in this study and the spatial database established in GIS will be helpful for monitoring and managing groundwater in the study area. Mapping was coded for potable zones, in the absence of better alternate source and non-potable zones in the study area, in terms of water quality.   

 

Keywords:  Garmin GPS, drinking-water samples and spatial interpolation of ARC GIS
