• Description:
  WATTS BAR RESERVOIR/CLINCH RIVER OPERABLE UNIT ; U. S. DOE OAK RIDGE RESERVATION ; OAK RIDGE, ANDERSON COUNTY, TENNESSEE ; CERCLIS # TN1890090003 ; Previous investigations of the Watts Bar Reservoir have looked at many contaminants, but identified only polychlorinated biphenyls (PCBs) in reservoir fish as a possible contaminant of current public health concern. The purpose of this exposure investigation was to determine whether people consuming moderate to large amounts of fish and turtles from the Watts Bar Reservoir are being exposed to high levels of PCBs, or mercury--a historical contaminant of concern. The exposure investigation results are applicable only to the exposure investigation participants. This investigation is not a research study and the results cannot be extended to the general population or be used to evaluate the need for, or efficacy of, public health measures already in place. ; After screening approximately 550 individuals, 116 individuals met the exposure investigation criteria and volunteered to participate in the exposure investigation. These participants were interviewed for demographic and consumption information, and blood was drawn for PCBs and mercury analyses. The average daily consumption rate of Watts Bar Reservoir fish, based on self-estimated consumption frequency and meal size for fish or turtles, was 66.5 grams per day (g/day). (Average consumption of fish in U.S. adults ranges between 13 and 25 g/day. Turtle consumption is not well characterized.) ; Watts%20Bar%20Exposure%20Investigation.pdf
