Abstract

Groundwater in Pakistan is the main drinking water source, highlighting the significance of regularlymonitoring its quality. There have been several examples of high concentrations of elements like arsenic and nitrate ingroundwater that harm human health and the environment. Our aim with this study was to assess the groundwater qualityof the sub-district Bhulri Shah Karim for drinking and irrigation purposes. We collected groundwater samples from 53shallow bore well hand pumps in October and November 2018. We determined the concentration of four cations, fiveanions and other parameters like pH, turbidity, TDS, total hardness, EC, alkalinity, total iron, and arsenic. Thegroundwater was found to be very hard, and the relative abundance of cations and anions was Na+> Ca2+> Mg2+> K+ andCl‾ > HCO3‾ > SO42‾ > NO3‾ > F‾. The concentrations of arsenic and iron varied from 0 to 0.2 mg/L and 0.02 to 3.6mg/L, respectively. We discussed groundwater quality for drinking and irrigation purposes by calculating the waterquality index, sodium adsorption ratio, percent of sodium, permeability index, and residual sodium carbonate. Inconclusion, the groundwater of the studied area is suitable for drinking on average and irrigation. However, some watersamples were high in arsenic content, and some were highly saline and may need some prior treatment

巴基斯坦信德省 Tando Muhammad Khan 县 Taluka Bulri Shah Karim 的地下水质量评估

巴基斯坦的地下水是主要的饮用水源，这就凸显了定期监测其质量的重要性。地下水中砷和硝酸盐等元素浓度过高，对人类健康和环境造成危害的例子不胜枚举。我们此次研究的目的是评估布里-沙阿-卡里姆（Bhulri Shah Karim）分区用于饮用和灌溉的地下水水质。我们于 2018 年 10 月和 11 月从 53 个浅井手泵中采集了地下水样本。我们测定了四阳离子、五阴离子的浓度以及 pH 值、浊度、TDS、总硬度、EC、碱度、总铁和砷等其他参数。我们发现地下水硬度很高，阳离子和阴离子的相对丰度为：Na+> Ca2+> Mg2+> K+，Cl‾>HCO3‾>SO42‾>NO3‾>F‾。砷和铁的浓度分别为 0 至 0.2 mg/L 和 0.02 至 3.6 mg/L。我们通过计算水质指数、钠吸附比、钠百分比、渗透指数和碳酸钠残留量，讨论了地下水的饮用和灌溉水质。总之，研究区域的地下水平均适合饮用和灌溉。但是，有些水样的砷含量较高，有些水样的盐度较高，可能需要事先进行一些处理。
