Groundwater cleanup and update of the Savannah River Site experience

A full scale pump and treat groundwater remediation program which addresses a large plume of volatile organic solvents has been ongoing at the Savannah River Site since 1985. The system has recovered over 135,000 kilograms of solvent and is containing the center of the plume. While overall protection is being achieved, reducing the concentration of contaminants to regulatory acceptable levels is problematic.
