A study from researchers at the U.S. Geological Survey (USGS) published this month provides strong new evidence that mountaintop removal coal mining in Appalachia is devastating downstream fish populations.
That’s hardly news for long-time followers of the controversy surrounding mountaintop removal, a coal mining practice that involves blowing off the tops of mountains to access thin seams of coal and dumping the waste into valleys below. In 2010, a group of 13 prestigious biologists published a paper in Science, the nation’s premier scientific journal, that found:
“Our analyses of current peer-reviewed studies and of new water-quality data from WV streams revealed serious environmental impacts that mitigation practices cannot successfully address… Clearly, current attempts to regulate [mountaintop removal mining] practices are inadequate.”
The authors of the study published last week found a 50 percent decline in the number of fish species and a two-thirds decline in the total number of fish in streams below mountaintop removal mines in West Virginia’s Guyandotte River drainage. They made this important contribution to the science by using rigorous methodology to isolate several types of waterpollution most likely to have caused these staggering declines.
But a more important contribution of the study may be that it draws the focus of water pollution impacts away from mayflies and other aquatic insects and onto a far more popular and charismatic organism that not only is important to rural people’s way of life, but supports a multi-billion dollar sportfishing industry in Appalachia.
