Greene also tried to claim a single study by one company, which downplayed its scientific validity, proves that valley fills actually improve the water quality of streams they bury.
A recent initial report by the U.S. Fish and Wildlife Service calls that conclusion into question. That report says that valley fills may have widespread impacts on ecosystems, even those well downstream from valley fills.
One unscientific study by an incredibly biased source cannot validate a practice that has buried at least 900 miles of streams in just four states, according to the Fish and Wildlife Service report, which was extremely conservative.
No one knows what such a massive ecological disturbance is doing to water quality, and to related ecosystems. It is insane, not to mention illegal, to allow this to continue on such a massive scale until real studies can determine how much damage is being done.
Southern West Virginia alone has lost at least 470 miles of streams. It is too bad that coal executives aren't forced to calculate the cost of this loss, as well as the disruption to hundreds of residents, before they determine that mountaintop removal is the only economical way for them to mine this coal.
