Hydrogeochemical Properties and Health Risk Asessment of Drinking Water Sources in Antalya Province, Turkey

Abstract

In this study, hydrogeochemical properties of drinking water resources of Antalya province were examined and health risk assessment was performed. The hydrogeochemical properties, usability and quality status of the waters were examined using the analysis results of drinking water taken from pump stations and springs in May (2020) and October (2020). The waters in the region are Ca-CO3 and Ca-Mg-HCO3 waters. The analysis results of the waters were compared with the drinking water limit values determined by TS-266 (2005) and WHO (2011). According to TS-266, it has been determined that the waters are generally drinkable. However, it was determined that the waters exceeded the WHO (2011) limit values in terms of Mg, HCO3 and TDS values. The "Health risk assessment method" developed by USEPA was used to assess the health risk of the waters and determine their effects on human health. It has been determined that the waters in the study area do not pose a serious risk for human health, but the As content of the waters taken from the tanks is partially high. In addition, it is not recommended to consume these waters, especially by children.
