In low-income countries like Ethiopia, waterborne illnesses have posed serious public health problems. This study aimed to evaluate drinking water quality (DWQ) and associated factors in Bahir Dar City and the surrounding rural areas in northwest Ethiopia. A cross-sectional study was conducted from January to June 2022 to determine coliform counts and basic physicochemical parameters from the drinking water samples (DWS) collected from urban, peri-urban, and rural sites. A total of 180 DWS were collected from water collection points and households' containers. Potentially pathogenic bacteria were also isolated from fecal coliform (FC)-positive samples and their antibiotic susceptibility profiles were determined. Moreover, the risk factors associated with water quality were assessed. The water quality test results were evaluated against the WHO guidelines for DWQ. Based on the results of this study, only 16.7 and 73.88% of samples met the standards for total coliform and FC, respectively. Moreover, 95.4 and 43% of the isolated bacteria were resistant at least to one of the commonly used antibiotics and multidrug-resistant, respectively. Educating the public on proper drinking water handling, appropriate treatment, and waterline maintenance are needed to safeguard the community from waterborne diseases.

在埃塞俄比亚等低收入国家，水传播疾病造成了严重的公共卫生问题。本研究旨在评估埃塞俄比亚西北部巴赫达尔市及周边农村地区的饮用水质量（DWQ）和相关因素。2022 年 1 月至 6 月进行了一项横断面研究，以确定从城市、城郊和农村地点收集的饮用水样本 (DWS) 中的大肠菌群计数和基本理化参数。从集水点和家庭容器中收集了总共 180 个 DWS。还从粪大肠菌群（FC）阳性样本中分离出潜在致病菌，并测定了它们的抗生素敏感性。此外，还评估了与水质相关的风险因素。水质测试结果根据世界卫生组织 DWQ 指南进行评估。根据本研究结果，总大肠菌群和 FC 分别只有 16.7% 和 73.88% 的样品符合标准。此外，分离出的细菌分别有 95.4% 和 43% 对至少一种常用抗生素具有耐药性，并且具有多重耐药性。需要对公众进行有关正确饮用水处理、适当处理和水线维护的教育，以保护社区免受水传播疾病的影响。
