In 2008-2009, fish are were collected from approximately 560 national streams, which included a representative subset of 154 urban river sites, which were in close proximity to urban areas. Site selection included a mix of statistically-selected and targeted sites. ORD/NERL analyzed fish fillets from the 560 stream sampling sites for 22 pesticides, 21 congeners of PCBs, and 8 congeners of PBDEs. Surface water was collected at the 154 urban river sites, and was analyzed for concentrations of almost 50 human prescription pharmaceuticals. Two data files are included, and report the full findings of the chemical analysis in each individual fish or water sample site for each chemical.
