Identifying major factors controlling groundwater chemistry in predominantly agricultural area of Kattumannarkoil taluk, India, using the hydrochemical processes and GIS

Hydrochemical investigation was carried out in predominantly agricultural area of Cuddalore district, South East India. The objective was to determine the potential factors controlling groundwater chemistry and their seasonal variation. Fifty samples obtained from 37 agricultural boreholes and 13 su...
