INFLUENCE OF PHYSICO-CHEMICAL AND RADIOLOGICAL PARAMETERS IN THE GROUND WATER OF LAKHISARAI DISTRICT OF BIHAR, INDIASUBHASH PRASAD SINGH AND PALASH KUMAR DUTTAAbstract This paper presents groundwater quality in Lakhisarai district of Bihar, India. Various analytical methods of water were used for various parameters. LED Fluorimetry has been used to measure the concentration of uranium in the ground water samples collected from the selected study locations of the study zone. The concentration of uranium in the collected water samples is found to vary in the range from 0.6 μg/L to 26.04 μg/L with a geometric mean value of 9.81 μg/L during pre-monsoon whereas in the range 0.54 μg/L to 29.86 μg/L with a geometric mean value of 10.70 μg/L during postmonsoon. All the water samples show the concentration of uranium well within the safe limit of 30 μg/L, set by the WHO. Few physicochemical parameters of water such as pH, EC, DO, Total dissolved solids (TDS), ORP, salinity, major cations, and major anions were also measured. Fluoride content in 19.04% water samples during pre-monsoon was found to be greater than BIS acceptable limit of 1 ppm-1.5 ppm. The correlation coefficient among the measured parameters was determined to find the dependence, if any, on the concentration of uranium in the water samples. |
