Potential interplay of Uranium with geochemical variables and mineral saturation states in groundwater

Abstract Uranium (U) is formed by the interaction of groundwater in aquifer and surrounding rocks. The area chosen for this study a hard rock terrain various lithology South India, which releases U affect quality. Hence, was conducted to understand geochemistry temporal variations with respect saturation state minerals different seasons namely Pre-monsoon (PRM), Northeast monsoon (NEM), Southwest (SWM) Post-monsoon (POM). A total 216 samples were collected, representing (Fissile hornblende biotite gneiss, Charnockite, Quartzite, Granite Flood Plain Alluvium) area. collected analyzed physical parameters such as Electrical conductivity, Total dissolved solids, pH major ions. measured using Laser Fluorimeter. infers that weathering SWM, ion exchange PRM POM anthropogenic process NEM three processes could dominate hydrogeochemistry U. higher concentration has been highlighted, water–rock studied know sources origin it plotted through bivariate ternary diagrams. index made calculated uranium, carbonate, sulfate, silicate phosphate PHREEQC Programme. Uraninite Coffinite are dominant saturated states tend attain near irrespective seasons. With increase seasons, noticed also increasing. Overall, lithological impact their occurring outcome will help policy makers sustainable management safeguard resource region.
