BEST evolved from previous Federal monitoring programs including the National Pesticide Monitor- ing Program (NPMP) of the 1960s, renamed the National Contaminant Biomonitoring Program (NCBP) in the early 1970s, which also screened for elemental contaminants. The U.S. Fish and Wildlife Service (USFWS) participated in the NPMP and maintained the NCBP by monitoring concentrations of persistent contaminants in freshwater fish and avian wildlife through 1986 (Schmitt and others, 1999). The BEST program was initiated in the 1990s to build on informa- tion produced by these earlier programs and to provide more biologically relevant information regarding potential contaminant effects on lands and species under USFWS management. The program was transferred to the National Biological Survey in 1993 and ultimately to USGS in 1996. The LRMN has principal emphasis to identify, monitor, and assess the effects of chemical contaminants on the fish health in the nation’s large rivers. This study was one in a series of BEST-LRMN Program monitoring investigations. Previous studies include the Mississippi River Basin in 1995, the Columbia River and Rio Grande Basins in 1997, the Yukon River Basin in 2002, and the Colorado River Basin in 2003. iv Acknowledgments Staff from the U.S. Fish and Wildlife Service (USFWS) office in Daphne, Alabama (P. Tuttle, S. Floyd, A. Ford), D. Wilkins from the South Carolina Aquarium, and L. Dorsey from the North Caro- lina Wildlife Resources Commission: Division of Inland Fisheries participated in fish collections. J. Isley and T. Grabowski of the USGS-South Carolina Fish and Wildlife Research Unit at Clem- son University, Clemson, South Carolina also collected and aged the fish. D. Cartwright (Leetown Science Center; LSC), A. Donahue (Columbia Environmental Research Center; CERC), A. Griffin (LSC), A. Fazio (Florida Integrated Science Center; FISC), J. Jeran (LSC), R. Lipkin (CERC), J. Scarborough (FISC), and T. Smith (FISC) participated in field dissections. Chemical analyses were conducted by CERC Environmental Chemistry laboratories (B. Brumbaugh, K. Feltz, J. Meadows, M. Tanner, G. Tegerdine, and M. Walther). Laboratory analyses for biomarkers were performed by D. Nicks (CERC), D. Bowling (LSC), and K. Kroll (University of Florida, Gainesville, Florida). D. Bowling (LSC) and K. Spring (LSC) assisted in the histology slide preparation, and B. Martin (LSC) assisted with the macrophage aggregate evaluation. R. Lipkin and K. Chojnacki (CERC) prepared the maps. W. Bryant (USGS), S. Finger (CERC), A. Ford (USFWS), and P. Tuttle (USFWS) reviewed the report and provided additional information. v Contents Preface ...........................................................................................................................................................iii Acknowledgments ........................................................................................................................................iv Abstract ...........................................................................................................................................................1 Introduction.....................................................................................................................................................2 Southeast River Basins Overview ......................................................................................................2 Hydrology and Environmental Setting ......................................................................................2 Urban Areas and Economy ........................................................................................................4 Landownership and Land Use ...................................................................................................5 Dams ..............................................................................................................................................6 Water Quality Impairments and Fish Consumption Advisories ............................................6 Primary Sources of Contaminants to the MORB, ARB, SRB, and PDRB .....................................9 Agriculture ....................................................................................................................................9 Mining and Extractive Industries ..............................................................................................9 Industrial and Municipal Sources .............................................................................................9 Extant Sources of Information on Contaminants in the Southeast River Basins .....................11 Materials and Methods...............................................................................................................................16 Monitoring Methods Overview .........................................................................................................16 Sampling and Field Procedures .......................................................................................................20 Laboratory Analysis ............................................................................................................................20 Composite Sample Preparation ...............................................................................................21 Elemental Contaminants and Moisture Content ...................................................................21 Organochlorine Contaminants and Lipid Content ................................................................22 H4IIE Rat Hepatoma Cell Bioassay .........................................................................................22 Hepatic EROD Activity ...............................................................................................................23 Fish Health Indicators ........................................................................................................................23 General Histopathological Analyses ......................................................................................23 Quantitative Organism-Level Indicators ................................................................................23 Macrophage Aggregates .........................................................................................................23 Reproductive Biomarkers .................................................................................................................23 Gonadal Histopathology ...........................................................................................................23 Vitellogenin .................................................................................................................................24 Sex Steroid Hormones ..............................................................................................................24
