Water treatment expert to speak, May 4

Marc Edwards, an author of a recent report concerning traces of lead in the drinking water of several metropolitan areas, will speak at 8 p.m. Thursday, May 4, in McCosh 50. His topic will be "Imminent Endangerment: 'Lead' Astray by the EPA."

Edwards is a professor of civil and environmental engineering at Virginia Polytechnic Institute. An expert in the causes and control of copper and lead corrosion, he has testified before Congress, urging the U.S. Environmental Protection Agency to address the impact of water treatment changes on the safety of drinking water. In an August 2005 report, he and other researchers linked traces of lead in Washington, D.C., water to an EPA-mandated switch by local utilities from chlorine to chloramine as a disinfectant.

The event is sponsored by University Public Lectures.
