Abstract
In the present study, the groundwater quality was tested around the
Gandhinagar sub-watershed covering a neighborhood of 53.63 sq. km, which lies
between north latitudes 12°46′ and 13°58′ and east longitudes 77°21′ and 78°35′ within
the state of Karnataka, India. For the study, data collection includes maps, toposheets,
water quality data, well locations, village locations, etc. The above-said data has been
collected from various government departments of Karnataka. After the data collection,
the base map was prepared using ArcMap. The water samples have been tested and
then used as an attribute database to design thematic maps showing various water
quality parameters.
