Popis: Chahnimeh reservoirs, located in the Sistan and Baluchestan Province in the vicinity of Afghanistan border, are the main sources of drinking water for Zabol, Zahak, and Zahedan cities. Water quality and health risk assessment were evaluated based on water quality index (WQI) method (using analytical hierarchy process method), Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI, heavy metals), and hazard quotient (HQ). Eighty-four water samples were collected and analyzed in September 2017 and April 2018 from four Chahnimeh reservoirs. WQI results revealed that most of the water samples have a good quality (64.75–99.68). The CCME WQI for drinking water is varied from fair to excellent (69–100). Results of health risk assessment indicate that Se (Max HQingestion: 2.38) and As (Max cancer risk: 0.0005 and Max HQingestion: 2.89) and U (Max HQingestion: 0.16) have the highest contributions in chronic risks for both adults and children. Therefore, conducting water quality monitoring for at least 2 years is suggested crucial.
