Marc Edwards, Ph.D.

Marc Edwards, Ph.D., dubbed the “Plumbing Professor” by Time magazine in 2004, is considered by many to be one of the nation’s leading scientific innovators. In 2007, he was named a MacArthur Fellow by the John D. and Catherine T. MacArthur Foundation. An expert in the chemistry and toxicity of urban water supplies in the United States, he has made significant advancements in a number of areas, including arsenic removal and the causes and control of copper and lead corrosion in new and aging water distribution systems. In 1996, he was selected by the National Science Foundation to receive a Presidential Faculty Fellowship. Dr. Edwards is the Charles P. Lundford Professor of Civil and Environmental Engineering at Virginia Tech University.
