ABSTRACT
The arsenic (As) concentration in water resources is very crucial for human life. Arsenic values in water resources in Anatolia can reach important concentrations that need attention. The reason for this is that structural controls such as water-rock interactions and faults during the circulation of groundwater, generally of geogenic origin, affect the circulation of waters. The effect of geogenic As on waters can be seen mostly in monitoring studies in geothermal fluids in Anatolia. Significant As concentrations have been reached, especially in tectonically active regions such as the North Anatolian Fault and Aegean Extensional Fault Systems, and in volcanic fields. In this context, spatial correlation of high As values with structural and volcanic controls was made within the scope of this study.
