In the absence of freshwater surface resources, the only alternative to quench the thirst of the human beings is groundwater. The quality criteria, set for drinking purpose, by various agencies are grossly neglected, due to paucity of groundwater owing to indiscriminate exploitation. An attempt is made here to evaluate the quality of groundwater of a socio-economically backward region located in and around the Ingaldhal copper mine area, Chitradurga District, Karnataka, for drinking purpose. Groundwater samples (n=12) collected from 7 villages, were analysed to assess their physico-chemical characteristics. TDS values range from 594-1913 mg/L, pH from 7.61-8.34 and TH from 410-1400 mg/L. Cation concentration ranges are 59-150 mg/L, 49-250 mg/L, 38-290 mg/L and 6-58 mg/L for Ca2+, Mg2+, Na+ and K+ respectively. Anion concentration ranges are 417-574 mg/L, 68-286 mg/L, 63-623 mg/L, 14-162 mg/L, 0-29 mg/L and 0.451-1.43 for HCO3-, SO42-, Cl-, NO3-, CO32- and F- respectively. The results reveal that the average abundance of the major cations and anions is in the order of Mg2+ > Na+ > Ca2+ > K+ and HCO3- > Cl- > SO42- > NO3- > CO3- > F- respectively. The identified types of hydrochemical facies of the groundwater are CaMgHCO3 type (n=3), CaMgSO4 type (n=3) and mixed type (n=6). The values of the major ion concentrations of the majority of the groundwater samples fall well above the recommended standard limit for drinking purpose.Keywords

Present study is an attempt to understand the hydrochemical characteristics of groundwater in Amol- Ghaemshahr region, Mazandaran province in North Iran. Groundwater samples were randomly collected from 77 wells in Amol-Ghaemshahr plain having different depths, varying from 2.4 m to 198 m. The physicochemical parameters such as pH, electrical conductivity (EC) and total dissolved solids (TDS) were measured in addition to major cation and anion concentrations. The abundance of major ions is as follows: Ca2+ > Na+ > Mg2+ > K+ and HCO3- > Cl- > SO42- > NO3-. Thematic maps pertaining to pH, TDS, EC, Cl-, NO3-, SO42- and Na+ were presented in Geographical Information System (GIS) based maps. Different classes in thematic maps were categorized as desirable, permissible and unpermissible based on WHO standards for drinking purposes. The chemistry of water samples from coastal aquifer was interpreted by using classical Piper diagrams. The study indicates that Ca-Mg-HCO3 and Ca-Mg-Cl are the dominant hydrochemical facies followed by Na-Cl and Ca-Mg-SO4 facies. Gibb's plot reveals that the mechanisms responsible for controlling chemical composition of the groundwater are both rock-water interaction and evaporation.Keywords
