The Karaali Geothermal field, one of the geothermal areas in Turkey, is located 45 km south-east of Şanlıurfa province in southeastern Anatolia. It also covers the area including Karaali village within the Akçakale graben. In addition, Karaali geothermal area is of great importance for Şanlıurfa not only because of thermal tourism and being a greenhouse heating source, but also because it is located in the Harran Plain which has very important agricultural potential for the development of Turkey. In recent studies, direct or indirect uncontrolled discharge of geothermal waters into the nearest drainage channels was shown to adversely affect soil and plants in terms of heavy metal contamination This study aims to determine the direct and indirect exposure to heavy metal pollution originating in geothermal waters with respect to human health. Seasonal sampling was carried out between February - October 2018 at 6 points in total, including the drainage channels (D9, D10, D11, D12 and D13) in the vicinity of Karaali geothermal fluid (KJ). Heavy metal parameters were measured such as Al, As, Co, Cr, Fe, Mn, Mo, Ni, Pb, Sb, Se and V. As a result, it was concluded that the sampling values exceed the values for Al, Cr, Fe, Mo, Ni, Se and V in the regulations that should be taken into consideration for the reuse of water in the drainage channels. Additionally, in nearby 2 groundwater wells (K7 and K8), the limit values were exceeded for Al and Fe parameters according to TSE 266, EPA and WHO drinking water criteria. Finally, heavy metal pollution in the drainage channels affected the wells only in terms of Al and Fe. It was also concluded that the indirect exposure impact due to heavy metal that is carried to soil, plants and groundwater by the re-use of irrigation water is more serious for human health than direct exposure caused by groundwater consumption However, over a certain period of time an increase in parameters exceeding the limit values in terms of heavy metal may also occur.
