In the taxonomy column, “NC” indicates that a particular taxonomic level is not classified. Four indicator groups were reported: sediment (indicator of both forested and urbanized sediment samples), water column (indicator of forested and urbanized water column samples), forested (indicator of sediment and water column forested samples), and urbanized (indicator of sediment and water column urbanized samples).
