“…Patra et al reported that, around the uranium mining sites in Jaduguda, Jharkhand, the concentration of uranium ranged from 0.03 to 11.6 µg/L [1]. In Nadia, West Bengal, uranium concentration ranged from 0.21 to 20.9 µg/L in groundwater samples, reported by Das et al [34]. Similarly, a uranium concentration of 0.1-14.5 µg/L was found in drinking water samples in Patna, Bihar, reported by Kumar et al [2].…”

“…Sampling sites signifies the favourable condition for uranium transport and release in aquifers [2,64,65]. A minor but positive correlation of sulphate with uranium suggests that SO 4 2− ions may be an additional complexing agent for uranyl (UO 2 2+ ) ions in groundwater [34,66,67]. Sulphate shows a strong positive correlation with EC, TDS, total hardness, calcium, total alkalinity, chloride, and nitrate, which confers the parameters' interdependency.…”

“…In addition to this, a good positive correlation of nitrate with TDS is observed. This finding suggests that nitrate may take part an important role in the dissolution of uranium from minerals like uranyl nitrate (UO 2 (NO3) 2 ) [34,63]. Hence it can be said that agricultural nitrate and phosphate fertilization might be the carrier of uranium.…”

“…Higher concentrations are reported from places like Kolar (Karnataka) [27], southwest Punjab and Bhatinda (Punjab) [8,28], Peddagattu and Seripally (Andhra Pradesh) [29], Hyderabad (Telangana) [30], Sirsa (Haryana) [5], Madurai, Tamil Nadu [31] and Central Tamil Nadu [32]. On the other hand, studies carried out in places like Vishakhapatnam (Andhra Pradesh) [33], Jaduguda (Jharkhand) [1], Nadia (West Bengal) [34], and Patna (Bihar) [2] have estimated a lower concentration of uranium in groundwater. The uranium concentration in groundwater is also observed changing with seasons, as reported from India's different places [35][36][37].…”

Uranium concentration has been estimated in 31 groundwater samples collected from the Nalbari district of Assam in pre-monsoon and post-monsoon season. Fourteen other water quality parameters have also been monitored to study their correlation with uranium. The uranium concentration varies from 0.3 to 7.1 µg/L with the mean value of 2.15 µg/L in pre-monsoon and 0.6–10.3 µg/L with the mean value of 2.75 µg/L in the post-monsoon season. The higher concentration of uranium in post-monsoon may be ascribed to the dissolution of uranium from soil sediments in the rainy season. It has been observed that the uranium content in both seasons is far lower than the WHO (2011) permissible limit of 30 µg/L. In both seasons, nitrate, sulphate, and especially phosphate show a positive correlation with uranium, which may be due to different agricultural activities. Agricultural nitrate and phosphate fertilization might be the carrier of uranium in groundwater through dissolution. For all life stage groups, the annual effective dose was appeared to be far below the WHO (2011) prescribed limit of 100 µSv/y. In consideration to adults, the ingestion dose for infants was turned out to be higher. The carcinogenic and non-carcinogenic risk was less than the permissible limits for both children and adults. Both dose value and risk indices were found higher in the post-monsoon season.

Replumbing the Bengal Basin: A Shift in Recharge Driven by Groundwater Irrigation Revealed by Stable Water Isotopes

Groundwater supports agriculture and provides domestic water for over 250 million people in the Bengal Basin. Our analysis of stable water isotope ratios in rain, surface, and groundwater shows that the proportion of groundwater recharge originating from stagnant surface water bodies has increased by about 50% over the last seventy years while the relative contribution from direct infiltration of rain has decreased. This regional shift in the source of groundwater shows how the simultaneous expansion of irrigated rice, excavated ponds and groundwater pumping has changed the hydrologic system by cycling evaporated standing water through the subsurface. Analysis of water isotope data also reveals that most recharge from standing water enters during the latter part of the dry season (February-April), while most rainwater recharge occurs in the early months of the monsoon (June-August) before aquifers fill to capacity and reject additional recharge of rainwater.
