Lead Contamination of the Water Supply – the Flint, Michigan Story

Posted September 28, 2016, Length: 20:30

Lead in the water supply is a serious threat to public health and a particular danger to children. Water supplies in many U.S. cities carry unacceptable lead concentrations because of the use of lead pipes, especially where protective water additives are not used. In this podcast we talk with Marc A. Edwards, professor in the Environmental and Water Resources Engineering group at Virginia Polytechnic Institute and State University, who has been actively engaged in both testing municipal water systems for lead, notably in Flint, Michigan and Washington, D.C., and advocating mitigation through the use of additives and the replacement of lead pipes.
