During rainy season (June to August), 70 groundwater samples from shallow and deep aquifers were collected from Dinajpur Sadar Upazila, Dinajpur, Bangladesh. The water samples were analyzed for the major cations: (Na<SUP>+</SUP>, Ca<SUP>2+</SUP>, Mg<SUP>2+</SUP>, K<SUP>+</SUP>, Cu<SUP>2+</SUP>, Mn<SUP>2+</SUP>, Fe<SUP>2+</SUP>) and anions: (Cl<SUP>−</SUP>, CO₃<SUP>2−</SUP>, HCO₃<SUP>−</SUP>, SO₄<SUP>2−</SUP> and NO₃<SUP>−</SUP>). Water samples contained Ca<SUP>2+</SUP>, Mg<SUP>2+</SUP> and Na<SUP>+</SUP> as dominant cations and HCO₃<SUP>−</SUP> and Cl<SUP>−</SUP> as dominant anions. Based on SARconductivity plot, the groundwater samples were classified into C2S1 and C1S1 classes. All water samples were under ‘very good’, ‘good’ and ‘permissible’ categories according to Wilcox diagram. The chemistry of groundwater is dominated by silicate weathering and (Na<SUP>+</SUP> + Mg<SUP>2+</SUP>) and (Cl<SUP>−</SUP> + SO₄<SUP>2−</SUP>) accounts for about 55% of cations and anions. The contribution of (Ca<SUP>2+</SUP> + Mg<SUP>2+</SUP>) and (Na<SUP>+</SUP> + K<SUP>+</SUP>) to total cations and HCO₃<SUP>−</SUP> indicates the domination of silicate weathering. The concentrations of the major parameters suggest that water quality of shallow and deep tube wells in the study area was satisfactory for drinking and irrigation water.
