Alan Rauch: Coal-Ash Disaster Pushes Engineer to Design New Fix
Soon after a failed coal-ash pond at a Tennessee Valley Authority powerplant in 2008 spewed waste onto 300 surrounding acres, Stantec Inc. senior engineer Alan Rauch was on a plane to Tennessee. Eventually, he took the lead to design a unique slurry wall around the failed dike, which saved TVA more than $473 million. His innovation may become a fix for utilities nationwide.
