本研究评估了溪流水对游泳海滩微生物质量的贡献。Kaelepulu溪的粪便指示菌浓度/100 mL大大超过了USEPA的三个娱乐用水水质标准（200个粪大肠菌群，126个大肠杆菌）。大肠杆菌、肠球菌33株。这些指示细菌的主要来源被确定为环境/非点源（支流、雨水沟、鸭粪、土壤、雨水）。污水排放是另一个来源，尽管是零星的。C.监测沃茨。产气荚膜杆菌是污水污染最可靠的指示物，主要是因为土壤不是这种细菌的主要来源。来自内陆系统的水是从夏威夷州最受欢迎的海滩之一凯卢阿海滩获得的海岸线水样中回收的粪便指标的来源。(C)1997年国际水咨委。出版社：Elsevier Science Ltd
This study assessed the contribution of water from a stream on the microbial quality of a swimming beach. The faecal indicator bacterial concentrations/100mL in Kaelepulu Stream greatly exceeded the three USEPA recreational water quality standards (200 faecal coliform, 126 E. coli, 33 enterococci). The primary sources for these indicator bacteria were determined to be environmental/non-point sources (tributary streams, storm drains, duck faeces, soil, rain). Sewage discharge is another, although sporadic source. Monitoring waters fbr C. perfringens was the most reliable indicator of sewage contamination primarily because soil is not a major source of this bacterium. Water from this inland system was a source of faecal indicator recovered from shoreline water samples obtained from Kailua Beach, one of the most popular beaches in the state of Hawaii.
