ABSTRACT
Ground water is a significant natural resource used for many purposes. Present study was carried out to evaluate the concentration of some specific heavy metals in the groundwater of Mendhar town, Jammu and Kashmir, India. Groundwater samples were obtained from ten distinct locations within the Mendhar town and subsequently designated as GW1, GW2, GW3, GW4, GW5, GW6, GW7, GW8, GW9, and GW10. The value of temperature, pH, TSS, electric conductivity, and hardness was found to vary throughout the samples collected. The concentrations of heavy metal ions in ground water samples were found to be in the range of 0.29 mg/l to 10.47 mg/l for iron, <0.5 mg/l to 2.1 mg/l for manganese, <0.05 mg/l for nickel and lead, <0.003 mg/l for cadmium, and from 0.001 mg/l to 0.041 mg/l for arsenic. The fluorides concentrations were found to be in the range of 0.34 ppm to 1.89 ppm. The findings were compared with the National Drinking Water Quality Standards (NDWQS) to assess the present state of the water in the town. The result of the study indicates that the groundwater of Mendhar town requires some degree of treatment before consumption in order to prevent negative effects on human health.
