摘要

This study evaluates uranium (U) concentrations in drinking water from Dhaulpur district, Rajasthan, using LED fluorimetry. Groundwater samples were collected during pre-monsoon (March 2019) and post-monsoon (October 2019) period to analyze seasonal variations in uranium contamination. Uranium concentrations ranged from BDL(below detection limit) to 23.3 µg/L with an average of 3.7 µg/L in the pre-monsoon (PRM) and from 0.2 to 43.5 µg/L with an average of 7.8 µg/L in the post-monsoon (POM) period. Approximately 3% of 128 samples analyzed exceeded the WHO permissible limit of 30 µg/L. Statistical analysis (t-test) confirmed significant seasonal differences in uranium levels (p < 0.05). Geochemical evaluation indicates that uranium concentrations are higher in the post-monsoon season, likely due to increased leaching driven by rainwater infiltration. Furthermore, human activities, especially agricultural runoff and alluvial sediment deposition, contribute to elevated nitrate levels during the post-monsoon period. The origin of nitrate shifts from geogenic in the pre-monsoon to predominantly anthropogenic in the post-monsoon season. Significant seasonal correlations between uranium and parameters such as nitrate, bicarbonate, total dissolved solids(TDS), electrical conductivity EC, and total alkalinity provide insight into the factors controlling uranium mobility. This study highlights the need for continuous monitoring of uranium to safeguard groundwater quality and public health in Dhaulpur district.
