Abstract: | 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 Cl are the major anions in this water. The higher ratios 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 ratio 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, Cl, 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, PI 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. |
