The current study aims to evaluate the seasonal variation in groundwater quality across five different sites in the Sikar district, namely, Piprali (Site 1), Dadiya (Site 2), Yalsar (Site 3), Sabalpura (Site 4), and Gokulpura (Site 5), over a period of one year. The results of the study showcased a seasonal variation in the physicochemical parameters of the water samples collected from different sites, namely, Temperature, pH, EC (Electrical Conductivity), Turbidity, TA (Total Alkalinity), DO (Dissolved Oxygen), BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), TH (Total Hardness), Chloride, Calcium and Magnesium. The results showed that TA, TH, Calcium, BOD and COD were highest in summer season while temperature and turbidity were highest in monsoon season. On the contrary, winter season showed highest levels of pH, DO, chloride and magnesium. Nonetheless, the groundwater from all the tested sites was found to be within the acceptable limits for drinking purposes.
