Abstract:
Water quality parameters, anionic concentrations and uranium levels were measured in groundwater samples collected from Rohil, Sikar District, Rajasthan as a part of radiological baseline survey. This region hosts disseminated uranium deposits. The uranium concentration in water samples showed a mean value of 107 ± 141 μg/L and more than 40% samples crossed the AERB limit. The mean conductivity and TDS of samples were 2221 ± 1513 μS/cm and 1583 ± 1085 ppm, respectively. The mean value of fluoride, chloride, nitrate and sulphate were 2.4 ± 1.4 ppm, 414 ± 466 ppm, 33.70 ± 37.2 ppm and 140 ±133 ppm, respectively. Measured parameters in many samples were above the respective limits set by BIS, AERB and WHO. No particular trend was observed for any of the parameters with increasing distance from the proposed site and no correlation was evident in the measured parameters.
