Abstract

Background and aims: Heavy metals may be originated from natural processes and human activities. that, if exceeded, can lead to risks such as poisoning and carcinogenicity in consumers.Therefore, it is aimed in this study to determine the concentrations of heavy metals in drinking water of Ghaeant County and to estimate the carcinogenic and non-carcinogenic health risks related to consumption of water. Material and methods: This cross sectional study was conducted during 2019. Totally, 24 water well supplying drinking water of rural and urban areas of Ghaenat were selected and the concentration of heavy metals (Pb, Cr, Zn and As) were determined based on the Standard Methods for the Examination of Water and wastewater using an atomic adsorption spectrophotometer. The health risk was estimated based on the guidelines of the EPA and using GIS software. Results: The results showed that mean concentration of Pb, Cr, Zn and As in water resources were 0.0027, 0.0062, 0.8707 and 0.0113 mg/L, respectively. The estimated carcinogenic risk values were high in adults, in 1 well it was very high. The carcinogenic risk was high in all wells for children. The HI values for adults in 18 wells were in range of medium and, in 7 wells was high for children, and in 17 wells it was very high. Discussion: The results show that zinc concentration in all sources and lead concentration, except for one source of other sources, is below international standards. The concentration of chromium and arsenic in drinking water sources is 70% and 44.5% lower than international standards. Due to the high concentration of arsenic and chromium in some of the sources, there is a potential source of contamination with the geological origin for these elements, which requires further studies in this regard, and monitoring of metals must continually be placed on the agenda of the monitoring units. Key words: Heavy metals, Risk assessment, Groundwater pollution
