The U.S. Department of Energy's Office of Environmental Management (EM) team has successfully implemented a unique groundwater remediation system at the Savannah River Site (SRS). By injecting more than 100 million gallons of artesian well water, they're cleaning up shallow groundwater contaminated by decades of coal storage.

The contamination is a legacy of over 60 years of power plant operation, which left soils acidic and metals leaching into the groundwater. Even after coal removal, rainwater continued to pass through the acidic soils, affecting the groundwater.
