ABSTRACT: Water quality assessment has always been a major part of environmental management plans. In thisstudy, the groundwater quality and spatial distribution in the eastern Thrace region was assessed andmapped for agricultural and drinking purposes. Groundwater samples (n = 18) were collected from deepwells in the study area and analyzed for hydrochemical properties for the water quality assessment. TheWater Quality Index (WQI) was calculated for the quantification of water quality for human consumption.The WQI values showed that 52 % of the groundwater samples fall in the “poor” and “very poor” categorydue to agricultural impact. Nevertheless, the majority of the groundwater were suitable for irrigationin terms of sodium absorption ratio (SAR), residual sodium carbonate (RSC), sodium ratio (Na%) andmagnesium hazard (MH).
