Methods/statistical analysis: Bangladesh. Water samples were analysed according to the standard procedures. We calculated some parameters required During the dry season, fifty groundwater samples were collected from different shallow tube wells adjacent to Tista River, Findings: for assessing2+ 2+irrigation water quality. The correlation matrix, hierarchical cluster analysis (HCA), and principal component –Mg 3 3 was the dominant water type, and carbonate weathering was the main hydro geochemical analysis (PCA) were 2−used for −better understanding of groundwater chemistry and categorizing the water samples.
