An attempt has been made to study the groundwater geochemistry in part of the NOIDA metropolitan city and assessing the hydrogeochemical processes controlling the water composition and its suitability for drinking and irrigation uses. The analytical results show that Na and Ca are the major cations and HCO3 and C1 are the major anions in this water. The higher ration of Na+K/TZ+ (0.2-0.7), Ca+Mg/HCO3 (0.8-6.1); good correlation between Ca-Mg (0.75), Ca – Na (0.77), Mg-Na (0.96); low ration of Ca+Mg/Na+K (1.6), Ca/Na (1.03), Mg/Na (0.64), HCO3/Na (1.05) along with negative correlation of HCO3 with Ca and Mg signify silicate weathering with limited contribution from carbonate dissolution. The hydro-geochemical study of the area reveals that many parameters are exceeding the desirable limits and quality of the potable water has deteriorated to a large extent at many sites. High concentrations of TDS, Na, C1, SO4, Fe, Mn, Pb and Ni indicate anthropogenic impact on groundwater quality and demand regional water quality investigation and integrated water management strategy. SAR, %Na, P1 and mg-hazard values show that water is of good to permissible quality and can be used for irrigation. However, higher salinity and boron concentration restrict its suitability for irrigation uses at many sites.
