An Urban Stormwater Contaminant Signature: Defining Priority Contaminants for Urban Stormwater Research.

ABSTRACT: Stormwater ponds (SWPs) are a common feature of urban landscapes, designed to manage runoff and reduce flooding. Increasingly, they are also recognized as seminatural habitats supporting aquatic biodiversity. However, SWPs receive complex mixtures of contaminants from surrounding urban areas, and the extent of contamination within the ponds themselves remains underexplored. Most studies have focused on outflows or a narrow set of targeted analytes, limiting our understanding of the exposure risks for organisms residing within these systems. To address this gap, we assessed contaminant profiles in 21 SWPs across a highly urbanized city in Ontario, Canada, using three complementary sampling approaches: time-integrated water samples, biofilm on artificial substrates, and organic diffusive gra
