摘要

Environmental pollution by chemical pollutants such as heavy metals, radionuclides, and anionic constituents such as sulfate and nitrate originated from mines and mining operations can become a very important source of contamination in water. Pollutants mainly present in the chemical industrial wastes as well as in the low level liquid releases from the nuclear fuel cycle. The solid hazardous radioactive wastes arising are usually disposed of in near surface/shallow land burial facilities. The heavy metals components of these solid wastes (radioactive and stable) could find their way either into the ground water through infiltrating water or to the soil by runoff. In this study, an approach is made for distribution of pollutants in ground water collected from seven locations around the premises of a uranium mining site, Turamdih located at Jharkhand state of India. Major and trace elements such as Na, K, Zn, Ni, Mn, Fe, Pb, Cu, Al, Ba, Mo, and U, etc., were analyzed using inductively coupled plasma-atomic emission spectrometry and differential pulse adsorptive stripping voltammetry. Sulfate, nitrate, chloride, and fluoride were analyzed using ion chromatogram. Bicarbonate was analyzed by titration method.
