Water quality is an important aspect in human health, as the majority of infectious diseases that cause morbidity and mortality in population are water related. The present study was undertaken to assess the quality of water in Kingolwira, Morogoro Rural District, Tanzania. Water was collected from different sites in the village and analysed for a period of six months. Physical, chemical and microbiological qualities of water were examined. The pH of the water ranged from 7.02 to 7.20 and the water temperature ranged from 25.7 degrees C to 27.0 degrees C. The total dissolved solids of the water samples ranged from 110 to 510 ppm. The water contained considerable levels of lead and copper ranging from 0.034 to 0.090 ppm and 0.022 to 0.030 ppm, respectively. Total water hardness ranged from 19.60 to 228.10 ppm as calcium carbonate. The total viable counts and faecal coliform counts ranged from 2.75 x 10(3) to 5.4 x 10(3) c.f.u/ml and 0.93 x 10(2) to 2.1 x 10(2) counts/100ml, respectively. Overall, water supplies in the village were judged as of poor quality. Water is usually used for domestic purposes including cooking, drinking, washing and preparation of infant foods without any treatment. In conclusion therefore, water in Kingolwira village is of poor quality and needs to be treated before consumption. Theres is also a need for the rural population to be educated on hazards of using untreated water. In general, sanitary facilities in rural areas in Tanzania need to be improved in order to avoid health hazards.
水质是人类健康的一个重要方面，因为在人群中导致发病和死亡的大多数传染病都与水有关。本研究旨在评估坦桑尼亚莫罗戈罗农村地区金戈洛维拉的水质。从该村庄的不同地点采集水样，并进行了为期六个月的分析。对水的物理、化学和微生物质量进行了检测。水的pH值范围为7.02至7.20，水温范围为25.7摄氏度至27.0摄氏度。水样的总溶解固体含量范围为110至510 ppm。水中含有相当水平的铅和铜，分别为0.034至0.090 ppm和0.022至0.030 ppm。以碳酸钙计，水的总硬度范围为19.60至228.10 ppm。总活菌数和粪大肠菌群数分别为2.75×10³至5.4×10³ c.f.u/ml和0.93×10²至2.1×10²个/100ml。总体而言，该村庄的供水质量被判定为较差。这些水通常未经任何处理就用于家庭用途，包括烹饪、饮用和制备婴儿食品。因此，综上所述，金戈洛维拉村的水质较差，在饮用前需要进行处理。农村人口也需要接受关于使用未经处理水的危害的教育。总体而言，坦桑尼亚农村地区的卫生设施需要改善，以避免健康危害。
