Groundwater from hand pump could be a principal supply of potable in the large part of rural areas of Mali. Indeed, it was found that this source was the safest to meet water request in remote areas (i.e., rural) of the low-income countries like Mali. However, groundwater quality is changed once external substances are available to contact with the water table. An evaluation of physicochemical and microbial qualities of hand pump water in the rural commune of Pelengana, Mali, was performed. The parameters analyzed include: physical (temperature, pH, and turbidity), chemical (nitrate, and phosphate) and microbiological (both fecal and total coliform bacteria), using standard procedures of analysis. Moreover, API 20E test was used to determine the identities of isolates. Findings have been compared with the WHO drinking water guidelines (or other) values. All physicochemical parameters in hand pump water samples were within the limit recommended by the WHO guideline (or other) values except to turbidity, and nitrate, whereas microbial concentrations during the rainy season were above the WHO acceptable limits. The presence of species such as Escherichia coli, Salmonella and Klebsiella in hand pump waters suggests that water from these sources constitute a threat to public health and is inappropriate for drinking without treatment.

马里塞古贝伦加纳的一些手动泵水的理化和微生物分析

在马里大部分农村地区，来自手动泵的地下水可能是主要的饮用水供应。实际上，已发现在像马里这样的低收入国家的偏远地区（即农村），这种水源是最安全的供水需求。但是，一旦外部物质可用于与地下水位接触，地下水质量就会改变。对马里Pelengana农村公社的手动泵水的理化和微生物质量进行了评估。使用标准分析程序，分析的参数包括：物理的（温度，pH和浊度），化学的（硝酸盐和磷酸盐）和微生物的（粪便细菌和大肠菌总数）。此外，API 20E测试用于确定分离株的身份。将调查结果与WHO饮用水准则（或其他）值进行了比较。手动泵水样品中的所有理化参数都在WHO准则（或其他）值建议的限值之内，但浊度和硝酸盐除外，而雨季的微生物浓度高于WHO可接受的限值。物种的存在，例如手动泵水中的大肠杆菌，沙门氏菌和克雷伯菌表明，这些来源的水对公共卫生构成威胁，未经处理不宜饮用。
