Analysis of bacterial DNA collected from urban infrastructure can reveal both general and specific characteristics of a city's environment and population. Wastewater and stormwater sewers are a key feature of urban systems and serve as collectors of the "indoor" and "outdoor" microbiomes of a city. Urban runoff contains bacteria from impervious surfaces, soils, and wildlife, while sanitary sewage conveys bacteria from humans. Sewer infrastructure additionally contains its own distinct microbial community that differs from either human or environmental sources. Urban water conveyance systems can therefore ?show what microorganisms are associated with different cities, microbiome characteristics of human populations, and urban impacts on natural aquatic environments.
