翻译后摘要：一些来源的有机废水化合物（OWCs）的溪流，湖泊和河口，包括污水处理厂的污水，已被很好地记录，但其他来源，特别是潮湿的天气排放污水溢流（CSO）和城市径流，也可能是OWCs的主要来源。 2006年3月至8月收集了废水处理厂（WWTP）流出物、CSO流出物、城市溪流、大河、参考（未开发）溪流和尚普兰湖的样本。与废水相关的许多OWC的最高浓度是在WWTP流出物样品中，但在CSO流出物和来自城市河流的暴雨径流样品中也检测到了一些高浓度的OWC，这些城市河流受到下水道管道或CSO的泄漏。各采样点检测到的化合物总浓度和数量差异很大。最高的OWC总浓度（10 - 100 μg/l）出现在污水处理厂和CSO流出物的样品中。 来自城市溪流的样本中的OWC总浓度范围为0.1至10微克/升，城市溪流-暴雨流样本的浓度高于基流样本，因为来自民间社会组织和泄漏的下水道管道的OWC的贡献。 OWC浓度之间的关系，在污水处理厂-流出物和CSO流出物和城市河流的变化程度的化合物通过正常的废水处理去除。在正常废水处理过程中高度去除的化合物的浓度[包括咖啡因，磷酸三（2-丁氧基乙基）酯和胆固醇]通常与CSO流出物中的浓度相似或高于WWTP流出物中的浓度（范围为约1至超过10 μg/l），因为CSO流出物未经处理，由于暴雨期间CSO排放和近地表源泄漏，城市河流暴雨流样本中的浓度高于基流样本。相比之下，由于稀释，在处理过程中难以去除的化合物的浓度在WWTP流出物中高于CSO。结果表明，CSO污水和城市雨水可以是一个重要的OWC进入大型水体，如伯灵顿湾的主要来源。
Abstract: Some sources of organic wastewater compounds (OWCs) to streams, lakes, and estuaries, including wastewater‐treatment‐plant effluent, have been well documented, but other sources, particularly wet‐weather discharges from combined‐sewer‐overflow (CSO) and urban runoff, may also be major sources of OWCs. Samples of wastewater‐treatment‐plant (WWTP) effluent, CSO effluent, urban streams, large rivers, a reference (undeveloped) stream, and Lake Champlain were collected from March to August 2006. The highest concentrations of many OWCs associated with wastewater were in WWTP‐effluent samples, but high concentrations of some OWCs in samples of CSO effluent and storm runoff from urban streams subject to leaky sewer pipes or CSOs were also detected. Total concentrations and numbers of compounds detected differed substantially among sampling sites. The highest total OWC concentrations (10‐100 μg/l) were in samples of WWTP and CSO effluent. Total OWC concentrations in samples from urban streams ranged from 0.1 to 10 μg/l, and urban stream‐stormflow samples had higher concentrations than baseflow samples because of contributions of OWCs from CSOs and leaking sewer pipes. The relations between OWC concentrations in WWTP‐effluent and those in CSO effluent and urban streams varied with the degree to which the compound is removed through normal wastewater treatment. Concentrations of compounds that are highly removed during normal wastewater treatment [including caffeine, Tris(2‐butoxyethyl)phosphate, and cholesterol] were generally similar to or higher in CSO effluent than in WWTP effluent (and ranged from around 1 to over 10 μg/l) because CSO effluent is untreated, and were higher in urban‐stream stormflow samples than in baseflow samples as a result of CSO discharge and leakage from near‐surface sources during storms. Concentrations of compounds that are poorly removed during treatment, by contrast, are higher in WWTP effluent than in CSO, due to dilution. Results indicate that CSO effluent and urban stormwaters can be a significant major source of OWCs entering large water bodies such as Burlington Bay.
