Mapping of hydrochemical facies of an urban area: A case study of Raipur City, Chhattisgarh, India

Author(s): Sahoo BK, Das M
Abstract: Raipur, the capital city of Chhattisgarh is located between 21° 10’ and 21° 21’ N latitudes and 81° 32’ to 81° 44’ E longitudes. The city has an area of around 193 sq. km. Physiographically the area is situated in the South Central part of Chhattisgarh basin having gentle undulating topography. The area is underlain by limestone, shale and sandstone of Chhattisgarh Supergroup of rocks which form the major aquifers in the area. Groundwater samples from 29 locations in the city were collected during pre-monsoon period of 2010 and were analysed for major ion concentrations. Hydrochemical facies mapping in the area shows that the groundwater in the area is not much evolved and the predominant water type in the area is Ca-HCO3 type.
