Abstract

The study was conducted to evaluate the hydrogeochemistry of groundwater. Twenty-six groundwater samples were analysed for the groundwater quality of Chachro Taluka. The EC and TDS contents in most of the water samples were above WHO (2011) recommended limits. Almost all water samples collected from dugwells located in the study area have elevated concentrations of Na and Cl exceeding the WHO guidelines. Results of Ca, and Mg show that 92% and 96% of groundwater samples were within the prescribed limit respectively. Whereas, HCO3, SO4, and NO3 contnets of 88%, 77%, and 69% respectively are also above the guidelines. Statistical results revealed a dominating trend among the cations of Na+>Ca+2>Mg+2>K+ and anions occur in the order of abundance, as Cl->HCO3->SO4 ->NO3, respectively. The water quality index (WQI) shows that 15% groundwater samples belong to poor category, and 35% water samples were found belonging to very poor category.While, remaining 50% wells were found unsuitable for drinking purpose

巴基斯坦信德省塔尔帕克地区Taluka Chachro地下水水文地球化学评价

对地下水的水文地球化学进行了评价。对26个地下水样品进行了水质分析。大部分水样中EC和TDS含量均高于WHO(2011)建议限量。从位于研究区域的自来井中收集的几乎所有水样的钠和氯浓度都高于世卫组织的指导标准。结果表明，地下水中Ca、Mg含量分别为92%和96%。HCO3、SO4和NO3含量分别为88%、77%和69%，均高于指导值。统计结果显示，Na+>、Ca+2>、Mg+2>、K+阳离子占主导地位，阴离子按丰度顺序依次为Cl->、HCO3->、SO4 ->、NO3。水质指数(WQI)显示，15%的地下水样品属于差类，35%的水样属于极差类。而其余50%的井被发现不适合饮用
