abstract={Water quality analysis in the Mahanga block of Cuttack district indicate that, ground water quality is controlled by natural geochemical processes such as mineral weathering, dissolution/precipitation reaction, ion-exchange process. The chemical parameters such as Ca, Mg, Na, K, Cl, HCO<SUB>3</SUB>, and SO<SUB>4 </SUB>of groundwater play a significant role in classifying and assessing water quality. With respect to drinking water quality in comparison to BIS (1991) standards, TDS, TA, TH, Ca, Mg, Cl, F, NO<SUB>3</SUB> are found to exceed the highest desirable limits in some cases but not the maximum permissible limit. With respect to irrigation indices such as residual sodium carbonate (RSC), percent sodium (%Na), permeability index (PI), potential soil salinity (PSS), sodium adsorption ratio (SAR), the groundwater are suitable for irrigation purpose. The relative concentrations such as Ca/Mg, Na/Cl, Cl/(HCO<SUB>3</SUB>+CO<SUB>3</SUB>) and base exchange index are used to assess the salinity of groundwater in the study area.},
