Risk Assessment for Mercury Releases to the Kuskokwim River from the BLM Red Devil Mine Site, Alaska
Doug Cox, Ph.D., BLM Risk Assessment Specialist and Angela Matz, Ph.D., US Fish and Wildlife Environmental Contaminants Specialist
This presentation describes the Red Devil Mine's risk assessment process, a "multiple lines of evidence" approach developed by the Bureau of Land Management (BLM) to incorporate a number of site-specific risk assessment findings into site decision making. Mercury and other site contaminants from Red Devil Mine and other abandoned mines in the Kuskokwim River watershed have been measured in multiple media, leading to concerns about human and ecological risk. Of specific concern is whether mercury methylation and food chain biomagnification poses a risk to human subsistence consumers of locally caught fish. We discuss a number of data sets used to evaluate these risks, including multi-year telemetry studies to track fish movements in relation to mercury sources throughout the Kuskokwim watershed. Fish tissue concentrations of mercury were also collected from many of the tagged fish and are discussed in the context of site and regional consumption patterns.
