Abstract

The continuous dosing of micropollutants (MPs), particularly pharmaceuticals and personal care products (PPCPs), from sources including wastewater treatment plants (WWTPs) into surface waters has the potential to alter microbial community structure in both unpreserved and restored wetlands such as those of the Des Plaines River near Wadsworth, Illinois. Of 200 MPs investigated via high resolution LC-MS/MS in that waterway and its tributary Mill Creek, 54 were quantifiable on every sample date across 2 years. Microbial community characterization (performed via 16S rRNA gene amplicon sequencing) indicates unique community structure in areas of restored wetlands, including increased alpha diversity and altered relative abundance of core phylogenetic groups near a riffle structure within the restored riparian zone. Decreases in MP concentration by site relative to restoration structures, particularly across the riffle, suggest that MP removal is due in part to microbial community action and not solely non-biodegradative forms of MP removal.
