From May 11 The Washington Post, comes this article by Darryl Fears.
But a study by the U.S. Geological Survey appears to have answered a critical question about the millions of gallons of chemical-laced water that are injected into the wells to fracture rocks and release trapped gas. Is there any cause for concern when that water is stored later, whether in treatment facilities or special underground wells?
The short answer is yes, said the study’s lead author, Denise Akob, a USGS microbiologist.
“The key take away,” said Akob, who led a team of researchers from Duke University and the University of Missouri in studying a stream near a wastewater storage site in Lochgelly, W.Va., “is really that we’re demonstrating that facilities like this can have an environmental impact.”
