摘要

背景和目标:<;/b>;Ga-Nkidikitlana是南非林波波省北部的一个村庄,位于沃特伯格。该地区以其干燥的落叶林和灌木林生态系统而闻名。这项研究的目的是评估自然活动和人类活动对Ga-Nkidikitlana村饮用水质量的影响。材料和方法:<;/b>;2023年,从三个来源收集了30个水样:河流、钻孔和水库。所有样品被运送到水质实验室进行分析,在那里使用标准的APHA方法。测定了pH、EC、TDS、TH、K、Ca、Mg、Na、Zn、V等水质参数。主成分分析(PCA)显示了各因素与地理位置之间的相关性。& lt; b>结果:& lt; / b>研究发现,水中的阳离子和阴离子呈Na<;sup>+</sup>>Mg<sup>+2</sup>>Ca<sup>+2</sup>>K<sup>+</sup>>Fe<sup>+2</sup>;主成分分析结果表明,河流样品与其他样品存在差异。然而,Ga-Nkidikitlana村的水样被分成三部分,钻孔和水库的水样显示出与钠、镁和钙的相关性。研究还发现,pH值与水的总硬度呈负相关,电导率(EC)与水样的总硬度呈正相关。在所有水样中均检测到总大肠菌群,其中钻孔中大肠菌群含量最高。然而,只有低水平的大肠杆菌<;/i>;在所有样品中均检测到。& lt; b>结论:& lt; / b>水样中的微生物污染水平对土壤灌溉是安全的,但在饮用时应加以监测。此外,水样中的含盐量高于平均水平,表明在使用水作任何目的时都应谨慎。

Investigating the Influence of Natural and Human Activities on Drinking Water Quality in Waterberg, South Africa.

<b>Background and Objective:</b> Ga-Nkidikitlana is a village in the Northern part of the Limpopo Province, South Africa, at Waterberg. The area is renowned for its dry deciduous forest and bushveld ecosystem. The study's objective was to evaluate the influence of natural and human activities on drinking water quality in Ga-Nkidikitlana Village. <b>Materials and Methods:</b> In 2023, thirty water samples were collected from three sources: Rivers, boreholes and reservoirs. All samples were transported to the water quality laboratory for analysis, where standard APHA methods were utilized. The water parameters, such as pH, EC, TDS, TH, K, Ca, Mg, Na, Zn and V were measured. Principal Component Analysis (PCA) was used to show the correlation between the factors and locations. <b>Results:</b> The study found that the cations and anions in the water followed a trend of Na<sup>+</sup>>Mg<sup>+2</sup>>Ca<sup>+2</sup>>K<sup>+</sup>>Fe<sup>+2</sup>. The PCA results showed that the river samples differed from the others. However, the water samples from Ga-Nkidikitlana Village were grouped into three components, with the borehole and reservoir samples showing a correlation with sodium, magnesium and calcium. The study also revealed that pH had a negative correlation with the water's total hardness, while electrical conductivity (EC) had a positive correlation with the total hardness of water samples. Total coliform was detected in all water samples, with the highest levels found in boreholes. However, only low levels of <i>Escherichia coli</i> were detected in all samples. <b>Conclusion:</b> The microbial contamination levels in the water samples are safe for soil irrigation, but they should be monitored for drinking purposes. Also, the salinity levels in the water samples were higher than average, indicating caution should be taken when using the water for any purpose.
