Description 496-503
Due to serious consequences for human health, it's crucial to know how much uranium (U) is present in our drinking
water. The samples of water from various means, viz., hand pumps (HP), tube wells (TB), and public submersible pumps
(PSP) from depths of 190 to 1200 feet, with an average depth of 694feet around the Khetri Copper mine in the Sikar and
Jhunjhunu district of Rajasthan, India have been tested for Physico-chemical contents and their uranium levels. The Pulsed
LED Fluorimetry method is used to determine the U conc. in water samples. Uranium levels in water samples have been
measured to range from 0.68 - 233 μg/l. The U conc. in 28.34% of samples is higher than the WHO & USEPA
recommended limit of 30 μg/l and 18.34% of the samples have U conc. higher than the AERB threshold limit of 60μg/l. The
annual effective dose is also calculated and its mean value is found to be12.29 μSv/y due to the ingestion of ground-water.
The average cancer mortality risk and average morbidity risk are found to be 9.5×10-5 to 1.47×10-4 lower than the threshold
limit of 1.67×10-4 indicating the absence of carcinogenic risks. The chemical risk estimated in terms of LADD (life-time
average daily dose) value is found to be in the range of 0.05–17.15 μg/kg/day. The Hazard Quotient (HQ) for 18.34% of
samples is found greater than unity which indicates the health risk due to the chemical toxicity of U in groundwater. Total
Dissolve Salts (TDS) values in some of the water samples are greater than the acceptable limits for drinking water
recommended by BIS (500-2000 ppm).
