Wastewater infrastructure is designed, in part, to remove microorganisms. However, many microorganisms are able to colonize infrastructure and resist treatment, resulting in an enormous flux of microorganisms to urban adjacent waters. These urban-associated microorganisms are discharged through three primary routes 1) failing infrastructure, 2) stormwater, and 3) treated wastewater effluent. Bacterial load estimates indicate failing infrastructure should be considered an equivalent source of microbial pollution as the other routes, but overall discharges are not well parameterized. More sophisticated methods, such as machine learning algorithms and microbiome characterization, are now used to track urban-derived microorganisms, including targets beyond fecal indicators, but development of methods to quantify the impact of these microbes/genes on human and ecosystem health is needed.

废水基础设施微生物对人类和生态系统健康的影响。

废水基础设施的设计旨在部分去除微生物。但是,许多微生物能够在基础设施上定殖并抵抗治疗,导致大量微生物流入城市附近的水域。这些与城市相关的微生物通过以下三个主要途径排放:1)基础设施故障,2)雨水和3)经过处理的废水。细菌负荷估算表明,与其他路线相比,失效的基础设施应被视为等效的微生物污染源,但总排放量的参数设定不充分。如今,更复杂的方法(例如机器学习算法和微生物组表征)已用于跟踪城市衍生的微生物,包括粪便指标以外的目标,
