Urban watersheds are susceptible to

Urban watersheds are susceptible to numerous pollutant sources and the identification of source-specific indicators can provide a beneficial tool in the identification and control of input loads, often times needed for a water body to achieve designated beneficial uses. Differentiation of wastewater flows from other urban wet weather flows is needed in order to more adequately address such environmental concerns as water body nutrient impairment and potable source water contamination. Anthropogenic compounds previously suggested as potential wastewater indicators include caffeine, carbamazepine, N,N-diethyl-meta-toluamide (DEET), gemfibrozil, primidone, sulfamethoxazole, and TCEP. This paper compares the suitability of a variety of anthropogenic compounds to sucralose, an artificial sweetener, as wastewater indicators by examining occurrence data for 85 trace organic compounds in samples of wastewater effluents, source waters with known wastewater point source inputs, and sources without known wastewater point source inputs. The findings statistically demonstrate the superior performance of sucralose as a potential indicator of domestic wastewater input in the U.S. While several compounds were detected in all of the wastewater effluent samples, only sucralose was consistently detected in the source waters with known wastewater discharges, absent in the sources without wastewater influence, and consistently present in septic samples. All of the other compounds were prone to either false negatives or false positives in the environment.

城市流域是容易受到众多的污染物来源和源的具体指标的识别，可以提供一个有益的工具，在识别和控制输入负载，往往需要一个水的身体，以实现指定的有益用途。从其他城市潮湿的天气流的废水流量的差异是必要的，以便更充分地解决这种环境问题，如水体营养障碍和饮用水源污染。人为的化合物，以前建议作为潜在的废水指标包括咖啡因，卡马西平，N，N-二乙基间甲苯甲酰胺（DEET），吉非贝齐，扑米酮，磺胺甲恶唑，和TCEP。本文比较了各种人为的化合物蔗糖的适宜性，人工甜味剂，废水通过检查数据指标发生85微量有机污染物废水样品，与已知的污水点源输入源的水域，而且没有已知的污水点源的输入源。结果统计表明蔗糖的优越性能在美国生活污水输入一个潜在的指标同时检测所有的废水样品的几种化合物，不断检测源水域已知废水排放只有蔗糖，在源的缺席废水的影响，始终存在于脓毒症样。所有其他化合物都容易出现假阴性或假阳性的环境中。
