An Assessment of Groundwater Quality of Ilkal Taluk, Bagalkot District, Karnataka, India Using GIS and CCME WQI
Groundwater (GW) quality in Ilkal Taluk of Bagalkot district, Karnataka, India needs special attention as it is a significant alternate source of potable water, domestic needs and industrial applications for the people residing in this area. From the geological features of the area, it is evident that the region is comprised of granite and gneiss metasediments whose significant composition is the fluorite mineral. In this study, Spatial Distribution Maps (SDM) were prepared for the water quality parameters analyzed for the GW samples from 32 different locations of Ilkal taluk using Inverse Distance Weighting (IDW) technique of Arc GIS. From the SDM of Ilkal taluk it is observed that concentration of fluoride in all the samples was more than the BIS maximum allowable value of 1.5 mg/l, pH in all the samples was found well within the range, total dissolved solids exceeded the acceptable value in an area covering 638.09 km2 and permissible value in an area of 2.34 km2 and hardness exceeded the permissible value in an area covering 473.87 km2, Nitrate exceeded the acceptable value in an area of 78.89 km2 and Total alkalinity exceeded the acceptable value of 200 mg/l in an area of 649.53 km2. GW quality assessment was done using Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) which resulted in poor ranking. Hence, continuous monitoring and appropriate treatment of the GW to make it fit for drinking and to protect the health of the people residing in this area is a prime necessity.
