“…This indicates the existence of uranium as a dissolved salt in the form of uranium chloride. A similar trend was reported by many researchers (Singh et al 2003;Selvi et al 2016;Sharma et al 2019). Chloride and nitrate are uranium carriers due to which they show a positive correlation with uranium, consequently, their assurance analysis and correlation are important (Sar et al 2017).…”

The elevated levels of uranium found in 17 state of India which is alarming the radionuclide contamination in groundwater. Chronic ingestion can cause potential harm to humans and living things such as damage to kidney, cancer of liver, lungs, and bones. Present study to assess groundwater quality using multivariate approach and non-carcinogenic exposure of uranium in residents of district Bastar, Chhattisgarh. The concentration of uranium in groundwater samples was ranged from 0.50–26.4 μg/l in 70 samples, with 82% of samples being beyond the recommended limits of International Commission on Radiological Protection. Hierarchical cluster analysis is dividing all sampling locations into 10 clusters explaining similarity of geological condition. Factor analysis has extracted four principal components or factors with 70.20% cumulative variance from the entire data set. CDI has been found above from the reference dose in 34.29, 42.86, and 51.43% for young children, children and adults. The results of Hazard Quotient (HQ) classifying the degree of non-carcinogenic risk which was >1 in 34.28, 45.71, and 41.43% of the samples for young children, children and adults respectively. This study will generate base line data and suggest needs for revision of water quality monitoring plan and preventive water management practice.

“…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.…”

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.

“…Though naturally occurring uranium has always been found in water supplies man's idea of dominance over Mother Nature has resulted in depleting the natural resources. Uranium is found to be increasing in concentration in some parts of Punjab, Kerala, and Tamil Nadu (Singh et al 2003;Bajwa et al 2015;Selvi et al 2016;Shalumon et al 2021).…”

A parametric investigation was carried out to estimate the Uranium concentration and other associated water quality parameters for the groundwater in Deoghar district, Jharkhand. Total 150 groundwater samples have been collected from dig wells, hand pumps, tube wells, etc. for the pre and post-monsoon seasons. A Quantalase Uranium analyzer was used to measure the uranium concentration. The distribution of pH, TDS, DO, nitrate, sulfate, uranium along with the radiation has been determined. It was found that the uranium concentration in groundwater varies from 0.10 to 11.30ppb in pre-monsoon and 0.15–6.50ppb in the post-monsoon which is well below the normal tolerance limit (i.e.30 μg/l WHO). This low availability of Uranium has been attributed due to the existence of a lesser number of rocks containing uranium as a source in that area. An attempt has been made to correlate the uranium concentration with the water quality parameters for both seasons. The correlation data reveals that ORP, nitrate, phosphate, calcium, and magnesium show a positive correlation with uranium concentration for both seasons on the other hand TDS, EC, temperature, DO, fluoride, and chloride show negative correlation. The positive correlation implies that uranium may be present in groundwater as a dissolved salt of these parameters. Comparative studies for the parameters have been done for both the seasons and various factors have been discussed for the occurrence of the same. The annual effective dose associated with the ingestion of uranium by the population of the region has been estimated using USPEA equations.
