Savannah River Nuclear Solutions (SRNS), the management and operations contractor for the Department of Energy’s Savannah River Site, announced that it has injected more than 100 million gallons of clean artesian well water to neutralize shallow groundwater contamination underneath 33 acres of a former coal storage yard and the associated runoff basin at the site in South Carolina. According to Ashley Shull, senior scientist for the project, “100 million gallons is nine times more water than [is] contained in the Georgia Aquarium in Atlanta.”
