This study aimed to evaluate the overall groundwater hydrogeochemical evolution and suitability for drinking in Andasa watershed (Northwestern Ethiopia). To achieve this, analyses of hydrogeochemical, multivariate (PCA, HCA), correlation matrix, and Water Quality Index (WQI) methodologies were employed. A total of 64 groundwater samples which had been collected during winter season (February-April, 2018) were assessed for ionic and composite variables (major physicochemical and composite

The study results revealed that major ions dominating are Ca>Mg>Na>K and HCO 3 > Cl>SO 4 > NO 3 > PO 4 > F for cations and anions, respectively.
