As a part of the Superfund Innovative Technology Evaluation (SITE) Program, the U.S. Environmental Protection Agency evaluated the in-Situ Electrokinetic (ISEE) system at Sandia National Laboratories, Albuquerque, New Mexico. The SITE demonstration results show that the ISEE System removed hexavalent chromium in the form of chromate from soil under unsaturated conditions. At SNLs preferred operating conditions, (1) approximately 200 grams (g) of hexavalent chromium were removed during the 700 hours of system operation, (2) the overall removal efficiency for the system was approximately 0.14 g of hexavalent chromium per kilowatt-hour (kWh), and (3) the average removal rate for the entire system was approximately 0.29 g/hour.
