In this study, the hydrogeochemical properties of the groundwater samples in the Karacabey (Bursa) district and surrounding were investigated and health risk assessment was performed. Groundwaters are Ca-HCO 3 , Ca-Mg-HCO 3 and Mg-Ca-HCO 3 facies. The increase of Mg is originated from water-rock interaction related to sandstone and conglomerate levels in different formations. In the study area, it is observed that the waters do not exceed the drinking water limit values in terms of physical properties and anion-cation contents. However, the As content of groundwater ranges between 9-79.1 mg/l. The increase of As geogenic origin associated with volcanic rocks. In some locations, NO 3 , Fe and Mn contents were found to be higher than the drinking water standard values. These increases are thought to be of geogenic and anthropogenic origin. In this study, health risk assessment was made for As, NO 3 , Fe and Mn parameters which exceed drinking water limit values. Hazard Quotient (HQ), Hazard Index (HI) and Carcinogenic risk values of the spring waters for oral (drinking) and dermal (skin) intake were calculated by taking into consideration adult and child individuals. It has been determined that the long-term use of water resources as drinking water may have a negative impact on health. The carcinogenic risk may also be caused by the As element.
