Effects of sediment toxicity from coal mining on endangered mussel populations in the Upper Tennessee and Cumberland river drainages
A draft report and supporting information was produced by this SSP project. A scoping and reconnaissance study was conducted by the US Geological Survey in cooperation with the US Fish and Wildlife Service and National Park Service. Sediment, surface water and pore water samples were collected at 21 sites in the Clinch, Powell and South Fork Cumberland River basins in 2004-05. Three coal ponds (one yard sump and two drying cells) were also sampled in 2005. Surficial streambed sediment ranged from 0 to 47.7 percent coal and was composed predominantly of sand and gravel. Sediment quality guidelines were periodically exceeded at several sites for arsenic, chromium, lead and 22 of 31 polycyclic aromatic hydrocarbons...
