Philip L. Sibrell is a research engineer with the U.S. Geological Survey, at the Leetown Science Center in Kearneysville, WV. He is currently investigating the application of acid mine drainage residuals for the recovery of phosphate from agricultural and municipal wastewaters. Prior to his employment with the USGS, Dr. Sibrell worked at the U.S. Bureau of Land Management, the U.S. Bureau of Mines, and in the mining industry, as an engineer conducting research in resource recovery and environmental restoration. He is also a professional engineer, and has over 100 publications and presentations. He received his B.S. from the Colorado School of Mines, and M.S. and Ph.D. from the University of Utah, all in Metallurgical Engineering.
