The key observations on the study concerning the geostatistical appraisal, hydrogeochemical environment of major ions (cations and anions) as well as groundwater suitability from the part of Balaghat District (MP) latitude 21°31ʹ42ʺ: 21°43ʹ11ʺ N and longitude 79°50ʹ30ʺ:80°11ʹ30ʺ E., Central India are presented here. The pH (7.3 to 8.6) of the groundwater samples and range of EC values (50-5080 μS.cm-1) typically clarify the alkaline nature and the involvement of diverse processes (geogenic as well as anthropogenic) deciding the hydrogeochemical environment of groundwater. This prominent behavior is the result of the conductivity in groundwater, which is the consequence of ion exchange along with the solubilization processes during the rock-water interaction and also represents anthropogenic activity. The abundance succession of cations is Ca2+ > Na+ > Mg2+ > K+, while the profusion sequence of anions is HCO3- > Cl- > NO3- > SO42- > F-. The positive correlation among the pair of Ca2+ with Mg2+ (r = 0.657), Na+(r = 0.691), and HCO3- (r = 0.842) as well as the high positive association between K+ and SO42- (r = 0.856), plus K+ and NO3- (r = 0.779) unravels the derivation of ions from the geogenic origin and the agro-chemical derivation of ions respectively. The three factors (1:6.350, 2:2.732, and 3:2.697), having a total variance of 87.923%, correspond with the geogenic factor, anthropogenic factor, and alkalinity factor, respectively. The groundwater from the study area is suitable for drinking and irrigation purposes with a slight threat of exchangeable sodium.
