Environmental Impacts of Mountaintop Mines and Valley Fills on Stream Ecosystems in Central Appalachia
Julian M. Wagner (Editor)
Series: Environmental Research Advances
This book assesses the state of the science on the environmental impacts of mountaintop mines and valley fills (MTM-VF) on streams in the Central Appalachian Coalfields. These coalfields cover about 48,000 square kilometers (12 million acres) in West Virginia, Kentucky, Virginia and Tennessee, USA. This book focuses on the impacts of mountaintop removal coal mining, which, as its name suggests, involves removing all – or some portion – of the top of a mountain or ridge to expose and mine one or more coal seams. The excess overburden is disposed of in constructed fills in small valleys or hollows adjacent to the mining site.
Conclusions are drawn, based on evidence from peer-reviewed literature, and from the U.S. Environmental Protection Agency’s Programmatic Environmental Impact Statement released in 2005, and that MTM-VF lead directly to five principal alterations of stream ecosystems: (1) springs, and ephemeral, intermittent, and small perennial streams are permanently lost with the removal of the mountain and from burial under fill, (2) concentrations of major chemical ions are persistently elevated downstream, (3) degraded water quality reaches levels that are acutely lethal to standard laboratory test organisms, (4) selenium concentrations are elevated, reaching concentrations that have caused toxic effects in fish and birds and (5) macroinvertebrate and fish communities are consistently degraded.
