| Abstract |
This Explanation of Significant Difference (ESD) relates to remedial action selected by EPA for implementation at the HH Burn Pit Site in Hanover County, Virginia, in a Record of Decision issued on June 30, 1995 (ROD) (PB95-963910). The selected remedial action included, among other things, excavation and disposal of certain soils and sediments contaminated with polychlorinated biphenyls (PCBs) and extraction and treatment of contaminated groundwater using ultraviolet (UV) oxidation. Advances in the development of High Vacuum Extraction (HVE), an innovative technique for remediating groundwater and soil vapor, have occurred since ROD was signed. In addition, PCBs have not been detected in Site groundwater since a Remedial Investigation (RI) sampling event on May 29, 1992. As long as PCBs remain absent from the groundwater, carbon adsorption is a feasible alternative to the ROD-selected UV oxidation. These developments provide the basis for EPA's reconsideration of the remedy selected for the Site and its conclusion that HVE and carbon adsorption are a more appropriate way of treating groundwater at the Site than the previously selected conventional pumping and UV oxidation. This modification to the groundwater remediation component of the selected remedy does not alter the remaining components of the selected remedy. |
