Abstract The groundwater quality of the Gopalganj district in Bangladesh was not well documented. Therefore, this research done to determine study area. water index and human health risk for heavy metal ingestion were used describe quality. performed through estimation turbidity, pH, electrical conductivity, total dissolved solids, concentration sodium, potassium, ammonium, nitrate, iron, manganese, zinc, copper, arsenic. mean solids two upazila within permissible limit. However, conductivity both higher than WHO-prescribed value which Kotalipara. Excess concentrations iron arsenic found Kashiani upazila, but these below detection limit Kotalipara upazila. revealed that roughly 61.0% samples poor about 96.0% excellent Chronic risks due revelation drinking have also been determined by assessing hazard quotient index. In Kashiani, almost 85.0% elevated chronic adults 100.0% very high children. Kotalipara, all (almost 100%) suggested a lower results carcinogenic via oral exposure children
