ABSTRACT: This paper deals with the assessment of main controls on groundwater chemistry in the aquifer system of Ooeides, Orestiada Region, NE Greece, contributing to the assessment of groundwater and surface water interaction, as well as water-rock interactions in the study area. Statistical analysis and relevant hydrochemical plots were employed in the analysis of groundwater samples from the study area during sampling campaigns for the years 2018, 2019 and 2020. The process included the collection and analysis of hydrochemical, hydrological and hydrogeological information and data regarding the aquifer system of the study area. Based on the statistical processing and the spatial analysis of the relevant results of the research, interesting and useful information emerged regarding: i) the recharge procedure of the aquifer from surface water of rivers and streams in the study area; ii) the relationship of groundwater composition with the type of rock through which water flows; iii) the impact on groundwater quality from anthropogenic activities (cultivation activities, municipal waste). From the elaboration of all the above, interesting findings and suggestions came out, which are considered useful for the optimal management of the hydrogeological regime of the study area.
