Engineers raised questions about coal ash pond walls decades ago

For decades, engineers raised questions about the walls of an impoundment pond containing toxic coal ash at the Tennessee Valley Authority (TVA) Kingston, Tennessee coal-burning plant, according to the KnoxvilleBiz.com. They questioned the way the walls were built and argued that they were not initially designed to stand as tall as they did.
