Washington University researchers awarded $229K to study lead pipe corrosion

The National Science Foundation, along with the Water Research Foundation, has awarded a pair of Washington University in St. Louis researchers $229,000 in grants to study ways to best control lead pipe corrosion, which can poison drinking water. Daniel Giammar, the Walter E. Browne Professor of Environmental Engineering in the School of Engineering & Applied […]

Lead levels in drinking water spike when copper and lead pipes joined

Lead pipes once used routinely in municipal water distribution systems are a well-recognized source of dangerous lead contamination, but new research from Washington University in St. Louis suggests that the partial replacement of these pipes can make the problem worse. The research shows that joining old lead pipes with new copper lines using brass fittings spurs galvanic corrosion that can dramatically increase the amount of lead released into drinking water supplies.
