研究区域Puakko，夏威夷岛。研究焦点Puakko流域污水污染的位置是通过测量地下水威尔斯井和Puakko及邻近度假村海岸线沃茨内的污水指标确定的。染料示踪试验、水质、δ 15 N大型藻类、δ 15 N-和δ 18 O-NO3-测量沿着稳定同位素混合模型相结合，评估了不同类型的现场污水处理系统（OSDS）对水质的影响，并用于预测未来管理措施对水质的改善。该地区新的水文见解Puakō海岸线沃茨的污水指标最高，包括：肠球菌属，产气荚膜梭菌、人类相关拟杆菌和δ 15 N-NO3-。利用δ 15 N-和δ 18 O-NO3-的混合模型结果表明，污水是NO3-的主要来源，在16个海岸线站点中的10个站点中占> 40%。δ 15 N大型藻类测量证实了大多数站点存在污水。在地下水威尔斯井和邻近度假村的海岸线沃茨水域，污水指标较低，δ 15 NO3-表明土壤和肥料。Puakō染料示踪剂测试显示，污水在5小时至10天内到达海岸线，OSDS类型不影响行程时间。水质是相似的，在前面的家庭与不同的OSDS。总之，污水进入Puakō的地下水，而不是OSDS类型，主要控制污水到达海岸线的速度。我们的研究结果强调了普阿科改善污水处理和收集的必要性。
Study regionPuakō, Hawai‘i Island.Study focusLocations of sewage pollution in the Puakō watershed were identified through measurements of sewage indicators at groundwater wells and within Puakō’s and adjacent resorts’ shoreline waters. Dye tracer tests, water quality, δ15N macroalgal, and δ15N- and δ18O-NO3-measurements, along with stable isotope mixing models, were combined to assess water quality impairment caused by different Onsite Sewage Disposal System (OSDS) types, and used to predict water quality improvements from future management actions.New hydrological insights for the regionSewage indicators were highest within Puakō’s shoreline waters, including:Enterococcusspp.,Clostridium perfringens, human-associatedBacteroides, and δ15N-NO3-. Mixing model results using δ15N- and δ18O-NO3-suggest that sewage was a dominant NO3-source, comprising > 40% at 10 of the 16 shoreline stations. δ15N macroalgae measurements confirmed presence of sewage at most stations. In groundwater wells and at adjacent resorts’ shoreline waters, sewage indicators were low, and δ15NO3-was indicative of soils and fertilizers. Puakō dye tracer tests revealed that sewage reached the shoreline within 5 h to 10 d, and that OSDS type did not affect travel time. Water quality was similar in front of homes with different OSDS. In conclusion, sewage is entering the groundwater at Puakō, and the underlying geology, rather than OSDS type, primarily controls the speed at which sewage reaches the shoreline. Our findings highlight the need for improved sewage treatment and collection at Puakō.
