摘要

尽管城市和农村居民都能从适量饮用足够高质量的水中受益,但人工水源的污染程度一直在增加。本研究旨在分别使用基于地理信息系统(GIS)的普通克里格法和层次分析法评估巴希尔达尔市地下水潜力的质量和可用性。建成区地下水中的pH、碱度、大肠杆菌、亚硝酸盐、锰和铁的浓度超过了世界卫生组织规定的限值。地下水水质分布包括69.6%的良水、19.6%的优水和10.8%的劣水。地下水的高潜力,特别是在塔纳湖海岸线沉积区,显示出水质较差。研究结果表明,在地下水可利用性高的地区,应优先改善地下水质量。

Characterizing groundwater quality for a safe supply of water using WQI and GIS in Bahir Dar city, northwest Ethiopia
Although both urban and rural residents benefit from drinking enough high-quality water in the right amounts, the degree of contamination from artificial sources has been increasing. The study aims to assess the quality and availability of groundwater potential in Bahir Dar City using geographic information systems (GIS)-based ordinary kriging (OK) and analytical hierarchy process methods, respectively. The concentrations of pH, alkalinity, Escherichia coli, nitrite manganese, and iron in the groundwater of built-up areas were found to exceed the limits set by the World Health Organization. The groundwater quality distribution contained 69.6% of good water, 19.6% of the excellent class, and 10.8% of the poor class. The high potential of groundwater, particularly in the Lake Tana shoreline sedimentation areas, revealed the poor quality class. The results suggest that improving groundwater quality should be prioritized in areas with high potential groundwater availability.
