Hydrogeochemical assessment of groundwater in shallow aquifer of greater Noida region, Uttar Pradesh (U.P), India

Abstract

Fresh water is needed for the survival of all living organisms to keep them healthy, safe and clean. Major part of this fresh water is obtained from groundwater. It is observed that the groundwater has been polluting due to anthropogenic activities and affecting the human beings, livestock soil nutrients by mass and environment in certain areas. The paper presents hydrogeochemical assessment of groundwater in shallow aquifers of Greater Noida region. Therefore, various physicochemical parameters such as pH, TDS, EC, TH and major ions, i.e. Cl−, SO42−, NO3−, Na+, K+, Ca2+, Fe2+, Mg2+, CO32− and HCO3−, have been analysed in the present study using standard procedures. The results of major constituents were compared with the water quality standards prescribed by WHO. From the analysed samples, different indices such as soluble sodium percentage (SSP), sodium adsorption ratio (SAR), residual sodium carbonate, magnesium adsorption ratio, Kelley’s ratio and permeability index were characterized in the study. Results delineate that the groundwater is suitable for drinking and irrigational use.
