An overview of the Odessa chromium superfund sites: Applications of electrochemical reduction technology

This paper provides a brief background and history of the Odessa Chromium Superfund sites and a synopsis of remedial efforts to date. The selected remedy chosen by the U.S. EPA to remove hexavalent chromium from a groundwater aquifer beneath these sites utilizes electrochemical reduction technology. Although this technology has been applied relatively infrequently in the Superfund program, it offers certain technical advantages in specific applications. The design and operating principles of this technology will be discussed as well as some of the criteria useful in determining its applicability
