The geochemical analysis of the shallow aquifer sediments of the area of investigation reveals that they are acidic in nature. The mean electrical conductivity of the deposits is 1.16 dS/m that indicates very low or negligible effects of salinity of the sediments of the Rangpur division. The median values of the concentrations of total organic carbon, total nitrogen and sulphur are 0.20%, 0.02% and 58.68 mg/kg, respectively. The trend of the average heavy metal concentrations of the investigated area can be shown as Fe > As > Cu > Zn. The average concentrations of arsenic of the sediments of the study area are 3.52 mg/kg. Sulphur is significantly, positively correlated with copper and zinc (p < 0.05) and insignificantly and positively correlated with arsenic content of the sediments that indicates that the copper and zinc occur as sulphide minerals. The mean concentrations of arsenic in the groundwater are 1.1793 μg/L. The concentration of all the water samples is below the permissible limit of World Health Organization (10 μg/L). The arsenic content of groundwater shows the positive correlations with the arsenic, iron and copper concentrations of the sediments. This implies that the arsenic of groundwater derived from the geogenic source, like the dissolution of arsenic bearing minerals of the aquifer sediments—pyrite and arsenopyrite. The acidic nature, texture and minor quantities of total organic carbon are the factors that also influence the low arsenic enrichment in the investigated sediments and its release to the groundwater. The contemporary arsenic specification research works showed that As(III) the most common species in natural water and foodstuffs and the arsenic is inorganic from source in Bangladesh.

对调查区浅层含水层沉积物的地球化学分析表明，它们本质上是酸性的。沉积物的平均电导率为 1.16 dS/m，表明 Rangpur 区沉积物的盐度影响非常低或可以忽略不计。总有机碳、总氮和硫浓度的中值分别为 0.20%、0.02% 和 58.68 mg/kg。调查区域的平均重金属浓度趋势可以表示为 Fe > As > Cu > Zn。研究区沉积物砷的平均浓度为3.52 mg/kg。硫与铜和锌显着正相关（p < 0.05) 并且与沉积物的砷含量呈不显着的正相关，表明铜和锌作为硫化物矿物存在。地下水中砷的平均浓度为1.1793 μg/L。所有水样的浓度均低于世界卫生组织的允许限值（10 μg/L）。地下水的砷含量与沉积物的砷、铁和铜浓度呈正相关。这意味着地下水中的砷来自地质源，如含水层沉积物中含砷矿物——黄铁矿和毒砂的溶解。酸性体质，质地和少量总有机碳也是影响所研究沉积物中低砷富集及其向地下水释放的因素。当代砷规格研究工作表明，As(III) 是天然水和食品中最常见的物种，并且砷是孟加拉国的无机来源。
