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

孟加拉国戈帕尔甘杰地区的地下水质量没有详细记录。因此，本研究旨在确定研究区地下水质量。采用水质指数和重金属摄入对人体健康的风险来描述水质。水质通过浊度、pH、电导率、总溶解固体以及钠、钾、铵、硝酸盐、铁、锰、锌、铜和砷的浓度进行评估。两个 upazila 的平均浊度、pH 值和总溶解固体均在允许范围内。然而，两个乌帕齐拉的电导率均高于世界卫生组织规定的值，其中 Kotalipara 的浓度较高。 Kashiani upazila 中发现铁和砷浓度超标，但 Kotalipara upazila 中的铁和砷浓度低于检测限。水质指数显示，卡西亚尼乌帕齐拉约61.0%的样品水质较差。然而，约 96.0% 的 Kotalipara upazila 样品质量优良。还通过评估危害商和危害指数来确定因饮酒而造成的慢性健康风险。在卡什阿尼，近 85.0% 的样本对成人来说慢性风险较高，100.0% 的样本对儿童慢性风险非常高。在 Kotalipara，所有样本（几乎 100%）都表明成人和儿童的慢性风险较低。结果表明，卡什尼乌帕齐拉的成人和儿童通过口腔接触砷的致癌风险非常高。
