Correspondence: Uranium Concentration in Groundwater in Hisar City, India

roundwater quality of a region can influence the health of its inhabitants. A number of studies have so far been conducted on chemometric analysis of groundwater and shown that the major contaminants present in groundwater of Indian territories are salinity, fluoride, nitrates, arsenic and heavy metals. However, some recent studies have reported the presence of natural uranium and other radionuclides, of geogenic origin, in groundwater at several places in India. Uranium is omnipresent and the second heaviest naturally occurring element. It is present in the earth s crust with an average abundance of 1.8 mg/kg.6 Natural uranium mainly consists of 238U isotope (99.27%); 235U and 234U isotopes comprising 0.72% and 0.0055%, respectively.
